Prime Reverse-Engineering

[Hooloovoo]

Cemetech user Val and I have been doing Prime reverse engineering. So far, we have identified the JTAG pins (we hope), and Val has a JTAG adapter soldered onto these pins on a boot-code-screwed calc. Unfortunately I lost my calculator (in space), so all of the reverse-engineering is being done on two of Val's broken Primes, one of which had its CPU removed so traces could be, well, traced. Val has soldered on a jtag adapter and we hope to find out more, and possibly use the JTAG for other things like debugging the Prime OS.

The JTAG was mentioned in this Omnimaga topic, which implies that there is a way to fix the calculator.

All of the info is contained within several posts at http://www.cemetech.net/forum/viewtopic.php?p=230621.
