A complete WAV file of the whole cassette is now provided in the shared folder linked above (about 10 minutes, 46 Mb). Warning: I could not load the program(s) on the real VIC, as it gives load error even with a good datassette. Bad sign. See if you can sort it out.
Thanks a bunch!
Be sure to record back to tape with full-blast, nuclear meltdown red area.
Tried to build audio2tap on Linux but it's broken. So some Windoze user has to give it a try.
I tried with the old (DOS based) tape64, with no success. Apparently, it does find something when you use the inverted waveform - whatever it means . Didn't try with wav2prg because some dll files are "missing or wrong" (?).
Is there a way to play wav files directly into the vice emulator?
Have you tried fiddling with parameters (VIC 20 clock, inverted waveform, speed, etc.)? Sorry I can't help more, will do another record with louder volume - avoiding distorted sounds - and changing my Walkman's batteries.
I think wav-prg isn't up to it. The recording looks OK – just what I've seen from a bunch of other ancient tapes which load without errors. No need to invert anything.
In the original folder, you can find the "right" wav file (16 bit mono, normalized) and the corresponding TAP file obtained via AudioTAP 2.2.1, normal waveform, VIC-20 PAL clock, sensitivity 60. I tested it OK up until the "set up" file, as stated in the initial Training section of the manual (screenshot attached). If someone wants to test it thoroughly, I'd be grateful. Also, maybe a disk version would be welcome, but I understand it would be quite hard to convert.
Have fun, as far as "fun" is the right word for a stock control program .
Yep that's the behavior loading the first file in the tape. You should follow the training section of the manual: first load"set up",1,1 with the space between "set" and "up". It will skip several minutes and two files. Then the prompt in the screenshot appears. I guess you have to setup your database before anything else, don't know why the setup was put as last file of the series.
Anyway, this is the only working tap file so far, so much for now.
Oh, in vice I use full blocks, but I guess 16k would suffice.
Must say, it's a bit more primitive than I expected even for the Vic. Having to have the descriptions separate from the price etc in memory is a real pain.
They should have made it disk based.
Anyway, good job preserving it. Are you going to upload it to zimmers etc?
