I have one of these. Great little computers!

Back in the 80's, I wanted one of these computers to write and carry around manufacturing related programs. Was too much money, so I settled on the PC-6. Pocket computer with 2K RAM, just enough!

I would have done more with the Model 100!

There is a 64 character driver floating around that I have lost track of. If you find it, it makes the display more dense, better.
