Connecting other things to the Blizzard SCSI connector?
« on: April 01, 2006, 08:46:31 PM »
I fitted a SCSI kit to my Blizzard 1260 today, and it got me wondering whether the SCSI connector could be used for anything else, like a graphics card? Or is the connector only usable as a SCSI bus? Anyone know any technical details of the SCSI connector on the Blizzard?

Well I didn't know whether the bus that the SCSI interface connects to is just a SCSI bus, or some kind of ISA or PCI interface which could be expanded. Looks like no. Oh well at least we have PCI slots now :-)

Actually, the connector on the Blizzard is a DMA-enabled interface that doesn't have anything to do with SCSI in its own right. It's the add-on card that gives the SCSI ability - so theoretically it should be possible to design a card that fits the connector and bungs data to the Amiga via DMA.

That's what I thought :eureka:

I guess nobody's gonna invest in this though now we have PCI solutions. Though Mediator and Prometheus don't support DMA do they? I wonder whether the Blizzard expansion connector is a wide enough bus for PCI with DMA?

Well I thought I would give it a try, so I soldered a ribbon cable from my Voodoo to the SCSI connector on my 1260. It didn't work.







Just kidding.

Heh, well up until my previous post about soldering my Voodoo to my Blizzard, I was dead serious. Nothing wrong with a bit of humour about it though.

But yes, quite  :horse:
