I recently got a PL143 Accelerator-card. It was in the LC-PDS of a Macintosh LCII. There is a 68030 and a 68882 @ 33 MHz on it. The card get's pretty hot, but processor and 68882 don't work. I need a system-extension or controlfield to activate the card.

Formac service has no driver for it and googling for a driver didn't help. The LC II came without driver.




On the board it says:
Quote:
formac PL143 Rev 1.0 04.03.1993 HV L6

There is a number on a small silver label: 72 289
Maybe the card has another name, but that's everything I know about this card.

Is there anyone who has a driver / extension / control for this card?

Thank you for every hint!

Uwe Fritz

Dear AlterMac,

I have a Formac - LC III PRO 50 Accelerator Card with the same Motorola Processor. Maybe the driver will work for your Card too ? I can send you an Image of this Software if you like to test it.

For other drivers go to:

The Macintosh Driver Museum at:

Formac Pro50 LCIII Accelerator Card
maybe you can use it for your card.
No guarantee... please use it on your own risk.

Thank you.

The System extension works with Accelerator-Card and identifies the card as PRO 33 LC. It works with MacOS 7.1, but with 7.0.1 my LC II didn't boot after switching to the new processor.

A little shock for me: When I switched the processor to the acceleratorcard and pulled the accelerator, the LC II did not boot with the onboard processor. Simple solution: Reseat the accelerator and it will boot with the accelerated processor.

Integer-Benchmark: + 85%
Floatingpoint: +40% (Tattletech says "NO FPU"?)

Maybe it works better with an LC. I will test this later this week.

Thank you for that very rare extension.

Uwe
