Quick update to my sub site with the peripherals I've designed and released for use with RC2014 systems and compatibles with the RC style expansion connector.

https://2014.samcoupe.com

- Added the option to include 'SAM Revival 11' with the new SAA1099P Soundchip Interface. If you're curious about sound on the SAM Coupe computer, which uses the SAA1099P, this back issue of SAM Revival magazine focuses on sound on SAM and includes a 19 track audio CD.

- Added more community links.

SAA1099P Soundchip Interface for use with RC2014 systems and compatibles with the RC2014/RCbus expansion port.

Option now on the website to include issue 11 of SAM Revival magazine with the interface for a look at sound on the SAM Coupe computer (which uses the SAA1099P soundchip)

🚨 New Release - SAA1099P Soundchip Interface for RC2014 and compatibles.

The SAM Coupe has been my computer of choice for the last 32 years so bringing its sound chip, the Philips SAA1099P, over to the RC2014 and compatible ecosystem is a no brainer, especially following a request asking if it was possible, so here it is!

The SAA1099P can considered to be similar to using two AY sound chips: It provides 6 sound generators (31Hz to 7.81KHz). 2 noise generators and 2 envelope controllers. Separate volume for left and right volumes of each channel. On the interface the I/O port used can be selected with jumpers to avoid clashes with other hardware you have, as well as for using multiple cards in the same system.

In the video the music playing is from the 'Lyra 3' megademo on the SAM Coupe, by the legendary chiptune musician Ziutek from the E.S.I. demogroup.

improvised by ear and incorrect potato chip tune cover of the track from the social network movie.

I just made it up as i went after a point.

Cool bit of chip tune. If you're an Atari ST in 199X and someone added filters to you.

Released in July 2020:
GRAPHIC OLED Interface
- Add a 128 x 32 OLED module to your project.

Released in September 2021:
ZX TRUE TONE (ZXTT)
- 1.7734MHz Clock oscillator for use with Ed Brindley's YM/AY Soundcard.

Also available on my Tindie and eBay stores - see profile. Plus much more information on: https://2014.samcoupe.com

... spent half the weekend trying to find out why I wasn't able to play a musical scale on the #ay89xx despite having all the formulae for caluclating the tone period implemented correct. some notes were played correctly 🎶 , others sounded like a fart ... 💨

turns out that I did 8 bit masking when I should have done 16 bit masking for the 12 bit of the coarse tune/fine tune registers ... *doh* ... 🤦‍♂️

An interesting use for the RC AY/YM soundcard with the ZXTT to generate DTMF tones here:

ZXTT is my add-on for Ed Brindley's RC2014 card to use the AY-3-8910/12 / YM2149. Released in August 2021 the ZXTT clocks the soundchip at the same exact frequency as the ZX Spectrum 128K computers, so if you're playing back ZX Spectrum music it sounds pitch perfect!

The small ZXTT circuit board, in funky purple colour.

There are nine General Instruments AY-3-8910 sound chips (or compatibles) in this room.

AY3-8910 and YM2149 make a valiant attempt at doing a bit of the loader music written by Rob Hubbard for the 1984 game sanxion. Not bad for these humble and in comparison to the SID inferior sound chips. I'll come back to this when the rig is free and do the whole thing.

#soundchip #c64 #sanxion #robhubbard #commodore64 #ay38910 #ym2149f #eurorack #chiptune

AY3-8910 tries to do SID voice. Syncing the internal modulator to the bass note periods for pretend pwm. Not bad at all for the humble AY without resorting to the intense cpu control of the volume registers, as might be found in much demoscene stuff.

More AY3 / YM2149 sound chip action. AY300 and YM300, each as a three voice stack, with some SID drums as the driver. Lots of lovely trills when it gets going and some buff octaving C64 style bass line action. The kind of tune that'd definitely have had the telly cranked in my school daze. It's awesome👾🕹📺🙂

@robertprice Good to meet you at the show Robert, enjoy your tunes! 😄

I sold out of the handful I took to the show, popular little things! Anyone else after the ZXTT grab one here:

I never expected Rob Hubbard's Commodore 64 SID music to sound this good on an Atari ST without using the DMA of the STE😮 It is just using the YM2149 and timer effects.
Amazing achievement by the demo group Cream.
