[TUHS] Dhrystone Benchmark (was: Unix on Zilog Z8000?)

[Oliver Lehmann]

Sorry... I hit send to early by mistake... I wanted to include a  
comparison chart...

CPU   MIPS   MIPS
     System                      OS          CPU     (MHz)  V1.1   V2.1  REF
### ---------------------- ------------ ----------- ----- ------ ------ ---
...
316 IBM PC/AT              PCDOS 3.0    80286         6.0    0.39 -----   0
317 ATT PC6300             MSDOS 2.11   8086          8.0    0.39 -----   0
318 Onyx C8002             IS/1 1.1(V7) Z8000         4.0    0.29 -----   0
319 PDP 11/34              UNIX V7M     ----------- -----    0.25 -----   0
...

So WEGA at P8000 is between 317 and 318 - and 318 is the the Onyx  
mentioned as well.... but what is "IS/1 1.1"?

Best Regards,
Oliver
