This was like a time travel!!
Good old days of writing small utilities directly using Debug and modifying the disk sectors etc etc!!!
The Ralf Brown's Interrupt List was the bible for me... It went on until late 2000s is when I moved out of ASM to C.
Now fiddling with Golang and Rust, but anytime would prefer C or ASM or C with ASM.
Please don't jump on me as I've been primarily in the System's programming and in Information Security for my entire life. No other lang supports me like C / ASM.
