I have some old Commodore 64 tapes from 1985 that are in rather bad condition.
Few of the standard format programs can be loaded correctly, and it is
hopeless to try to load any of the programs that are in the 64'er Turbo Tape
format.
Last December, I tried archiving these tapes with a modified 1530, where I
rewired the internal card edge connector, so that a C2N232 device could be
plugged in. Tonight, I tried reading a couple of tapes with Andreas
Andersson's TAPir program, which samples the audio from a sound card. It
didn't produce better dumps than those I already have.
Are there any robust tape decoder tools that apply some sort of a search
algorithm in order to read almost-unreadable tapes? Do they require a
loopback to the pulse detection algorithm, or can they work on pulse streams
(TAP format)?
