        I have an Inmos B008 with a T800-20 as the root transputer. The host
 is a 386/25 with SCSI disk. I compiled the program by Vandana on the 3L
 parallel C. Since the PC has a turbo switch (20Mhz/25Mhz), I ran the test
 several times on each mode and used a software switch to change the memory
 between zeo and one wait state. Below are the results :

                0 wait state            1 wait state

        25 Mhz     7.90 s                  8.81 s

        20 Mhz     9.22 s                 10.28 s

        The results are much worse than what Ken Koontz reported for his B008
 with a B404-3 root and on Logical Systems C. Is the problem with 3L parallel
 C, or with SCSI disk?

        Hoping to hear results from others. I would like to know people with
 experiences on 3L C too.
