I have an example of this Module though it didn't have the Socket Module with it so I had to make a replica.
Here is a copy of the Data Sheet for the Module:
Software
Here is a dump of the on-board ROM (R2926-11) which I have started to disassemble:
The board is located at $7000, the I/O at $7000 and the EPROM from $7100.
The PROM Programmer application is executed from $7100 and provides the following single character commands:
R - Read PROM
V - Verify PROM
P - Program PROM
E - Erase EEPROM
C - Checksum PROM
S - Checksum Memory
I - Invert Memory
A - Alter Memory
N - Change PROM Type
? - Display Menu
T - Toggle Verify Mode
X - Exit
L - Load with Offset
D - Dump with Offset
F - ?
Hardware
Here are photos of the two sides of the board:


Board Configuration
The board has a single bank of DIL switches and a couple of links.
The DIL switches set the base address of the ROM and I/O.
I haven't worked out exactly what each switch does yet but for normal operation i.e. with the board at $7000 they should be set as follows:
(four assign the ROM Base address, five assign the I/O 256 byte page within the ROM range and the remaining switch's are associated with Bank selection)
| Switch No. | UP (Open) / DOWN (Closed) | Function |
| 1 | UP | TBC |
| 2 | UP | TBC |
| 3 | UP | TBC |
| 4 | UP | TBC |
| 5 | DOWN | TBC |
| 6 | DOWN | TBC |
| 7 | DOWN | TBC |
| 8 | UP | TBC |
| 9 | UP | TBC |
| 10 | UP | TBC |
The two links configure the ROM (4K, 8K or no ROM), again for normal operation (4K ROM) they should be set as follows:
E1 position A
E2 position A
There is also a trim potentiometer (VR1) which sets the Vpp voltage (measured at the adjacent test point).
