ChanServ changed the topic of ##yamahasynths to: Channel dedicated to questions and discussion of Yamaha FM Synthesizer internals and corresponding REing. Discussion of synthesis methods similar to the Yamaha line of chips, Sound Blasters + clones, PCM chips like RF5C68, and CD theory of operation are also on-topic. Channel logs: https://freenode.irclog.whitequark.org/~h~yamahasynths

You didn't add that constraint. You asked "is there anything that runs on the 5150 but not the 5160?"

will stop being a pedantic asshole now

Estimate delivery between Feb 1 and Feb 19 :D

Foone: Unfortunately I can't remember the details offhand, but PS/2 is open drain. 3.6V is a reasonable upper limit for pins on 3.3V micros. Use a pullup resistor up to 3.3V rail.
<cr1901_modern>
The resistor dividing action between 5V and 3.3V should give you an okay voltage
<Foone>
good to know.
<cr1901_modern>
This is what I did for my AT2XT keyboard converter
<Foone>
yeah. HP did a bunch of things like that. GPIB (or HPIB) is very generic so they could easily support more than one storage type in a single box
<Foone>
I think there's combination floppy/CD ones and CD/HD too
<cr1901_modern>
HD == hard disk?
<Foone>
yeah.
<andlabs>
heh
ValleyBell has quit [Ping timeout: 260 seconds]
ValleyBell2 has joined ##yamahasynths
<Foone>
not HD-DVD. that'd be weird
<Foone>
I don't think you can get those in HPIB
<cr1901_modern>
Right... wasn't thinking critically here. I thought they were selling full computers that were floppy/CD only :P
