I was able to get a Jr-IDE on the last batch that was listed on eBay and I just bought a IBM PC Jr Power Expansion Attachment (I have no idea what it does I only wanted the case). A friend got me a NOB IBM PC Jr Joystick,
So if anyone needs the guts of it let me know.
I am still on the lookout for a machine and monitor. I never owned one of these machine but I do remember selling the software and cartridges when I worked at Toys R Us in the 80's (well I say selling the software but no one ever bought it). Seems like a odd little machine that might be fun to play with.
