Anyone want to part with a DEC MXV11-B (M7195) and/or M8012 (BDV11)?

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

FWIW, both the KDF11-B and KDJ11-A have built in LTC's, if a CPU
upgrade is feasible for you.
