All, I've decided to sell my Alspa ACI-2, here's the post on the VC Forums with full information: http://www.vcfed.org/forum/showthread.php?70364 Neat little machine, same concept as the Ampro LittleBoard Series 100 (drive box with Z80 SBC) but it uses 8" disks instead of 5.25". The CP/M CBIOS is set up to be able to read/write SSSD IBM 3740 format disks in addition to Alspa's double density format. Thanks, Jonathan
