ChatGPT is undoubtedly the hottest topic of discussion in the field of artificial intelligence, and a developer with the screen name yeokm1 has recently built a ChatGPT client that can be used on MS-DOS systems on a 1984 IBM portable PC 5155.


yeokm1 developer wrote and developed a Slack client that runs on Win3.1 3 and a half years ago. This time he tried to develop support for running ChatGPT on a much older platform.

The MS-DOS system does not natively support network functions and the system’s processing power is weak. He conducted development tests on a 1984 IBM 5155 portable PC, attached the following configuration:
Intel 8088 processor with a clock frequency of 4.77MHz
640KB of regular memory
CGA ISA graphics
NE2000-compatible ISA Ethernet adapter
MS-DOS 6.22
One challenge was to find a suitable network API for DOS, using the ChatGPT-for-DOS application written in the Visual Studio Code text editor (tested on a virtual machine running DOS 6.22) to parse the JSON output from OpenAI’s Chat Completion API.
