Re: "Inline" BASIC Extensions
Hi Greg nice demos :) Maybe the subroutine's interface to the machine code can be done more easily using LPRINT ; if printable characters need to be passed to m/c. Instead of poking the characters into the machine code: 21 POKE L+1, CODE C$(1) 22 POKE L+3, CODE C$(2) using 21 LPRINT C$(1 to 2); is e...

Re: IF I would write a book about coding a 1K ZX81.....
What style of writing would you like? For instance I could write it as telling my story or just like a manual explain how to get most out of 1K Maybe the structure could be like the ZX81 BASIC Manual? It is well done to learn BASIC. And to learn C, the same structure was used: https://forum.tlienha...

Re: RAMPACK and Hi-RES mod ?
Indeed. I STRONGLY recommend to connect the ram's /OE only to /RD AND /RFSH, never directly to GND or /CE!

Re: Hangman game
Hi Stefano something is strange: when I enter the first letter of the secret word to be found, it is shown on screen (upper line), but is overwritten by the second letter entered later. All following entered letters are shown correctly on screen. I used a real Zeddy with BigBang-rom and EOV1.23 (sam...

Re: Pascal for ZX81
Thanks for this Christoph. :D It is a shame that partial Pascal cannot do more because I think it is good to have other languages for the Zeddy and try a different way of working. It is also a shame you cannot access the full 32 k of the ZXpand which for example H4th can do ( although it still uses...

Re: If the R reg is used for video, how does it find time to refresh memory?
AFAIK Memotech (and Sinclair?) ram packs have their own refresh counter. And other ram packs often use static ram, which does not need refresh.
Futhermore any usual ram access also does a refresh of the accessed ram columns.

Re: Pascal for ZX81
There is a thread in the German Forum which gives possibilities to use partial Pascal without the need of using tape. It's for 48K RAM only, so not suitable for plain ZXPAND users. https://forum.tlienhard.com/phpBB3/viewtopic.php?t=4076 Meanwhile there is also a solution for "plain ZXPAND users" (3...

Re: Pascal for ZX81
If you have the manual as DOC (MS-Word) or Open Office file, I could do the changes in that document and send it back to you.
Or I could make screenshots of the errors and could add a description, what needs to be done.
