OK I'm back to old habits -- having re-discovered old habits weren't completely stupid.

Leor Zolman's BDS C compiler it is. It's got a lot of language cheats and shortcomings, but it's all scaled appropriately for small machines.

It's binary output is HALF the size of Aztec C's, which is fairly compliant (to a very old standard). I need code, not compliance.

WordStar has many shortcomings, I could not remember how minimal it is, but it is rock solid and that matters.

I'd like to find a copy of PMATE for CP/M (plenty around for DOS)

Leor seems like a great guy.

CP/M-86 for Newbies is a starter kit for CP/M-86 with everything ready to unpack and run. It bundles the PCe PC emulator (Windows only), preconfigured PCe environments for running different CP/M-86 versions including Concurrent CP/M-86 and Concurrent DOS, and other software such as the Pirx Commander file manager.

Wow, I didn't realise that LibreOffice turns 40 this year with it's latest release.

It started out as closed source Star Writer for CP/M in 1985 with DOS 3.2support in 1986.

Then became Star Office in 1994 for Windows 3.1

It became open source as Open office in 2001 and the LibreOffice fork in 2010.

👆 So, concerning that "CP/M subsystem" I posted about on April's fool day.

It's not a native Lisp component of Medley Interlisp from back in the day but a modern CP/M emulator written in C, see the link. It runs in a Linux shell on the host system accessed from Medley's own VT100 terminal emulator "Chat", which is what you see in the screenshots.

CPMImage is a GUI front-end for cpmtools, the popular suite of tools for accessing CP/M file systems.

It's similar to WinImage but, unlike WinImage which is Windows only, CPMImage runs also on Linux. The tool is in an early stage of development and is actually cross-platform as it's written in Python with Tkinter.

This article is a great biography of Adam Osborne and a history of his endeavours in the computer business.

A couple of parts are of particular interest to me. One is about the software shipped with the Osborne One and the state of software bundling at the time. The other part is the aftermath of the demise of Osborne Computers, which I knew little about.

I didn't realize it at the time but the release of the DEC Rainbow 100 was a big deal back then.

This post explains why and sheds some light on this little known PC, such as the seemingly reasonable design decisions and the market forces that doomed the machine.

The Silicon Underground · DEC Rainbow 100The DEC Rainbow 100 from 1982 was an early challenger to the IBM PC. In this blog post, I explore why it failed in spite of being better.

This 1982 interview with Gary Kildall is interesting because it focuses on CP/M-86 which is little known.

It made me notice a difference with MS-DOS I hadn't thought of before. Like Unix and unlike MS-DOS, CP/M-86 shipped with a complete software development environment with tools such as an assembler, which might have contributed to the higher price.

does anyone here know of any CP/M text editors that play nicely with 40x24 terminals? so far the only editor ive found that (mostly) works is the Turbo Pascal editor, which is not ideal. of course, the standard ED works, but i'd rather not use that unless i absolutely have to. #cpm #cpmz80 #tms9918a #rc2014

Mklbr is a Linux and Windows tool for creating .LBR file archives.

It's the only such tool I found for Linux whereas .LBR unarchivers are more common. Mklbr is very valuable for transferring bundles of files to the homebrew computers running CP/M many retrocomputing enthusiasts use, such as my Z80-MBC2 or the RC2014.
