Recovering tape files #1

Open nippur72 opened 5 years ago

nippur72 commented 5 years ago

I have about 2.25 hours length of Laser 310 data tape. They are Demo, Utilities, Games, Basic program I wrote etc. I would like to convert them to vz files. Giving they are 30 years old, the recorder I used back then was not a standard data recorder, there is only a little hope.

If you want, I can try to recover them, I know the Laser tape format quite well and if necessary I can apply some DSP techniques I have developed over time.

All my tapes have been transferred to computer in 48/96Khz wav format. I tested one tape with a Sharp CE-152 cassette player. I can get most of them loaded into Laser310 computer, they problem is how to get Laser310 talk to a modern PC.

You can load the files in the emulator and from there you can save them in .VZ format. There are also WAV converters that can be run from the command line.

Anyway if you have files you are not able to load on the Laser I can give them a try if you want.

Thanks for offering, Are you interested in Laser310 software or games? Finally, I got some time I can get back to this project.

nothing in particular, I'm just interested in the machine as I'm going to write an emulator for it. I'm also interested in Laser 500 which is the other Laser computer I used back in the '80s. (The tape format is almost the same, that's why I know it so well).

P.S. by looking at the pictures in the repo, I just learned how to add labels in Audacity 😄
