Who says you can’t teach an old dog new tricks?
Wow! I did’t think that the IBM PC Jr. would even be capable of running a TCP/IP stack let alone a small, low power web server. That’s pretty dang impressive.
At 33 watt (original power supply) it’s extremely inefficient though. But considering it’s 4 decades old; 33 watt was probably very economic back then.
33 Watts including the crt?
Wrote a partial tcp stack that ran on a cortex m3 microcontroller, it could marginally serve web pages. Remember tcp was basically designed when the 386 was a beast, memory is the main limitation.
That was my first computer! I spent hundreds of hours with that BASIC cartridge. Now I’m getting all nostalgic.
Right there with you. Learned to read, spell, game and code on that little work horse.
A web server is just a program that communicates with a network. I’m running web sites completely from chips as large as the fingernail of your pinkie.
Exactly, and processing power in small chips is insane now. You can run Doom on a damn bios chip now.
Hell, my esp8266s can run a basic web server and login portal without breaking a sweat.
I’d be surprised, but I remember seeing a website that ran from a scientific calculator iirc. It’s still very fascinating though.
found it, looks like it’s been taken down though.

Does it run an online version of Doom?
Its not powerful enough. Might do wolfenstein tho.
If doom can run on a thermistat, then it can run on a IBM PC Jr.
Im telling you, it literally can’t. You need a 486 or better, and it doesn’t have that. Just pure instruction set problem. Also below the min ram requirements.
Well it runs on the commodore 64

Not sure that counts as running lol
Since it’s a webserver running on this, would it be possible to deliver a JavaScript implementation of DOOM?
You could, but then it wouldn’t really be runing on the pcjr
