Apple IIgs - IIe keyboard

As mentioned in my post about IIe keyswitches, I acquired a couple of IIgs machines at the same time as the IIe (along with an AppleColor RGB monitor) - but no ADB keyboards or mice. I've just checked over both systems; one has an Apple memory expansion board fitted (2MB, I think) and the other has a Harris GS Sauce memory expansion board (also 2MB via a pair of 1MB simms) and what I think is an Apple SCSI board (nifty!). Both seem to power up OK and sit there trying to boot from non-existent media (display via composite; I don't know if the CRT monitor works - it's on the to-do list to make a cable). Anyway, the machine with the SCSI card looks to be an earlier board, and has a keyboard socket soldered to the PCB. Wikipedia seems to suggest that this should accept the keyboard from my IIe, albeit with reduced functionality over a genuine ADB keyboard - however, is it as simple as plugging it in, or are there other tweaks that are necessary for it to work? (e.g. perhaps worst-case a ROM change for a ROM that I don't have!). Although I'd like to get an ADB keyboard and rodent, I'm curious to see if the IIe keyboard will work in the meantime... cheers Jules
