vedge Posted August 26, 2008 Report Posted August 26, 2008 HiI also have 9 AY 3 8910 units that are sitting in a tube, so it might come in handy. Quote
jackies Posted September 2, 2008 Report Posted September 2, 2008 This is sweet!I have one AY 3 8912 laying around somewhere...May the 8 bit force be with you!!! Quote
lemonhorse Posted September 3, 2008 Author Report Posted September 3, 2008 Just to inform you: Mike is on vacation till the end of this week.

lemonhorse Posted September 9, 2008 Author Report Posted September 9, 2008 got a mail from mike today - he told me that the two AY 3 8912 test boards are almost on the way. Quote
lemonhorse Posted September 14, 2008 Author Report Posted September 14, 2008 Thanks to nILS and PCB Mike! Here is the AY 3 8912 BOARD (V1.0) => http://www.midibox.org/dokuwiki/midibox_ay_3_8912_board :) Quote
Theta_Frost Posted September 14, 2008 Report Posted September 14, 2008 Yeaaaaa! :D Good job lemonhorse! I can't wait till I'm rocking my 8-bit symphony with this, SID, and POKEY! So cool! :)also any idea when I might be able to get my hands on some of these boards? Quote
lemonhorse Posted September 14, 2008 Author Report Posted September 14, 2008 any idea when I might be able to get my hands on some of these boards? I hope soon. In my view there is a little issue with the A, B and C Pad size.But when the board is available I will post it here of course. Quote
Theta_Frost Posted September 14, 2008 Report Posted September 14, 2008 cool, I will for sure make this sometime in the future! Quote
Theta_Frost Posted September 17, 2008 Report Posted September 17, 2008 Hey lemonhorse can you post the parts list for the AY board? I'm gonna try a vero one and it would be nice to know! ;D Quote
lemonhorse Posted September 17, 2008 Author Report Posted September 17, 2008 Hey lemonhorse can you post the parts list for the AY board?http://www.midibox.org/dokuwiki/midibox_ay_3_8912_board updated (Parts List). Here is a Picture of my Prototype ;D : Quote
nILS Posted September 19, 2008 Report Posted September 19, 2008 My AY-3-8912 says to say "bleep bleep bloop" ;Dedit: Actually, why doesn't he just say "hi" himself... ;-) Admittedly you can only get so far with random values in the registers but hey - it's a sign of life. Oh yeah, and ignore the -30db noisefloor it's not from the AY which is amazingly quiet but from my soundcard...ay.mp3 Quote
buhler Posted September 20, 2008 Report Posted September 20, 2008 oh nILS, always one step ahead of the game! ;D.... Quote

nILS Posted October 1, 2008 Report Posted October 1, 2008 Since lemonhorse asked me to take some pics of my AY and I miserably failed to do that so far, here's a little compensation :-)Little mbAY-3-8912 DemoDrums are VSTi, added a some reverb and delay to hide the noise of my soundcard ;-) Quote
buhler Posted October 2, 2008 Report Posted October 2, 2008 that's great! ;D i just need to find a PSU for this and my MBFM... :'( i have the boards and such done i am just having a serious problem figuring out the PSU situation. the same PSU would work for both wouldn't they? Quote
nILS Posted October 2, 2008 Report Posted October 2, 2008 You can easily leave out the opamp buffer board for testing. Just connect all three outputs via 10k resistors and add a pulldown of 1k-5k from that signal to ground. Quote
lemonhorse Posted October 2, 2008 Author Report Posted October 2, 2008 the same PSU would work for both wouldn't they?yes. Quote
