I don't think I've ever thrown away a working and/or interesting Mac, so I doubt this one would be any different. Especially knowing now that it may be a somewhat odd or special setup. The only thing that makes me wonder is I'm 99% sure it was still a 68030, but the Tokamac upgrades look to be 68040 upgrades. Next time I'm over there I'll pull it out and take a look at it. I don't remember which if any wires were left on (I was somewhat young when I got it... I made quite a mess of it trying to fix it). I don't know that I have the equipment to read a GAL, but I do have something that might work. I'll drop an update once I get a chance to figure it out. I don't even remember where I got the IIfx from originally. Probably eBay.
