In 1972 the CL 1600 series consisted only of the basic kit CL 1601, while the expansions CL 1602 and CL 1603 were planned. The following year not only these two, but also a third expansion appeared: CL 1604, and a fourth was planned: CL 1605. This was released the next year, but only after a smaller basic kit, CL 1650. This year the unrelated CL 1640 kit also appeared. It is uncertain how long it stayed in production; in any case it is so rare that I have never seen any reference to it outside the 1974 catalog. It was gone in 1976, while the rest of the series survived unchanged until 1980, and was discontinued in 1981.
These kits does not contain anything remotely like a complete computer,
but just show the basic use of digital logic circuits. Constructions are
made by wiring together a power supply containing 6 on/off input switches
with a number of logic units
. Each of these units has three inputs
and one output (whose state is indicated by a lamp), and can be
programmed
to act as various gates and flip-flops through simple
internal wiring.
According to the description, CL 1640 was an entirely different kind of
kit than the other ones, aimed at teaching basic set theory using
pre-programmed punch cards on an electronic control panel
. I have
no idea how this looked, as unlike the other kits I have never seen
pictures of its interior, and the box lid use the picture from
CL 1650.
The later 6400 or ABC
series consisted only of 6400:
Microcomputer Master Lab, appearing in 1983 and staying in the catalog
until 1986. In a supplement to that year's catalog, the number series was
taken over by 6401 Töpferei (Pottery) and 6402 Holzgraveur (wood
engraving). The kit probably never sold very well, as I have never seen a
version bearing the Schuco logo.
Unlike the CL 1600 series, 6400 contained a complete computer with CPU, 4 kB EPROM, 1 kB RAM and an 8 digit display.
I have never seen any Quelle versions of any of these kits.

As the series grew, the CL 1601 manual was gradually extended to cover all kits, except the unrelated CL 1640 kit, for which I have never seen a manual.

Early versions of the add-on kits included the necessary new material for use with an older main manual.
