    text: Instead of selling the original Sharp FDD unit, the Sharp French subsidiary (Sharp Burotype Machines) preferred to made their own unit. The case could hold up to 4 drives. The drives were Canon models.

Successor and enhanced version of the [MZ 2500](/museum/sharp-mz-2500/). It is based on 80286 CPU but is also equiped with a Z80B to keep comptability with the MZ 2500.

It has almost the same characteristics but has a HDD port and MIDI input/output ports. The ROM is big: 64 KB for IPL, 256 KB full of 2965 JIS 1st level chinese characters + 3388 JIS 2nd level chinese characters + 535 non chinese characters, and even a 256 KB dictionary!

The specifications listed below are those of the MZ-2861, it may differ from the original 2800...

More info needed!
