Showconfig will show you something, but it won't show you if the memory is working. For that you need the CSA utility as the memory does not autoconfig.
This unit appears to have the SRAM and 4MB DRAM options, so you'd need to run csa-mmr SRAM DRAM 25. (You can use the SRAM as ram, or as a local ROM shadow - use SROM option instead of SRAM
)
(where 25 is the speed of the CPU).
You can also jumper the CSA-MMR to run in 68000 mode if the 68000 is installed on the unit.
So it isn't just "plug it in and see if it works". You need to read the manual, check the jumpers, run the software...
The software is available on the net, as is the manual. If anyone buys this and needs a hand, drop me a PM: I have two MMRs, both get lots of use, and both are great
