My Apple ][ "Europlus"

I can't remember when we got the Apple, but it was long ago. I would guess around 1980. A friend of my father imported them from Taiwan or somewhere. Just your standard run-of-the-mill Apple ][ clone.

We started off without floppy drives -- I wrote a "breakout" lookalike in Integer Basic, which I eventually lost when the cassette I was using failed.

Later we got floppies, a Z80 softcard, 80 column card, language card etc.

I spent many many hours on this machine, coding, playing games, hacking games to give more lives, trying to break copy protected disks, and the like. Remember Zardax? It was an "upcopyable" word processor, apparently quite good by 1983/4 standards. I made the best copy I could, then spent hours trying to figure out why it didn't boot. Never managed to make it work, though...

When the computer store where I worked on Saturdays closed down, I managed to scrounge a ROM card, a complete set of Apple ROMs, and a pukka Apple motherboard (unpopulated). I used the ROM card to crack games, both copy protection and nifty things like getting extra lives and axes in Conan. I still have all my notes, someday I might post it...

I scanned the circuit diagram (54K) that came with one of my floppy controller cards.
