CSPPC & A3000 desktop?

[x56h34]

Yes, you need the INT2 hack. :-)
It says so in the manual too. ;-)

p.s. the card may not work so well if:

- you are using some devices on the native A3K SCSI chain.
- you have DMAC 4 and Ramsey 7 chips (yes, the newer revisions)

Phase 5 never really tested CSPPC in A3000 units with newer DMAC/Ramsey revisions, but only with the old ones.

Also make sure that you set the jumpers correctly on the A3K motherboard (info available in the manual).

It may be possible to still use the native A3K SCSI, however usually there are conflics between it and the CSPPC card.

Go to http://amiga.serveftp.net for some very clear instructions on how to easily do the INT2 mod.

@Azryl:

Good call, but since he is actually able to boot the system to the early-boot-menu I doubt it that it's the problem.

RAM on the motherboard that's conflicting with the accelerator usually immediately crashes the system after power up.

After you patch everything up it should run great.
Unfortunatly, A3000 requires some work done on it in order to play along nicely with accelerator cards that carry on-board SCSI controllers on them, and usually the SCSI on the accelerator cancels out the A3000 native SCSI.

Installation in A4000 is easier.

Please be extra cereful with all the fitting/refitting of the memory and accelerator card itself in the CPU slot.

I'll try to illustrate how the QUADCLK EXT position looks like (note the angle-sign on the far left as printed on your motherboard):

<=empty-pin 1, empty-pin 2, jumper cap over pins 3 and 4=]

Basically, pins 1 and 2 are the ones closer to the daughterboard connector and pins 3 and 4 are the ones closer to the on-board 68030 CPU.

@Castellen:

Your instructions are simply the best there are. I used your INT2 guide on several A3000 motherboards now, and it makes a much neater job afterwards as the wire distance is considerably shorter than with the "traditional" way of doing it, through one of the CIA chips. Keep up the good work.
