OpenAI’s GPT-4 was revealed not too long ago, so what better way to test out ChatGPT than on an old 1984 IBM PC-XT? Coder Yeo Kheng Meng did just that on the 4.77 MHz Intel 8088 CPU powered machine with 640KB of RAM. Testing was first conducted on a VirtualBox virtual machine running DOS 6.22.
What caused Meng the biggest headache was figuring out how to connect the PC-XT to ChatGPT. Fortunately, he discovered MTCP by Michael Brutman, which was used to connect the PC to ChatGPT’s Chat Completion API. Next, JSON parsing, changing output from a secure to standard protocol, and finding a way around the lack of DOS multi-threading.

Considering this is my first time coding for the DOS platform and on this old IBM PC at that, I was actually impressed by the performance of old machines like this. And before you ask, I did not use ChatGPT for help to code this app in any way. But anyway I decided to ask it,” said Yeo Kheng Meng, Coder and Private Pilot.
