Mike's PCjr Page

Thanks! Once I got the power issues sorted out with my DOM, the debug script worked great!

I'll have to get a patched DOS to use then, because both versions I have on floppy don't allow me to do anything to those partitions. Guess I'll try that tomorrow.

I got a used 1GB DOM on eBay, made by Silicon Systems apparently. The jr-IDE can't detect the DOM all the time so I assume I'll need to find something else, but when it does detect it, it shows 4 non-DOS partitions (according to DOS 2.10 and 3.10) and I can't format the drive or delete any partition...

I have one joystick, so I'm not sure if I can access the test mode. What exactly do I need to accomplish this?

Nope, just the ERROR A. But now whenever I have it attached, it doesn't seem to detect it or test for the expanded RAM anymore, so either the connector has been damaged or something else has gone kaput.

Anyone here have much experience with the Quadram expansions? My RAM expansion (I think it went up to 256K) went bad sometime in the mid 90s and for the longest time I didn't know what "ERROR A" meant so I carried on with life until a few years ago and found out that it was a RAM issue. Re...

I would also be very interested in picking one up.

Hi!
The PCjr was the first computer I had back in about 1992 or so and I'm trying to get it fully functioning again! Glad to know this place is here.
