Andrew (Australia) Saturday 30th October 2004 Ah, yes, the Microbee C-I-A-B. my dad and his brother Grahame were the founders of what turned into the microbee user's group. good times, says dad. back when most computers had memory measured in kilobytes instead of gigabytes. i still have some older computers my dad owned, like a Toshiba T-1100 Plus...... andrew

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.
