That implies there is a point he would.
So you have never tried to hook up a scanner?
I hate investing time into making parts because they always seem to not be usable in any later version.
Replacement for pulse or ANOTHER layer on top?
I gave it an image of a table of numbers and stuff, asked it to digitize it for me, it came back with a goofy art sketch....?
Wait, did you try this...
Ah, all my part definitions are obsolete AGAIN? I feel so surprised.

"one wire" Dallas, it uses 2 wires..
Static go BZZZT on your SSD. I dont miss that.
Well, it contains text messages in 5 languages (atleast) containing names of the months and 2 digit numbers from 00 to 59.. I have seen systems where all the user software is just config script.
Check out the offset tho, whats with that...
I tried a few tools and completely failed to be able to get them to id the processor.

2018: wall pencil holder. I think this is posted on thingiverse...
huh, I guess the CH32V003 is fast enough to do on-the-fly i2c address remapping.... drat, I wanted to use a CPLD....
ok, the image is odd, its got a huge 0xEA header, but I do see what looks like it could be a vector table...

(note the "3C" followed by 2 bytes, then repeating) 5 vectors.

I wonder if this memory is mapped funny.
THIS is the ROM from a newer model nortel digital phone. would anyone like to guess what processor the firmware on it will be for?
HOLY WIND STORMS THERE ARE TREES BREAKING EVERYWHERE!

here's the schematic, it's exactly the same as the model 1's onboard design, just duplicates it for each channel instead of mixing them down to mono.

whole thing fits comfortably into a 23mm x 13mm (0.9in x 0.5in) board if you can do smt soldering.

i can't offer tech support, but have fun 💜
