I made a new logo for https://github.com/fsmv/daemon what do you think?

Also I think I'm going to document calling the binary dmon if you want to avoid conflicting with the other binary called daemon. So this fits with that :)

Some more PC pictures now that I'm done upgrading/fixing it

This is assembly code I wrote to test my method of loading code onto it. It's a COM file being run by DOS 3.3

Replacing some 1983 ram chips this weekend. Some of the chips on the card are failing now.

Kinda funny that this card I bought has a bunch of different timings for the chips and yet it works.

These are 16k 1 bit memory chips so 8 makes 16kb and 1 extra for parity.

I ran x86 assembly I wrote on my laptop on my 1981 IBM PC!

I had to write a .com file and run it in DOS. I'm going to write a little installer .com file that writes bootstrap-os to a floppy for booting.

Yessssssss I have a fully working original 1981 IBM PC setup now! I even managed to boot a very old looking DOS 3.3 floppy.

Tomorrow I'll try my setup to transfer files from my modern PC. After a little bit of code changes I'll have my text editor and lisp code fully compatible and run it on this (currently my code is only compatible back to 1984 PC AT for minor reasons).

I'm so happy. It took a lot of effort to find the monitor.

The IBM PC in 1981 had ctrl+alt+del.

Finally got this refactoring working. I had to move around all the memory in order to keep the lisp state safe but now I have a real REPL working!

I wrote this text editor and lisp interpreter in 16 bit x86 assembly and it BIOS boots on real PCs!
