    If you can get hold of an EGA card you can adjust the DIP switches to support a 5153 at EGA Mode 1 resolutions - 320x200 and 640x200 IIRC. Yes, it's a halfway house type solution, but works rather...

    WinImage worked a treat to create the floppy disks for my PS/2 Model 30 286. If your machine won't recognise it after that it would be worth cleaning the heads on the PS/2 drive.

    This week I've had the exact problem with my XT-286!

    The battery turned out to be almost dead, but not quite, hence it retains the time but does not advance.

    Luckily, this battery is still used...

    Did you adjust the dip switches on the motherboard to correspond with the new graphics card?

    Be careful, you might damage the card or monitor by plugging the incorrect one into it..

    The 5150 wasn't officially sold in the UK until 1983, so that rules out the Model A machines. However, I have seen two on UK eBay over the years, so they are out there..

    IBM EGA Card

    I'm looking for a genuine IBM EGA card to put in my AT. Must be an original IBM!

    The third one I've bought from eBay in as many years has also turned out to be faulty :mad:

    That receipt is VERY cool!
