<fseidel> Foone: it's worse than that, you have to waste time writing an address to the video hardware every time you want to access a RAM address that isn't an increment of the previous one
<fseidel> these are the memories they used: http://www.unige.ch/medecine/nouspikel/ti99/groms.htm

<emeb> hola!
<cr1901_modern> Hello! Recently there's mostly been discussing about old nonvolatile storage like EPROMs and EEPROMs :).
<cr1901_modern> We'll get back to talking about FM stuff once someone brings it up of course :P
<emeb> heh, following along w/ wq's twitter adventures.
<emeb> so yeah, a few years ago when I was just getting fired up about ice40 stuff I did a multivoice FM synth modeled on yamaha that ran in an Ultra part. lotsa operators that could be hooked up in weird ways, controlled over SPI and output I2S to a cheap DAC.
<emeb> I should probably tidy it up and put it on github sometime.
<cr1901_modern> I'd be interested in seeing that

<cr1901_modern> ej5: Someone decided to reignite the "are FPGAs emulation" discussion again on hellsite, so that's why your
<cr1901_modern> "losing the recipe" tweet is getting some attention
<ej5> i saw
<cr1901_modern> Sorry about that- I wouldn't have linked to it if I thought everybody was going to start faving it and exploding your notifications :P
<ej5> no worries, it doesn't bother me
