Re: ADLIB/MPU-401 Expansion bay

I’m more interested in the MIDI out. If I could get MT-32, that would be really neat.

Re: ADLIB/MPU-401 Expansion bay

Was this ever actually made or just designed? I'm sure we could source the parts and I've got enough soldering equipment to put one together. If we had a printed board, we could make this work.

Get a jrIDE from a reputable seller, like TexElec. It adds 640k, an IDE connection for a hard drive, and a system timer. Worth every penny if you're into this stuff.

Mouse Systems Mouse

So through some creative buying and asking, I finally got a PCjr Mouse Systems optical mouse and mousepad.

It draws power from the light port and connects through the serial port. It's really kind of interesting how well it works for the era is came from.

Anyone else have this one?

Do you have any interest in selling the guts from that Racore expansion? I got a unit that had a good drive and some of the parts, but was missing the power supply.

Re: Parallel Port Side Car items

I finally modded mine for the up/down and attached a Zip drive to it. Works great, no issues.

I'd be interested in putting an LED. I've got a stack of them lying around from repairing a toy lightsaber.

Motherboard Failure

So I installed a V20, Tandy Mod, and a PC-Sprint on a cherry board I picked up from Computer Reset. It worked for about 10 minutes and crashed after I tried to run Civilization on it.

Re: NEC V20 Chip

I think I ordered the wrong V20 chip. There's 5 MHZ, 8, and 10. And I want the 10, correct?

Re: Keyboard problem

It's not an infared issue. It works flawlessly in all the native PCjr and many more of the other apps. I was playing a game that I wanted my daughter to try called Super Solvers: Treasure Mountain. It will run natively on PCjr, and will run TGA with a command line tag of -t. It just won't recognize ...
