Only weird thing is that the Telegram taskbar icon is now black for some reason lol (it used to have the normal blue circle behind it)
Good news! I might not have to tear out the whole board after all! I found this in one of the repair/modification guides for this radio that are floating around the Internet (thank goodness the radio was so popular):
This is the radio, by the way: the Kenwood TS-930S, an HF transceiver from the '80s, shown here upside-down with its covers removed. I _really_ hope I don't have to remove that PCB—there are so many connectors and wires…
And I'm a data hoarder, so these are all probably gonna live on my computer forevermore now :P
After struggling with all that for a good while, I finally got the floppy drive free, tested the voltages, got the replacement plugged in. I got everything loosely assembled enough to do a test power-on…only for the laptop to not POST. I think I found the issue though: looks like a kersploded capacitor =/
I may have solved the display mystery though; the LCD screen plugs into the motherboard with this cable that you have to be careful to unplug when taking the case off. The connector isn't keyed, so I may have just plugged it in backwards last time heh
I opened it up first thing because I wanted to check the floppy drive model to make sure it wasn't a 720k drive or something. It isn't though; the Teac FD-235HF is a pretty ubiquitous 1.44 MB drive
Huh, apparently I took the hard drive out and left it last time I had this opened up. No idea where it could be now. It just kinda floated over the motherboard there, screwed into the sides of the enclosure. Standard IDE connection but a weird miniature power connector
At first glance I couldn't see what use the Fn key had, but then I noticed that there are numbers on the front edges of the keycaps to create a pseudo-numpad. It appears to be a partial implementation of a design from ISO 9995.
I do have an explanation for the double-delete though: It looks like one of them was a replacement keycap. The left one is supposed to be the end key, according to this keyboard layout diagram from the manual
The keyboard layout is really wack though: UNIX ctrl placement, ESC to the right of F10 (with no F11 or F12), extra-long 1 key, and most bizarrely of all, two delete keys right next to each other.
