They seem to have broken it sufficiently now that nothing is returned after the end of October.
Is there anyone indexing Usenet that has a clue? It seems like all that is left is for-pay
services for searching alt.binaries.
Are there any AS/400 emulators out there?
Alternately, any baby AS/400 systems in the Columbus, OH area? I'm
asking for a friend.

I have had some progress in this matter:
I got a reply to the letter I sent to folks at tdsys.com. The gentleman had
forwarded to the designer of the Viking series of adapter boards and to the
lady that was working with configuration of products. He had not yet go a
reply from them.
I also checked how the address decoding PAL is connected and I now
understand that it has two outputs, connected to another PAL chip and then
16 inputs. These 16 inputs are the 4 jumpers and also BDAL02-BDAL12 and
also the BBS7 signal. Looks quite reasonable being an address decoding
chip. I more or less presume that the reason for two outputs is that one is
for disk and one is for tape. I have to verify that by reverse engineer the
actual content of the PAL using a small arduino board.
You mention that there is a special way of accessing the configuration
menu. It make sense since when I examine the board more carefully I
discover a small serial EEPROM that might be used for storing the
configuration. It would be really interesting to get more info about how to
access this secret menu! Anyone else out there that knows about this?
I have the cab kit for it. It has a DB25 connector as well as a 50 pin male
IDC connector. But there is also pads for a 10 pin connector that seems to
be for the second serial port. What is the use for this second serial port?
The board has a Signetics SCN2681 DUART chip so it definitely has two
serial ports.
Regarding versions of the firmware. My firmware is 4.0 :

Zane, Pontus: What is your version?

I found several spare switches and handles for what I believe would be a
PDP-11/10 or similar. The handles are white and are marked 1210785.
The switches are C&K 7121 (on-on) and 7128(on-momentary on).
Can anyone confirm?
Thanks,
Kyle
Seeing the discussions about the HP150 and the HP-IL stuff reminded me that I have an HP 150 with the 3COM Ethernet card, but I've never found any software for it. I checked hpmuseum.net and they don't have software, and didn't even have a picture of the card until I provided them some pictures of mine. Does anyone happen to have the software?
Hello ccmp'ers - July is almost here and that means it's time for me
to start making noise about our yearly Midwestern weekend-of-fun.
This year's Vintage Computer Festival Midwest will be held a bit
earlier than in previous years, owing to the usual scheduling
conflicts with holidays and other events. The weekend for 2014 is
September 13-14.
Those coming from out of town and staying over night should call the
hotel ASAP. Registration at the group rate has been open a few weeks
now but last I heard rooms are still available.
If you would like table space, please email me privately with your
requirements and what you'd like to display and or sell. Most of the
provided tables are 2'x5'. If you can bring your own folding table,
please do! We run out of tables before we run out of space to put
them.
We've got a new site up with actual content, including an
ever-expanding FAQ. Have a look and feel free to post about anything
not covered there:
http://vcfmw.org
See you in September!

I have a monitor for a Stardent workstation. It's a re-badge Sony, model
number 130-0001-01.
Free for pickup, or 1.2 * cost of shipping to recoup time and trouble if
you want it shipped.
Please respond soon if you are interested as it will be going off for
scrap in a week if there are no takers.

I'm trying to remember how to get a OpenVMS/VAX Hobbyist license. I have
the media. I have an account number for Encompass US, I just don't remember
where to get the license.
The title says it all. I'm looking to repair/configure a OIS 527 24k RAM
board for my Challenger 4P. Anyone have or know of the existence of a
manual for this board?
Thanks
Terry (Tez)
