Mike's PCjr Page

I just picked up (literally) a PCjr from a local original owner. It has a Racore Drive Two Plus DMA with the 512k memory board. I have all the receipts as well as correspondence with Mouse systems and Racore. A boxed Mouse Systems mouse and several original games are among the items included. There's even several items from Computer Reset with letters, catalogs and Richard Byron's original business card.

Does the Drive Two Plus require a boot disk? Does anyone know what options there could be inside to look for?

Nothing is needed for the 2nd floppy drive to work, but you will need jrconfig or some other PCjr memory driver to use more than 128K of RAM, something for the RTC in the tall sidecar (and probably a new coin cell battery as well) and the mouse.
