CorComp 512K Ramdisk PEB card - firmware?

Recommended Posts

I recently aquired an expansion box for my TI-994a and installed was a CorComp 512K ramdisk card with 256K of RAM. Looking online I was able to find the manual for v3.1 of the card, but it appears that my card is only v2.42. I cannot run the "CALL RAMGR" command to invoke the ram disk manager program.

 

Does anyone know if I can get a copy of the v3.1 firmware and burn it to an EPROM to replace the v2.42 one on the card? If so, WHERE could I get a copy of the v3.1 firmware?

 

What EPROM is currently installed. A label on the EPROM covers the info on my card.

 

Thanks!

@atrax27407 probably has this eprom, his rates for a burned eprom are reasonable. He guarantees to give you a good eorom. Fyi.

Hi, I hope we´ll find it. Btw, when you dismount your eprom later, can you read it out that we have a backup of the older version ?

thx

I plan on saving the 2.42 version and uploading it.

Really? Great! I appreciate it.  If you can tell what type of EPROM (2764???) was used it would also be helpful.

I've burned the 3.1 firmware and installed it. The card seems to be working fine. I will need to do some testing later.

 

Here is the v2.42 firmware that was originally installed on my card.
