The Computer-In-A-Book (CIAB) was released just after the Microbee 64. This strange machine was composed of one main unit and at least two 'books'.

The computer was actually not in a book, but in the main unit, a Microbee 64. The first book held the user manual in a ring binder, the second book (Vol. 1) held a - new at the time - 3.5" floppy-disk drive and a power supply unit which supplied the main unit and the drive. This unit could also supply a second slave disk-book (Vol. 2).

The designer's idea was to offer a low-cost and expandable CP/M machine. Up to 4 disk-books could be connected in chain. Even though the idea was original, the day-to-day use of these light units wasn't very convenient. The bad idea was to mount them in a bookcase, between other books, causing PSU to overheat and system failure.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
