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

Sure every ZII card will work in a ZIII slot (unless it is one of those ZIII Micronics for the A1200, but this is another issue).
No matter how much ZII cards with RAM you add to a ZIII system you still could only add 8 MB max. this way.
The ZII adresspace lies within the adresspace of the ZIII bus and all ZII cards share this adressapce just as if they were in a real ZII bus.
ZII cards aren't a good way to add memory anyway, sice you could only squeze only about 5 MB/s out of ZII (and that is the theoretical value) .That is slower then a hardrive on a turbocard- or ZIII SCSI-controller

Usually RAM on an accelerator and on the A4000 mobo have a higher priority then RAM on a ZII card, so slowdowns will only occur when all the other RAM is used up and the ZII RAM has to be used.
The only ZII SCSI controller where it makes actually sense to have RAM on when installed in a ZIII System is the A2091, as this card makes DMA into ZII RAM. When there is not ZII RAM present it will lead to major slowdowns.
