Does a GVP A2000-RAM8 MEMORY work in an A4000 with Zorro3 ???

Hi Effy,

the short answer is: don't use 16 bit ZII memory on your A4000 (if you can).

16MB on mobo= PRI +30 Latency 8.1

8MB on ZII= PRI 0 Latency 20.7

2MB ChipRam= PRI -10

Quite ALWAYS, in the 16 bit Ram space= SLOOOOWWWW!!!

Hi Effy,

mistake?

You have done the best choise for your actual system  :-)

The problems are basically 3:

1- you must use the 30 pins SIMMs in groups of four

2- 4 MB 30 pins SIMMs 60 ns are expensive (4 pcs= 50EUR used)

3- you need SB rev11 (for DMA) and A3640 3.1 (or you must change an IC on the CPU board)

Anyway . . .a good board for the SCSI II DMA controller too :-)

Ciao
