cr1901 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, CD/floppy disk theory of operation, and the 68k CPU are also on-topic.

also I have to wonder if the SetWindowTitle symbol name is a misidentification
<andlabs>
because that shoudl already be a reserved name imported from user32
<andlabs>
er wait no that's SetWindowText gah
<andlabs>
I keep getting that wrong

<qu1j0t3>
actually more on topic for #avr since i'm currently portin gthe code to avr
<alexisvl>
qu1j0t3: :O
<alexisvl>
that's awesome
<qu1j0t3>
:D
<qu1j0t3>
a compliment from you means a lot!
<alexisvl>
:D
<qu1j0t3>
sadly it no longer uses the YM3014B DACs, but maybe with more study... it could again
<qu1j0t3>
at least it does use orderable parts
<alexisvl>
pfft, it's 2022
<alexisvl>
what's orderable
<alexisvl>
unless you count backorder :p
<qu1j0t3>
:):)
<qu1j0t3>
yeah it's a bit nervewracking.
<andlabs>
nice
<tunixman>
wow those are nice lines!
<alexisvl>
yeah it looks great
<alexisvl>
the vector display itself is interesting. There's a texture to the trace that made me think it was displaying through a storage mesh, but that's a non-storage monitor
<qu1j0t3>
alexisvl: Sorry i should have explained, it has a pretty busy vectorscope graticule on it.
<qu1j0t3>
alexisvl: not ideal, but a 604 and 606 i was testing with are hors de combat
<qu1j0t3>
idk why a 602 would have a vectorscope grat but here we are.
<alexisvl>
qu1j0t3: ahhhh
<alexisvl>
yeah, I see the graticule, it's busier than I'd have expected
<alexisvl>
that explains that :)
<alexisvl>
looks cool tho
<qu1j0t3>
it's an amazing monitor.
<qu1j0t3>
the sharpness does not come through in photos at all.
<alexisvl>
no, it never does
<alexisvl>
CRTs are SO hard to photograph well
<qu1j0t3>
602 is probably my favourite tek xy
<alexisvl>
tek was _good_ at CRTs in that era though. they're all just stupid sharp
<qu1j0t3>
from a lovely-to-repair standpoint too
<qu1j0t3>
yes they are
<alexisvl>
"The trace width is 14 mils at 0.5 μA beam current." <-- hm so pretty typical spec, though I wouldn't be surprised if many exceeded it
<qu1j0t3>
yeah mostly talking about the subjective experience
<qu1j0t3>
just generally unexpectedly crisp
<alexisvl>
these vector monitors are a bit easier to get sharp in general tho bc they can run pretty low beam currents due to slow deflection
* qu1j0t3
nods
<qu1j0t3>
good point
<qu1j0t3>
yeah this circuit drives them at about 55µs for full deflection
<qu1j0t3>
iirc
<alexisvl>
heh the schematic of this monitor is adorably simple, i love it
<qu1j0t3>
or 80µs ... easily tuneable
<qu1j0t3>
alexisvl: It's great isn't it
<qu1j0t3>
i have an HP 1208A that's similar
<qu1j0t3>
hm, i haven't hooked that up to this circuit yet
<alexisvl>
kicks my designs right in the ass :)
<qu1j0t3>
alexisvl: no curvy traces on the pcb bc this mac can't run kicad 6. but gosh it was a lot of work to route and fill...
<alexisvl>
i also like straight, angular traces. my boss describes my layouts as "brutalist" :D
