Re: ZX81 to ZX Spectrum conversion possible
Note that with all tape operations on both computers, all the timing is done in software. I'm in the US...I wonder if that's adds any difference. It's running on 9V DC...would it be a 50 vs 60 Hz issue? When generating the .wav files I think EightyOne was set to ZX81, vs TS1000. Should I set it to ...

Re: ZX81 to ZX Spectrum conversion possible
Covert BASIC into BASIC will leave you with manual conversion for not compatible BASIC, like SCROLL, UNPLOT. Besides that, PLOT on the ZX Spectrum is a whole different resolution. Yup, that part worked actually pretty well, with just some commands needing to be re-mapped. As you say, PLOT/UNPLOT (e...

Re: ZX81 to ZX Spectrum conversion possible
So I'm using the 1982 ZX Slowloader by East London Robotics that converts ZX81 BASIC to Spectrum BASIC. The conversion works on the EightyOne emulator set to 48K Spectrum loading a ZX81 audio file, but not on actual hardware (well, it runs but can't seem to recognize any ZX81 audio files). I don't w...

Re: ZX81 to ZX Spectrum conversion possible
A very old thread but I recently played with ZX Slowloader and it worked pretty well. It does most of the conversions for you, though it stumbles on some graphics characters, especially if you use CODE/CHR$ combinations. I did have issues with using actual hardware. No matter what I did with volume ...

Z88 LCD panel
Not much Z88 content on here. I did a general search and nothing came up. Maybe I'll be the first person to post. In any case, I've had mine since about late '89 I think (or early '90). [Edit: I was looking in the wrong place and the sys admins moved my post to the appropriate area.] When I took it ...

Re: Understanding ZX81 signals to Timex/Sinclair Printers
Thanks for all the feedback Mark. I checked by two spectrums and there is no inductor...just a coil looking thing by the power adapter. The ZX Printer has one of those too, but that's not the thing that overheated and is not shown as an inductor on the schematic (at least not the simple repeating ha...

Re: Understanding ZX81 signals to Timex/Sinclair Printers
L1 is provided to limit interference on the (nominal) +9V / +10V rail. It’s value is not critical. If it has continuity, then the copper wire is okay. If this got hot, it means that there was a short circuit on the (nominal) +9V / +10V rail somewhere. A short circuit like this should show up if you...

Re: Understanding ZX81 signals to Timex/Sinclair Printers
I just got a ZX Printer and plugged it into my TS1000 and it started to smell. Took it apart and it looks like he inductor shorted. I did find a solder ball between the top leg (that bends 180 degrees and comes back down) and winding, about 3/4 of the way up...perhaps it got caught in there while sl...

Re: Using MCoder2 in EightyOne
I had videoed myself back in spring when I did a multi-step compile of my Elite game...it's live now on my channel. I tried to do it the way I would have back in the mid 80's when I only had a cassette recorder, a ZX81 printer, and a 16K RAM pack. The only difference is that instead of saving to a c...
