I have a working M18P modified by adding a 20K hard drive and replaced one 5 floppy drive with a 3 1/2 720K drive. Anyone interested?

I own an example of this computer. Mine is a very early machine, the serial is very low and it was made just after they announced it in December of '83. Keytronic made the keyboards, a capacitive unit like that of the Compaq. Shugart supplied many of the drives. These Olivetti rebrands, like the Underwoods and Philips machines, are identical with exception to the badge on the front. Docutel/Olivetti announced their partnership with Corona in January of '84. Corona would ship 5000 units in those two months. 512K is the maximum amount of RAM applicable without an expansion card, so there is no factory provision for 640K. Not a lot of information is out there on these without a intensive search.

This machine was a private label of a similar Corona Data Systems Portable machine. In fact the mother board in my own personal machine has a silk badge of Corona Data Systems.

I have an identical machine and have an external 10gig hard drive as well. Does anyone have any interest in this antique unit??

this machine looks exactly like a Corona Portable Computer - seems to be a clone.
