Re: HELP WANTED: ZX81 "lost" files

Hi,

:shock:

What about a CRC for each "p" file !

… using "ZxCollectorv.1.00" … for example. (VB5 DLL- Same "Xur"'s DLL)

Re: Memotext & word processing in general

:D Yes, i had to compare the original zeddy's rom and the IF mirrored rom ! The IF routine seem to be copy in the low 8K rom (Printer routine room). The rom "peek" ($880) seem to target to $2880.. :shock: When you type LPRINT, the old "printer routine" isn't read, but the $2880 ($x880) is executed i...

Re: Memotext & word processing in general

Hi Paul, I plan to add the Memotech Centronics to the Xur… Is it possible to save the ZX81 $0-$2000 (the ZX81 rom) using a I/F card ? I had to compare the hard memory relocation. In fact, the IF card redirect the RD value form the "PRINTER" ROM routine, and mirror this memory room. I had to retrieve...

Re: [Vb81] Test release.

Hi Greg, New release available on the http://zx81.vb81.free.fr web site (r.18-08-19). The text number floating point retrieved, seem to be fixed.

Re: [Vb81] Test release.

Ok… It's due to a bad "text to P" floating point error on the "128" value conversion. "128" text value is ok in the basic program, but the encoded value "128xxxxxxx" is wrong. 10 LET P=128 20 PRINT P Will be wrong too. We had to get the string value to avoid this error : 10 LET P=VAL"128" 20 PRINT P...
