people I can tell you: spending a sunday noon reading about k8s stuff isn't quite the same than spending the same time doing retro stuff *yuck*

hopefully I get to have more time over the holidays to work on my projects again.

Anyway: in the meantime, I have a link for you CP/M people out there. If you would like to use good old #Kermit for your online needs I have provided an adapted version for #rc2014 #sio2 and #ctc

Good Morning, #RetroComputing crowd!

I'm doing a litle show-off of my recent coding in #DXForth on my #rc2014 - I'm currently in the process of creating a collection of words to allow for easier access to several RC2014 hardware modules, including #SIO2 and the #I2CBusMasterModule

As part of this, I've written a very simple terminal program, similar to the one I've written for the #I2C based #SC16IS750 #UART so I could test my code.

The result is SIOterm and you can watch this very basic terminal program connect to #rc2014bbs

So here's the repo containing the #Citadel #BBS CP/M source code for version 2.10 including the BDS C 1.4 version (in the contrib folder) required if you want to re-compile the binaries.

The most important file in the repo is CTDLCNFG.SYS which has been adapted to work on port B (0x82) of your #rc2014 #sio2 module.

In fact, you can use that file and a binary release of version 2.x of Citadel for CP/M and just run the CONFIGUR.COM tool and you're ready to go.

Repo's here:

Currently a competitor in #MinCup23, #Quartz is a #crystalline form of silicon dioxide (#SiO2) with a trigonal #crystal system that, ideally, results in the growth of a hexagonal column with pointed ends, but nature rarely allows this, as this #Macro #image demonstrates.

#Amethyst is #quartz #crystal that has been colored #purple, often due to inclusions of iron in the crystal.
The #Macro #Photograph shows several small, partial #terminations, where the crystal comes to a point.

#Quartz is a #crystal form of #SiliconDioxide (#SiO2) in a trigonal crystal system.
Other #mineral forms of silicon dioxide exist, but quartz is probably one of the most common.
Other things can be included into the crystal, or the crystal structure can be deformed, both of which are forms of #flaws in the crystal.
