Reply to JBW & locg : Yes it does have a 012 analog sta card in the last occupied slot, with 3 ports patched to a Compaq Deskpro 575 PC. From what I could see, it did not look like any AT&T VM.
Main screen had GVM Systems in upper left corner. Prior to the 012 card is two 408 cards. ( not 408 GS/LS cards )
The processor does not have a PCMIA slot, or fault indicator above it. Just SMDR & Admin ports.
I'm leaning towards a Merlin 2 vs Ledgend.
If it is a M2, can it be programmed with a BIS 22 set.
I'm searching for a downloadable Merlin 2 FP2 program manual in hope it can anwser some of my questions.
Anymore feedback or opinions would be greatly appreciated.

Thanks
