I just got a really cool mac plus, and its got some sort of accelerator in iit. It also has some sort of port in the battery bay. I cant id the accelerator because the accelerator card is making the motherboard stuck. Any suggestions as to getting it out would be helpful. Also whoever put the accelerator put some sort of metal shield in along with an internal fan. I will post pics as soon as i can.

The Radius Accelerator?

That'd be great if you could post images...

DB-25 SCSI connectors in the battery bay were very common.

Dove MacSNAP

A few pics of my own 512K with RAM and SCSI expansion. See http://www.mandrake.demon.co.uk/Apple/macsnap.html

To remove your logic board plus add-on board, the trick is to use gentle force on the guide rails. A standard logic board just slides in on the guide rails. Tall add-on boards require that you use thumb pressure to widen the (lateral) gap between the guide rails so that the logic board falls out. Easier to do than to describe. The steel chassis is sufficiently robust that you can perform this operation many times without causing permanent damage.

When the logic board is out, I'd be interested to hear which add-on board is installed.

Is it a Brainstorm? Or it could be a Dove Marathon.

I finally got it apart, and its a mercury 030 plus accelerator. Im not sure, but i think its the same as the micromac performer, so ill try the drivers. any documentation would be greatly appreciated! It also has a ram expansion card attached to it. not bad for $1!

So is it a mac plus with an u

So is it a mac plus with an upgrade or a 512k? I'd be odd if it's a mac plus as that already has scsi.

eep

I wouldn't go plugging any SCSI (or other) devices into that port until you find out what it is. Is there an Apple System Profiler or some equivalent 3rd party app which will give you a system rundown? Tattletech?
