Paolo Amoroso<p>👆 So, concerning that "CP/M subsystem" I posted about on April's fool day.</p><p>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.</p><p><a href="https://github.com/jhallen/cpm" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="">github.com/jhallen/cpm</span><span class="invisible"></span></a></p><p><a href="https://fosstodon.org/tags/cpm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>cpm</span></a> <a href="https://fosstodon.org/tags/interlisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>interlisp</span></a> <a href="https://fosstodon.org/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a></p>

Paolo Amoroso<p>CPMImage is a GUI front-end for cpmtools, the popular suite of tools for accessing CP/M file systems.</p><p>It's similar to WinImage but, unlike WinImage which is Windows only, CPMImage runs also on Linux.

Paolo Amoroso<p>This article is a great biography of Adam Osborne and a history of his endeavours in the computer business.</p><p>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.</p><p><a href="https://every.to/the-crazy-ones/the-rise-and-fall-of-steve-jobs-s-greatest-rival" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">every.to/the-crazy-ones/the-ri</span><span class="invisible">se-and-fall-of-steve-jobs-s-greatest-rival</span></a></p><p><a href="https://fosstodon.org/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a> <a href="https://fosstodon.org/tags/cpm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>cpm</span></a> <a href="https://fosstodon.org/tags/biography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>biography</span></a></p>

Paolo Amoroso<p>This 1982 interview with Gary Kildall is interesting because it focuses on CP/M-86 which is little known.</p><p>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.</p><p><a href="https://computeradsfromthepast.substack.com/p/gary-kildall-has-a-talk-with-pc-magazine" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">computeradsfromthepast.substac</span><span class="invisible">k.com/p/gary-kildall-has-a-talk-with-pc-magazine</span></a></p><p><a href="https://fosstodon.org/tags/cpm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>cpm</span></a> <a href="https://fosstodon.org/tags/cpm86" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>cpm86</span></a> <a href="https://fosstodon.org/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a></p>

Ry<p>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. <a href="https://vixen.zone/tags/cpm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>cpm</span></a> <a href="https://vixen.zone/tags/cpmz80" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>cpmz80</span></a> <a href="https://vixen.zone/tags/tms9918a" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>tms9918a</span></a> <a href="https://vixen.zone/tags/rc2014" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>rc2014</span></a></p>
