Micronik Zorroboard A500 + Blizzard 2040

[lillPiP]

Hi!

I have a Micronik Zorroboard to the Amiga 500.
My problemis with the CPU.
When installing a Blizzard 2040 I won't get the computer to boot (It's recently been repaired).
But if  I remove the Blizzard 2040 the computer will boot and I can enter the Early Startup and here I can see both the Buddha IDE and my Picasso II+ cards.
Is there any jumpers on the Blizzard 2040 or the Micronikboard I have to change?

Kind regards
//Peter

I hope this isn't a silly response, but have you tested the accelerator in an A2000?


P.S. Where did you find the Micronik A500 busboard?

"... Where did you find the Micronik A500 busboard?"

Was thinking the exact same thing... 8-)

Well, on a danish amiga-advert site  :-D

Nope I hasn't tested the Blizzard in a A2000 since I got it repaired from France 2 days ago! And it worked in his A2000.

I had to do nothing special with my  B2060 when installing on my Micronik busboard to get it to work. I have 3.1 Rom and 2.05 on a switcher, nothing on Micronik's sockets.

@ lillPiP



The  A2040 is designed to go in the processor slot of
an A2000.

Now the Zorro 2 slots in the A2000 and on your A500 do not
carry all the nescesary signals to reqired by a processor card.

However they can be modified to do so, so I suggest you
look at the pin configurations of the slots and add the required to your Zorro slots.

Not true, the Micronik bus board does have a CPU fast slot.

Do you still have the 68000-processor installed? I have tried with and without it but this didn't do the trick.
I have 3.1 rom installed. The Micronikboard should be OK, since it shows the other cards installed in the board when I enter the Early Startup menu.

Yes. I'll check if the busboard manual has some info. My A500 is rev. 6 and has ECS Denise changed, 2 MB Chip by Megachip 2 (0.5 in the internal expansion slot)- so the mobo has been rejumpered. Does your computer boot when <2> pressed to disable Blizzard?

[lillPiP]

For the moment I don't have the right keyboard here with me.
My A500+ is a rev.8A.
It really boots up fine without the Blizzard. (The BLizzard should be OK since it's newly repaired.)

[zipper]

Rev. 8A should work without any tweaks with the busboard, it's the only rev. that supplies the 7 MHz clock to the expansion port, which may be necessary for some CPU cards; no idea if Blizzard needs it. Functionally my A500 and your A500+ should be similar after the tweaks I've done (!?).
The disable key is 0 (zero) - I mixed it with A1200 Blizzards
Are you sure to have the Blizzard librarys installed - the only idea that popped into me.

ps. - Blizzard seems to have clock jumpers cclock and eclock, open by default. Perhaps they could be closed for test. Maprom and SCSI jumpers should not affect to the booot process, if you don't have other expansions in the tower.
