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. M.
