Thanks!
I'm in the midst of writing a J1 emulator so that I can better debug all of the
forth code I've been writing. Looks like it'll be sometime this summer by the
time I can get a prototype built. :-(
UNIBUS RAM cards? Neato-keeno!! When will they be
available, and how do I
order some? :-)
I think Guy's MEM11 is going to be way cooler. I made my board in 2012
to scratch my own itch (but then didn't get it running in time and had to
spend real money on an MS11LD after all), and it's a memory-only device so
it plugs into the A/B positions of a MUD/SPC slot, which makes it useless
on an 11/20 which doesn't have those (right? unless you add a BA11K?),
and can't emulate anything that does DMA or interrupts (but that still
leaves a few things).
I'll be doing a new rev one of these months (to incorporate ECOs and
battery holders and add more devices, now that I did the CRC emulation for
E11 anyway) and then I'll certainly make them available, but not seriously
expecting anyone to order one. Guy's MEM11 is nicer!
Anyway here's a picture of Rev A:

Cool looking little board!
