The Busch 2090 learning computer of 1981 may be a niche thing in a niche thing but over the years it every now and then sparks the interest afresh in some of those who wanted to have or actually owned this 4-bit computer back then as a teenager. 12 years ago must have been such … Continue reading Reviving a Busch 2090 Emulator
Today another post in my popular series on historical computing. When the Busch 2090 microcomputer learning kit came out in 1981 it required the user to write programs on paper, translate the instructions to machine code and to calculate memory addresses and branch destinations himself. In an iterative development process this is more than just … Continue reading An Assembler for the Busch 2090
After having found out how I can make my vintage 1981 Busch 2090 microcomputer board output a program from memory to the 2095 cassette interface board I was hoping that the knowledge I had gained during the process would help me to reach my ultimate project goal which was to send a 2090 program from … Continue reading Emulating a Busch 2090 Tape Interface – Part 2
Back in 2013 I finally managed to get hold of a Busch 2090, a historical microcomputer learning kit I always wanted as a teenager but couldn’t afford. Apart from its historical value to me it is still a great tool to learn and better understand how computers work. At the time, Busch also sold a … Continue reading Emulating a Busch 2090 Tape Interface – Part 1
Over the past years I’ve explored many ways how to combine my memories of computing of the 1980’s with my quest to better understand how a CPU works and using contemporary technology for the purpose. Here’s another cool approach to do this by emulating a Busch 2090 4-bit computer on an Arudino.
It took a while to get hold of one but I finally managed to get a 1980’s Busch 2090 microcomputer I mused about in this and other previous blog posts. What I could only read about in the manual before I could now finally try out myself on this 30 year old machine and true … Continue reading Historical Computing And The Busch 2090 – Simulating A Newer CPU Architecture On An Old Processor
We are quite a bit into January 2018 already and I still haven’t come around to reflect which things from back in 2017 ‘moved’ me. But finally here we go this is my 2017 round up from cellular to history.
An event I’ve been looking forward to for a long time is this year’s Vintage Computing Festival Berlin (VCFB) which takes place in about one and a half weeks from now, Saturday and Sunday on the 7th and 8th October 2017 in the German Museum of Technology in Berlin. If you are even only remotely … Continue reading The VCFB Vintage Computing Festival Berlin – 7.-8. October 2017
The year is drawing to a close and I had some time over Christmas to reflect what has been going on this year and I found quite a number of defining moments on the technology front. Here's my personal top 10 list of things that mattered to me personally in technology in 2013 1. LTE … Continue reading My Personal Technology Highlights in 2013
There's one thing I have been wondering about while enjoying my recent trips back in time to the 1980's and computer learning kits: Were there similar kits in other countries around the globe tailored for teaching teenagers how computers work (vs. how to work with computers)? In German speaking countries there were three different kits … Continue reading Were There Computer Learning Kits for Teenagers In Your Country?
