We have had a Codata 3300 in house for evaluation for the last 1 1/2 weeks,
with 750 Kb ram, 30 Mb disk.

In terms of cpu speed (Zilog benchmarks), it was found to be comparable to
a Vax 11/750.  In terms of disk throughput, it is approximately 1/3 the speed.

Several problems identified were:
1)  Codata's uucp (as delivered by Unisoft) will not talk to Berkeley uucp.
    Apparently the problem is a non-portable checksum evaluation.
    Codata is supposed to be fixing the problem in 2-6 months.  Until then,
    their machines will only talk to each other.

2)  Porting V7 uucp to the Codata allows the two machines to handshake,
    but file transfers fail, because raw mode does not disable xon/xoff.
    Apparently the problem is in the intelligent serial i/o card, and is
    supposed to be corrected in 3-4 weeks by substitution of a new card.

3)  A source license for the Codata is $10,000, if you already have a Unix
    source license.  In our case, this would boost the system price from
    $18,000 Canadian to $30,000 Canadian.

For the record, the Codata timings were:

piper:		0:11.0		 0.0		 4.4
proc_call:	0:44.0		43.6		 0.1
sieve:		0:08.0		 7.4		 0.1
