Actually, I didn't notice any RAM on the board
that was scanned
and put up on the web. But I did notice a little 8-pin chip that
I didn't recognise. A Google search for "UM8326" revealed
this information about a board called "Transcopy":
That's a data separator for FM and MFM data. Using that chip, there is
no way to read other formats like GCR. So it's not equivalent to the
Central Point stuff.
The Central Point boards let the software read the raw data from the
drive at a point *before* any data separation would be done in a "normal"
disk controller.
