But depicted is CT3780.
Oops, yes thanks for pointing that out 😀
Little bit more progress, installed the COM/LPT ports and expansion cards. I need to figure out the pinout for the PS/2 header before plugging it in. There are 5 pins and the manual specifies one as N/C, but doesn't label the other 4. I should be able to identify GND and +5V using a multimeter, that just leaves DATA and CLOCK. If I get these two the wrong way round first try it won't break anything, will it?
