Thank you for the heads-up!

Unfortunately I'm a little stuck at the moment, especially as one of my
main MIPS machines (a 5Kc Malta system) died mid-May while operating. It
seems to be a faulty CPU core card and the base board may be fine, though
I cannot know for sure as I only have one each and I don't have a logic
analyser or at least a JTAG probe to peek at the system and see what's
going on inside.

If anyone knows a source of a replacement Malta, preferably with a 5Kc
CoreLV CPU module or another 64-bit hard core card (a number of different
ones have been made), then I'll appreciate if you let me know. I feel
rather depressed knowing that many if not most hit the scrapper already
while they could still find a good use. Somehow it is easier to get way
more obsolete hardware from 1980/90s just because it was general purpose
rather than niche.

Otherwise I'll try to get back to this stuff later in the year with
whatever I have that still runs, but don't hold your breath. Sorry!
