With 8 uVAXen around the batteries are a known item. Also the PRO and
a few others used same battery. If you blast them run them through a few
charge/dischage cycles and they hold up fine. Not if there is much fuzz

It might take a while to find a working permutation of PC/controller, but
that might be a viable solution for me.

Um, by your numbering scheme, 7 and 8 are H and J, not E and F.

TT is DRV AC L and VV is RX DMA INTR L. These are the extra connections
used by RX211 and RXV21 controllers, and I expect RX28 also uses RX DMA
INTR L.

ObNitpick: That's the reverse of the conventional numbering; Berg
connectors with letters have the red stripe at the A end, which is on the
left of the pin header (looking into the pins) while all other headers
which are numbered have pin 1 on the right.
Merry Christmas!

As far as I know, they're the same thing, just sold with different
operating software.
I'm now sure I don't have the floppies that "belonged" to mine. They may
be at a friend's place, but I won't be able to tell until after the
holidays. So, I guess I'll have to download some from David's site, but
before I do that, I'll have to figure out which PC with which floppy
controller can read/write my 8" drives, and before *that* there are several
other logistical problems to sort out. So it may be a while.
However, I did check the RX02 printset and the RX8E Maintenance Manual, and
I see that the RX8E (and RX28, RX11, and RXV11) only passes 9 signals to
the M7744 (which is the microprogrammed controller in the RX02). The RXV21
and RX211 use two more: the RX DMA and RX AC signals. These 9 signals
(with corresponding grounds) happen to be every second pair (pins A/B up to
PP/RR) along the Berg connector so it would be logical to assume that they
match the pairs, in order, connected to my D-connectors, which have exactly
18 pins fitted. I'll give it a try when I've cleared some more space.

AOL started out as Quantum Link or Q-Link and was for Commodore computers.
I still have the original BETA software on 5-1/4 for my VIC-20.

I do still have an original floppy containing a DOS client for AOL, and
something a little earlier- AOL either used to call their server PC-LINK
or PC-LINK was a seperate service offered by AOL to users of Tandy's
DeskMate software.
But a friend who was the early AOL adopter from whom I got these disks
told me that the reason he had to upgrade to a PC that was Windows-
capable was that AOl was discontinuing the DOS-mode service.
Whether DOS-mode meant text mode or not, I'm not sure.
As to the file collections, I was a CompuServe and BIX user
>from '85 to '87, and most of the CP/M stuff was the same, most
of the Mac stuff was the same, etc. I can think of one notable
exception that I preserved- source code for a threaded BIXMail
reader, written in DigiTalk's version of Smalltalk.
It was the forums that set the various services apart. I saved
tons of message traffic, but I lost most of it through platform
switches, crashes, early viruses, etc. I do still have some of
the BIX Smalltalk forum traffic saved.
What I wish I had were either printed or electronic sessions

And before it was AOL, it was QuantumLink for the C-64. I believe I still
have one of the QuantumLink diskettes around somewhere.

Home Of The TRS-80 Model 2000 FAQ
Just got in several pen based computers. They all seem to date from about
1995 so they are Off Topic but this is the best collectors group out there
for information
One is a Kalidor K2000, a very nice small ruggedized computer. I love it.
This one doesn't have its power supply so I have yet to get it to power up.
Does anyone know if the power connector is center positive or negative? It
says it needs DC 15V, 1.3A.
Any Websites? Software out there? I guess the company is out of business.
Does anyone know what happened to it. Who might have bought it.
There is also a Norand Pen*Key 6600 Windows that seems to be related to
Intermec, the bar code people. This one had it's charging base and powers up
as a DOS device. I couldn't find anything out about it but that there are new
versions 6642 still avaliable..This was in Intermec's site. Any others?
Software? It dates to 96 and I think has a i80486 for the processor.
There is also a Dauphin with a broken glass, maybe display. I haven't looked
at it yet. I found the Dauphin parts site.
The fourth was a Grid 2260 that I also have powered up. It is a little rough
but works. Boots to the password. Does anyone know how to get past it without
a boot diskette. I haven't looked yet for websites but I think Grid stuff
will be easier to find.
My Surplus dealer actually got in about 4 Grids, I just brought one of them
home to look at. I don't know what the others are but I suspect the same.
Since this is OT please contact me off line unless it is info that all would
be interested in.
Thanks for the help.

I think so if the floppy chip supports SD. I have not tried.

Do you have anything else to write to the RX02 from? If so you can
write my images, if not I can make you a copy, email me if needed. I will
buzz out the VT78 floppy cable.
This is the pinout I got by buzzing out the adapter cable I made to go
>from the DB25 on my RX02 to the 40 pin cable from the RX8E.
If the pinout was in a document I can't find it, I may of
gotten the pinout by buzzing out the cable in the drive.
Pins 10,11,23, and 24 are not connected in the cable from my VT78 but
pin 25 is present. I don't remember why my adapter cable has
extra pins connected.

So long ago I had forgotten about doing it, I posted a message to this group
looking for information about Richard Didday and/or Matrix
Publishers/Dilithium Press. Just a few days ago, Richard e-mailed me out of
the blue, responding to that message. Either he's really been stuck in the
"Symbiosis Through Transmutation" device all this time, or he suddenly
started reading archives of this group and saw his name. In any case, he
has kindly given me permission to scan and post a sort of funky
computer-cartoon book of his that was published in 1976. I reduced the size
of the scans substantially to make for quicker web viewing, but if anyone
wants a full-sized (300 dpi) scanned copy, let me know. To view it on-line,
go to my "Historic Computer Publications" page at:
http://incolor.inetnebr.com/bill_r/historic_pubs.htm
and scroll all the way to the bottom. Let me know what you think!
