I have this 1 slot MVS that is giving me a video ram error. After doing some research and finding some old posts on neo-geo.com it seems that one of the the 2 fast video ram have failed. Is that correct, I found some replacement ram on ebay, unless there are any KLOV members that sell these.

I've seen you commented on this issue before @channelmanic does this sound right, and do you sell any of these ram?

Just a quick update, I ordered the replacements from ebay, they will be in a few weeks or so. Checking the old ones with a ttl logic probe show the data lines 4,5 & 6 on one of the chips are stuck low, even when power cycling the board they stay stuck low.

Yes. $8000 is the CXK5814 SRAM. You can use 6116-25, 35, or 45ns as well.
Thanks! I believe this is the 6116 you are referring to correct?


And I assume the 35 in the part number is the 35ns. I'll get these and some sockets, I really don't want to wait 3 weeks for the ebay chips I ordered to come in from china so I'll get these as well. Thanks again!
 
Final update, I bought some of the 6116 ram and some duel wipe sockets from arcadepartsandrepair.com they arrived today and after installing... the MVS lives again!
