- Well, Morgan was looking for security (if I may speak for the guy :) and
- dealing directly with teh 8530 can lead to serious problems...it must have been
- tough enough to deal with ProDOS 8 and having to support the //e...I mean look
- at what Morgan had to work with! Although, initially, I was not happy with the
- lower throughput, it was a drastic improvement on what we once had for ProLine
- and I can't fault Morgan for "doing the right thing"(tm) - as you can see, CTS
- integrity has been compromised by dealing directly w/ the 8530 -- the question
- still remains, however, whether or not the problem can be corrected while still
- dealing directly with the chip.
