OK - I am getting better at making CP/M disks, so I hope to get my better camera setup this weekend, and post a nice tutorial.

For now, we'll go WAY back in time to 1978. Here are some screenshots of MicroPro's WordMaster 1.07a.

Here's a DIR of the WordMaster disk. The "PIP PRN:=*.ASM" commands copy files to the printer (a Panasonic KX-P2134 24-pin dot matrix, hooked up via an MPP 64kB print buffer / Parallel to SIO interface). CP/M has the convention of Destination, Source (not the now familiar Source, Destination). It is rather confusing.

Here is the much more advanced WordStar 3.0 from 1981. In this video, I first use the Indus GT's CP/M specific program ICDS.COM. It allows copying between two drives, and is compatible with the ATARI DOS double-density (180K) disks. I am copying an assembly language file over to the Indus, because the native drive is much faster than the Atari drive running through the SIO port. Once the file is copied, I launch WordStar, open the file, and scroll through it.

The terminal is quite slow. This 80 column version uses an Antic F screen (BASIC graphics mode 8 ). This means it is in bitmap mode. I am in the process of disassembling the file, but it will take me quite some time as it's my first, and there seems to be several sections of data inline with the code.
