Good afternoon! I collect older computer books and software. I recently purchased a used copy of Steve Rimmer's "Graphical User Interface Programming" to add to my collection which includes a couple other titles by this author:
"Bit-Mapped Graphics"
"Super VGA Graphics Programming Secrets"...
Not sure if anyone is still using PC-MOS/386, as it had encountered the crippling date bug on 8/1/2012, but I discovered the bug and have fixed it in our Open Source repo here:
https://github.com/roelandjansen/pcmos386v501
I also created a binary patch in the 9-user image in the repo in case...
I am currently working on the source for PC-MOS/386 which is available on github here:
https://github.com/roelandjansen/pcmos386v501
Having not used this OS (but having years of experience programming DOS) prior to discovering the github repo and spending countless hours playing around with it...
