My little LSI-11 system doesn't have a usable
Line-Time Clock because
it lacks the register, which it expects to be in either an MXV11-B
(M7195) or a BDV11 (M8012). My power supply theoretically supplies the
LTC .. so my preference would be an M7195 ...
Does anyone have one they'd be interested in parting with?
The MXV11-B is rare and expensive - I think because it's a Q22 card. The
BDV11 is, on the other hand, fairly common, not not too expensive. If you
can't find a reasonably-priced one (i.e. <US$50) one on eBait, Paul Anderson
used to have some. If he's out, I can probably be convinced to part with one.
The BDV11 has on Q18 _terminator_ functionality; there's an ECO to make that
Q22,though.
FWIW, both the KDF11-B and KDJ11-A have built in LTC's, if a CPU
upgrade is feasible for you.
