And quoting Amiga Hardware Database:
Quote:
# memory four 64 pin SIMM sockets accept 64 MB RAM
# supports only special 4 or 16 MB GVP SIMMs
# SIMM sizes cannot be mixed
# 040 burst mode requires all four sockets to be filled up

jumper settings
J4 - SCSI drive: OFF - connected
J5 - autoboot ROM: OFF - disable
J7 - MMU: ON - disable
J20 - SIMM size: ON - 4 MB, OFF - 16 MB
J22 - burst mode: OFF - enable
J26 - DTACK pull-up for old A2000s: ON - enable

Does the board came with memory sockets fully populated? Are the memory SIMMs ok?

Does the 040 heats a lot?

If the 040 is cool (or even slightly warm), then you could have:

a) the oscillator crystal fall out the socket;

b) a busted CPU.

Check the crystal to see if it is in place and firmly attached and pray the CPU didn't busted for the lack of clock.

Also (carefully) pull off the 040 and reinsert it.

will the Amiga boot to work bench with the card installed?

I am wondering if you can access the early boot menu, pending on the kickstart rom you are using to see if the card is there to be used.

Good luck with this

Did you remove and reinsert the GVP SIMM modules several times? If you did, then it may well be that it did the trick.

The 64-pin SIMM sockets of the 030 and 040 GVP Combo accelerators I've seen so far were all rather fiddly - the SIMM modules tended to wriggle out of them eventually. (My current A2000 has the wires coming out from the PSU arranged strategically to keep the SIMMs in their place....)
