And yet, even in *this* message, you included 100% of Allison's message
to which you were replying. PLEASE just trim it to the paragraphs you're
actually addressing in your reply, some people are paying per packet to
receive this list and anyway it's a real pain to have to page through
many screens of text trying to find the parts that are new.
All the
while, I've been harping on this notion that there must be SOME drives that
provided this 8-bit option, else it wouldn't have been in the standard at
all.
Well, for that matter, the SCSI-2 standard tells us that wide drives have
the signals spread across *both* a 50- *and* a 68-pin cable. But good luck
finding an actual drive like that. Some standards are obviously the result
of bickering in the committee and are too silly to implement for real.
Similarly, the 8-bit ISA market had shriveled up by the late 80s so it's
certainly understandable that manufacturers building new drives (especially
the really fancy 2.5" portable ones) wouldn't bother with an 8-bit mode.
Who would need it?
Frankly, I wish the current generation XILINX software
would support the
2000 and 3000 series parts, but the former was end-of-lifed some 10 years
ago and the 3000 has been replaced with the 3000-A series and 3100 series.
The 3030 would make my job MUCH simpler, but I just can't use one due to
software incompatibility.
All the more reason to use MSI TTL when it's a good fit (and appropriate to
computers from that era).
