PROJECT: HF-10031
DESCRIPTION: Standard for parallel memory interface (64KB) (1)


Standard Info

This standard was introduced by HF-64107 NVRAM memory module in conjuction with HF-6030 digital system. Male 2x15 goldpin connector (2.54 mm) is installed on memory modules, while female 2x15 goldpin connector (2.54 mm) is installed on digital systems. Space between rows is 15 mm. It is used as external memory for both program or data for various digital systems, especially for 'retro' microprocessors. Program code can be loaded from HF-6030 (inserted directly from keyboard or downloaded from PC) to HF-64107 and plugged into target digital system.
