I had one of those and it was one of the best comps I’ve ever used. I could kick myself for getting rid of it.
You can pick one up cheap, under $100. There are lots of followers and users of those antiques. You can buy a modern plug-in card that uses compact-flash cards and USB sticks (CFFA3000), and download thousands of programs free off the Internet loaded onto a card or USB stick. Practically every program and game made for the IIe is available. I'm using this setup on my 1977 II and it works great.
