The Olivetti PC 1 was designed to be a family computer and Olivetti’s answer to the [Amstrad PC 1512](/museum/amstrad-pc-1512/).
|
||
|
||
It uses the TV screen instead of a special monitor, but one could be used if you wanted to use one. It was sold with a mouse.\
|
||
No internal slot : to use ISA cards, an expansion box had to be connected onto the expansion connector. This device supplied two 8-bit ISA slots, hard disk connector (for a 20 mb hard disk, 85 ms) and 128 KB ram. It runs under MS DOS 3.2.
|
||
|
||
The most particular feature is the disk-drives mounted above the keyboard. The computer was sold with 1 or 2 of them.
