Problem with Viper 030@28mhz accelerator board
« on: December 24, 2010, 10:08:36 PM »
I just recently walked past a dump, where in the corner of my eye I spotted something that looked like a huge keyboard. I went to take a closer look, and found out that it was an Amiga 1200 with a 030 accellerator board and scala dongle. Jackpot!

So anyway; I dried it, cleaned it, it works, but the floppy was not powering on and same with the harddrive. I am using an old Amiga 1200 PSU that was making some strange high pitch noise when I tried to boot the amiga with the harddrive installed in it. I removed the harddrive and it booted fine with the PSU not emitting any detectable noise. However, when I have the 030 installed it sometimes reboots and shows a red "Software Error" screen. I tried removing the memory on the board, same effect. Sometimes it does not boot at all, just gives a black screen. Someone suggested the card had problems with 3.1 roms, but this amiga has only 3.0 roms installed.

Does anyone have any apparent theories as to why it seems unstable? I don't have any other Amiga parts to cross-swap with to test a lot of things, so I'd really appreciate some sound input here so I'd know what to look for in order to try fix it.

And merry Christmas everyone :]

I am not convinced, I know several folks running 030s AND harddrives on vanilla A1200s, and this 030 is only running at 28mhz. However, valid point, something to try. Any other suggestions though while I look for a new psu?

Ah, thank you Franko. Brilliant that you could reproduce the problem. I am definitely more convinced now. Will find a psu solution somehow.

Well it doesnt boot when the harddrive is plugged in, so I'd assume not. On the other hand, it seems the root issue could be the psu. I'll give it a go with a 500 one if I can get my hands on one.
