Great New Find: Olivetti L1 Computer

I think that perhaps you have an M20, which is in the L1 series. Have a look at this page: http://www.rgmconsultants.it/tix/lista/dati/m20.htm and see if that doesn't look something like your unit. There's some specs for the M20 at: http://home.debitel.net/user/groener1/comp_029.htm#M20 I just picked up an Olivetti L1 Computer at Goodwill. The CPU, keyboard, and disk drives are in one unit, kind of like an Apple III. The monitor is seperate, and gets its power from the main unit. All the main keys have BASIC statement on them (PRINT, OPEN, INPUT, etc...). When it boots up, it says: Bootstrap Loader Version 1.0 Insert Disk And Press Enter. Does anyone know anything about it? I couldn't find any information on the internet. Does it have BASIC in ROM? If so, how do I get to it? If anyone has any disks or manuals, that would be great! Thanks, Owen
