It probably need a GAL upgrade much like the other AE boards.  Can you read 
off what the silk screen text is written on the socketted logic ICs?  A pic 
or scan would be good too.  Maybe I can determine if one of the other GAL 
upgrades can be used on the Ultra.

Here's link to an example:

Notice just above the black shrouded 40 pin header the two ICs with the 
extra text written on them?  I'll need those numbers.  These for example say 
'GSPLD2A-Q' and 'GSPLD1A-Q' which just happens to mean this particular 
GS-RAM Plus works in a ROM1.  Had the larger IC said 'GSPLD1B-Q' it would 
work in a ROM3.  You may find the numbers are the same on your card.  If so 
then there's a good chance the GS-RAM Plus GAL upgrade will work for your 
Ultra card too.

If anyone else has an Ultra that works in a ROM3 please post your IC numbers 
for reference.  I may also bug you for your card to copy the ICs at some 
point if needed.  Thanks!  Also I could use a good pic of the Ultra.  Any 
links or scans would be appreciated.
