Yep... finally my quest is complete
Lucky you!
When I "got the bug" (about 2 years ago) it was at the beginning of a long dry summer. When a couple of ragged-out F ATs finally came to light, there were about 3 of us that quickly bid them up into the $140+ range. That brought a few more to the market.
Over about 2 months I bought about 3 of them, and finally got a really nice one for about $85. I sold the others at a minor loss and licked my wounds. BTW - I got a halfway decent original IBM box with one of the worse ones, which I kept.
One day I plan to pull it out, do the ANSI mod, add Alt keys and internal Teensy, and keep it for posterity. But that's another day.
