Hi!
I've got some problems with our A3000's and the SCRAM. I used
SetRamsey to test the following computers:
- 5 A3000/25-40 bought at the beginning of july 1990 here in germany.
4 of them have a revision 6.3 board
1 has got a new 9.X board (The old one was broken after 2 Months)
- All 5 are equipped with 4MB SCRAM (32x44258 each)
We bought the RAM in one bunch from one source
Result:
- GOOD: If you switch on the SC Mode, you get 10%-20% perfomance increase
- BAD: While in SC Mode, the SCSI controller chip on the old 6.3 board can't
access the RAM anymore. On the 9.X board it DOES function!
Can anyboday at Commodore (Dave, Randell) verify this? Can I upgrade the
old boards?
Stefan
BTW.: The SCRAM is OK, so it must be the board!
