According to my google-fu & a picture on eBay
* the switches control resolution & timings.
* the board has a IMS G300G DAC, whose documentation is available from e.g. <http://www.transputer.net/ibooks/72-trn-204-00/graph1st.pdf>.

That would make the registers you write (p 85/pdf p93)

VDisplay      #X128
Linetime      #X129
LineStart     #X12A
Memlnit       #X12B
TransferDelay #X12C
Mask Register #X140
