Title: A600 with Apollo A630 Turbo (I think?)
Post by: Bluewizard on March 14, 2025, 06:33:58 PM
I have recently come into possession of an A600 that has needed some work which I am slowly working on.

I have it starting up and see the Kickstart 3.1 boot screen with all colors now..  (Red and Green where not working).

Anyway it came with I think An Apollo Turbo 630 board.  When the board is installed over the 68000 the computer does not boot.
If I remove the board I get the kickstart as expected.

It has a 40 MHz 68030 and a 68882 and what looks like a 4 MB 72 pin SIMM
I have removed the SIMM and opened the RAM jumper with no change. 
I have changed the wait jumper to be on or off again with no change.

The 68030 does not seem to get warm.   Any thoughts?

Thank you
-Ryan

how well is the turbo card seated?

it is absolutely essential the card sits snug and firm on the 68k CPU.

I thought it was until you mentioned this.  I wouldn't be surprised if some pin isn't touching as this has had some other necessary repairs. 

Looks like that will be another challenge once I get the A600 all cleaned and back together. 

I am always happy for other ideas.
