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.
