My first machine:
The AT&T PC 6300 back in 1984. The first one to be IBM compatible. It used GW Basic and featured a single 5.25 inch floppy drive.
Some stats I pulled off the web:
CPU: Intel 8086
Speed: 8MHz
RAM: 128KB
ROM: 16KB
Graphics Mode: 640 x 400 monochrome
I used to to type reports for school and play Ninja.
Imagine this, but all in shades of green.
