This is a TEC-1G Z80 Single board computer bare PCB Board V1.11. Shipped from Florida, USA.
For those people looking in the USA for the PCB board and can source the parts themselves, the BOM is here: else you need is located on GITHUB at https://github.com/MarkJelic/TEC-1G
The TEC-1G is a direct descendant of the Talking Electronics Computer, known as the TEC-1, which was first published by the Australian electronics hobbyist magazine "Talking Electronics", between 1981 and 1991.
The TEC-1 was developed as a learning computer, designed to teach the basics of how a microprocessor works at the fundamental hardware and software level, and offered the ability to create and run simple programs in Z80 machine code. TE magazine covered the TEC-1 in six installments, known as "Issue 10" to "Issue 15". These magazines can be downloaded freely from the TEC-1 GitHub, located at[link removed by ]
The TEC-1 was revived around 2018 with a release of a reproduction PCB and related peripherals on the Internet. Retro computing has become quite popular of late, and so an active TEC community has (re)formed through Facebook ([link removed by ]) with new hardware designs, enhanced versions and various expansion options being offered by various contributors within the community.
The 1G builds on both the TEC-1's base and recent history to modernize the overall design, address various design limitations and integrate many of the excellent add-ons into to a single PCB for the first time.
The TEC-1G remains true to the original TE design goals: it is is built using only simple through-hole TTL logic chips so it is easily built and understood by the hobbyist. For the first time, the TEC-1G will also be fully free and open source, in both its hardware and software. The TEC-1G is the ultimate TEC-1!
The 1G has been developed by Mark Jelic with the input of the original designers, John Hardy and Ken Stone, ex-TE staff member Craig Hart, along with contributions from community members Brian Chiha and Ian McLean. Finally, the 1G has also been produced with the blessing of Colin Mitchell, the owner of Talking Electronics.
