Even more Microbee Tapes have been recovered

[ChickenMan]

Thanks to g67wjjk for providing recordings of another 3 Microbee tapes and scans of the cassette labels and inserts. Tapes were recorded at 44.1khz and saved as stereo 16bit WAV files. The Left & Right channels were separated and saved as individual mono files. Once the recordings would load error free, they were down-sampled to 22khz and saved as 8bit WAV files to reduce their size considerably but still remain loadable.

None of the recordings were able to load into a PC85 Microbee without an error originally. But all that was needed was to apply a de-noise filter that then produced error free loading versions. The WAV pattern of Missile Wars is very variable, somewhat crazy, but after noise removal I was surprised it loaded error free.  It could not be down-sampled though, only saved as an 8bit WAV file for reliable loading. The 3 games are already in our floppy disk collection.

Also provided were quality scans of the cassette insert and the cassette label.  We already had Missile Wars cassette label but is replaced here with a much better quality version.

So in the MbeeTech Repository in the Microbee/Software/Tapes/Original folder we placed

artillery.wav
battleships.wav
missile_wars.wav
