IBM PCjr

Yeah, the plastic is fairly brittle at this age. I haven't taken my original one out of the case to replace a few old caps for that very reason. And unfortunately the plastic between the plugs is similar and bent pins are not uncommon. Be careful putting cables in and out and make sure you have them...

Nice! lol. I need time to pick up my guitar again.

Alright, so it does work! I reported that I was getting sector not found errors. Logging data via Flash Floppy didn't help me diagnose the issue, but I noticed that the unit was never leaving track offset 0. It would switch heads, but never go to track 1. i.e. display always shows T: 00.0 or 00.1. S...

Starting a new thread dedicated to this as it started under the 3Flop section. So, I've been attempting to get my Gotek to allow my PCjr to read high density disks through the PCjr flopper controller card. It is known that the PCjr controller is not happy with HD drives (bitrate too high at 500kbps ...

Compute had several books for the PC and also PCjr. Compute!'s IBM & Compatibles BASIC Program Collection Compute!'s First Book of IBM Compute!'s Second Book of IBM I thought I had more but don't see them at the moment. I learned to program by typing in tons of these programs when I was a kid :).

Nice! My memory is still fuzzy when my dad first brought home our jr. I seem to recall booting to BASIC, typing in a program out of a book and running it and having fun. Then wondering why "save" didn't work. It took me quite some time to type the program in and get it working and I couldn...

Certainly! I wasn't able to attach the images as attachments as even shrunk down it said they were too big. https://i.ibb.co/tpLbxCS/Microsolutions-Backpack-Floppy-on-system.jpg https://i.ibb.co/L5w29Tw/Top-view.jpg https://i.ibb.co/L9RDjF3/circuit-board-wire-in-place.jpg https://i.ibb.co/SRx4wv3/ci...

I saw this thread and it made me curious. Does anyone else have a Microsolutions 5 1/4" high density backpack floppy drive? I'm curious how many others had one of these. It appears the disk that mine came with labels it as version 2.01, November 27, 1991. Mine still works well although I don't ...

You saw that too? I saw that too and wondered. Especially since it looked like it was soldered in

I've got a jrATX with the 90W PicoATX power supply similar to yours and a jrIDE. I've run it with a parallel port sidecare and connected it to an expansion board which adds a 5 1/4" high density drive. And although I've never had your issue, I have had an odd issue where KQ1 fails to boot and r...

Anyone have a spare PCjr case laying around? I have a spare motherboard looking for a home .
