Hey, slowcoder . . ..

I think dosraider needs some Midol....


COM was an executable file, remember? if you had three files, all named the same, like:
test.com
test.exe
test.bat

DOS would "look" for the com first, then the exe then the bat..... I think it's still that way...

And.......for dosraiders enjoyment.....heh

Hard to believe, but one Quickbasic was considered a "High end" programming language......

Biggest knock was the large file size - like a stand alone 35-45k was large - and it was slow in those old systemd compared to assembly . . ..

Remember Z80?

Hint: 8088's powered the XT's

Hardware interrupts.....256 - or is it 255 - tiny programs embedded in the microprocessor that was the core of everything a computer does.....

I was lucky enough to work in the Silicon Valley in the late 70's through the 80's.....

Some for my accounts were Intel, National Semi, AMD...... Got to see how thay made the chips, kept up on all the latest breakthroughs...

I remember when National came out with a 5 inch wafer! No kidding...that was a BIG deal back then....

Oh yea...in the early 80's, my biggest account was Shugart. They made floppy disk drives....... The founder went on to start Seagate....

Anyone out there remember Amdahl systems? They were the only competitor to the large IBM mainframes.....
