IBM 5160  -  Significant Differences to the IBM 5150

RAM count-up at power on

At power up, as the conventional memory is tested by the POST, the operator sees an on-screen incrementing memory count.
(On the 5150, the operator sees only an underline character.)

Power supply

Overall wattage approximately doubled  (130W versus the 5150's 63W).

To be noted is that the increase is only for the +5V and +12V output lines; the -5V and -12V lines are unchanged. Click here to see a breakdown.

Floppy drive count

The 5160 expects at least one floppy drive (unlike in the 5150, there is no motherboard switch setting for zero floppy drives).
