Finally... The video about first fully tested debug module - SN76489A / SN PSG / 3-voice PSG / Tandy sound . Video is in Russian, as usual. But automatically translated subtitles can help with that. https://youtu.be/-4YIZy-07sI And additional video, test of this module in 8 DOS games: https://youtu. …

One of those cheap heat map guns on ebay? Exact opposite. Flir E4. Bought it recently. I don't understand why you use a Buffer and @decoding for each chip. Only some buffers and a CPLD for @decoding cad do everything and it will save so many space. I do not want any programmable device on the …

Re: FMonster, the monster of sound synth

I've finally got to test the "3-voice PSG" board (SN76489)! And it works just fine. Of course there were some minor bugs as: - I've forgot to connect power to one logic IC that provided clock for SN76489 - Some capacitors and resistors needed to be added to reduce noise level - I've connected LED to …

Re: FMonster, the monster of sound synth

Two more months passed... I've fixed some errors in some blocks and rearranged those on the board. New order (left to right): SN PSG, 2xSAA (CMS), 2xOPL2 (2xAdLib, SB Pro), AY (CSM), 2xSID (2xSSI-2001, DuoSID), OPL3. Filename fmonster_2019-12-12_01.png File size 183.38 KiB Views 321 views File …

Rainbow Arts Soundman also listen to 0x300 maybe Voice Master too? I've tried to decode and simulate address decoder of Rainbow Arts Soundman from photos. That's what I've came up with. ports_RainbowRunner_2019-12-09_01.png ports_RainbowRunner_2019-12-09_02.png ports_RainbowRunner_2019-12-09_03.png …

Re: FMonster, the monster of sound synth

Now working on some minor optimizations of "big board": - tidying up silkscreen - tidying up shared logic (Reset inverter, /IOR and /IOW repeaters, high-address decoder) - adding debug LEDs (reset/power rails/MIDI TX-RX) 2019-11-21 00.54.16.png Board now decodes 15 of 16 bits of address bus (instead …
