It's one EPROM, number 23-261E6. It's a 27C256.
Still on the subject of DEC ROMs, as some list members know, I keep images
of the ones from boards I have, "just in case", and I have a puzzle. What
are 23-398E4 and 23-399E4 from? And another: what ROM goes with 23-116E5
to make the pair?
And for the sake of completeness (of a sort) here's a list of ROMs (images)
I'm looking for:
23-031E2 VT100 terminal ROM
23-051L1 TQK50 Rev.D1 E3 ROM
23-094E2 VT100 extra chargen
23-095E2 VT100 extra chargen
23-096E2 VT100 extra chargen
23-097E2 VT132 extra chargen
23-098E2 VT132 extra chargen
23-116E5 KDJ-11B (PDP11/73+) boot Version 7
23-116E5 KDJ-11B (PDP11/73+) boot Version 7
[one of the last two lines is obviously a misprint, see above]
