Description

RetroBrew SBC-188 version 3.2 (80C188 single board computer)

Reference Shared Project "RetroBrew SBC-188v3.1" for detailed information. This revision is the exact same circuit as the 3.1 revision, but with 3 jumpers added in the yellow rectangle to allow easy connect / disconnect of interrupt sources. On the 3.1 board, disconnecting an interrupt involved bending pins upward on the 74LS05.
