ok. so i got to thinking about this since i finally built a new one for myself. at first i thought it was the 286 with a 10 meg mfm hard drive. then i realized this:
in college(1983) i had a challenging class "microprocessors". built and designed a wire wrapped comp that consisted of about 30 ic's.
sys spec:
1k memory(2 chips)
keyboard: 16 momentary buttons wired in a matrix fed to encoder chip + debounce circuit, toggle switch to route keypad entries for data and address
input display: 4 7-segment led's (assembler)
output display: 8 led's for data 16 for address (reads binary)
power supply: stepdown transformer with bridge rectifier (+5v only)
cpu: intel 8088 (2 8085's in parallel)
runs on assembler code
all this stuffed into a briefcase. lol...a dual core laptop.
