Hi,
gee, in my zealous bargain-hunts I keep being burned. Two bad
CPUs before and now I thought I had a bargain with two UDA50
sets another KFQSA and a DEUNA set. However, as I unpacked
yesterday, I noticed that the KFQSA was missing one socketed
chip (approx 40 pin DIL, black right in the middle.) Also, one
of the UDA50 boards the M7.65 I think is missing a whole set
of 10 or so socketed chips all of equal size on the side.
My hope is that those are ROMs that may not be needed unless
booting from KFQSA or DEUNA is required, but that's a very
remote hope. Can they be replaced? Probably makes no sense.
grrr,
-Gunther

Ow. Sorry to hear that.
I noticed that the KFQSA was missing one socketed
chip (approx 40 pin DIL, black right in the middle.)
A microcontroller? A T-11? It's too new for my stuff; never even
seen one. Unfortunately, the picture in the Visual Field Guide at
http://vaxarchive.org/hw/vfg/m7769b1.jpg is none too legible.

If I had a UDA50 at home, I'd be glad see what's socketed on it, but I
cannot. Looking a a KDA50, I see lots of AMD PROMs that resemble
what you are describing. Those may be similar in function, if not
in content - http://vaxarchive.org/hw/vfg/m7164.jpg

Not that many ROMs. They are likely to be ROMs for the state machine
onboard the controller. Boot ROMs for the VAX live in places other
than on the peripherals, and tend to be small, both in quantity and
capacity.
You are probably hosed. :-(
Can they be replaced? Probably makes no sense.
Yes, but finding blanks will be more hassle than finding a dead board
and scavenging them (possibly what has already happened to you). It's
worth trying to see if they work, but with missing bits, they may have
been parted out for a reason.

yes, another hit, I know what you mean. The UDA50 has more
though.

On my KFQSA, this chip is labelled
T 23-081E8-00 9205EAI
TC 531024P-15-F814
(C) DEC 89
So, it looks like something proprietary to DEC. It might be a ROM,
but as far as i can see from following the board traces it has
something to do with an i8097 nearby...
'hope this helps

The part number is 23-081E8-00; 23-class part numbers are ROMs.
It seems to me that you wouldn't be violating any copyrights making a
replacement copy for another duly-licensed KFQSA board.

I managed to delete the original posting to this, so:
Would it be helpfull for the original poster - Mr. Schadow, i think -
if he had a binary file of the contents of the KFQSA-ROM?
I am also able (and willing, of course) to burn 27c1024 eproms.
Contact me off-line.
