- title: 36 MHZ. IN 1982?
|
|
subtitle: ''
|
|
text: The title of this advert was very optimistic. In fact, the 36 Mhz speed is obtained by adding the speed of the 9 x Z80 cards installed into the system. The maximum system speed was in fact 4 Mhz.

After the optimistic 36 Mhz. speed, here is the 64 bits processing power... with 8 bits/Z80 cards. Here also, the 64 bits 'power' is obtained by putting eight 8 bits cards together in the case.\
|
|
Not a very honest way to sell a computer that is no more than a classic S-100 / Z80 based system with some multi-user capabilities.

The BetaSystem was a S-100 BUS based system using a complete computer Z80 card that could handle two time-shared users. Up to nine cards could be installed in the case allowing up to 18 users / video terminals to be connected and used simultaneously.
|
|
|
|
As usual with S-100 based systems, a large range of storage devices could be added to the system: 5.25", 8" or 14" Winchester disk drives from 5 MB to 600 MB, 5.25" or 8" floppies, and tape cartridges up to 100 MB.
|
|
|
|
Mainly based on the UCSD PASCAL operating system, the BetaSystem could also be used with CP/M and TurboDos O.S.
