![]() ![]() Ampro had taken advantage of the latest in semiconductor developements, incorporating all the essential elements of a CP/M computer on one tiny board - CPU, 64K RAM, boot EPROM, battery-backed clock, terminal port, modem port, printer port, and floppy disk controller. CP/M was the most popular computer operating system in the late 1970's and early 1980's, before Microsoft MS-DOS took-over, following the release of the IBM PC in late 1981. The Ampro Little Board can be be mounted directly on the bottom of most mini-floppy disk drives, using the four standard threaded holes, with support for 1 to 4 single or double density 5 1/4-inch mini drives. While the $349 Little Board is a capable single board computer, the owner still has to supply their own power supply and floppy drives. A few months later, in September 1984, Ampro released their own complete computer system, the Ampro Bookshelf Series 100, featuring the Little Board, a built-in power supply, and 1 or 2 built-in floppy disk drives. Althought the Book shelf computer was a kit that the purchaser had to put together, it was mostly assembly with no soldering required. The Bookshelf comes with an enhanced version of CP/M 2.2, called "Friendly", which allows the user to access any program just by pointing to a menu entry on the screen. The screen displays the disk drive directory alphabetically, and you select what program to run by moving a cursor. ![]() Since CP/M was nearing obsolescence, 1984 was very late in the game to be releasing a CP/M computer of any kind. Within a year, Ampro released additional Little Board single board computers, but these later systems were MS-DOS and PC compatible.
