I still have one of these, it has not the DD floppy drives$ it has two 1.44MB DSHD drives. Oh, and just giving it a power on test before deciding what to do with it, you have the option on boot, during POST, as to whether or not to use Turbo Mode.
Now I know it works, I think I''ll blow the dust off a couple shrinkwrapped disks and load the thing up with DOS EDIT. After all, you don''t need four cores and 8GB of RAM just to type a document, right? For that matter I could go completely retro and do my HTML coding on the thing as well!

text: I think this model was later equipped with a 20 MB HDD, taking over one of the FDD bays. I bought the double FDD version and was annoyed to find the HDD variant in store at a similar price a few weeks later! Although there was a wedge-shaped proprietary mouse, it was not supplied as standard in the UK, but cost about £30 extra. (Of course, you could use a serial mouse so long as you put the driver on your boot diskettes and amended autoexec.bat.) When I bought one in late 1988, it was bundled with the First Choice integrated software suite, which was excellent in its day, turning the machine into a versatile home office system.

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.
