"Asking for a friend"...
Anyone have a spare MK11 box controller? At LSSM, we're bringing up an
11/70 and we need a box controller for the new memory.
If not, we'll get by, but just in case someone has one propping a door
I have a 150cc scooter with a LiteOn MC21 fuel injection ECU that is
malfunctioning. My search for a replacement brain has been unsuccessful.
LiteOn became Delphi which is now part of Borg Warner and I don't see
anything for download (or even purchase).
All I've been able to find online is the "Delphi Small Engine Management
System Service Manual" from 2008, which refers to an apparently
Windows-based program referred to only as "DIAG TOOL". It can display
running engine parameters and malfunction codes, although it does not
appear to be capable of reflashing the ECU.
I'm waiting for a connector kit to come from Amazon (probably via China)
so I can rig it up on the bench with simulated inputs. The unit is
potted in silicone rubber which will be a PITA to remove. I found this
Ukranian site where a member had the fuel injector driver transistor
fail (in his case, shorted) -
If that's my problem it's failed open, but I'm not going to mutilate the
box until I get it powered up on the bench...
Any help with anything relating to the MC21 EFI would be greatly
I have another odd preliminary document: Guide to writing a P/OS I/O
Driver and advanced programming notes. Order AA-BT73A-TH
Is there a copy on the net somewhere, or is this another unique oddball
I should scan?

I also started with ProComm Plus for DOS. Just like WordPerfect of the
time (5.x) I sure had all of those key sequences memorized....
I think I still have a copy on my old DOS workstation that I used to use.
Need to fire that up this winter.

Thank you for this tip. I had an old IBM NetVista all-in-one workstation
that I wanted to resurrect, finally did so within the last month (running
eComStation!) , and of course needed a way to connect to other things on
the network here. A terminal emulator is a must. :)
Installed ZOC, and now replying to this message connected to my Alpha in
the house. (the NetVista workstation is in the back garage....because who
doesn't need a workstation in the garage just in case?)
Now I need to see if I can find a halfway usable web browser...
you're invited to the Update computer club public lecture series
When: 2021-10-09, 18:00 CEST (Note: one hour earlier than usual!)
Update Computer Club: History and Not-So-Certain Future
At Swedish universities, students organize in clubs for spare time
activities like photography, sports, music and also computers! Update is
the student computer club loosely connected to Uppsala University. We
started out in 1983 around what was then new shiny computers and have
evolved into a caretaker of the old and precious. We have kept the very
DECSYSTEM 2060 around which the club was formed as well as a VAX 8650,
PDP-12, a running PDP-11/70 and many other things. The club is creeping
up on its 40th birthday and we would like to present a retrospective
with anecdotes and trivia. The future is uncertain as the university
department paying for our rooms is moving and will no longer be able to
accomodate Update. What will the next chapter for this old club be? And
how can you help us?
Pontus Pihlgren (Update)
The lecture is free and open to everyone.
Note: This talk is a contribution to the Vintage Computing Festival
Berlin 2021 and therefore happens one hour earlier than our usual time.
The link for participation is also different.

I doubt you'll be able to use anything other than a RD51 drive - as
this ancient V7M doesn't yet support newer drive types. You might
be able to put some of the system files on an RL02 - but I haven't confirmed
there's a RL02 boot loader on this kit.
Back in 1983 the PDP-11/23-PLUS was a relatively *new* machine. There's
later versions of Ultrix-11 (V2 and later) that added support for the 11/73
and bigger drives - look on the Unix Heritage Society site under Unix
Archive. There's a downloadable installation tape for Ultrix-11 there.

I am hoping someone here knows Richard Cornwell, driving force behind
KL10B SimH and associated forks.
Not sure how to raise the issue of simulated RP07 drives size not
matching RPO7 and looking like RPO6.
Also trying to figure out how to set switches as in other KA/KL sims.
I can't seem to find a means of doing that in RC's KL.
Is there a usage template? I have found the docs that describe it and
tte config but the questions above are not evident in my reading, does
not mean the data is not there, just I have not found the clue path.
thanks for any help or pointers!
