Adding Magnetic Bubble Memory to a vintage computer, an iPDS-100 Personal Development System

In this video, I take an iPDS-100 vintage computer circa 1982 and add Magnetic Bubble Memory to it. The iPDS-100 was manufactured in the early 1980s by Intel and was sold as a personal development system, featuring EPROM programming and emulation capabilities for 8051 and 8085 CPUs. This particular iPDS-100 has two 8085 CPUs in it, allowing you to run two programs concurrently on a split screen. This allowed you to not just program EPROMs and emulate processors, but also to run a variety of software such as editors, assemblers, compilers, etc. It ran an operating system called ISIS-II, and it also ran CP/M. My iPDS did not include the necessary iPDS-120 "multimodule adapter" necessary to plug the iSBX-251 Bubble Memory modules into it. So I built my own! It was a little difficult getting the dimensions exactly right, but I pulled it off and was able to install the replacement adapter and get my iPDS to use bubble memory and to boot from it. I also show how to blank check, program, and verify a 2532 EPROM. For more vintage computer projects, see https://www.smbaker.com/
