A3000 - Cyberstorm MkIII problems

[alexh]

I *think* the CS MKIII requires different motherboard jumpers to the CS MKII?

"For the operation of the CYBERSTORM MKIII in the AMIGA 3000 three jumpers on the A3000 mainboard must be set as follows: Jumper (J102)BRDCLK to position EXT, jumper (J104)CPUCLK to position INT, and jumper (J100)QUADCLK to position EXT."

I know that not all of the cyberstorm 060 cards use the same jumper settings, check them out.

He's put in his first post that his A3k already HAS the INT2 mod!

Be careful when changing chips over. I think the Buster is a PLCC chip and the plastic that makes up the sockets gets brittle with age. ALWAYS use a real PLCC extractor tool (costs a few bucks).

he other jumper (CPUCLK) is INT for both cards

Yes

Seems to me that they changed the whole design

I'm sure they had to for the Dual CPU / 233MHz clock rates.

Apparently the SCSI on the MKIII has to be terminated whether you are using it or not.

If you need anyone to test it independantly

If I were you, I would remove EVERYTHING except the accelerator.

Take out all the Zorro cards, all the hard drives, all the motherboard fast ram (as someone here said).

See if you can get it to boot to the KS screen. From there try and get some diagnostics on what version firmware it's got etc.
