I have personally seen in my professional work how some people are more likely to create a static charge. I don't know if it's clothes, physical chemistry or personality but there is a definite difference.
Before you work on that COSMAC Microkit, you better touch wood and metal!
Josh, Unless you have a DC feed from the power co., you are not getting any new electrons , only the same ones jogged back and forth.

You might, however, be sharing some with your neighbors who are on the same transformer. It might be worthwhile to invest in a whole house isolation transformer to assure that you don’t get defective electrons from your neighbors. Can’t be too careful these days.Duane

lol. On this note, I think the electric company may be giving us used electrons (and charging us for new ones). I have no way to verify this, does anyone here have an electron microscope?

When I found a "switch" inside that I flipped, it stopped killing drivers.
So in my case you could say the 1488/1489 drivers were not victims of normal circumstances, but of a short or mis-wiring.
In the end no biggie. I have a bunch of NOS drivers for my 3P+S, it's just my sio-A MITS serial card I'm won't risk on an unknown terminal.

The PC Museum here in Ontario has an IMSAI 8080 that I plan to get operational next weekend. It doesn t have the original 8080 board and without it the frontMessage 4 of 22 , Apr 7View SourceThe PC Museum here in Ontario has an IMSAI 8080 that I plan to get operational next weekend. It doesn't have the original 8080 board and without it the front panel can't work, so I've built a replacement 8080A cpu card and loaded it with RAM, I/O, and a Disk Emulator.
Does anyone have any CP/M software I can run on it for a decent demo? Wumpus perhaps?
