PS2 to Tandy 1000 Keyboard Adapter

rebirth2-ay8910-ymz284

The functionally verified RE: Birth 2nd sound card highly refers to the AY-3-8910 schematic diagram of the PS98 project, especially the chip select decoding part and the crossover switching part (of course it also refers to RE1-AY89XX).

rebirth2-sn76489

The design of RE2-SN76489 has been integrated into RE2-YM3438+SN76489

rebirth2-y8950

Functionally verified RE: Birth 2nd sound card. This project refers to RE2-YM2608 and RE2-YM3812. However, these two projects refer to PS98 and SPFM tower. Although I do not have RE1-Y8950, I still successfully designed it.

rebirth2-ym2151

Functionally verified RE: Birth 2nd sound card. This project refers to the YM2151 audio circuit disclosed by SPFM FM Tower. The highlight is that it supports the use of universal dual operational amplifiers (such as NE5532, TL072) under a single 5V power supply. After multiple versions of repairs, Everything is as good as RE1-YM2151

rebirth2-ym2163

The most detailed YM2163 information at present.

rebirth2-ym2203

Functionally verified RE: Birth 2nd sound card. This project refers to RE2-YM3812 (and of course RE1-YM2203). The feature of this project is the addition of a stereo PSG adjustment switch. This function was first used in various sound cards with PSG. MegaMod, the stereo PSG circuit refers to the audio circuit of ZX Spectrum.

rebirth2-ym2413

Functionally verified RE: Birth 2nd sound card. This project refers to the YM2413 audio circuit of the PS98 project. The highlight is the use of differential amplification (instead of the inverting addition used by FMPAC) to mix the MO and RO together and cancel all busses. noise and power supply noise, making this design excellent.

rebirth2-ym2608

Functionally proven RE:Birth 2nd sound card, this project references the YM2608 part of the SPFM FM tower (and of course the RE1-YM2608).

rebirth2-ym3438-sn76489

The proven RE: Birth 2nd sound card supports welding on either of the two chips YM2612/3438. The OPN2/2C audio switching circuit refers to the design of MegaGRRL. SN76489 is also supported, but a second PCB is required to introduce BSEL1 as the chip select signal for SN76489.

rebirth2-ym3812_3526

YM3812/3526 music module for Project RE:Birth 2nd SPFM

rebirth2-ymf262

Functionally verified RE: Birth 2nd sound card. This project refers to the design of RE2-YM2151 and RE2-YM2608. In fact, the audio circuits of OPM, OPNA, and OPL3 (Yamaha dedicated DAC YM3012/3016/YAC512) are exactly the same.

rebirth2-ymf276-288-289

The proven RE2 sound card supports welding on any one of the three chips YMF276/288/289.
