Coding x86 Pong as a BIOS extension is fun!

Описание: In this video I code up Pong for the IBM PC XT 5160 and get it running from a ROM socket on an ethernet card that doesn't even take an RJ45 plug.
Join me on this journey as we go through the hurdles of making this classic game as a BIOS extension even though we don't even have access to the most basic I/O and timer interrupt routines.
If you ever wanted to learn programming for the 8088 CPU, take a look!

Check out my new project - the 65uino if you'd like to see what a 6502 computer in an Arduino form factor would look like!

If you have an interest in digital electronics, integrated circuits in DIP packages, or retrocomputing you've come to the right channel. This is part 4 of my video series on my IBM PC/XT but expect to also see modern+retro hybrid projects, with 8088 CPU's 6502's, 8051's and the whole support ecosystem around it.

Part 1:    • Fixing an IBM PC XT 5160 Motherboard   Fixing an XT Motherboard
Part 2:    • Building an IBM PC XT from SCRATCH   Keyboard adapter + MS Basic
Part 3:    • Pong on a PC/XT with NO operating system.....   Running code from a ROM on an ethernet card
