Olivetti M4-6X / BA2054

RH-PHJW

This 1994 Olivetti M4-6X/BA2054 motherboard is interesting.There is no power connector, RTC battery or ISA slot. It has a soldered-on 486 SX 25 with 4 MiB RAM, Cirrus Logic VGA and a peculiar 34-pin CD-ROM interface. Several documented BIOS revisions. Neat. Very Olivetti!
