Vince: Very true! I believe this model 2 is still available from 'Ticonderoga Computing' and has been licensed to other distribution companies such as Staples, Office Depot and the like. I understand that other models are now available as HB, 2.5, 3 and 4. They still seem to still work ok with no need for a UPS in line with it incase of power failures! When I was a youngster (much younger in fact!) I built from Quest Electronics the Cosmac Elf kit based on the RCA 1802 processor. Could this be the machine you started to build Allen? Anyway, Popular Electronics ran a series of articles on building this box with 256 bytes of RAM that you toggled in a program with switches in binary. There were 4 LED displays. 2 for the address and 2 for the byte. The Quest version had a hex keypad to simplify the programming. I wrote a program to send my ham radio callsign in Morse every time I hit the run switch. There was a discrete LED that could be programmed to blink so I modified the board to trip a relay to key the transmitter. That started the microcomputer craze for me. Jack

My understanding is that the problem with them was they had a limited number of writes/rewrites. --- _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://mail.leafe.com/mailman/listinfo/profox OT-free version of this list: http://mail.leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/7d9e7f72b813014c8fd022cf04f820edf36eb...@ex08.drdad.thenewarkarena.com ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
