Yeah, when I saw it, I was floored. I used to have a stack of Transactors
that the school library gave me, because no one was interested in them.
Read every paragraph, sentence and word of them. Problem was, I never
really understood the nitty gritty, mainly because I had an Apple II.

I miss the days people would glue stuff to your PC for fun. I remember
reading a book called...Osborne Book of Computer Stuff (okay, I made that
up) but it was a British book about computers. One of the later pages
described building a robot by using relays, but it didn't give any specifics
like what pins to use on the expansion card or how to poke those interfaces,
because it was a general book that covered Spectrums, Commodores, BBC Micros
etc.
Nowadays there's a lot fewer homebrew projects (the computer market and
users have matured) out there. Maybe that's why people are into Mindstorms.
Or Linux. (gasp)

I really wished I had done something like that-I got in a lot later with the
MIT Miniboard.
I remember reading a Compute! (now that's a blast from the past) article
about Lego releasing a product called Lego TC Logo for the Apple II. Boy
did I want to get one of those. I guess we didn't have the Internet so I
couldn't really

I know...I miss those machines from a nostalgia standpoint. I had a
PET2001-32N (proper keyboard) and an Apple II Plus clone. God knows how
long I used them until one day I made a the harsh discovery that you
couldn't hot swap expansion cards (I think it was the 16K expansion or the
DiskII controller). I guess I was ahead of my time. :)
