Think I've got it. The solution was in front of me the whole time. I had been using Shareway IP PERSONAL on my Color Classic so that it could serve to my iMac running 10.5. I never bothered to read about the more advanced versions you could buy from them. Turns out, if you have Shareway IP STANDARD, you can use the Mac running it as a gateway to bring a older Appleshare only Mac (or any Appleshare server like NT or Novell) across through TCP/IP. I will need to get a Plus/SE/Classic to test this. If that works, and I can track down the EasyShare software, then I'll invest in a working 512k and HD20 and give it a try!
