Electronics kits training kits trainers, Kosmos CP1 computer

As a kid in the 70s, I only had a general Tandy electronics kit. Then soon a Vic-20. Much later I bought a kit from Busch with an LCD display (#2188).
Eds mentioned the great Busch 2090 kit.
-A 4 bit trainer from Germany - Busch Microtronic aka 2090
There’s also now an emulator.
GitHub - lambdamikel/Busch-2090: An Emulator of the Busch 2090 Microtronic Computer System for Arduino Uno and Arduino Mega 2560
I also talked about toy computers and the ITT MP Experimenter.
Another great computer from kit manufacturer Kosmos is the CP1 with membrane keyboard and rare decimal opcodes. There are also several emulators and projects.

There are several (better) photos on the web, but this one showing an open expansion. I also didn’t knew that it can also be combined with robots, cranes and parts for model railways and Fischertechnik.
I found high res brochures on this forum (this one 1983/1984)

Another interesting kit (but not a computer) is this Video kit from Schuco/Philips with small oscilloscope. I have never seen that before. Maybe it can be used/reused for making a computer (or game).

Some more here
Another video kit for use at a TV is Philips EE3023. At least someone can make a video game with it (probably Pong). More details also there.

Also of interest the Philips MasterLab MC 6400

Another, 2006 Kosmos kit (incl Windows tools) I never heard of before is this one
Best site with illustrated part lists and manual is this one, this subpage for the 2nd video kit. On the left are links to all kits, though difficult to identify the manufacturers there

I can only speak for Germany, what about experiences/kits in other countries?
I always considered buying a CP1, but there are enough emulators. And the most interesting part (of most kits) is the manual.


Excellent finds! I did have a Philips electronics kit - fibreboard, springs, and a scant handful of transistors each mounted on a little square carrier - just as mentioned in the EE 3023 page. But mine was limited - I think it included a ferrite rod and an AM radio receiver was possible. The instruction book was excellent, as I recall, and I bootstrapped some basic understanding of electronics from it.


Replying to this rather old thread - but I just made a rather extensive series of YouTube videos featuring some (mostly early 1980s W German) educational systems, including the

  • Kosmos CP1
  • Busch Microtronic
  • Philips Masterlab
  • Science Fair Microcomputer Trainer from 1976

This playlist includes system demonstrations, performance evaluations, and hands-on programming videos:


For example, here I measure the performance of the MasterLab 8070 SC/MP III machine, and it turns out that it is executing 147,050 instructions per second (yes, 147 thousand!) - this makes the machine 1290 times faster than the Busch Microtronic, and about 79 times faster than the Kosmos CP1.


The Schuco/Philips kit is an interesting one.

I wonder about the “ZDF” (a German public broadcasting channel) on the screen: may this have been related to an educational TV program, or is it just a demonstration of TV capabilities?

I don’t think about an educational program on ZDF.
Almost all educational programs were on the local channels 3 (WDR, BR etc) due to different German state’s school politics.
Probably just to show that it can receive broadcasts.

In the meantime, I was asked to provide a little demo / tutorial on how to use the cassette interface of the Philips MasterLab MC 6400. Here you go:
