I put mine together over a couple nights, having not picked up a soldering
iron since summer camp in the early '70s (assembling radio shack kits on red
plastic boards).

I had *no* errors with the kit, it worked perfectly after assembly.

I'm considering his newest project, an Ohio Scientific SuperBoard - it has an
on-board keyboard and will be about $230.


That was my second computer, my first was a SYM-1...
