I wrote a PCB design program in Assembler in around 1990.
It was 330,000 lines.
The page size then was 64K so I had to mess around with segment registers to access other memory.
The max I had to work with was around 512K.
There were no graphics libraries I could find so I had to write software to draw straight into the video memory.
Great fun.
