I've just taken possession (been possessed by?) two Mitsubishi X-86
I've spent some time with the limited manuals that I have that came
with them and also searching the AES Electronic Library for related papers.
It seems that the ProDigi (PD) format was developed in the mid-1980s
while the original machines were developed in the late 1970s.
I _believe_ that the X-80 was the earlier format and the X-86
represented the later format (it indeed says "ProDigi" on it).
There is one empty card slot in each machine, but from the
information that I have, that is the serial AES/EBU interface and
this will force me to transfer tapes through the analog domain which
is not the end of the world, although I worry about the
Digital-to-Analog converters in the X-86 -- I don't really worry that
much about my RME Multifaces.
I have seen in some of the AES literature references to the X80/86
format, which, to me, would imply some compatibility.
So, at the moment, the big question is:
If I have to transfer a tape that was made in 1982 on a Mitsubishi
machine, will it (theoretically) play on my X86s?
The other underlying questions are:
(1) Did they ever implement > 16 bit ADCs/DACs in the machines? A
20-bit was considered a future option. Did it ever get implemented?
(2) If the answer to my big question is NO, was there any
compatibility upgrade to the X-86 that would let it play X-80 tapes?
(3) I have assumed after reading the AES articles that there is
absolutely no interchange between Sony DASH 2-track and the Mitsubishi.
Did I miss anything?
(4) If the answer to the Big Question is NO, do you know of anyone
who can transfer X-80 tapes.
Pohlmann (4th ed) didn't seem to have anything to say about the
ProDigi format--though there is a brief mention of DASH.
Thanks for helping me with my confusion.
