Blizzard 1230 issues

Hi, I recently bought a Blizzard 1230 MK IV and now having several issues leading me to think the Blizzard is bad. First of all I have tried several ram sticks (EDO and FPM), swapped the CPU, used a different power supply and same issues.

When the machine turns on it will start booting and then a Guru software error, then if I reset several times it will get into WB but give Set patch failed or DFO failed or disk is unreadable message. If I keep reseting it will boot and then work great, its almost like it needs to warm up.. Any thoughts

Enter the Early StartUp Menu on your A1200 and check if the board is working under Diagnosis (something like that, I don't remember).

Also ensure that you have plugged the Blizzard firmly, and check the board without any RAM at all.

Did you check the jumpers for the extra RAM?

Board appears fine in teh early startup menu.

Set jumpers to both 60 and 70ns.. same issue

Map rom or no map rom... same issue

Again when it finally boots it works fine. When I was runninf AIBB I did see some screen corruption when running the memory benchmark

PSU failing, caps on Blizzard, bad solder joints etc.

Same routine for every bad board unless there's a *hard* fault not intermittant

I did try another PSU so definitely not that. I will borrow another A1200 to rule out my machine

What kind of PSU are you using? 2.5, 3 och 4.5 ampere @ 5 Volt?

Have you tried the Blizzard without any memory at all?
