I picked up a non-working Mac SE from a local woman. I believe the power supply is likely bad but haven't gotten around to testing the voltages yet.
However, when I took it apart to assess the state of the analog and main boards (worried about the PRAM battery leakage), I realized this machine has a 68030 accelerator plugged into the PDS slot - labelled as the PerformerPro by Harris International, Ltd. It appears to be a 25MHz processor and has some empty sockets for other chips, assuming an FPU. Not sure what the second one would be for.
Anyone have any information on this? I couldn't find anything on Google, and the closest I could find was the MicroMac Performer/PerformerPro devices, which appear to behave the same, but definitely look different and obviously a different manufacturer.
I actually have a functioning SE that has a working power supply and analog board, so I decided to see if the main board / RAM still worked. Fortunately, it booted right up with my SCSI2SD plugged into it.
Everything seems to be in working order, and I'm planning on pulling it to give it a thorough cleaning, but wanted to ask about these PDS accelerator cards. As best I can tell, they seem to require a system extension to take advantage of the CPU on it, but I could be mistaken. When running the SE, the LED2 (amber) is lit up, but not the LED1 (green). I have not idea what either means. Is there a way in Mac OS 6 / 7 to get CPU information. And if so, would that software even recognize the accelerator? It really seems like this card should make my SE closer in performance to an SE/30, which would be great.
Any advice / help would be greatly appreciated.
