The B198, B199, and B250 modules of the KA10 use ICs. First customer
shipments are claimed to have been in late 1967.

They use the same R and S numbers, just late revision suffices. I have
a machine made with them that sometimes even works. I have a bunch
that have had the gold fingers peeled off (don't blame me - I got them
this way).

I didn't know we had this example in the collection, they were
hybrids like IBM SLDs
Do you know of any module part numbers that used them?

I think the W706 and W707 predated the M series by a hair, using
commercial MRTL (I think). These were the early TTY
receiver/transmitter cards.

Yes, but if you look at the picture/manual (I found a "Module location for
I/O" chart on pg. 335 of the PDP-7 Maint Manual - alas, not the whole
machine, just the FLIP CHIP part), the PDP-7 is all B-series and

After groveling through the 'PDP-7 Maintainence Manual' (F-77A), this seems to
be accurate. In "Module Identification" (pg. 6-5), it refers

Do you know or just guessing? Why would it be some kind of test gear with a
AR, MQ, and MB
There is an auction for some kind of early DEC module. It appears to be a
bit slice of MB, AR and MQ. There is also a signature by Gordon Bell on the
board.
But I cannot figure out which early machine it comes from.
