Re: PRYNT, POKU, bad ROM or ULA in TS1000?
Fixed now, looks like it was the ROM. Motherboard is a ZX-81 Rev 3, all ICs socketed.Pulled the Mostek ROM, cleaned it, re-inserted. Same as before. Inserted a Sinclair ROM removed from a very beat-up TS1000, all is good now. Incidentally, I wonder if when these machines are assembled at the factory...

Re: PRYNT, POKU, bad ROM or ULA in TS1000?
Interesting responses, thank you. Some knowledgable folks here. ("There goes one now?" don't get that one)
Anyhoo, I will check the pins first, clean them up if necessary and report back. Funny, my primary TS1000 has been completely trouble free (knocks on wood).
Cheers,

PRYNT, POKU, bad ROM or ULA in TS1000?
Hi Smart People, I have a couple of TS1000 "new in box." Well A fellow wanted to trade with me for one of them so I unboxed it in order to test it. When I tap the PRINT key, I get "(PRYNT(" and when I use the POKE key I get "POKU." Have you folks ever seen this behavior? My first thought was somehow...

Re: How to iterate the iteration
You folks that know BASIC well may indeed be slapping your foreheads at my question...I keep thinking there is a nested solution, or something else.
Thanks again for taking a look.

Re: How to iterate the iteration
Hi Mark,
Thank you for taking time to reply, but I am aware of that method. I am interested in solving this concept.

How to iterate the iteration
Cool ZXers, Say I have this: 10 LET X=1 15 FOR T = 1 TO 5 20 PRINT X 25 LET X=X+1 30 NEXT T RUN 1 2 3 4 5 But what if I want the whole thing (lines 10-30) in another loop (if that's the most elegant approach), so it does: 6 7 8 9 10 The next time I run it. And so on, each time I run it, the sequence...

Re: Double buffer grey scale?
Gray effect aside, I would love to see how you are double buffering for smoother animation. Please share an example.
Thank you.

Bob Fraser ZX-81 Machine code articles. Missing parts.
Hi ZXers, I am working on a simple game for the ZX-81 and want to use some machine code routines. As a 48 year old I would like to actually finish this game, instead of abandoning it as we did in our teen years. I stumbled across a series of articles by Bob Fraser for the Timex Sinclair User magazin...

Hello SirMorris and Co, I just had time to load each PowerBasic version (with ZXPand intalled) and note the results: PowerBasic (excellent) download includes four versions: 8k, 12k, 16k, and 32k. 8k: upon being loaded and run, screen clears quickly (too quickly to fully read the installing...please ...

Anyone have ZXPand and **Basic working together?
Hi ZX Folks, ZXPand is amazing, and Power **Basic is great, adding Data statements, a flashing cursor, and more sensical error messages. Does anyone have them working together? I tried the 8k, 12k, 16k, and 32k versions of **Basic and they all exhibit oddities. Me being new I presume the two are usi...
