  3. A few years earlier (1974) I was watching our USAF base level computer upgraded from 128K to 512K of core memory. I was told the cost was around $250k to do this.

    These type of disk drives were pretty fast because they had one R/W head per disk track. Disk head crashes, relatively unknown now, were a distinct possibility. You never forget the first one you hear!

  4. That's the Willy Wonka screening room when they shrank Mike TV.

  6. I used to own several floor standing disk drives for several old HP 3000 mini- computer I used to own. Stood nearly waist high, about 2’ wide by 3’ deep. Capacity was 50 Mb for one HP 7920), and 120 Mb (HP 7925). I later upgraded to 404 Mb drives (HP 7933/7835) - same physical size. And boy did they suck diown electricity and put out heat - especially when they were being heavily accessed.

    Yeah - things have changed a bit...
