Maybe that's why the current bug list was published in Byte...  Current
32032's (rev N) do not need 'lots of hacks' -- 'last I heard', in your case,
must have been when they were producing rev K chips, at which time 68020's
were not in general supply.  And Tek, as a National customer, has complete
access to Nati bug lists.  Who have you been talking to?  Better get a new
source!

I guess you don't talk too loud, except when posting rumors you can't back up!
There are several around here -- they push about 1250 dhrystones, which is
faster than any 68000.

I won't suggest the 32032 is going to take the world by storm.  The 68020 is
obviously faster.  (Doesn't it also cost about 3-4 times what the 32032 does?)
But John was indulging in exaggeration and rumor that begged rebuttal.
