Re: Speech Synthesis
Thanks - that's of interest to me as I'll explain below. ... I had started on the Spectrum by writing machine code routines (called using FN statements from ZX Basic IIRC - the code is in one of my early Spectrum books) to get simple zaps, etc from the Spectrum speaker as opposed to the usual simpl...

Re: Speech Synthesis
Looka like QTALK was a serial device that synthesized speech for the QL.

Re: Speech Synthesis
Thank you Dilwyn!
Btw, here is what digitized speech sounds like on a ZX81...maybe someday we can have that on the QL too...

Re: Speech Synthesis
Thank you Jan, this is amazing. I will take a look at it and see if I can figure out how the digitizer on the ZX81 worked. Maybe we can get some audio out of the network ports as a sort of pseudo sound card. I've read up on the Kansas City standard (4 pulses for zero and 8 pulses for one) is pretty ...

Re: Speech Synthesis
Wow, that's pretty interesting that the network port could save and load ZX tapes. That would suggest you could play digitized sounds (voice and music) out of it. I know there was software on the ZX81 that turned it's mic port into a small electronic piano. I have the Z80 machine code that outputs d...

Re: Old media - could it be 3D-printed ?
I think for MDV's it would be simpler to just create a small mold and create the parts that way. Doing molds isn't that difficult, just requires a bit of hand labor. I had planned to create a mold of the QL case (bought top and bottom on eBay for that purpose) but COVID has interrupted that since I ...

Speech Synthesis
I recently recovered software for my ZX81 that I bought in 1985. It was labeled a TS1000 Speech Synthesizer though in reality it just had 273 words digitized (over 9 libraries at about 500 bytes per word). Today I was able to recover the BioTalk program...after years of sitting in a box, the first p...

Re: driving magnetic heads ( floppy, auudio etc)...
I found this resource from the Council on Library & Information Resources (CLIR) useful for magnetic tape information:

Especially this subsection on what can go wrong:

Gold Card initial release date
What year did the Miracle System Gold Card first come out? It's not stated on the QL Wiki.

Re: Loopy bugs
By 'grammar' I suspect you all mean syntax 'railway line' graphs, as defined for example in Jan Jones' handbook. I tend to use Backus Naur Form (BNF) to specify a grammar though it's an old format that may not be as common as the inline mechanism used by lex/yacc, antlr and the like. Syntax diagram...
