The Kenbak-1 was given the distinction of being the worlds first commercially
available personal computer by a panel of experts
put forward by the Boston Computer Museum
( now the Computer History Museum) back in 1987.
Front panel design
Designed, Built and Marketed by John V Blankenbaker back in
1970-73, it epitomises true vision and set a new standard of thinking.
It is a single board computer with no single processor chip, the
processor is constructed by TTL logic gates, it has a programmable memory
of 256 bytes and an instruction clock speed of about 1MHz.
The Kenbak-1 uses binary/octal machine code (great fun) this is
a link to very good emulator.
Single PCB or Mother board
It only had a very short production run of about 40 units.
In 1973 the Kenbak Corporation sold the rights for the Kenbak-1 to
CTI Educational Products Inc.
It is believed that very few Kenbak-1's were produced by CTI.
The Museum's Kenbak-1 has the CTI logo.
Its Blue case was also produced by CTI, Mr Blankenbaker informed us
that he used cases manufactured by Bud Industries which had a slightly different layout.
He also said the front control panel had a horizontal slot cut in it to potentiality fit a
card reader in the future, this unit does not have this feature.
Very interesting description of the
