A while back I bought two of those Maclocks with the intention of modding one into a tiny Mac.

    I should post about the latest #retrocomputing project I started.Problem: I'd like an open-source, self-hosting C compiler on 8086, that supports the large memory model, overlays, and enough C89 to build Lua.This seems to not exist! K&R is much more common in this size category. Around the time of C89, many compilers bloated to the point of requiring a 386 or better host, though they could still target 8086. The 8086 holdouts were, in general, commercial products that never got a source release.One notable exception was DeSmet C http://www.desmet-c.com. It seems to have started life as a commercial PC fork of Bell Labs PCC, a small and sturdy K&R compiler. DeSmet 3.1 added "draft ANSI C" support, but this is incomplete, and riddled with code-gen bugs. This version later found itself on Github as OpenDC https://github.com/the-grue/OpenDC.Aside from all the bugs, this is a pretty cool package: its dis/assembler, debugger, text editor, and some other utilities were also open sourced, and it runs on an 8088 with 256K RAM and two 360K floppies.The OpenDC person did a good job packaging things up into an easily buildable form, and fixing syntax errors that probably came from running the sources through a different compiler version than expected, so... yes, it does indeed build and self-host... and I've done this on my Book 8088.So now I will try to fix the bugs and add the missing C89 features. There are many, many of both... gulp.

    @simonzerafa The Utah teapot! 💚 Used as reference for an early 3D model with important characteristics, such as a branching spout.

    @amberisvibin Coherent also supported the 286 (and possibly also the 8088), so a 386SX should work just fine. More information about Coherent and the full manual here:https://www.nesssoftware.com/home/mwc

    News from the #Floppy #Museum! A friend of mine, fusion[1] from #OS2Warez, has written a tiny wrapper for #BBS #door programs so I can run them without needing a full-blown BBS. Combined with rlfossil, a telnet-to-serial-port emulator for DOS (yes, really!), you can now read and write messages in my little forum! Just telnet to floppy.museum on port 8023 - I recommend using #SyncTERM or some other client that implements the IBM 437 codepage, or 850 in a pinch. The experience should be fairly period-correct, something akin to a 1200 baud modem based on my testing. And just a reminder: This is a 286 machine, which also runs a web server, an IRC server, an FTP server and all of the above at the same time. It's not fast, but it gets the job done. Also: Only one node at the moment. If it's busy, try again later! Consider it an early beta, for the moment! :D [1] https://dcclost.com/ #RetroComputing #Why #Patience
