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.

Thanks to everyone who replied, on- and off-list! There?s an MXV11-B (M7195) on its way to
me. :)
Since people were asking about my setup, here?s what I have:
- MDB BA11-clone enclosure, PSU, and 8-slot 22-bit backplane
- DEC KDF11-A (M8186) rev C processor with FPP added
- DEC DLV11-J (M8043) SLU
- Motorola M1132 128KW RAM
And some stuff that?s untested but I?m eager to try:
- (soon) Emulex UC07 SCSI controller
- (soon) DEC MXV11-B (M7195) system controller
- DEC MSV11-LF (M8059) 64KW RAM
- DEC DEQNA (M7054) Ethernet controller
- DEC RLV12 (M8061) RL01/02 disk controller
- MDB MLSI-SCM11 system controller
For the latter two, I need to figure out whether my backplane supports ABCD use in the
first couple of slots, or if it?s purely an ABAB model. (The KDF11-A, RLV12, and
MLSI-SCM11 came in the backplane, but I?m hesitant to interpret that as ?these were
configured together in this pattern? rather than ?these happened to fit in here for
storage.?)
I?m actually still looking for docs on the MSLI-SCM11, since it looks extremely
configurable and I have no idea how to use it or what it?ll provide?
As for what I?m going to do with it, I?m thinking XINU. Comer?s book is one of the two
books via which I learned C (Tannenbaum?s was the other) so I think that?d be a fun system
to have up and running, especially since it has IP support.

I have an ~ 30 page manual for the MDB MLSI-BA11-600 series chassis, if there is something
that might be answered from that.

Photographed. No scanner.
It's not as good as 600dpi scan, but pretty good.
I'll send access url.
