river Forums Junkie Location: Land of Oz Registered: June 2004	My really old computer Tue, 05 April 2005 12:06 Hi, I've just had a blinder and exceeded my own expectations in building a circa-1976 computer. This baby is running at a whopping 2.048Mhz and has 8K EPROM and 4K of RAM, a comms port and 3 parallel ports (8 bits each). The CPU is an old National Semiconductor SC/MP processor, that is so crude and weak that it's almost fun trying to get it do anything useful. Anyway, I've just finished completing the hardware build and it's currently running a comms test. Now the fun part begins 'cos I've got to develop a monitor/debug for it. However, that will have to wait 'cos some dudes on another forum want me to finish off my 6502 system first. I think I'm better at doing maths in binary/hex/octal than decimal! I love this old shit. seeyuzz river [Report message to a moderator]
