Old computer Part 2

[va7aax]

here is a REALLY cool one.It was called the COSMAC Elf(cosmac was the old name for cmos).It used the 1802, the first CMOS uP.It was featured in a simple project in Popular Electronics.Now, the SUPER cool thing is , you had to toggle-switch in your programming through hexadecimal.!!!!!!!!

It seems like only last week that the 1802 was considered to be on the foreskin of technology!

Sounds easier to program than my FT-1802. Coincidence? :p

It's interesting how the KIM-1 (LINK) (http://oldcomputers.net/kim1.html) computer resembles the ELF. The KIM-1 and ELF share at least a casual relationship in layout and appearance. Perhaps a MOS Technology engineer had built an ELF? Or, since they are both from 1976, it could easily have been the other way around. Perhaps Joseph Weisbacker saw a KIM-1, designed the more simple ELF, and sold the article to Pop Elec. for DIY computer enthusiasts and experimenters.

Remembering these machines, and their contemporaries such as the ALTAIR 8800, SwTPC 6800, IMSAI 8080, Sphere 6800, etc., computing sure has come a long way since the mid-70's. Who recalls paying $200 for a 4kb memory board? How about the god-awful graphic design of the Godbout Electronics ads?
