Description

CAUTION! UNTESTED – WORK IN PROGRESS – UNDER CONSTRUCTION

Retro Brew ECB BUS to 8 Bit ISA CARD adapter

I plan to solder a 62 pin ISA BUS connector to the top of the card
and use a right-angle C96 for the ECB BUS connector.

This will allow the adapter to plug into the ECB Backplane.

I want to have a box full of ISA cards and would like to try using them with my ECB systems.

I already have a working ECB to RC-2014 adapter
