I had the first "personal computer" in the dorm. Before the word "PC" befre "windows", before "MS DOS".
I had a 2mhz 8080 with 16k of memory and tape backup. I think it had about 0.3mips. I updated to a 4mhz z80 board and added memory boards to get 48k of memory. I had two 8 inch floppy drives. Wrote the interface to get the floppys working. My first hard drive was 5Mega. It held the operating system, word processor, spell checker, spreadsheet and all my files. There was mega(s) bytes left free. I could not think of how I could fill that hard drive. $500.00
Key words: S100 bus, 8088, CPM 1.4, It had rows of switches on the front panel. I have worked on older computers but that is my oldest one.
Now I have a dual core 700mhz computer in my shirt pocket.
