Is the A1200's trapdoor connector classed as a Zorro slot? With busboards it can use Zorro 3 cards like the Picasso-IV in Zorro 2 mode so...

:-?

EDIT: Sorry vlabguy1, didn't mean to hijack your thread, just curious.

:-D

The 150pin connector is basicly ZorroII (Which is little more than a buffered 68000 Bus) with some extra bits and bobs.

Hrrm interesting, wonder if putting a Picasso-IV into an A1200 tower would do it justice (what with it going down to Zorro II mode and no video slot etc).

Not really, running anything on a ZorroII bus is going to hurt.

You'd be better off running a Voodoo on a Mediator.

Another curious thing about the Early Boot Menu is that the PowerUP boards could put CD0: into the list of bootable devices. Usually a CD-ROM would require a CD file system to be loaded first but the Phase5 cards seemed to have this on them ready and notify the Early Menu.

Probably somthing in the PowerUp Autoconfig rom.

Do you think Zorro slot functionality could be determined by those diagnostic programs that Amiga repair centres use?

eh?

Zorro 1 and Zorro II are the same thing (and both are little more than an extension of the 68000 bus). The Power Computing  "Zorro4" was just a custom Zorro II

I don't think the Power Computing boad could actually provide Zorro III as the A1200 simply can't provide the required 32bit signals from the Trapdoor slot.

To diagnose as problem with some Amiga hardware requires quite a bit more than a Zorro II slot. :-)
