Hey, here we go again. The Televideo's seem to be in their retirement phase ;-)

Correct. The TS806-10 had a 10Mb drive. Actually, you'll have only 17MB
to use. :-(

Thos should be TS800-A's, which are full Z80 systems, but without disks.

Mmmost is a program that runs on the 806, and takes care of the 800's disk I/O.
It also provides a rough form of protection, and some printer spooling.

It should boot from the HD. Press the reset button again immediately after
booting if it tries to boot from floppy.

??? The HD should be inside the 806 case.

As far as I know that is the case.

If noone in your neighbourhood can help you, I'll send a copy.

I'm not sure. I had a 806/20, but it was scrapped when the HD gave out.
Maybe the cables are still somewhere...

I can check the hardware manual if you like.

As I said, Help in the states would be fastest, but I'm available as
backup :-)
