Chapter 2
Joseph A. Weisbecker played a pivotal role in transitioning RCA into the microprocessor era. In 1971, he designed an 8-bit LSI microprocessor referred to as the "FRED microprocessor". Its architecture was outlined in Weisbecker's 1971 RCA technical reports. Between 1971 and 1977 (even before the single-chip implementation of his microprocessor was available), he proposed several low cost, FRED-based computers and game consoles to the RCA management emphasizing the technology's benefits to the computer and consumer electronics industries, education, and electronic entertainment. Some of Weisbecker's designs were subsequently developed into commercial products and successful hobby computers (see Table 1).

The MCM/70's research and development took place mostly in MCM's manufacturing facility
in Kingston. The following three photographs, taken at the Kingston facility, show
the MCM plant, a R&D station (with the rack prototype of the MCM/70
and an MCM/700), and a MCM/700 assembly station. Do you recognize any of the
individuals on these photographs?

In May of 2011, after almost 35 years since leaving MCM, Jose Laraya had an
opportunity to see an MCM/70 computer again at York University.

Photograph 5. Jose Laraya inspects an MCM/70 computer at York University. The
piece of hardware to the right of the MCM/70 was Laraya's first attempt at
building an APL microcomputer based on the Intel 8008 microprocessor.
This prototype used an Intel SIM8-01 development board. (Photograph by Z. Stachniak, May 30, 2011.)

In 1988 Kutt's new company--All Computers Inc.--introduced the ChargeCard,
a little circuit board designed to speed up the operations of personal
computers. The All ChargeCard was awarded PC Magazine's
Annual Award for Technical Excellence in 1988.

Chapter 7
After leaving MCM, Laraya designed a number of computers that were manufactured in Ontario. The Persona desktops were manufactured by a Canadian company Nelma
Electronics Ltd, and became popular microcomputers in Ontario. Another computer,
the Zapstar, was primarily designed for applications in travel industry. The futuristic
lookind computer was unveiled during the 1979 Ontario Travel Industry Conference that
took place on January 19 at the Harbour Castle hotel. The computer featured a "space-age" color display and could be interfaced with 256 other Zapstars.

Chapter 8: Welcome to the computer age!
In the paper A History of APL in the USSR written by Andrei Kondrashev and Oleg Luksha for the ACM
APL Quote Quad (vol. 2, nr. 2 (1991), pp. 8--11), the authors state that the interest in APL in USSR was
triggered by a visit of Pavel Medov, a professor of the University of Toronto to the Computing Center of the Academy of Sciences
of the USSR in late 1974. "In the spring of 1975, professor Medov brought an MCM/70 computer with built-in APL system to the
Computing Center of the USSR Academy of Sciences. The first Soviet APL program was written by Dr. Victor Sokolov that summer. Later
on, another such computer appeared. During the next few years these were the only APL systems available for Soviet users."
(Quote from page 8 of the paper.)
Identifying MCM/70 models
The MCM/70 computers were sold in a range of configuartions identifiable by
a machine's model number on the back plate of the unit. The model number
consists of three digits followed by two optional letters:
- the first digit should always by "7";
- the second digit describes the amount of RAM installed, increments of 2K;
- the third digit denotes the number of tape drives installed in the computer;
- the optional string "EF" at the end of the model number indicates
that the computer is equipped with the extended I/O features.
Known Installations of MCM computers (the MCM/70, /700, /800, /900)
Because the MCM/70 and /700 computers were sold with similar conigurations (models 720, 721, 741, 742, 781, and
782), the list provides no explicit reference
to either MCM/70 or MCM/700 when such an information is missing in source
documents.
