Dove Marathon Racer (68020) drivers

Recommended Posts

Well, I finally opened the new SE with an unknown accelerator card. It's a Dove Marathon Racer 68020, which is very nice, with a 68881 FPU.

 

Problem is that I cannot find the drivers. I only found the Dove drivers for the 60830 which don't seem to work (won't recognize the 68020). I will take it apart tomorrow and see if the card is properly set, but would appreciate if anyone could point me towards the drivers, or insight if someone has a similar card. 

 

Thanks,

Pierre

Thanks for the welcome. My first post. I've tried the Dove 030 accelerator CDEV, to no luck. I saw a post in 2003 about drivers for the 68020 in a yahoo group, but it no longer exists (see post at https://www.mail-archive.com/compact.macs@mail.maclaunch.com/msg08453.html).

 

This board is strange. It has four 1MB simms on the accelerator, and the SE board has 4 MB simms, but oddly R35 is still present and the Mac finder shows 2MB only. I would have thought that someone who upgrades the RAM would have removed the resistor to allow 4MB. :huh:

 

Still, board was well seated, without the CDEV, it boots into a 68000 at 8MHZ. Here are some high resolution pics.

Wow, that's interesting, never seen one like that.

Not sure what the chip in the lower right corner with the "PROG" stamp is but if this isn't a PROM that's holding the FPGA configuration you will _need_ a driver to ever get this thing going.

Never seen an accelerator in a Mac yet that would get it's FPGA configured by a piece of software. I know some videocards for the 68000 based compacts do it that way so it's possible.

its serial.

They do support parallel mode too for loading the bitstream.

On one of my Radius videocards the XC2018 loads it's configuration from a part of the EPROM that also holds the declaration/driver.

But you're right, most of the time you see serial configuration ROMs.

Thanks, I tried both Dove accelerators for the 68030, and they do not load (question mark on the CDEV). I'm using system 6.0.7 and 6.0.8, so it should not be a system issue. Without the 68020 application, you're right, it won't work.

 

I also realize how dusty the boards were in the pictures, I will try to get cleaner pictures later today.

Just a PAL, so you will need a driver that belongs to exactly that card to get it to run.

Yep, that's what I understood. Seems that I found only one reference for a driver, see enclosed. I tried to access the older groups, to no help. The drivers in the vintage macdrivers website are both Dove 030, which don't load.

I can't help with locating the driver, but it was neat seing the old LEM list message and Gamba's website here. Spent a lot of time with both back around Y2K; good times. I hope Gamba is looking down from a work station in the sky and having fun tinkering with an old Mac to make it do something it really never should be able to.

 

I'll keep an eye out for it; I just checked UMich's archive to no avail.
