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)

> From: Chris Zach > Might have an older MXV11 as well, could the 18 bit one do this Ooh, good catch; yes, the MXV11-A also has an LTC. I too have an 'extra' one. The OP should probably check to see if his P/S generates the bus clock signal; most of the options we've discussed for him

I most probably have a BDV11 bootstrap module I can part with. Might have an older MXV11 as well, could the 18 bit one do this (I think it did, and I'm guessing you have a pdp11/03 with a quad width CPU) CZ On 10/3/2020 9:19 PM, Chris Hanson via cctalk wrote: My little LSI-11 system doesn't

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 but I haven't confirmed that, so my preference would be an M7195 if possible. Does
