Recently bought a Mk1 Cyberstorm 060/50 for my A4k but it doesn't seem to work. Wondering if it's faulty of I've missed something?
Amiga 4000 RevB ,Kickstart 3.1 / Cyberstorm Mk1 060/50, 96mb (2 x 32, 2x16)
The A4k is running on a A3640@33mhz so jumpers 100 and 104 under the cpu are already set to external.
All I get is a black screen, constant HDD LED , no floppy click and no early boot up with mouse buttons held. I have stripped the machine down to just motherboard,cyberstorm and floppy but get the same result.
If I plug my A3640 back in it fires straight up, it also works fine with it's original 030 (jumpers moved of course)
I have reseated all the parts of the cyberstorm and checked the jumpers are in the factory positions. I have also tried it without its memory tower and just having J100 set to ext.
Is there anything I've possibly missed or is the card dead?
Thanks in advance.
