I heard before that 2114 are considered unreliable. Is there an overview
of brands that are not reliable? I have a computer in repair, a DAI,
8080 CPU with special stack RAM implemented with 2114s, so that could be
the problem. But it would be nice to be more sure before soldering them
out.
An image of the suspect RAM is here:

I don't suppose anyone on this list has a DEC AXP 3000/800 motherboard
and/or I/O board kicking around? I have had one of these for a while but
it has a problem with one or other boards. If I can't get a spare I
can't justify keeping it and will have to ditch it. I'd rather not,
obviously.
Regards, Mark.

(This is a resend - I never got my original message back so I suppose it got stuck in that list server hiccup a few months ago...)
Hello everybody,
we recently acquired a HP NetServer 4/33 LE (later upgraded to 100 MHz) for the University computer museum and are trying to get it going now. This involves some configuration changes for which one needs a configurator disk - the one we got with it is flaky (reads unreliably). We did download the Netserver LE ECU (EISA configuration utility) disk images from HP's website but when the changes are made, the program complains that the actual system board ID differs from the one in the configuration file and does not save the new configuration to the CMOS.
Clearing the CMOS via DIP switch did not improve the situation. We finally got the original disk to boot once but got the same message. A BIOS update/reflash is not possible because the update utility wants Video BIOS shadowing enabled, which would - you guessed it - be done by means of the configuration utility.
Am I doing something wrong here, do I have the wrong disk image or is our mainboard toast?
As usual, thanks in advance...

Hi,
I have a blog called "Vintage Technology Collector" (http://vintagetech.org)
and working on an article called "buying/selling vintage technology". I
have bought several vintage personal computers and device over the years,
and one of the best and most reliable sources of this equipment is eBay. I
am wanting to find out if anyone has any better places for buying/selling
vintage electronics.
Thanks,
Jason
Hi,
I have this Data General Nova 1220 sitting here which seems in good shape.
But I don't have the front panel key, which is in the "lock" position.
The PDP11 keys I have do not work :(
Any hint ?
Thank you !

Hi Dan,
I am interested, but you need to think about shipping it, on my cost no
question. On the other hand, I will try to organise a VAX-Station, I think,
I can get a 4000 or something like this, maybe more.
With best regards
Gerhard
PS: Do you have pictures?

Hi Fred Jan,
are you sure those are 2114's?
Not that I am 100% sure, but to me those are 2111 RAMs, 400 ns types.

I still have the following S-100 boards for sale if anyone's
interested:
Wameco QMB-9 "The Little Mother" 9-slot motherboard with five
connectors.
http://tinypic.com/view.php?pic=20qzvq0&s=4
8K static RAM (2102) board by Ithaca Audio, fully socketed and
populated. Needs a couple of heat sinks for the 7805 regulators.
http://tinypic.com/view.php?pic=29lefr8&s=4
Piiceon 8K Program Saver board (2708 EPROM programmer). Complete
except for the TL497CN switching regulator chip. Includes two
2708's, can hold eight.

NOTE: The above boards were never powered up or tested (lost
interest in the early '80's). No guarantee they will actually
work!
VB-1B Video Interface card by Solid State Music. This one was
actually working with a different (homebrewed) 8080A board way
back in 1979. I think it's 64 characters x 16 lines, monochrome of
course.
