*actually* -- the dual microm simply combines the 3007 and 3010
microm chips into one dual carrier, which frees up a slot for
the EIS/FIS chip... you still need the EIS/FIS chip, however.
I've got a couple of PDT-11/150s with the mod. There was a version
of space invaders for a VT100 on RT-11 which required EIS/FIS for
some reason. For quite a while we used the EIS/FIS emulator
driver (I think it was from Ian Hammond), at least until we found
a supply for dual microms and EIS/FIS chips.
(This was back in the days when the PDT-11/150 was sold to DEC
employees and we had a broad-spectrum mailing list to discuss
it -- I was a moderator for it)
