Another one for the collection. The Psion Series 3 personal digital assistant. This little device containes all the basic functionality you would expect from a PDA of that era. It also had it’s own built in programming language. I have got a serial cable on it’s way for this so will try and get it online when that turns up, because why not? 🙂
I have seen a few YouTube videos about this little device. It is an adapter board that plugs into the original Denise chip socket on the Amiga 500 and then has a raspberry pi zero connected into it. This then allows the Digital RGB signal directly from the Amiga to be output via the HDMI of the pi giving a pixel perfect digital output.
The actual RGBtoHDMI project was originally designed for the BBC Micro but has since been adapted to work with many other retro systems. The Amiga version requires an adapter board designed by C0pperdragon and can be found here.
The adapter boards are available for purchase but the waiting list is apparently quite long so I decided to get the bare PCBs ordered from JLPCB and ordered the components from various places and then built my own over the weekend. Suprisingly it worked first time!
The only issue with using it on an Amiga is that it doesn’t output the audio, so you either need to connect the audio up to an amp via phono cables or get a device to inject the phono audio into the HDMI signal. I have ordered one of these from China so will test it when it gets here to see how well that works.
I am of the age that at school we had these beauties in our classrooms. I remember designing many circuit boards on one of these in our Design and Technology classes. Well finally I now have on in my collection.
I have already replaced the power supply capacitors which were ready to explode (This is common on all BBC Micros).
Another mod I have also done is fitted the user port with an MMC interface which allows me to load BBC software direct from an SD Card.
Still plenty of more mods to come. Next will be the raspberry pi co-processor upgrade.
First things first. I’m off to play Elite, happy flying commanders o7
After many months of waiting and monitoring eBay. I finally managed to acquire a serial interface for my Atari Portfolio 🙂
So now along with plugging it into cash machines to take out as much money as I want, and breaking into the secure areas of Cyberdyne Systems, I can also connect up to my WiFi network and browse the BBS’s
Incidently my WiFi network is named “SKYNET” so it’s pretty cool when I connect the Portfolio up to the ESP 8266 based MoDem to see the phrase “Connected to SKYNET” showing on the screen. It’s the simple things that make me smile.
Been messing around with the MSX recently so thought it was a good time to do a small write up.
