OK, I have had a go at producing a simple tape cleaning program. It does no more than turn the input file into clean square waves. The program is a single C source file, and compiles with gcc on Linux. On Windows it should compile with MinGW or Visual C. The user interface is command line: ./tape_cl...

Claus, I confirm that my version of MEMU will load "Zombie Near" from the WAV file. Bill === memu started at Sat Nov 5 11:48:39 2016 === Cassette remote control start Tape start. Cassette remote control stop Tape stop: CTC Pulses = 3282. Cassette remote control start Tape start. Cassette r...

As those who were at Memofest 2016 know, I have created a version of Andy's MEMU that can load games from audio WAV files. Claus PM'd me about using this to clean up audio recordings. This is possible, but MEMU will probably auto-run the game and so the problem will be breaking into it to save the f...

Absolutely stunned by Andy's Hex-Train. Does he get any time to sleep

Dave's collection of hardware was impressive to see for real, I am sorry I wasn't able to stay long enough to see the video-wall in action.

Many thanks to Nicola and Dave for the hospitality.

Bill.

See you all there

And why use BC at all? How about: #asm psect text global _Curschar global _Fileend ;Init ld hl,(_Fileend) ;p=Fileend ld de,(_Curschar) ; Remember the insert point loop1: dec hl ;p-- ld a,(hl) ;get char to be moved (swap=*p) inc hl ;copy it (p++) ld (hl),a ;..to p (*p=swap) dec hl ld a,h ;have we rea...

The only difference between your two versions that I can see is that the original version will stop after copying *(_Curschar-1) -> *(_Curschar) Whereas your second version will stop after copying (*_Curschar) -> *(_Curschar+1) If, as I understand, you are then going to replace *(_Curschar) by a new...

I think that the way I would do this is something like: ld hl, _fileend ; High address ld de, _Curschar ; Low address and a ; Ensure carry is clear sbc hl, de ; Number of bytes to move ld b, h ; Copy HL to BC ld c, l ld de, _fileend ld h, d ; Copy DE to HL ld l, e dec hl HL points one byte lower ldd...

Dave,

Up to you. It is worthwhile supporting both options in the software anyway.

Bill.

Dave, OK. The point of option 1 is that it could be done with a point to point wire on the back of the keyboard PCB, and does not require a flying lead. Probably neater, although it does require two solder connections to the PCB. Having bought the mid-point off board (option 2), then the obvious thi...
