cr1901 changed the topic of ##yamahasynths to: Channel dedicated to questions and discussion of Yamaha FM Synthesizer internals and corresponding REing. Discussion of synthesis methods similar to the Yamaha line of chips, Sound Blasters + clones, PCM chips like RF5C68, and CD theory of operation are also on-topic. Channel logs: https://libera.irclog.whitequark.org/~h~yamahasynths
<Lord_Nightmare> Foone: C. P. Guzis... is that chuck guzis of sydex/teledisk/anadisk/22disk fame?
<Lord_Nightmare> Yes. Yes, it is.
<Lord_Nightmare> "Written in October 1986 by
<Lord_Nightmare> 153 North Murphy Ave.
<Lord_Nightmare> Chuck Guzis
<Lord_Nightmare> Sunnyvale, CA 94086"
<Lord_Nightmare> i do not believe he still lives at that address.
<Lord_Nightmare> yeah, he moved to oregon sometime around 1990 I think?
<Lord_Nightmare> he is/was on the cctalk mailing list
<qu1j0t3> still is
<Lord_Nightmare> chuck guzis is also responsible for the (earlier, somewhat flawed with the newer ASIC?) version of the PAL equations for the 'short' sound blaster 2.0 card PAL used for the SAA1099 chips
<Lord_Nightmare> I think someone fixed the pal equations later
<Lord_Nightmare> i.e. chuck reverse engineered them
<Lord_Nightmare> i don't think chuck fixed the equations but i could be wrong
<Lord_Nightmare> iirc the problem was the pal .jed he produced wouldn't work correctly with the later ASIC (with an A at the end of the part number) on later/most sb2.0 cards, it would only work with the older asic
<Lord_Nightmare> due to some timing edge cases
<NiGHTS> William D. Jones sur Twitter : "Oooh, there's a name I know. You'd be hard-pressed to find someone who knows more about vintage PC hardware than Chuck Guzis. He also (AFAIK) wrote the original AT2XT keyboard converter impl: https://t.co/hSn0iCLxfJ… https://t.co/rBbmdON2xx"
<cr1901> He built a 286 system (non-PC clone) called the Durango Poppy in the mid 80s. He isn't sure any still exist :(.
<Sarayan> That reminds me, it's about time I do puppy eyes at Foone again.
<Sarayan> Even if 14 days of idling makes the answer probability low :-)
<Foone> I can answer but not usefully: I'm currently in the middle of too many projects to really devote any time to setting up a microphone and floppy drive arrangement. feel free to put a calendar notice to ask me again in a couple weeks
