I have an M24 which does not have the bus converter card P1050). There are a couple of these cards on ebay in the USA, which makes it expensive for me, and I am not sure which of the two would be best anyway. There is another bus converter available in the UK, but it is PC1076 (IF 622), which my web searches suggest make it for the M280 (which was a 286 machine). Does anyone have any idea if this latter card might work in my M24? It certainly looks to be physically compatible. Regards Rob
