Oooh, that's very interesting, and illuminative. The ROM isn't working (so
there's no way for the software console to work - its code is in that ROM).
So look at Section 1.5 of the Technical Manual
http://bitsavers.org/pdf/dec/unibus/M9312_TechRef.pdf
and make sure all the jumpers on the M9312 are as required. In particular,
jumper W-8 should be _out_.
If it's not, that would explain why the ROM at 765000 isn't resonding. If it's
in, that M9312 board probably has a problem.
Also, while we're at it, it's probably worth making sure the CPU will
run. Do this:
CLR
LAD
777 (This is a 'branch .' instruction)
DEP
EXAM (Should display '777')
CLR (I think you can dispense with these
LAD two, but just to be safe...)
CTRL-START
'Run' light should come on
CTRL-HALT
'Run' light should go out, should display '0' (or maybe '2', I forget)

I would leave them all disconnected for the moment; you don't need them. One
is the 'boot' switch on the console, and its ground. The other is the 'boot on
power on enable' (a duplicate of S1-2), and its ground. Since we're trying to
manually start the ROM console from the front console, they aren't needed for
that.
I don't recall offhand which one connects to which - I will have to check.

Not sure it will harm anything if you connect things wrongly, but that's
not tested.

Maybe some others, never get anything to the screen.
I have some cards that are marked TP1:Red TP2:Blk TP4:Clr
and other cards marked TP1:Red TP2:Clr TP4:Blk
I would really like to hear from someone that has it working rather than
risking popping something.

I am back in front of the machine:
The M7856 is set thusly:
??? 1? 2? 3? 4? 5? 6? 7? 8? 9 10

S5 DN DN DN UP DN DN UP DN DN UP
S3 DN DN UP DN UP UP DN UP DN UP

S2 DN DN UP DN DN UP DN DN -- --
The M9312 is set thusly:
??? 1? 2? 3? 4? 5? 6? 7? 8? 9 10
-- -- -- -- -- -- -- -- -- -- --
S1 UP UP DN DN DN DN UP DN DN DN
This should be 300, 8, Odd, 1
I have what I think is null modem between the M7856 cable and a PC
running XP with Hyperterm set to 300, 8,O,1
Troubleshooting from the programmers console:
CNTRL plus HALT, no bus hang.
CLR, 777566, LAD, 101, DEP, Hyperterm shows: A
CLR, 777566, LAD, 102, DEP, Hyperterm shows: AB (the B popped up next to
the previous A )
CLR, 777564, LAD, EXAM, display shows: 000200
CLR, 773024, LAD, EXAM, display shows: 165024
CLR, 773024, LAD, EXAM, display shows: 165024
CLR, 773000, LAD, CNTRL plus START, console says: 173002
I am thinking that the Hyperterm should be seeing an "@" and I should be
able to boot from there.
Any thoughts?

This one has me scratching my head.
eBay Item 302562153660
Sure, it's a Kennedy 9832 drive mounted in some sort of giant hard case.
Anyone know if this was a modified drive? What on earth would it be
used for?

Good, the console is working.

OK, that loads a '0' (halt) in 0.
> CNTRL+INIT

OK, so it reads the HALT at 0 and stops.
> CNTRL+BOOT -> Run light is on, SR Disp light is on
> CNTRL+HLT reads 173150
Sounds like it may be looping in the high bank of ROM? That's not necessarily
wrong.
I finally figured out what the ROMs in the M9312 do; the ROMs at 765000 are
the first-level diagnostic, and the console. The bootstrap code for the
various devices is at 773000.
> 773024 LAD, 773000 DEP, BUS ERR light comes on.
That makes sense; you can't write to the ROM.
> Any suggestions?
i) Check the ROM contents; there are two kinds of M9312 console ROMs, one for
most CPUs, and one for the 11/60 and 11/70, see the tech manual for the
M9312.
So read out the first couple of words:
CLR
765000
LAD
EXAM
EXAM
etc
and let's see what they read.
ii) Try starting the console code directly:
CLR
765020
LAD
CNTRL+START

Can't hurt.

All ?
??????????????? I can?t remember who contacted me originally about potential enhancements to the APE (Altair Peripheral Emulator) that I have mirrored at ape.classiccmp.net.
I heard from Frank Barberis and he mentioned that he?d be willing to make enhancements to the software if there was sufficient interest.
??????????????? So, if we can put together a list of desire enhancement/features I can try to get the ball rolling. Feel free to contact me off-list with ideas. Thanks!

Hello!
I am about to start with the project to archive disks from the Incoterm
system.
This system makes use of the Memorex 651 drive which is somewhat odd. It
has 64 tracks,is hard sectored with 32 sectors and spins at 375 rpm.
But I do have the drive which hopefully still is working. However the
interface connector is nothing like I seen on a floppy drive before.
https://i.imgur.com/TklddLP.jpg
It is a AMP 202515-1 housing. The mating 202516-1 which I need is still in
production and available for purchase from Mouser. The small coaxial
connectors on the other hand has a minimum order of 1000 units and costs 10
euros each...
https://www.mouser.se/ProductDetail/TE-Connectivity/201146-2/?qs=DuOyNqEZh0…
Does anyone know of a source selling something like three coaxial
connectors like this at decent price?
Or maybe a suggestion for another connector that could be modified into fit
somehow? Potentially using glue to fixate it.
Of course the last resort is to just solder some wires directly onto the
drive PCB, but if there is a nice solution I try that first.
> From: John Welch

Concur 100% with Henk's comments.
There is a manual online for the M9312:
http://bitsavers.org/pdf/dec/unibus/M9312_TechRef.pdf
which will tell you what the other start options are (Appendix C), but see
page 3-1, too. Note especially the bit about how the primary dianostics
are run before it starts the console emulator; I forget what it does if
the primary fails, possibly it halts?

Hello All,
I am looking for a copy of:
Troubleshooting LAN Manager 2 PDF by Michael
Publication date: 10/01/1993
ISBN:155851161X
ISBN13: 9781558511613
I've looked the usual areas and can't find a reasonably priced copy. There
was one on epay for $10 but the day I marked it to watch suddenly it was no
longer available. Interestingly enough the seller has an exact copy w/ the
same description/condition relisted for $67 now...
Alternatively if anyone has a copy of LAN Manager 2 OS (not just the
workstation 3 disk set) w/ manuals that they no longer want I would be happy
to take it off of your hands. Thanks
Thanks in advance
-Ali
