I hope to find someone in the VCF/Mid-Atlantic living close to me that could shed some light on what my problem might be. All the computer repair people think a S-100 bus is something you ride to work in the morning and raised an eyebrow at the mention of an 8" floppy disc. I didn't realize so much time has passed.
I live just north of Baltimore in Timonium Maryland only a few miles from I-83.
Please get in touch if you would want to lend a hand reviving my IMSAI.
I look forward to learning about the VCF/Mid-Atlantic and perhaps meeting some of the members. This is all new to me so i'll try not to embarrass myself by making stupid comments or something similar.
For many years I restored early Corvettes but have emptied my shop and now only make a few reproduction parts.
Please be in touch,
Fred Terry
Fred Too bad I missed you, I was at the in-laws who live in Timonium-Lutherville for Chirstmas. I have an IMSAI and a few Perci drives. I return to Timonium monthly, if you're still having issues I would be happy to at least help diagnose your problems if not help fix.
Persci drives' caps need to be replaced at this point. Every one I have seen.
I have my IMSAI 8080 set up on my workbench here at home but I live an hour 1/2 from you.
-- Bill Hi Bill, Thanks for the reply. I'm not as helpless as I first implied. I restored a few vintage pinballs after wading through their schematics. I have a full set of schematics for the Persci but no diagrams for the power supply. I think this is where my trouble could be. I have no 24v so the latching servos don't function. How do I tell if my capacitors are shot or do I just replace them? Would that restore my 24v? Let me know the next time you might be in the area. I can show you what I have and you will quickly see what is not working. Thanks, Fred T.
