jr-IDE for PCjrs (Re: XT-IDE V2 PCBs)

I would like to point out that there is a jrIDE sidecar, which was originally derived from the XT-IDE work but is quite different now. Here are the main features: - fits inside of an existing PCjr sidecar shell - Adds 512KB of SRAM to fill the machine out to 640KB - Adds an IDE interface using an adapted XT-IDE BIOS - Real time clock (uses a command line utility at the moment) - POST display - The BIOS boots directly from the IDE drive - Implemented using CPLD to keep the chip count down - IDE registers are memory mapped - this sucker is fast! I originally grafted an XT-IDE onto a PCjr and modified (hacked up) an early version of the BIOS to work. That lead to ideas and discussion, and eventually the jr-IDE sidecar. Alan H ("eeguru") did the design and implementation work. I've done most of the BIOS work. Details, including how to get one can be found here: http://www.brutman.com/forums/viewtopic.php?f=1&t=180 The short story: Kits are $70, and you have to provide your own sidecar shell. We have a few happy people using them now. But it was a limited run of cards (20-25?) so they won't last forever. Mike
