I would appreciate the following information on the Timex/Sinclair ZX81
or TS-1000 computer:

1. Are the schematics for the computer and the 16K RAM pack available
   anywhere?
2. Does anyone have any documentation on the SLC/ULA chip on the main board?
3. Is composite video signal available anywhere on the board?
4. On poer-up, is it possible to start execution in ROM other than the
   OS/BASIC, and if so, how?
5. Does anyone have official or disassembled source of the OS/BASIC?
6. Is there any documentation of user callable routines in the kernel?

I would appreciate any information on the above.  I will collect and post
the responses.  Thank you.
