Eh, de nada. But thank you.

OK, so the situation here is pretty complicated. To start with / make things
worse, that CPU uses lots of PROMs. Lots and lots and lots and lots of PROMs.
For the data paths board (M7260), both major versions appear to contain the
same PROMs (going by the DEC part numbers), but the chip location (Exx)
numbers are all different.
For the control board (M7261), the C, E ('early' version) and F ('late'
version) etch revisions each contain mostly the same PROMs, but apparently
with slight differences between the sets of PROMs in each (as reflected in
different DEC part numbers). For details see:
http://gunkies.org/wiki/PDP-11/05#Control_PROMs
to which I have just added all the gory details.
As to getting the contents of all of them dumped in machine-readable form -
oi vey!
>> on the earlier version (prints for that version are in the GT40 prints
>> online
It turns out that I have hard-copy prints for the "C" etch revision of the
M7261, which do not yet appear to be online; the GT40 prints have the "E"
etch revision.
I will scan the pages for that revision of the board, and put them up 'soon'.
(I'm not doing the whole print set, it's about 1" thick, and most of them are
for other things anyway, like MM11-L memory, etc.)

Hi, I borrowed a DEC inlay from someone (a KA10 CPU bay) and scanned a chunk
of it (as much as I could fit into my A4 scanner :-) at 200 dpi:
http://ana-3.lcs.mit.edu/~jnc/tech/jpg/KACPUPanel.jpg
I have a TC08 inlay, but it's currently being used in my QSIC display (until
we can get the RKV11-F/RPV11-D inlay done :-), and I didn't want to yank it
out. As far as I can tell, it's the same font on the two of them.
> the closest I know of off the top of my head is Akzidenz Grotesk.
The Akzidenz Grotesk Medium is indeed very, very close (other than the zero).
Do you happen to know if that font available for use in non-commercial
settings?
Thanks!

Manx lists MP-01394-00 as the Field Maintenance Print Set for the DEC
Professional 350. I can't find this online and I was wondering if anyone has
a scan of it by any chance?
Thanks

Since a few days, my EXORciser Development System is finally able to boot from floppy diskettes.
Previous attempts have shown that the Motorola EXORciser M68SFDC1 floppy disk board used has a special modified ROM version. This was probably written for an 8-inch drive, in which the Write protect and Direction signal were inverted.
For the sake of simplicity, I have used free inverter on the board to invert the signals accordingly.
After adjusting the PLL frequency, reads and writes from the card are now error-free. And all without FDC, only clever programming by Motorola software engineers in the early 76?
Originally, the EXORdisk system was a dual drive with two 8 "units. This I have replaced with a double drive of two 5.25 inch units. An Epson and a TEAC, which can be jumpered to 360 rpm. Luckily, 2HD floppy disks are easy to R&W.
I also got a GOTEK floppy emulator running, which I can boot from. Thanks to Roland Huisman, Bitsaver has some interesting floppy disks that convert to HFE format work perfectly. This format makes the Gotek drive most reliable.
Now to my question. The vintage computer forum at http://www.vcfed.org/forum/archive/index.php/t-44638.html mentioned some interesting manuals. Archive.org has some manuals, Bitsaver does not have manuals about the M6800 development system.
If someone already owns scanned manuals to the following list
M6800 Basic Interpreter Reference Manual
M6800 Macro Assembler reference Manual
M68SFDU Exordisk 11/111 Disk `Drive Unit Maintenance Manual
M6800 Exorciser 11 User's Guide
M6800 Exorciser User's Guide
MEX68PP1 PROM Programmer Module Supplement M6800 Exorciser User's Guide
I would welcome any feedback or questions

Greetings,
I'm trying to find a way to get my DEC Rainbow's monochrome output onto a
newer monitor than my aging VR201 (especially since I zapped something in
it and my diagnostic efforts to date haven't fixed it).
So, I found the bit in the Rainbow docs that said the output was DC Coupled
RS-170 signals and to convert to RS-170 (NTSC black and white) I needed to
put a 10uF cap inline to make it RS-170. So I did this, and fed it into a
generic NTSC composite video to VGA thing, and got only a little joy. The
first few lines seem to be missing, then the next few are OK and then
nothing else.
I tried to google this, but found nothing. My google foo has failed me.
Does anybody else have a working setup?

Hey Everyone,
I just thought I'd share a video of how I'm going about troubleshooting the
bad DRAMs on my MS650 memory board.
https://youtu.be/eDMhdAEFEgc
I apologize for the shaky-cam, I don't have a tripod, and I needed to do a
lot of panning anyway.
I will be sharing my notes on the MS650 once I have a chance to write them
up properly as well. I wasn't able to find a printset for the RAM card
itself, so I assume one doesn't exist in digital form yet. I have
documented what bit and memory range each DRAM on the card corresponds to,
which may help someone troubleshooting in the future
Regards,
Joe Zatarski
