I would be interested in the XT motherboards. Mike Rosen Sent from: My extremely complicated, hand held electronic device.

I have to search for my Hercule Video Card. Not sure where that is. I have found my other PT68K-2 with Humbug/OS9 roms. I'll need to replace the 48T08 chips or just drop in 6116 (100 ns) so I can start playing. The PT68K-2 is in an AT case with an AT Power Supply. It must weigh at least 40 pounds. If the floppy drives are belt driven then they're useless but I think this is when the first pancake drives arrived. This system has a 720K 5 1/4 & a 720K 3 1/2.
Anyone know the best way to resurrect an old hard drive that hasn't run in at least 30 years?
What I didn't find my other 6809 boards or my parts for building those 35 year old boards. I have them somewhere.
