The 2nd Computer We had back in the 1980’s at the Autoparts Store had a 10mb HDD that was an 18” Fixed Platter and there were ODD and EVEN Removable Mirroring Platters also 10mb. It required Both Platters to Boot up. It also had 2, 8” Flexible Floppies that were used for Data Backup (also ODD/EVEN) and required 8 to 10 Floppies.
The CPU Cabinet was 7’ tall, 3’ wide and 4’ deep.
The Salesman told Us We could operate 4 Stores with that Machine HA!!!! It would barely run 1 Store with 4 CRT’s, 1 Tractor Feed single color Black ribbon Okidata 8.5” Invoice Printer and 1 Tractor Feed single Black ribbon Wide Paper Report Printer. All Peripherals were run on Serial Cables.
I learned to Type on the Computer Keyboard not on a Typewriter.
Sounds like a CP/M machine, I used one of those as well, still a thrill at the time; also had to use the DisplayWriter (IBM) which used a couple of 8" drives.
ibm?
