When we combined our highly praised Z7PU board and our System Monitor Board, we
&
detined the standard for the industry; we integrated more power and flexibility in two slots of
our motherboard than most other systems can muster using five or more boards. When we
put this setup into our rugged aluminum case we created the first XITAN system, the alpha 1.
By adding a CRT terminal and or teleprinter you will have a complete Computer system.

By adding a 716 memory module and our PACKAGE A software to the alpha 1 we createda
S second XITAN system, the alpha 2. Thus, a complete and extremely powerful mic ro-computer

Technical Design Labs’s Xitan Alpha range of computers were first released in 1976. Like the Altair 8800, the Xitan Alpha range was based around the S-100but, unlike the Altair 8800 with it’s Intel 8080 CPU, the Alpha range was paired with a Zilog Z80 CPU running at either 2 or 4 Mhz. The Xitan Alpha 1 variant shipped with 2KB of RAM, serial I/O ports, and an audio cassette interface for 769 USD in kit form or 1039 USD assembled and tested. Xitan Alpha 2 adds an additional 16Kb of RAM and a software bundle that included BASIC and an Assembler for 1369 USD in kit form or 1749 USD assembled and tested.
A marketing brochure for both the Xitan Alpha 1 and Alpha 2 can be found at the Internet Archive.
