Thanks to DavidC for finding another, but smaller, stash of System-80 tapes and making them available to be recorded. They came as a variety of C-90 Tapes containing up to 8 games recorded on each side. Each side was played in a dedicated cassette player and captured using Goldwave running in Windows 11. Each side was recorded at 44.1khz and saved as stereo 16bit WAV files. Each file was then separated from the large file and saved as a mono WAV file. The tapes were in varying conditions from poor to good. Each file was then loaded into MAME and/or TRS32 emulators but there were very few that would load error free, so soon gave up on that.
Apart from WAV files, CAS files were also needed (for emulators & some physical players and are substantially smaller) so the WAV files were loaded into WAV2CAS and if the status flag came up OK, they were then saved as a CAS file. PLAYCAS was then used to save the CAS file back to a working WAV file at 11khz 8bit mono (default settings) as square wave WAV files. About 80% successful recovery was done using this method. The WAV files have all been tested to loaded without error into MAME emulator setup as a System-80. All are SYSTEM files also. The WAV files can be written back to a Cassette so they can used in a real System-80 and the CAS files used in emulators like MAME. Remember, System files can only be loaded in via the built-in cassette unit unless you have done the mod to switch it to the back DIN plug.
There was one original tape and one case insert also included. Both scanned and included here.
There were many duplicate files as recovered in the original tape stash (see https://microbeetechnology.com.au/forum/thread-735.html ) but there were another 9 files successfully recovered. The WAV and CAS files of each are contained in each ZIP file.
So in the Vintage Repository in the System-80\Software\Tapes folder we placed
adv_adventureland.zip
checkers80.zip
duplik.zip
keyword_utility.zip
micro_grand_prix.zip
out_house.zip
