This one is a MicroWeb Touch-1 XT/AT. Kinda.

See if you look up that keyboard you find the Deskthority page on it, showing this.
It's clearly pretty similar, but there are some differences.
Also that one uses a PC/XT/AT DIN5 connector, and this one uses some kind of RJ connector.
This one isn't in the greatest of shape, but considering I got it from the Chuck Colby estate sale, it's surprising it isn't completely water-damaged.
It's got some minor rust damage inside, where the metal clips rubbed off on the PCB.
And the control chip is a C35331E.
It's one of those chips you can find a few places that'll sell you one, but nowhere has a datasheet.
"8647" is probably a date code? 47th week of 1986.
That matches the chip on Deskthority.
And all keycaps removed! These are "Futaba MA series" (aka Futaba clicky switch) switches.
It's got 5 pins connected. AT is only 4 pins, but the PC/XT keyboard is 5 pins. So maybe this is a switchable keyboard?
the Deskthority wiki seems to partially agree with that:
There's a jumper under the tab key, which is theorized to be a XT/AT switch.
SO, what the heck is the pinout? I have no idea what the pinout of the IC is, and nothing to connect this to to spy on it, and no results online for googling the name other than the one that's shown up on deskthority.
Well, the PCB has two other chips on it.
They're both 74-series logic.
We can easily find datasheets for those and they should be sharing power/ground.
green is +5V
and either blue or yellow is GND.
(they both seem to be ground, at least as close as my multimeter can tell.

"I really want to break into Product Management"

"If only someone would tell me how I can get a startup to notice me."

Make Products.

"I guess it's impossible and I'll never break into the industry."

MAKE PRODUCTS.

Courtesy of @edbrisson's wonderful thread on breaking into comics –
https://t.co/TgNblNSCBj – here is why the same applies to Product Management, too.


There is no better way of learning the craft of product, or proving your potential to employers, than just doing it.

You do not need anybody's permission. We don't have diplomas, nor doctorates. We can barely agree on a single standard of what a Product Manager is supposed to do.

But – there is at least one blindingly obvious industry consensus – a Product Manager makes Products.

And they don't need to be kept at the exact right temperature, given endless resource, or carefully protected in order to do this.

They find their own way.
