One little
nasty. The 1771 has a basic ability to do data seperation.
I havent' looked at a tarbel board in a very long time but I do hope
that they didn't do the TRS80 save a buck trick and try to use that
internal seperator, it does NOT work. It has zero jitter tolerence.
Strange. I used an unmodified TRS-80 Model 1 EI for years and never had
any problems with the disk side of things. And that used the internal
data separateor of the 1771 IIRC.
If that is the case, why would the Tarbell have so many extra
chips? Also, at the time the tarbell was manufactured, would they
have even known that there was an issue with the 1771's data separation?
Just wondering why...I'm not trying to second guess anyone. Just
that if the extra ICs weren't required I can't imagine Tarbell using them???
