If not, then one of the pins is probably +5V. It's old enough that I wouldn't assume it uses a C-64 supply or even the voltages for the C-64 (+5VDC, 9VAC), but it's worth looking at. Not me; sorry. Perhaps on funet? Worst case, you could write a quick BASIC program to try OPENing all the devices from 4 to 31 and see where it responds (once you get the power issue resolved). Without docs, it'll be hard to tell if there are any significant secondary addresses, though. As for special software, there should be at least a simple term program for it. It's possible to write one in BASIC - I did for the C-64 (with a VIC-MODEM). You'll have to do ASCII<->PETSCII conversion if you want to talk to a host expecting a VT100 or something similar. I used to use my simple term prog to talk to BBSes and CompuServe, c. 1982. It did everything I needed except download files (which wasn't how I was using the modem back in those days - I did mail, chat, online games, etc.) Again, check funet for anything related to the 8010. Nice find. I've never seen one. Good luck on the hunt for docs. -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 20-Oct-2004 18:40 Z South Pole Station PSC 468 Box 400 Temp -65.7 F (-54.3 C) Windchill -93.7 F (-69.8 C) APO AP 96598 Wind 6.7 kts Grid 068 Barometer 677.3 mb (10727. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html
