I have an Intel iSBC 80/20-4 SBC. With this, I would be able to build a System 80/20 with the iSBC 064 and iSBC 208. I have no documentation on this system other than the SBC Hardware Reference Manual. I have the Monitor listing for the System 80/10 and the monitor listing for the System 80/30. Since the iSBC 80/20-4 contains an 8080 processor vice an 8085, and has one 8259, I should be able to modify the iSBC 930 listing to support an 8080 instead of the 8085 and have a very close copy of the original monitor. The two monitor listings I have are nearly identical except for processor and 8259 support.
