It was sold in via an 80 Micro ad from Lynn Computer Services and Joe paid me a royalty for each one sold. I ended up writing my first commercial software packages based on that knowledge: a print spooler and a cursor-oriented directory utility that showed you what was on the disk and executed files appropriately based on the extension. I have both of the Soft Sector Marketing published books and I remember swallowing hard buying them (they weren’t cheap if I recall) but the knowledge I gained from looking at that was huge.īoth books disappeared after SSM went out of business in 1983 but I still have my copies after all these years. There were several books that covered the ROMs but only one that I recall for TRSDOS. Not just the assembly but comments, descriptions and callouts covering major functionality.

We’ve seen other heroic retrocomputer recovery efforts before, too, like the work to save the Polish CROOK OS. There are some differences between the scanned source and what Microsoft shipped, which is outlined in the repository. The output was then manually corrected and the source code was complete for both the 32K and 64K mode ROMs. The paper was carefully scanned at the 2022 Dragon Meetup, before passing the resulting images through OCR software. The output of a Motorola assembler was printed back in 1983 at Dragon Data’s R&D facility in Wales, and was recently recovered after being stored in an attic for much of the last four decades. Hilariously, the source code was recovered from 340 pages of fan-fold tractor paper stored in four bundles. This is also known as BASIC-69 or Extended Color Basic.

The repository concerns the Microsoft 16K BASIC Interpreter as built for the Motorola 6809, as used in the Dragon 64 computer. It’s now possible to cross Microsoft BASIC for the Dragon 64 off that list, with the source code now posted for all to enjoy on GitHub.

There are a great many pieces of software of yesteryear that are no longer readily accessible.
