|cheers for all that help. |
i whipped out the old Acer CD drive, but there was no way it was going to fit in the space in the chassis. i've been told since that the compaq deskpro was built to only take a compaq slimline CD drive.
went down to my local pc repair people to see if they had any ideas. after scratching their heads one of them went off and came back with an old PC tower with isa expansion slots and gave it to me for £5. I've ordered some PS/2 to serial/din adapters for the mouse and keyboard and...should be sorted.
