  • Reflecting on Moving a Hoard of Vintage Computers Through Brooklyn’s Streets

    small office space filled with vintage computers on shelves

    I’ve written some about starting the Retrocomputing Archive at City Tech in my cramped desk area in Namm 520 here and here, but I don’t think I’ve written about how I moved the bulk of the lab’s holdings that belong to City Tech from one building to another.

    At a semi-enclosed campus, it might seem relatively easy to move equipment around, but when your campus is like City Tech’s, which is essentially a clusters of buildings on busy, big city streets with security and protocols it can be a real headache. Here’s how the move went down.

    In 2015, I learned through Mary Nilles, my dearly departed English Department colleague, that Stanley Kaplan, Senior CLT Assisting the Dean of the School of Technology and Design, had been keeping a collection of forgotten, vintage computers in a closet on an upper floor in City Tech’s Vorhees Building and the dean wanted the closet cleared out.

    I reached out to Stanley who gave me a tour of the large closet’s treasures seen below.

    I told him that I definitely wanted to move the computers into my office for the Retrocomputing Archive, but I would need to figure out the logistics of it since I didn’t have a car to move everything from one building to the next and a cart to carry the items from the top of Vorhees to the street and then from the street into the bowels of the Namm building where my office is.

    Red line indicates the path that I walked from Vorhees to the Namm Building--including my path within the Namm complex and its elevators.

    I already had nylon straps and plastic wrap from our move to New York from the year before, which I could use to secure everything on a cart, which I didn’t have. So, I purchased up a heavy duty utility cart from Lowes for about $60 (I just looked and the price is up to $130 now!), and carried it boxed (~35 pounds) across the parking lot, down the street, up the stairs to the above ground subway at 4th Ave/9th St, up the steps at Jay St/Metrotech, two blocks down Jay St into the Namm Building, elevator ride up, and dropped it next to my desk exhausted. I assembled it in the office (I had considered assembling it in the Lowes parking lot, but it would have been too awkward to carry up the steps at the 4th Ave/9th St station.

    Utility cart

    For each load of computers from Vorhees to Namm, I put the heaviest equipment on the bottom and completely filled the lower shelf space to give it as low a center of gravity as possible. I stacked the top as reasonably as I could. I strapped it down and used the plastic wrap to secure smaller items that might wiggle loose during the rattly trip through Brooklyn.

    There were pros and cons about moving the computers from Vorhees to Namm. Leaving Vorhees and walking to Namm on Jay Street is down hill. However, the weight of the computers on the cart made it a strenuous task to hold the cart back from careening down the hill. The sidewalk is also uneven, broken, and pieced together with different kinds of material, which had to be navigated over and around. And, of course, there were the pedestrians, which occasionally made the move like a game of Frogger.

    I was able to move the bulk of the equipment in three trips. I might have gone back to pick up a few other things, but the second trip also turned out to be the most stressful. I never had any trouble with security at the entrance of Vorhees. I showed them my faculty identification and told them that I was taking the equipment to Namm. During the first trip into Namm past security, I wasn’t questioned about the equipment. Probably because logically I am bringing things into the building rather than attempting to walk them out, which I imagine happens on occasion.

    But, on the second trip into the Namm building, security stopped me and grilled me about what I was doing. Eventually, they led me to the security office on the first floor where I had an unpleasant conversation with the former public safety director about processes, protocols, and policies that admittedly serve a purpose in most cases but in an edge case like this.

    Despite the computers no longer appearing in any equipment databases, Stan and I had to fill out overzealous paperwork that had to be signed off exiting and entering a building. Individual items’ serial numbers weren’t checked against the paperwork, so it seems to have been bureaucratic onanism that added unnecessary labor to an already difficult project.

    Nevertheless, I moved the equipment into my limited office space and later purchased garage storage shelves to hold most of the larger computers with others on top of my official issued bookshelf and desk and others stacked into my filing cabinet.

    And, the utility cart came in handy when we received the first 160 box donation that inaugurated the City Tech Science Fiction Collection.

  • Vintage Computer Festival Southeast (VCFSE 2.0) 2014

    Georgia Tech Librarians Sherri Brown, Lizzy Rolando, Alison Valk, and Wendy Hagenmaier

    For the second Vintage Computer Festival Southeast (VCFSE 2.0) in 2014, I went with my Georgia Tech Library colleagues Sherri Brown, Lizzy Rolando, Alison Valk, and Wendy Hagenmaier (I wrote about the first VCFSE and shared photos last week here).

    For me, it was great to bridge my professional and hobby worlds–one about studying and preserving our software and hardware digital culture and one about geeking out about retrocomputing–fixing it, using it, and playing with it. Sharing this event with my colleagues who were also negotiating these two overlapping worlds made it memorable to me.

    Below, I share photos from the Digital Archivists presentation panel and photos of the Apple Pop-Up Museum and other installed exhibits, and many photos from the individual exhibitor hall.

    When we first got there, we had a chance to talk with the founder Lonnie Mimms (right) who was wearing a green t-shirt emblazoned with the rebranding for the space as the Computer Museum of America.

  • Vintage Computer Festival Southeast (VCFSE) 2013

    Bob, Paul, and Mark outside the 2013 Vintage Computer Festival Southeast

    On April 20, 2013, I attended the first Vintage Computer Festival Southeast outside Atlanta, Georgia at what is now the Computer Museum of America with my friends Mark, Paul, and Bob. This was the spring of my first full year back in Atlanta after becoming a Brittain Fellow at Georgia Tech in Fall 2012. It was a good day like old times before I went to grad school.

    The following year, I co-presented with Wendy Hagenmaier about Vintage Computing at Georgia Tech, which I blogged about here. I will post photos from the 2014 VSFSE next week.

    IMSAI 8080 (WarGames)

    If you’ve seen the film WarGames (1983), you know what kind of mischief you can get up to with a tricked out version of an IMSAI 8080.

    The Big Three: Radio Shack TRS-80, Commodore PET, and Apple II

    I often regale my students with tales of the rise of the personal computer with the big three mass manufactured models: Radio Shack’s TRS-80, Commodore’s PET, and Apple’s Apple II (though, it’s actually an Apple IIe pictured below).

    Commodore VIC-20, Commodore 64, and Amiga

    I didn’t know anyone with a VIC-20 or Commodore 64 growing up. Mark told me about having a VIC-20 when he was younger. After my trials with the Tandy Color Computer 3, my first GUI-based computer was an Amiga 2000HD. I used it for years for writing, drawing, and gaming until a tree branch attached to a long strand of Spanish moss swung Tarzan-style into my bedroom window and hit the back of the Amiga. It never ran again after that strike.

    Years later, I got another Amiga 2000 from someone at a Goodwill auction. He had won the pallet that I wanted that included the Amiga. I don’t remember what I paid him for it, but I stored it at my used computer stall at Duke’s Y’all Come Flea Market in Darien, Georgia. We had a falling out and I abandoned what I still had in the stall, which included the Amiga. I never found out if it still ran or not.

    Radio Shack TRS-80 and Color Computer Series

    My first desktop computer was a Tandy Color Computer 3 that I hooked up to the family console TV. While I did all that I could with it, I think my mom recognized my frustrations. I wanted to make it work so badly after not having a computer and wanting one for so long. The next Christmas, my folks gave me a Commodore Amiga 2000HD, which was light years ahead of the CC3.

    Quadra 700

    I had a Quadra 700 when I lived in Atlanta with Y. I put it in a box and left it with my folks in Georgia when we moved to NYC. Where it is now is anyone’s guess. There are many hiding places for a small box with this tiny powerhouse of a Mac. I hope to find it again one day.

    Portable Macintosh and Powerbook Line

    My first laptop was a PowerBook 145B, which was my companion during my last two years of high school and the beginning of college of Georgia Tech. Later, I owned a PowerBook G4, iBook G3 (the result of a trade with my friend Kenny), 15″ MacBook Pro (2006), 12″ MacBook (unibody, 2008), and 15″ MacBook Pro (2012–Y still uses it).

    Apple Macintosh TV

    20th Anniversary Macintosh

    When the 20th Anniversary Macintosh debuted, my friend Chris and I lusted after it. It was a sexy computer, but it had an out of this world price tag of $10k (though, that included having a technician deliver, setup, and demo the computer in your own home). In retrospect, it was a terrible product that ignored what the original Macintosh represented as an every person’s computer. This computer was about style and prestige and money. A lot about what Apple represents today after Steve Job’s passing seems to be drifting back toward what this computer represents.

    Network Server 500/132

    Macintosh Add-Ons

    The Apple TV/Video System was an expansion card that gave you a TV tuner and video inputs for your Mac. The PowerCD was an external SCSI CD-ROM drive for Macs that might not have a CD-ROM drive built-in. And the QuickTime Conferencing Kit included a camera and software for video conferencing and collaborative tools like a shared whiteboard–back in 1995.

    Apple Newton

    The thing that used to burn me up when Apple released innovative products like the Newton, popular media like SNL would shit all over them, which would turn the general conversation away from what the products could do and had the potential to do towards the limitations and lack of imagination by those folks who would otherwise never purchase or use those products. It wasn’t criticism. It was product assassination. Had that not happened, I think the Newton would have been in a stronger position that might have let it develop further before getting killed off.

    It seems like the Internet and social media provides a force or pressure against these negative megaphones of the past. However, there’s equally a lot of fanboys and cheerleaders who don’t temper their enthusiasm with a little bit of reality.

    iMacs and G4 Cube

    My first experience with an original Bondi Blue iMac was soon after its announcement. I was working at NetlinkIP on St. Simons Island, Georgia when a client called asking for help setting it up. I drove out to a very nice house on the island, unboxed, and configured it to dial up to the Internet. Admittedly, I took longer than was necessary so that I could thoroughly check it out.

    Later, my friend Bert got a G4 Cube. Despite its complete lack of internal expandability beyond upgrading its RAM or hard drive, he used his beyond what I think most people would. Every USB port was used for devices or hubs and it was connected to his stereo system. He used it for a lot of graphics and video work and showed how it really was a supercomputer in a small package.

    I had a 17″ Luxo iMac for awhile in the early 2000s, but I sold it before I built another desktop PC using an AMD Athlon 2500+ CPU. While I had it though, I liked its crisp 17″ LCD and it was a powerhouse for some of the video editing projects that I did at the time.

    Portable Computing Miscellaneous

    I really like the concept of pocket computers. When I was in middle school, my grandparents gave me a Radio Shack PC-7 Basic Programmable calculator. It looked like a calculator with a built-in soft cover that had a ABC keyboard layout. Considering its programmability, it was the first computer that I owned. The only digital device I had before that was an Atari 2600.

    Miscellaneous Computer Demos

    Jim Steiner’s Tic-Tac-Toe Computer Built in 1961

    Pictured below with his tic-tac-toe computer that demonstrates binary digital logic, Jim Stiner’s creation still works. Before we left the VCF, I enjoyed speaking with Mr. Steiner about his project inspired by a humanities class. I was reminded of Steve Job’s 2011 special event demo for the iPad 2 where he talks about Apple’s DNA marries technology with the liberal arts. That concept seemed apt for Mr. Steiner’s project, too.

  • Google Glass, POV, and Augmented Reality

    When Google Glass debuted, I thought it was a cool piece of tech. Recording POV video and photos for my maker-oriented work and getting updates unobtrusively in class, meetings, and conferences were its main selling points to me. I wrote about some of my experiments with Google Glass and LEGO here. Unfortunately, it had its hardware and software limitations. One person who I interacted with took extreme umbrage with it. And, Google’s waning support over the years didn’t help either. Eventually, I sold it on eBay as I had stopped using it altogether.

    Use in Professional Settings

    When giving presentations that related to interfaces and new media, I often wore Google Glass as a prop, which I would reference in my talk. Had I been very clever, I would have used it like a teleprompter, but it was often easier to read from notes printed or on a tablet in hand.

    I did get told off by someone who I didn’t know shortly before my co-presentation with Wendy Hagenmaier on “Digital Archives and Vintage Computing at Georgia Tech” at the Southeast Vintage Computer Festival 2.0 in Roswell, GA on 4 May 2014. I don’t know who she was, but she zeroed in the Glass, got perilously in my face, waved her hand dangerously close to my face and the Glass, and demanded that I stop recording video of her. I stepped backward and tried to explain that it wasn’t recording video or taking photos–I only had it conveying messages from my phone at the time. The thing about the Glass is that the computing unit got very, very hot–uncomfortably hot–if you recorded video for more than a minute or two. Of course, it would eat through its battery, too. So, full time recording wasn’t really possible. It did have a beta feature to take a photo when you blinked, but I never left the feature on as it resulted in lots of useless photos and depleted the battery. She was pissed and was having none of my explanation. Since we weren’t really having a discussion, I just said that I was sorry and walk away. It was an unnerving encounter since she was walking around with the organizer who remained silent during the exchange. Perhaps it had more to do with it being a Google product? What about it being a public space? What about the many other participants carrying smartphones with cameras as well as dedicated point-and-shoot and DSLR cameras? Perhaps she gained her intended effect as I was more cautious about where and when I wore them.

    For such an encounter, it would have been nice if the Glass had a built-in lens cover that lets others around the Glass wearer know at a glance if the lens was exposed or not, or if the camera part could have been modular in some way so that the wearer could have the AR but remove the camera when it wasn’t needed.

    Google Glass Kit

    I opted for the Google Glass Explorer kit that included detachable sunglasses. The kit included a single ear speaker that connected to the computing unit on the right side. An AC charger, USB cable, and felt carrying cases for the Glass and sunglasses were included, too.

    Before Its Time?

    Wearable technology like this seems inevitable. Good hardware and software design combined with killer apps/features would make this an invaluable tool, I think. The battery life and heat problems were downplayed during the initial public release, but they were real problems that robbed Glass of the bare minimum of functionality that it deserved. Had Google cracked those two issues, the software could have been developed further on a stable hardware platform.

    The lack of apps, poor battery life, heat production, and trouble with the voice activated features made me decide to resell it. Thankfully, I was able to recoup most of the cost when I sold it a year later.

    There seems to be steady interests in AR. Microsoft’s Hololens is neat, but it isn’t something that you can wear around all day. Apple’s upcoming Vision Pro looks cool, too, but it will be something aimed for specific use cases and not be a wearable augmentation to our daily, digital interaction with the world like Glass. Snap’s next generation of Spectacles seems like a high-tech version of Glass with full vision overlay, but it might be too opaque for all day and indoor use. Will something else come along to fulfill the promise of Glass?

  • Virtual Reality is Trying VR Again and Again

    Over the years, I’ve tried as best as I could to get interested in virtual reality (VR). The idea of VR excites me to no end. However, the reality of VR so far continues to underwhelm and frustrate me. The two biggest concerns that I have had are with eye fatigue, user interface design, and poor tracking and interaction with virtual environments. Below are some of the hits and misses that I’ve had experience with in commercial VR.

    2009: VFX1 Headgear

    The VFX1 Headgear was a bittersweet discovery. When I was much younger, I lusted over it when I saw it advertised in computer magazines in the mid-1990s. Unfortunately, it was priced out of my league and I didn’t know anyone who could afford one either.

    Fast-forward to my being a grad student at Kent State. One late afternoon as I was leaving the Satterfield Building–home of the English Department–I glanced at the recycling bins under the stairway by the exit and I saw a really big box emblazoned with the VFX1 Headgear on the side. Curious and expecting to find an empty box, I was shocked when I picked up the box and felt its weight. I opened it and discovered the headset inside. I brought it home and found the headset, cables, and manual, but there was no software or controller card. I was never able to find out who had thrown out the VFX1. I had hoped that I could find the person and see if they might still have that controller card in their computer, but I had no luck. I also tried to find the controller card through other venues–Craigslist, eBay, talking with vintage computer collectors–but I always struck out. I ended up selling it before we moved to Atlanta. Had I got it working, it would have not been an HD VR experience, but I had hoped to experience what it had been like when it launched.

    2015: Cardboard VR

    These Google-designed cardboard VR headsets are my favorites of all VR considering the simplicity of their setup and operation as well as cost. Also, they enabled me to easily introduce VR to my students–whether we used my phone or theirs. It just worked and gave immersive visual-focused with some sound experiences. I was let down when their development stopped.

    2017: Oculus Rift CV1

    Best Buy ran a sale on the Oculus Rift CV1, so I decided to give more substantive and immersive VR a try. In this particular configuration, I had an NVIDIA GTX 1060 6GB video card running the Oculus Rift. I was never able to get the focus 100% for my eyes and my small apartment’s limited space didn’t give me a lot of room to work in. Also, I had some real problems with interacting with environments and objects in games. Despite what changes I made to the Constellation tracking units, there were gaps between what I tried to do and what the software/hardware thought that I was doing. I ended up selling the set on eBay where I was able to recoup the cost.

    2019-2020: HP Windows Mixed Reality Headset

    When the local Microcenter had a stack of HP Windows Mixed Reality Headset and Controller Sets on sale for the bargain basement price of $129.99, I immediately bought one thinking that it couldn’t hurt to try this higher resolution than the Oculus Rift CV1 set at such a low price and I could resell it on eBay for more than I paid for it if it doesn’t work out. I am happy to report that I was able to get better visual acuity with the HP headset than the Oculus. However, it’s inside-out tracking presented the same kind of problems that the Oculus’ opposite style tracking had when it came to my interacting with virtual environments and objects. The frustrations of reaching not far enough or too far repeatedly was eventually too much. I boxed it back up and put it for sale on eBay.

    Future VR?

    I would like to try VR again in the future, but it might have to wait until I can move out of NYC. There just isn’t enough space in the apartments that I can afford for two people and a cat to comfortably coexist in a space large enough to accommodate movement-in-space VR. Of course, playing shooters or simulators in which I sit down while peering around with the headset on would be fine (analogous to the VFX1), but I would like to experience VR beyond that and interact within space. In the meantime, I’ll keep following VR developments until I can try again.
