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.
We need more info about this computer ! If you designed, used, or have more info about this system,
