My first computer was based on an Intel SBC 80/30 running an 8085 at 6.144mHz with 4k rom and 16k ram on board. It had an additional 32k of RAM on an option board along with a ROM based editor/assembler. The console was a Teletype ASR 33 with a paper tape reader/punch. It was fun. Come home for lunch and turn on the system. Start a paper tape load, eat lunch (15 mins), edit program, start paper tape punch to save work, wait 15 mins, turn off machine and go back to work. And you guys thought cassettes were slow.
