Hi Jochen,
A solid state disc would be a great solution, however, wouldn't it be a
better (more general) aproach to work right off the unibus? That would help
anyone that -like me- has a unibus-cpu with nothing else attached to it.
If you have (?) the scematics of the RK611, how much work would it be to
put this into a fpga-design and add connect this to a (better four) CF-card
socket(s) Then a cheap 32mb CF card would become a RK07+ media...
If you follow the RK611-design, there is no bothering about driver issues,
just a patch to the block-count to get those extra 4 megs of a 32m CF-card.
A project like this would be a perfect entry for the VCFE of next year,
isn't it? (Hurry up, only 50 weeks left! :-)) )
Greetings,
Frank
Has anyone on here ever thought about putting up a site that
documents the collector interest or areas of specialty for the
folks who visit here?
If this sounds like a good idea, I'll create a site and host it.
It could have things like a "wish list", "current inventory",
"items for trade/sale", etc.
I know some of this type of thing exists elsewhere, such as
on Sellam's VCM site, but I haven't seen a place where I can
go to find individuals who have specific computers, parts, wants,
etc.
Other ideas and opinions are welcome. If this kind of thing
already exists, just enlighten me as to where it is located.

Are there any hardcore PHP gurus out there that can help me with an
unusual PHP construct (converting an array into a list of elements to pass
as parameters into a function)?
Please e-mail me privately. Thanks!

Hi Hi i came across searching VMX 5.5-2. there i found your contact. I need these manuals.if you please can provide me these manuals i wll be thankful.Regards,Karamat Ali Khan. I came across these DEC VAX manuals while looking for something else.
Am not selling, but will provide information from these if needed
non-commercially.

I'm looking for a manual and other info on this old 386 motherboard that
I am trying to build into a working DOS 6.22/WfW 3.11 system for playing
old games and to play around with DOS TCP/IP networking. The board,
according to the BIOS string, is from Wintac-Edom (The BIOS string is:
E0X3-1379-083090-K0 Beyond that, I can't seem to find any other info on
this, as there are no other identifying markings that I can find.
Here's a pic of the board...
http://webpages.charter.net/scarletdown/Geekworks/GKW-Edom-MB-0.JPG
Anyway, I currently have it set up with a VGA card, a 16-bit MIO card,
Adaptec AHA 1542CF SCSI adapter, Databook PCMCIA card reader, PnP
Soundblaster, 3Com EtherLink III 3c509 NIC, SCSI CD-ROM drive, 210MB
Hard drive as the master drive, 1.5GB hard drive set as slave (will put
EZ-BIOS on it shortly to make it useable on this old board), 386/DX-25
(or 33, I don't remember at the moment which) CPU, and 8MB of RAM in the
form of 8 1MB 30 Pin SIMMs).
So, when I boot up, she goes through the memory test, then the SCSI card
does its self-test. After that, I get an error about the hard drive
(this is because I haven't set either drive up yet), and am given the
option to hit F1 to go to setup.
Well, when I go into BIOS setup, everything freezes on me, no response
at all from the keyboard, and all I can do is hit reset or power down.
Odd thing is, though; I can boot up with a DOS floppy and access the C
drive just fine, though the D drive is not yet visible of course.
What would be causing this freezeup when I go to BIOS setup? And, where
can I find a manual for this board?
Thanks
Hi Everyone
I have some (3) PDP 11/60's that I'm trying to get running.
I did manage to get all of the Power supplies going, removed
all of the cards and cleaned them. check the cable routing
and power supply voltages. I have got the LA-01 and TE-10's
running. These systems have been setting since 1986.
I do have All zeros in the console display. No other console
lights come on ???? . no responce from any keyed input.
The Memory cards all have power LEDS turned on (m7984 Mos)
The Memory controller has a LED but it's off ?? (M7983)
These are from a large test system and each has 5 to 6 cabinets.
So in time I want to trim these down to the Base double wide corp.
cabinet only. It looks like the board label on top of each card
cage matches the cards. I believe the grant cards are all there
where needed. Most of the slots in the 2 main card cages are full.
The memory back plane does not have grant cards in the open slots
and from the manuals I have, this looks correct ??
The question for now is what do the LEDs on the M7878 (11/60 status card,
all on) and M7872 (11/60 micro word card, all but the top 3 are on)
stand for or tell you. I do not have any manuals on the cards and a
quick search did not turn up much.
I posted this yesterday and it did not show up so this is a second
post. so if you see 2 of these you know why.
Yes, I might need help with my power bill also.
Thanks, Jerry

If anyone can provide me with Dan Cohoe's phone number I would really
apprecate it. I need to give him a call about meeting up with him in
Dayton, but have managed to discard my copy of his phone number.
Thanks to anyone who can help,
Pat
