when you are trying to revive an IBM 5150, that :
- you do not have a single AT powersupply in the house, just 20 ATX PS
- do not have a single PC compatible keyboard, but 10 AT & 10 PS2 keyboards
- at least 50% of your MFM drives have passed away in their sleep.
- you don't remember which is the last DOS version that runs on a standard 5150
Time to grow up I guess.
