Ooh, you tease! Any chance of that
document escaping altogether?
Assuming it's still there, and that you get Boundless
and/or COMPAQ (and/or HP if you don't get your
skates on ...) to OK it, then there should be no problem :-)
They are online, but the schematics don't list the
contents of the
ROM
I thought you had a VT52 - so just dump the ROM. Actually,
dump the ROM anyway - it must be past its sell-by date by now!
Of course, deliberate decisions are made about how
faithful a later
model would be when emulating an earlier one. After all, a VT220 in
VT100 mode doesn't emulate a VT100; it emulates a VT102 (or VT100
plus
Level 2 Editing Extension, if you like).
Yes - and I doubt that the VT52 emulator
makes *any* attempt at emulating the VT52
quirks. In fact, it's quite possible that noone
knew all the VT52 quirks and so the VSRM may
have required only adherence to the published
VT52 information (which admittedly may have
had internal-use-only enhancements).
When I wrote that VT102 emulator, way back
when, the customer for whom we were
implementing it had requested VT103 emulation
on the basis that it was a higher number
than VT102 and so must be better. I never
saw one in real life but the manual documented
it as a VT100 + LSI bus (no, I did not implement
the LSI bus ...). I suppose I should just
count myslef lucky that they didn't happen to
know about the VT105 or VT125 or VT131/VT132!
