TechHeart [me!] posted another video this weekend... still enjoying the Dolch PAC-60 486/DX66 machine and MS-DOS completely packed with softwarez... so, we take a left turn and jimmy Minix 2.0.4 on the machine. It was fun, and interesting to [finally] experience Minux - the OS designed by Andrew Tenenbaum only b/c AT&T was breathing down his, and other professors, necks telling them they couldn't continue teaching Unix to students... without Minux, Linus may have never gotten the bug to develop Linux - what would the world be like built on top of FreeBSD rather than Linux??? We'll never know - because of all these pioneers...

For now, watch an amateur figure out how to finesse the OS onto hardware that most humans have forgotten about - but is still teaching me in 2024. Come along, if yer ok with YT...

Some guy built a homebrew 4 mhz CPU with TTL's running Minix 2.

telnet to magic-1.org as guest:magic

specs:

http://www.homebrewcpu.com/

I already got to run frotz with a downloaded calypso.z3
(libre/free licensed text adventure) I uploaded. It
runs great.

this is so cool. i always wanted to build a pc from scratch.. though i suppose what i really always meant when i thought about it was to build
a motherboard and all that myself.. that guy is next level!

I'm tempted by some of these CP/M homebrew kits out there - I don't know
if anyone made an offline reader for CP/M, though. That would be the
one thing I'd need in a text-mode computer.

so i was going to post about how the qwk format is pretty simple .. so you could probably whip one up.. but then i got it into my head to prove it
myself heh. i got it to the point it can read some messages with a little
help from unzip and an emulator so it's pretty artifical but:

## CP/M emulator
https://github.com/jhallen/cpm

since it's obviously not a real machine, the extent of my verification is "authentic turbo pascal 3.0a for CPM-80 works on it .."

you can just run ./cpm after it's compiled and CP/M will "see" whatever is in the current directory.

## turbo pascal 3.01A
https://winworldpc.com/product/turbo-pascal/3x

i unzipped the disk01.zip into a folder and then moved the cpm emulator
binary into that folder.

you run the tinst program and for the terminal select ADM 3A and select
NO when it asks if you want to "modify this definition", then set the
operating frequency to 4. then you can just quit tinst.

when you run 'turbo', you can press Y to include error messages (seems we
have enough ram..) then press E to select the file. it'll drop you into the editor. the editor isn't great. press Ctrl-K then D to drop back to the menu. now you can press O then C to make turbo generate .COM files, and then Q to
go back to the main menu. finally press C to compile.

i have a feeling crap like that is why turbo pascal 4 was a rewrite.. sadly this one is the last to support CP/M.

## qwkread.pas!
https://kirin.dcclost.com/~alex/qwkread.zip

to test you'll need a MESSAGES.DAT file from inside your QWK file (it's
just a zip file) in the same folder.

currently it scans through the whole MESSAGES.DAT file as if it were one huge message base. enter/space/n goes to the next message, p for previous, q to quit, etc

it looks like there's an unzip for CP/M here: https://github.com/agn453/UNZIP-CPM-Z80

but i didn't test it. with that and a dialup/telnet terminal of some sort
it should be possible to read messages now :)

.. assuming it works on a real machine
