    Some success with the Advantage.

    Have now tried running the machine from a 110V 60Hz pure sine wave inverter and the picture is now stable.

    I have a replacement 50Hz PROM on order that I hope that will let me run without the inverter.

    I MAY even be able to relink the mains transformer to let me run it at 240V - technical manual indicates I should be able to do this.

    Quick update.

    50Hz PROM has arrived - after a quick lunch time test it seems to work perfectly. Thanks Larry for correcting the code for me, we should probably dump the file on bitsavers.

    Ian,
    GREAT NEWS! Glad it worked properly.

    Yes, send it to Al at Bitsavers to preserve.

    Well done!

    So, err, what about showing us some of its graphics capabilities? It does say "64K Graphics CP/M" when it boots..

    Yes - I need to get hold of the graphics demo floppy - still trying to work out the best way to get the hard sector floppy images to disk.
    Right now all I have is a bootable Wordstar disk with nothing useful on it. There is a YT video you can watch in the meantime.....
