- SVR4.0/MP may run on the U6000/55 but has not ever been commercially
- released on that platform. It may run on the U6000/50 and U6000/51 too.
-
- However, I was talking about commercial availability:
-
- 1. Performance may not be adequate on those systems due to the
- limitations of the 80386 speed and the max memory supported by
- the hardware.
-
- 2. It was NEVER tested through product verification or integration
- test for all the various revisions and versions of U6000/50/51/55
- systems, including the various stepping 80386 CPU chips / erratas
- or the various I/O board versions etc.
-
- 3. The SJ software library is the same as the SLC one, they move
- stuff electronically between the two.
-
- 4. Earlier versions of SVR4 than the one RELEASED on the U6000/60
- ran on U6000/50/51/55 too, but major functionality was missing,
- such as UPS port control, ECOM port control and ECC memory
- board support.
-
- 5. Don't trust it. What may have been used for a special for you,
- is not what commercial customers will have available.
-
- 6. Outside of specials for some internal use folks, it is not a supported
- product combination.
-
- 7. Such a combination is not licenced by Unisys.
-
- 8. It is not orderable on U6000/50/51/55 platforms.
-
- 9. Some U6000/50/51/55 vintage systems use 60MB QIC-24 tape
- drives and the distribution media is 150MB QIC-150 tapes!
-
- Currently the supported platforms for SVR4.0/MP
- are (as of current SVR4.0/MP 1.1 release):
-
- U6000/15 (80486DX 33MHz)
- U6000/35 (80486DX 33MHz and 80486DX-2 66MHz)
- U6000/60 (80486DX 25MHz)
- U6000/65 (80486DX 33MHz)
- U6000/65 (80486DX 50MHz)
-
- So, in conclusion, yes many releases may kind-of-run on the early
- U6000/50/51/55 systems, none are are commercially released and
- available to customers.
