This is a modern implementation of the 8088 minimum mode SBC based on the one from Walter Fuller as used in his book "Build Your Own Computer".
The orignal design as built in the book appears to have been done on a breadboard, so I took the basic design and implemented it (partially) in an ECB (100mm x 160mm) format to take advantage (ultimately) of various peripherals available in the Retrobrew Computer board series.
As currently drawn, my reimplementation makes the following changes:
-
Adds three 73LS373 drivers for the address bus in the event I want to expose those to the ECB connector (which right now is only for power).
-
Removed the ADC0808 analog-to-digital converter.
-
Used only one 82C55 I/O chip.
-
Removed the RS-232 level shifters in favor of a header for a USB dongle.
-
Added jumpers for the EPROM to allow for a flash-equivalent chip.
As of now, this design is untested but I don't see why it wouldn't work.
