The Alspa ACI-2 is an integrated CP/M system. The chassis houses one 8” full height floppy drive (the ACI-1) or two half-height drives (making it an ACI-2).

While the machine at first appears to be an external drive box, there’s a single-board Z80 computer mounted below the disk drive(s) that provides for a full, integrated CP/M system.

The ACI-2 single-board computer includes a 4 MHz Z80, 64K of dynamic RAM, boot ROM, a double density floppy controller, three 8251A serial ports, and options for a parallel port, battery-backed RTC, and Corvus hard disk interface.
