Digital Archaeology – Expedition #5 – iMac G3 266 (Tangerine)

in retrocomputing •  4 months ago 

This expedition took me out into the wilds of a community garage sale. It was, in fact, my own community and this is an event in which multiple households sell arcane artifacts of often dubious value out of their garage, or more often, their driveway or yard. As I picked through the corpses of a couple of CRT televisions at one such establishment, I discovered a tangerine colored curiosity that looked much like one of the above mentioned televisions but was actually something more. I asked the proprietor if it was in working condition and received an acknowledgement that it was in fact fully operational. At an asking price of $5 I did not even attempt to bargain lower. I grabbed it and awkwardly trudged a quarter of a mile back home with the iMac (including keyboard and mouse) that I had just discovered (along with my bike). If nothing else, the weight promised something substantial...

I knew I was dealing with an iMac with a PowerPC processor that was >= 10 years old but I was not terribly familiar with the various models that were available. Despite assurances, I was not even really certain that it would really work. It was no SX-64 or Commodore 65 prototype but it was in good physical condition and for $5 it seemed like a pretty good find. As soon as I arrived home I took it inside, plugged in in and pressed the power button to see what would happen...

To my slight surprise it booted right up. It was running OS 8.5 and had a whopping 32 MB of RAM. After a little poking around I figured out it was an iMac 266 MHz G3 (Rev. C). Here are the stats from EveryMac:
