My first job after graduating from Maryland in 1984 - writing 6502 assembly for a voice/data switch and feature phones for GTE's OMNI series. Yes, the Leventhal book was all there was back then (it still sits on my shelf). I was working with some incredibly talented hardware and software developers, and the learning experience working with assembly and hardware was unmatched.
Later moving on to the Motorola 68000 series chips which were great, but just not as fun as working with the 6502. The 6502 was so simple and well designed, writing in assembly was actually productive.

To this day, the best job I've ever had.
