Second Donation to Georgia Tech Library Archive’s Retrocomputing Lab: Power Macintosh 8500

When I met with Georgia Tech Library Archives’ Department Head Jody Lloyd Thompson and Digital Collections Archivist Wendy Hagenmaier to donate three vintage computers (a Dell Dimension 4100, Apple Performa 550, and Apple iMac) and other computing hardware a week and a half ago, I noticed that they had room for one more computer, so I pitched them the idea of my making another donation to fill the gap between the Performa 550’s 68030 processor and the iMac’s G3 processor:  an Apple Power Macintosh 8500/120. They agreed to accept, so I set about preparing the computer for them.

My Power Macintosh 8500 was in very good shape, but like many vintage computers with persistent clocks, it needed a new lithium battery.

To replace the Power Macintosh 8500's on-board battery (upper left corner of photo), you have to remove the motherboard.

I replaced the battery, installed Mac OS 7.5.5, a number of different software titles (including Apple’s Plaintalk Speech Recognition–I threw in a Plaintalk powered microphone, Project X/Hot Sauce, and Cyberdog). I discovered that the plastic inside the case did not age well. The PowerMac 8500 has a lot of plastic components that are held together with flexible tabs or clips. When I applied a small amoung of pressure on the tip of these clips to release them, most of them would break. Luckily, the case ties together very well, so I only had to piece some parts back together with clear tape (the power button/light assembly) and metal duct tape (one drive plate cover on the front of the case). To help dissipate heat, I  added a rear slot fan made by Antec.

I made a video demoing the finalized system, which I’m including embedded below (I apologize for the flicker, but my digital camera doesn’t have enough adjustment features to match the refresh rate on the Apple 14″ Color Display).

In addition to the Power Macintosh 8500, I gave the Archives a box full of software and late-1990s/early-2000s video games for Macintosh. These might help facilitate more connections around campus (Computer Science, Media Studies, and Game Studies).

As I’m leaving soon for City Tech, I believe that we can do more together in our work with vintage computing. I floated the idea of a symposium, conference, or some other kind of connected project. Also, from what little I have learned so far, there’s a lot of investment and interest in computer technology in NYC (and Brooklyn in particular). I am looking forward to making new connections with others studying retrocomputing and New Media. I know that many opportunities await.
