Recently, we acquired some teletypes for the collection, one of them is the RFT F2000. The F2000 features microprocessor control, not like the earlier models which rely on motor driven mechanisms for the encoding and decoding of the signals. Here are some photos of the restoration process. Another interesting thing is that the F2000 features in a mostly toolless design.

Recently we found another Pravetz 8D on auction for a good price and in good condition. No matter that we have a few units in our collection, we decided to save this one as well. You can never have too many Pravetz computers. 🙂 On first sight the unit was in mint condition, even the…
Most of the so-called “Home computers” we have in our collection were meant to be used with the old bulky CRT television sets. Back in the day you would use a coax cable to connect your computer to the TV via the RF input. Some models like the Commodore 64 have a dedicated RGB video output and you would solve the problem…
The final part of the restoration is to clean up the monitor and test everything. Removing the top case reveals the chassis type monitor. The next step for the future is to create a Wi-Fi modem with an ESP8266 microcontroler for the terminal. This will give us the ability to connect it to the internet…
