That’s really good of you to offer Sonny. Does the cable you have resemble the one in the picture I posted? I believe it’s what came with the Racore unit. Thanks so much for your response.

My Racore Drive 2 isn't working and I suspect I damaged the floppy cable. Can you confirm that the cable in your photo can be used to successfully connect Drive 1 to the disk drive adaptor without involving the Drive 2 unit? I'm asking because that's what I'm basing my conclusion about a faulty cabl...

I took a look at pictures that Jeff sent me and the expansion chassis is missing a row of RAM chips, which might be the reason why it is not counting the memory. (If the wrong row is populated DOS will see a hole in the memory and not count further.) The Racore can be configured with partial memory...

There is a pin that appears pushed in on the side of the jr that the Racore side unit fits into. However, that doesn't seem to get in the way of recog...

I have Version 4.0 of Microsoft Flight Simulator, whose requirements are stated as 384K RAM and a floppy disk drive. My PCjr came with 128K and I have two 128K sidecars. When I boot up, the count on the monitor does go up to 384K, but when I try to open FS, I get a message that the program is too la...

I've been trying to resurrect my PCjr that had the Racore unit in place. It's a long story, but I think I likely damaged the disk drive ribbon cable and am wondering if anyone knows of a place from which to obtain a replacement. When I boot up with all Racore connections intact, the monitor displays...
