Raspberry Pi Helps TRS-80 Model 102 Deploy Kubernetes
It is nicely documented that the Raspberry Pi has helped many older computer systems do greater than they had been designed to, and that is Project from Darko Mesaros It allows the 37-year-old TRS-80 Mannequin 102 transportable laptop to deploy Kubernetes.
Let’s be clear, the TRS-80 Mannequin 102 (also referred to as Tandy 102) lacks the horsepower wanted to deploy and run Kubernetes. However what it may possibly do is change into a terminal over a distant connection. To do that, Mesaros wanted some assist getting on-line and used a WiModem32 related to the TRS-80’s RS232 serial port. This serial Wi-Fi modem is actually an ESP32 that makes use of old-style modem instructions to connect with immediately’s Wi-Fi units. Mesaros was capable of set the baud fee to 300 utilizing the TRS-80’s built-in terminal software (TELCO) after which difficulty an AT command to attach the system to their WI-FI APs.

That is the place the Raspberry Pi enters the story. Raspberry Pi is used as Telnet server. Mesaros configures the TRS-80 to connect with the Telnet server and from there they’ve entry to a full Linux working system that’s greater than able to deploying Kubernetes.
The TRS-80 Mannequin 102 is known for its type issue and keyboard. Journalists of the interval would write copies and ship them to the newsroom utilizing a built-in modem and acoustic combiner (identical to within the film Wargames). At the moment, 32 KB of RAM and Intel 80C85 The CPU was sufficient for journalists within the area. Add to that 20 hours of runtime on 4 AA batteries and you may perceive why the Tandy 102 is the go-to transportable of its time.
The undertaking is extra for leisure than sensible, but it surely exhibits how the retro neighborhood is embracing fashionable applied sciences (Raspberry Pi and ESP32) to boost retro applied sciences and convey new options.
