A subscriber over at the Vintage Computer forum has an interesting

Does it ring any bells for anyone?

This is an 8MB RAM board for a Sun 3/200 and Sun 4/200.

Sun 9U VME ram board. 24mb from a Sun 4/2x0 maybe ? Might even be just
8mb or 16. In fact, I think 16mb is more likely.

The part number on the white tag by the ejector handle will tell the story.

It's an 8MB board. They didn't make 16MB or 24MB boards for those
systems.

Looks like a large-case VME memory board. Sun-3/Sun-4 era? If so,
there might be a Sun-format part number on a tag or on the board
itself, like "501-1333"

Maybe one of these:
Sun-4/260/280
501-1102 8MB ECC
501-1254 32MB ECC
501-1451 32MB ECC
501-1576 16MB ECC

Oh and it looks to have been stripped of parts and is more a really
dangerous Frisbee at this point. Picture is kind of blurry though. If
you read the first 7 numbers on the plastic tag on the top ejector you
can look it up easily.

Looks fine to me.
Those are ZIP chips. 288 of them. If that's 8MB (which I believe it
is), those are 256Kbit DRAMs. 1MB chips would make it 32MB.

Check out the number of empty sockets below the bar. Looks like about
8 empty sockets. One or two as spare I could understand but, that looks
like most socket IC's were pulled. Might just be the blurry picture though.

Ah. Down there. Yes. I do see a few missing DIP packages. When you
said totally gutted I envisioned an entirely different amount of
removal.
I can't comment on what belongs where on that era of board. I'm sure
there are people here that would know from experience.

:-( We ran so many of those it'd make your head spin.
Thinking about it, though, info is starting to come back to me. Look
at the plate on the top edge of the board. If the LEDs are at the top,
near or underneath the part number and serial number tag, it's for a
3/200 or a 4/200. If the LEDs are toward the middle, it's for a 4/400.
They are incompatible. This is likely the latter, given the ZIPs, and
it's probably a 32MB board.
As others have said, look at the plastic tag on the ejector handle.
The first seven digits are the part number.
I apologize for my misinformation earlier. (hopefully anyone searching
the archives in the future will find this message as well)

The 32MB 501-1333 for the 4/400 uses ZIPs but also uses (8x) square PGA
AM29C660 instead of the large DIPs so that is not the board. I have a
501-1333 right in front of me at the moment.
On the 501-1333 all of those socketed DIPs are PALs. If those are missing I
doubt they could be replaced.

New subject: Other boards, was Re: ID memory board?
How about the rest of the boards?
http://www.vintage-computer.com/vcforum/showthread.php?30062-storage-
auction-help!!!&p=218808#post218808
The first one is a mystery--DIO board of some sort?
The second one we know (Sun memory)
The third one looks like a fiber optic transceiver board
The fourth one I guessed as part of a tape drive, but that's just a
hunch, owing to what seems to be 9 analog channels.
The fifth, the homebrew one with 4 RTL PDIPS, a bunch of TO-220s and
some resistors I figured out as a 2-decade BCD counter/decoder. What
for, I have no clue.
I like games like this,

Luckily I have access to the latest in CSI technology and was able to
isolate, zoom, and enhance to reveal what appears to be empty sockets.

I think the 16mb card was the identical board though not fully populated
with ZIPs.

I could upgrade amigas to the end of my life with just one of these
boards worth of zips! :oD

car!")
