Spontaneous numlock

I think before that I was writing something to make composite images of cover scans of old electronics magazines like Popular Electronics and Radio Electronics because I found PDFs online, 50 years of each.  https://worldradiohistory.com/Popular-El...-Guide.htm  They have Byte back issues and several others too.

Those are amazing archives!  Now, if I only had a couple of extra lives to read everything that's freely available these days...

There are ones labelled ansi and iso but there's also fw_tp_update.hex and tpfw.bin.

As far as I know, the former is the "helper" firmware that gets flashed to the keyboard in the first step, and the latter is the actual touchpad firmware that gets flashed in the second step.  The touchpad is connected to the keyboard via I2C, so the keyboard "forwards" the firmware to the touchpad in the second step, using the "helper" firmware flashed to the keyboard in the first step.
