[comp.os.cpm] z280 hardware problem

fifi@cosmo.UUCP (A.F.Zinser) (09/09/89)

We've still problems... Who has experience driving memory (dram)
in a z280-system using the z280-bus-mode (*not* z80 bus mode)?

thanks in advance, a.zinser

I, too would like to hear about hooking up DRAMS to a Z280.
I currently have one using 128K of static RAM (32Kx8 chips)
in 16-bit z280 mode, with burst mode working on a 5-HHz bus.
I would like to go to a 10-MHz bus, but I would need to use
static-column DRAMs (256Kx4 parts) to get enough speed.

This system currently runs CP/M 3 with a 20 meg SCSI hard disk very well.

If you are thinking of building a Z280 system, get in touch
with me, and I can relate my experiences (and circuit diagrams, etc.)
