structural
test sytem. I's equiped with DECcassete drive (it looks like
normal audio cassete).
Is there any replacement for them ? I mean using good audio casset or
so.
Replacement for which, the media, or the whole drive?
DEC claimed that you couldn't use regular audio cassettes with the TU60
because they couldn't handle the high tension used by the drive. Sounds like
it could be hype but you never know. I mean, what's the point of building a
peripheral that uses regular audio cassettes, except that it *doesn't* use
regular audio cassettes? Worst of both worlds.
First the recording is not audio it's Phase encoded saturation. Second
the media is very different from audion and used a coated binder. Audio
tape may work but not nearly as well. The file system if used is block
structured.
As for drives, I don't know of any aftermarket
TU60 hardware clone. However,
if you're willing to replace the entire system with a software emulator,
Ersatz-11 includes TU60 emulation, using tape image files for media (the
"full"
version of E11 can also use SCSI tapes as the physical medium for the TU60
but that seems like overkill, I mean how many GB of data do you really need
to store on one emulated ~90 KB cassette? :-) Information is on
www.dbit.com,
and the command you use to create a TU60 drive is "MOUNT CT0: file.tap".
Tu58s are findable and would make a suitable substitute at 256k a cart.
But the OS support may be TU60 specific.
