Thanks! I heard about your work on a MAME forum on bannister as "seanriddle" posted about you
and the great work your doing for the AY-3-8500-1. I cannot imagine the idea of trying to retrace the
die inside the chip as i've read about the creator of the AY-3-8500 (Gilbert Duncan Harrower) that it took about a 1,000 transistors to make the circuit of this chip. For anyone who wants to read the interview of Mr.Harrower done by Nate Lockhart (a few days ago), go here:
And i've noyiced that you responded to Nate's interview and writing that the AY-3-8500-1 has
2,318 transistors ?!?! WOAH!! And if this can help, have you read this post: http://discreteconsoles.blogspot.com/2015/10/emulation-of-ay-3-8500-1-and-clones-soon.html
There's a Pong console that is totally made with TTL's (don't know how many) called the "Palestra-2" made in the Soviet Union. In the post, there is a link to download the schematic of this console.
And if anyone from the MAME/MESS team (especially seanriddle) needs the schematic of the uPD777C (Epoch Cassette Vision dedicated chips), i was able to get my hands on it thanks to the developer of those chips.
And for fun, i've made a Pong clock simulator of the AY-3-8500-1 in 2013 here: https://love2d.org/forums/viewtopic.php?f=5&t=76068&p=156817&hilit=8500#p156817
So keep up the great work you are doing Cole, one day when we will be able to play the games from the AY-3-8500-1 in emulator form, it will be because of the hard work you've accomplished!
P.S., my cat says "meow"! :p (lol!)
