You have an 820-II; the original 820 only has two ROMs (U63, U64).

Hi,
I'm not prepared to lay out $200 for these Xerox ROMs, but if I do manage
to get them, I'll read and share them. I did not know there were 5.0 ROMs
for the 820-II, but it appears there were, and they are included.

Rod, others,
I have so far been unsuccessful getting my CQD220A for SCSI HD, and RQDX3 for
floppy to coexist in an 11/83, at least with bsd2.11. I am eager to hear
whether you get both controllers working in the same box, and how.

David,
This might seem stupid, but I recently had peculiar results with a usb-powered
programmer failing on certain ranges of addresses on certain chips, that turned
out to be inadequate current available on my USB port. For me, a high-current
powered USB hub solved it. I programmed a huge numb

Hi,
I am working on several projects requiring 2708 and 2716 EPROMs, and
am finding some of my chips will not erase, and some will not take
a program. I've also learned more in the past week than I wanted
to know about repairing Data-I/O 29a/b programmers.
I vaguely remember in the 1990s baking

Hi,
I picked up an empty 4x8 Q-bus chassis at VCF-East this year. It's
labelled "USDC CSS-823 Processor System" on the outside. It's not a DEC
backplane, but the chassis is light aluminum, smaller and in some ways
nicer than my pile of BA23s. It includes a switching power supply,
LTC and q-bus
