Worst keyboard controller ever

I had my Tulip ATK 030244 (Monterey K102) apart earlier, and for the first time I pulled the plate out. I found this on the bottom of the PCB:

This is the actual IC:

What the rubbish on the back of the PCB is for, I have no idea. Reminds me of Jeri Ellsworth's tale of getting the C64 Direct-to-TV manufactured, only even more drastic.

Nearly 50% of the switch uppers (upper shell, return spring, click leaf and slider) are now in my Dell AT102:

I'm also using the doubleshots from the OK-100M instead, as they're far nicer than the lasered keycaps from Dell. However, in addition to obvious mismatches (1u vs 2u backspace, space bar, ctrl/alt etc), the caps lock keycap stem is slightly offset, so it won't fit. (I left it in that unfinished state to illustrate doubleshot vs lasered, just so I can slag off laser etching as I hate it.)

It strikes me as a patch. Like they had the PCB manufactured in numbers, and then found a bug. It had to be fixed cheaply, hence the dirty patch and lousy, time constrained hand soldering.

I gathered that (cf Jeri Ellsworth and the C64 DTV), but why are they wiring half the controller back to itself using a bus bar and a load of capacitors? I wouldn't have thought that you could screw up addressing a keyboard matrix that badly …

It's a weird keyboard. The plate mounting holes are stamped out in pairs, which line up with matching pairs of holes in the shell:

They only tapped every other hole, too, unless they're self-tapping the holes (it's only soft plastic, after all).

It's solid and reliable though, but I want blue Alps in a 105-key ISO keyboard :) Sacrifices have to be made.

That's what a real patch looks like! Today's software patches is just not the same thing.

I'm resisting posting pics of another "controller", that is likely more awful than this...
No patch job, but it needs one...very badly.
A keypad where 6 of the 16 keys are not even connected to the controller...at all. And the "controller"...does pretty much nothing.
