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) - http://geon-club.com.ua/forum/viewtopic.php?f=35&t=5735 <http://geon-club.com.ua/forum/viewtopic.php?f=35&t=5735> 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 appreciated. Thanks!

Of course I was using it mainly to dial BBSes 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. > With windows I actually started using ZOC which seemed to run better and 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... Fred

Lecture: Update Computer Club: History and Not-So-Certain Future, 2021-10-09, 18:00

by stueberahoo＠yahoo.de

Hi all, you're invited to the Update computer club[0] public lecture series "Updateringar"[1]! When: 2021-10-09, 18:00 CEST (Note: one hour earlier than usual!) Stream: https://streaming.media.ccc.de/vcfb2021/ Q&A: https://bbb.vcfb.de/b/ank-eka-1zw-rkc 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.

PDP-11 Unix V7M-11 V1.0 under SIMH

by tony.nicholson＠computer.org

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. https://www.tuhs.org Tony -- Tony Nicholson <tony.nicholson at computer.org>

Shiner ESB Apple Network Server prototype

by spectre＠floodgap.com

Finally took some pictures of the (sadly non-working) Apple Network Server prototype I landed and also got around to analysing the hard disk it came with. Spoiler alert: this Shiner HE was at Netscape doing "real work" for several years at least. https://oldvcr.blogspot.com/2021/10/shiner-esb-apple-network-server.html http://www.floodgap.com/retrobits/ans/esb/ -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- A kindness done today is the surest way to a brighter tomorrow. -- Anonymous

SIMH KL10 usage guide? Hints? and

by bobsmithofd＠gmail.com

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! bad bob

Found my favorite DOS editor

by van.snyder＠sbcglobal.net

I found files for my favorite DOS editor on an archive from my OS/2 machine, which replaced my DOS machine in about 1990. The editor was ETOOL, from Amerisoft. If anybody wants the files, I'm happy to send them. -rw-r--r-- 1 vsnyder staff 245248 Mar 8 1988 e/dos/etool.exe -rw-r--r-- 1 vsnyder staff 1024 Mar 8 1988 e/dos/etool.fig -rw-r--r-- 1 vsnyder staff 83968 Jul 9 1985 e/dos/etool.hlp I lost the manual decades ago.

PDP-11 Unix V7M-11 V1.0 under SIMH

by tony.nicholson＠computer.org

Recently Al Kossow made available a zip file containing a Micro/PDP-11 installation kit for Unix V7M-11 V1.0 on bitsavers as RX50 disk images. Tinkering away here in Covid lockdown, I've managed to get this running under SIMH pdp11 emulating an almost historically accurate PDP-11/23 plus. I've placed the SIMH initialisation file, a couple of RD51 disk images and an "installation recipe" for making these disks on GitHub at - https://github.com/agn453/V7M-11 While I mainly had exposure to later versions of Unix and Ultrix-11 on a PDP-11/70 as an undergraduate - this one surely brings back memories!
