I found an old 6100/66 with a DOS card waiting to go to auction at my work. I plugged it in and it worked fine so I let my co-worker take it home. It has a working monitor with the old Apple proprietary plug along with an adapter to plug into the DOS card. It all works, but it is still loaded with 7.1 and a bunch of old software.
I want to update it, but I don't know how far I can go (OS wise) before everything really starts to get bogged down. I don't know how much RAM it has but I intend to find out soon. My options at this point are 7.6, 8.6, 9.0 and 9.1. I think that 9.0 and 9.1 are out, so I guess my question is how fast is 8.6 on a 66 MHz 601 (and with how much RAM)? If it's dog-slow, I'll load 7.6 and the newer versions of the apps separately or add RAM as needed. Any feedback is more than appreciated.
