Ok, I have somewhere between 350-400 old computers in my shed that I have promised my partner that I am going to repair/rebuild.

Part of this is potentially realigning 40 track floppy disks, to do this there are special alignment disks that were used.
An 80 track alignment disk would also be nice but much less important as only a couple of machines I have use them.

If anyone is interested they are mostly TRS-80s, CPM based machines (Osbourne, Kaypro, etc) though I have a large collection of sinclair, amstrad,commodore,atari,acorn,panasonic,etc etc etc.

I have a growing collection of service manuals, spare parts, including new floppy drives, CPUs, RAM but getting some diagnostic tools / software for some of these old machines would be useful.

Cheers

Hey, have you listed a price, location and how much shipping would be to other parts of New Zealand? Also if you are asking for a PM make sure your Privacy settings allow your account to receive PM otherwise people can't contact you.

No proper list and not that interested in selling anything yet as I want to keep a fair amount for my own enjoyment.
At this stage I want to get as much stuff up an running and keep some of the best bits.

But I do have ZX81s, QLs, Spectrums, Spectrum3+ and various RAM packs, microdrives etc

I have some other real oddball items such as a delay loop from the old post office bank machines, apparently they could store 1 byte in this delay loop.

I also have a Jaquard bit slice machine with a 10Mb hard drive that I can NOT lift by myself !
A PDP 11/23, dome Data General gear, Some NZ build Polys, a German made system that uses hard sectored floppy disks.

The 1970s/1980s were the most interesting years for computers, lots of new ideas were tried from hundreds of different suppliers.
