I haven’t heard of Jeri Ellsworth in a while but every time her name pops up around my news feed is because she’s done something awesome.
This time she has made an hybrid bass guitar-SID chip thing, controlled by an FPGA and using a real SID chip to play the sounds (from both the strings and the Commodore keyboard).
Enough blabber, check out an interview and demo on the first part of this video:
The whoe idea of this project, is to make a mini sythn based on this chip, the following is the schematics of all the connections. I used a TTL Crystal Oscillator of 2Mhz to provide the needed clock of the chip, and a 595 to reduce the number of the DATA pins needed for the registry address and data input to generate sounds/envelopes/noise etc.
via Arduino playground – AY38910.
Now you can use your 16-bit Sega’s FM (and PSG) sounds in your modern audio rig!
For 85 AUD (~ 87 USD/67 EUR) you can get this interface/cartridge combination that will let you control your Sega through MIDI from the MIDI sequencer of your choice.
First units are scheduled to be shipped “on or before Thursday, 17th May, 2012″.
Head over to little-scale’s website to pre-order one of these fantastic devices!
Sorry for too long preface/introduction ;) but it was my very _first_ contact with ZXpand module for ZX81 computer (32Kb or RAM, SD-card instant loading plus additional AY-interface in standard of classic ZX81′s ZonX AY-interface from 80s).
It is really ZX81 playing music via AY chip (well, actually its Japanese version: YM). You can get both modules from RWAP Software: http://www.rwapsoftware.co.uk/zx812.html
