You guys are awesome! It’s almost like history is being rewritten. A sort of sci-fi revisionists version of the original PC! Thank you!!

My linked page is actually my continuation of the reverse engineering to its logical conclusion: a crude player and a crude decoder. The player is slow and unable to hold synch; the decoder outputs to an unwieldy format of bmp-per-frame+separate wav audio. The player needs SDL and both need SoX in order to play or mux the audio. I have successfully made an AVI out of the output of the decoder, using Virtual Dub under WINE. It came out great.

Yes, email me if you want the ROM dump from my 5150.

“Something for the wiki, yes?”

Be my guest. BTW, where can I find the IBM BIOS ROM codebook? Do you rip them from the ROM in software? You must have a software copy somewhere for the encoder?

Sweet Lincoln’s Mullet!

Yes, that is all 100% correct :-) And yes, the compressor takes several seconds per frame on my Athlon 2500+. My original idea was a 1-to-1 match, but gODjR (the other person mentioned in the docs) had the idea to do subsampling and much better dithering, so the quality props go to him.

The IBM BIOS ROM font is essentially the codebook. It is important to use the actual IBM ROM font as the conversions were done specifically with that font (this is what sets it apart from aalib or libcaca, which don’t take actual font rendering into account.

Something for the wiki, yes?
