Is this a ZX81 recording or not?

Will,

this loss of quality can also be explained if the tape is reversed ... is it brilliant or dull ?
The readable face is the dull one.
The brillant face will give a loud signal.

Hi Friends,

I bought a new USB audio interface and tried to do a recapture of a few of my Dad's tapes that had noise, and the results are much better than before. I wanted to look at the tapes you were interested in that were described as GM Save, which you thought might be a varient of RLL's cassette tools.

One of the tapes that I thought might be relevant was one labelled GMSave (I'm calling tape 14) and I have now been able to get off the .p programmes and the audio is pretty clean. However I don't know how to get EightyOne to run the basic loader and then move on to 'listen' to the fastload segments - next step is to wire up the real ZX81. I've uploaded the audio from both sides of the tape at the link below. Does this give anything useful? I think Side A is just some sort of graphics routines, but Side B is the GM Save stuff. I don't think there a copy of the save software unfortunately, but it does look like RLL's. Program1 had a different title 'Bwlchyddar Fastsave', that's actually the name of the house I grew up in so I don't know what my dad was doing with that one!

Best wishes, Will

That's great, thanks. I'll examine the GMSave side of the tape when I get a bit of free time. With it having multiple names, I wonder whether is was a type-in routine from a magazine that's been customised...

The Fast-Load program is on the "3.wav" !
Thanks Will.

USAGE:

Set the RAM_TOP :
POKE 16388,0
POKE 16389,123
NEW

LOAD"FASTBAUD"
NEW
RAND USR 32384

(press "space" to return to the Basic monitor after a LOAD command.)

Have Fun !

Thanks both, I'll have a tinker tonight to see what you've found. Cheers

Thanks Xavier, I've given all that a shot and saved with the tape backups I've been making

willinliv · Post by **willinliv** » Thu Nov 12, 2020 11:45 pm

Another recapture of a tape that looks something related to GM Save. This is one I tried to capture earlier, but again new USB audio capture device, and some noise reduction of the machine whirr. On side B is I think the interesting stuff. I still don't know what I'm doing to load any of the fastbaud stuff but the basic programmes looked interesting:

(from 2.2p)

2.2.p: (3.01 KiB) Downloaded 186 times

Link to files on this tape '18_ACS compilers' in case of interest: https://drive.google.com/drive/folders/ ... sp=sharing

I cut b.wav into four parts but i think part 3 (3.wav) is junk
