## Board `PH00524-2`
|
|
|
|
|
|
|
|
|
|
The board controlling the vacuum valves does not show up in the schematics
|
|
|
|
|
delivered with the SEM. To us, it seems like the functionality was updated by
|
|
|
|
|
merging a few of the boards from the schematics into a single board with even
|
|
|
|
|
more smartness.
|
|
|
|
|
|
|
|
|
|
`PH00524-2` contains connectors named `FK*`, `FM*`, and `FL*`, leading to the
|
|
|
|
|
assumption that the boards `FK`, `FM`, and `FL` have been integrated into it.
|
|
|
|
|
So far, the connectors seem to match up with the ones shown in the SEM schematics.
|
|
|
|
|
|
|
|
|
|
There is also a Z80 based system + an EEPROM on the board.
