The only thing I got from the FCCID (GWV 76CG3) on the “SVideo with Composite” 
was “Color Frame Buffer I/O Card”

Possibly part of the "SPARC Card TV" partially described here:

You seem to be missing the upper board, though.

Most likely Sun's "TRI/S" token ring interface, 501-1932.

Probably the earlier Sun VideoPix (501-1706) in that case.

Help Identifying Mystery SBUS Cards

[Classic CMP via cctalk]

Hello all,

I was hoping to tap into the considerable Sun Microsystems experience within 
this group.

I picked up a significant quantity of Sun SPARC equipment back in the early 
00’s and due to life/children/etc. have only recently been able to start 
cataloguing it.  In particular, I had a somewhat tatty box full of assorted 
SBUS cards.  Amongst the usual GX / TGX frame buffers, ethernet and narrow SCSI 
cards were some more unusual ones I’ve struggled to identify.

I have photographed (poorly, I only have my mobile phone camera) the items, and 
they can be viewed here:

https://www.dropbox.com/sh/kv42ig8nucikt0p/AAAKMZkqn9r19Ti0yKllQ2g8a?dl=0 


Here is a text description of the cards, in case it can be useful:

(1) A dual-width SBUS card with no internal or external interfaces or 
backplate. Other features include 2x LSI chips 'LIA7321 EK7B7483' and 'LIA6371 
EK7B7484’ and a sticker displaying '7B7488 011 0110-014 0643 1700556 9651’ a 
barcode ‘J0BAW’.  I wondered if it might be a DSP of some kind?

(2) A dual width SBUS framebuffer, with space for a piggyback daughter SBUS 
card in the middle.  It features 3 x Bt457 RAMDACs and an Actel A1020A chip.

(3) A 3M fibre card, looks like a prototype based on the number of bodge wires. 
 FDDI? Marked '3M ASSY 78-8095-5382-5', ROM marked FOSSIL BD. 1AS8.

(4) Possible Serial card with a DB9 connector, although there’s WAY too much 
logic for a simple serial card.  Has a jumper for 4Mhz / 16Mhz which hints at 
maybe something Token-ring?

(5) A SBUS card with S-Video and what I assume to be composite.  Looks like a 
501-3019 on first inspection but there’s less logic and no heatsink on board.

(6) A rather beautiful (to look at) SBUS card by Performance Technologies Inc.  
This one strikes me as a multi-port serial card although I don’t have the 
breakout HD80 lead for it. Has a chip marked 820P010201 HG62S038R02F 9120, a 
sticker ‘120P010001' and on the back of the board '#595801-01 DC 9116 NT2V0 
94V0' and '124-01’.

Any insight would be gratefully received!

Thanks,
Austin.
