Greetings all! I recently received a ZX-81/TS-1000 (can't tell, the case was gone and the TS-1000 is marked as ZX-81 on the board - doesn't matter anyway..) It has a second set of ROMs, selectable via the channel switch, which comes up as: PLURI-FORTH BY TREE SYSTEMS COPYRIGHT 1983 Does anyone know about this, or, hopefully, have a manual? VLIST tells me the words but a manual would be really nice. I've since mounted the board with homemade keyboard (which I didn't make) in an old Apple II case. Add a few connectors on the case and I'm all set with a nice little 16k Forth machine! - Ron Kneusel rkneusel(a)mcw.edu
