ZX-86/05A

The ZX-86/05A is ideally suited for ROM-intensive control and I/O applications. It is designed to work in both a stand-alone or multi-master system.

Custom I/O and special functions can be configured with the addition of up to three additional SBX modules. An additional serial port can be obtained by using the Z8OB S10/0(MK3884) serial I/O chip. 

Eight memory sockets provide 512KB EPROM. Optionally, these sockets can support four SRAM (up to 32K each) and four EPROM devices.

This is the only 86/05A board which provides three SBX connectors, dual USART's and 512KB of EPROM.
