Yes, I thought that would be confusing just after I pressed 'send' Anyway - I have several
teledisk boot images for various versions of cp/m, and a i'm currently looking for an older floppy
controller, and some HD disks, so I can write them to floppy.

Bummer. You'll be wanting a pc with an old 51/4" drive, and old controller you will :)

Yep. Got all these.

Ooo! COLOUR graphics? Very posh :) I've only got the composite video one. Don't know if it's
colour, cos i've got an old panasonic composite monitor, but i'm sure it'll be monochrome.

Yes, I have a spare cpu with that exact version of COS.

I'm going to build a website for it - just a few pics, all the data I have, and all the software,
I just need to get around to doing it. If/when you get yourself a 51/4" drive and old controller,
just drop me a mail, and i'll send you the disk images.
