Three of 'em:
- Model 25 Color - fully functional afaik, turns on, shows disk and arrow, etc.
- Model 55SX - fully functional, needs RTC unit battery replaced or entire unit replaced, then needs reference disk.
- Model 75(?) - fully functional, needs new CMOS battery in RTC unit or unit replaced, then needs reference disk.
The Model 25 is the first revision, according to IBMMuseum, because it has the power socket and the video out jack in line on the vertical axis. It will come without HDD unless that's a deciding factor or will raise value - HDD is functional and has controller card, is a 3.5" MFM w/ 8-bitr ISA - I'd rather keep it, but again, if it makes a difference.
The model 55SX has all original parts in place, no caveats - nice machine.
The model 75(?) has some damage to a few faceplates, but they will all still sit and stay in their correct spots (connectors on the sides of some damaged/broken. I was an idiot when I tried to take it apart years ago. Comes with all original parts, slight rust damage on sockets in the back, IBM logo in the front missing, but present w/ model number in the back.
Cost: Make an offer + whatever it takes to ship.
I can't do jack with PS/2 machines, I've discovered, between MCA, reference disks not being easily available anymore, and their strange proprietary architecture alltogether, so I've decided to sell them to whoever CAN make good use of them.
