I found IMSAI 8K Floating-point BASIC … and it works on the Alpha!

In a prior post, I wrote about the effort to modify Palo Alto TinyBASIC to run on the OMEN Alpha. In this post, I'm going to write about the IMSAI 8K Floating-point BASIC that was written for the IMSAI 8080 microcomputer. In my search for various "vintage" software for the 8080/8085, I ran across across … Continue reading I found IMSAI 8K Floating-point BASIC … and it works on the Alpha!

How to use the OMEN Alpha and MON85 to test and debug programs

In the prior post, I showed the method used to modify and debug new features added to TinyBASIC using the OMEN Alpha 8085SBC and MON85. In this post, I'll expand on that method and illustrate how to test and debug interrupt-driven code. In this example, a program that uses the RST7.5 hardware interrupt will be assembled … Continue reading How to use the OMEN Alpha and MON85 to test and debug programs
