Thread: Exidy Sorcerer II Questions

    It's just called wav2bin, it's out on the web. Not sure if it works with sorcerer files, but it should. I need to try with my old DOS 6.22 box.

    BTW you can download it here: http://pocket.free.fr/html/soft/wav2bin_e.html

    I guess this wav2bin program won't work on the wav files I have. Does anyone know how the .bin files that are out there were created? Maybe Tezza knows?

    No, I don't know how they were created. I have converted a few to WAVs via MESS for my own collection via a convoluted process which I detailed here. https://www.classic-computers.org.nz...re-stockup.htm

    Interesting. Then where did all those .bin files come from? Someone had to make them.

    Good question. The people that wrote the code for the Sorcerer module in MAME/MESS would know. Who these people are though, I have no idea.

    I've tried to find another program that can convert .wav to .bin but I've had no luck. Surely there has to be something out there as lots of old computers use tape files.

    Since a WAV file is nothing more than a sampled audio signal it depends greatly on the type of signal recorded to have a 'wav2bin' program recognize/decode it to binary data.

    It depends on the signal encoding used (like Manchester 1200/2400 Hz) and the baud rate and the number of bits per byte at which it has been recorded.
    So there will be no universal wav2bin program. On the web you will find lots of wav2bin programs specific for a certain type of computer.

    A ZX80, Acorn Atom, Commodore 64 produce totally different audio signals than an Exidy sorcerer

    So it's starting to look like we need a specific wav2bin for the sorcerer then. Well someone obviously figured it out as .bin files exist. Too bad we don't who made them or how.

    The .bin files in MAME were created using a program written in QBASIC on a 386 as a way of storing and transferring programs for Exidy Sorcerer, Super-80, Microbee and VZ-200 which all have a similar tape format (some differences in headers and CRC calculations).

    A serial connection between the Super-80 with a special ROM allowed loading and saving of programs - effectively using the PC as tape drive so the machines could still be used after the tapes had failed.

    Therefore there was no conversion of .wav to .bin - there was a conversion of the serially transferred bytes to .bin happening on the PC.

    The format became incorporated into MESS (now MAME) when the owner of machines it was developed for became a dev.

    I believe the format is deprecated in MAME even as it becomes more popular as an interchange format outside of it.

    Brad Robinson's tapetool2 has recently been updated to support the Sorcerer format. Support for .wav to .bin may not be 100 percent yet - I have not had time to check but it can do many useful things including converting a .wav to vanilla binary (ie no header info or CRC bytes) which is great for feeding to disassembler or for inspection of Sorcerer object code in a hex editor.
