Re: [Type_ins] Fun Program from EMI cassette tape
Aside from the surprising elegant and compact BASIC program, the entire J-card is interesting with many helpful tidbits. Back in the day I might have not even read this card info, but the 8bit Show & Tell has pointed it all out. Good video THORN EMI EMITAPE Computer Cassette C20 Use to record (SAVE)...

Re: ZX80/ZX81 with a 6502 ...
I was replying to this thread which said the Z80 was superior for supporting DRAM refresh. But did the ZX81 make use of that feature? ZX81 did not use DRAM, only the add-on memory packs used DRAM

Re: ZX80/ZX81 with a 6502 ...
Great posts, very interesting information!
One question, doesn't the 16K RAM PAK have its own refresh circuit?

Using standard PC keyboard with ZX81
Has this been discussed before?
Seems like we could use an Arduino or Nano Pi to read a USB/Bluetooth or PS/2 keyboard and generate the correct signals for the 9 pins of the ZX81 keyboard connector. I have sooo many spare keyboards ...

Later release: ... - Off screen D_file destruction avoid at the right and the left sides. ... You have a great fix, which I was struggling to implement -- i only had IF G$="4" THEN GOTO 2050.

Re: A 15.999K Adventure game: The Valley of adventure.
R-2 uses extra bytes and time might as well use 21. 23 would work if there's a POKE 16418,0 somewhere, I'll have to check. Ah, I see you are correct: 250 POKE 16418,0 This is DF_SZ : The number of lines (including one blank line) in the lower part of the screen. Changing it to zero allows one to PR...

Re: A 15.999K Adventure game: The Valley of adventure.
Code: Select all
537 PRINT AT R,K;G$
R is the constant for 23, which is not valid for a PRINT AT statement. This modification appears to work:
Code: Select all
537 PRINT AT R-2,K;G$
