Re: Pascal for ZX81

one more doubt: Control Technology seems to have had a PASCAL language for the ZX81.
Semper Software was clearly advertising a simplified PASCAL subset specific for the ZX81.
They could have been 2 separate products.. but also a simple reselling operation.

Re: Pascal for ZX81

that's becoming an interesting mystery, there are several references in archive.org talking about this product, but no clue on how actually using it This article looks promising, though: T-S Horizons n16_0021.jpg T-S Horizons n16_0022.jpg T-S Horizons n18_0021.jpg T-S Horizons n18_0022.jpg I'll try ...

z88dk v2.1 released

It's February, so that must mean it's z88dk freeze and snapshot release time! Unfortunately we ran out of time to complete some major projects, hopefully they'll be available in the nightly builds later on in the year. However, as usual there's hundreds of changes ranging from more targets, to chang...

Re: ZX80/ZX81 tape load "optimizations"

I can't understand why, but it is the second case.
Experimental results ;)

for optimizations, try z88dk-appmake ;)

Re: Can anyone remember the url of Sinclair’s old websites?

it was "sinclair radionics".. something. I tried to spot it on the wayback machine, but no luck. I found this, though.. https://worldradiohistory.com/BOOKSHELF-ARH/Author-Groups/Clive-Sinclair/The-Sinclair-Story-Clive-Sinclair.pdf EDIT.. I think it is a matter of point in time ? move forth and back ...

Re: ZXForth. Plagerism,clever marketing or something else?

forgive my late, slightly unrelated comment. I was a lucky participant of a scientific publication in recent years related to the eastern Europe computing history. My small contribution was mainly based on a tool we are including in z88dk, basck.c It simply looks in binary files for known machine co...

Re: ZX80/ZX81 tape load "optimizations"

I did on z88dk, one of the appmake options squeezes the wav file by reducing the pulse count where possible and tries to set a more aggressive interval too. I found a similar trick in an historical program on an Italian magazine (supersinc), but the result didn't work for me, perhaps I got too few p...
