 There's too many differences in key layout for this to be a practical option - you'd either have to redraw lots of key caps, or remove the offending 'system freeze' keys for it to be worthwhile, and since this is a shared keyboard with other systems, I can't really do that.
+Result? Not workable either; too many missing keys (e.g. a working backslash).

-Using the Japanese keyboard layout is even worse than the the UK layout as the shift keys do not work as expected (variation of caps effects and symbol-shift type effects). There are also still variations in characters produced (for example, the //Yen// or //bar|pipe// key doesn't work). Again, it would work to a certain extent with rewritten keycaps, but since the current keycaps are fine for the NEC PC-98, that's not an option. This option is a dead horse.

+Result? Waste of time. This one goes in the bin.

+As above, a reccomended keyboard from the [[https://www.msx.org/forum/msx-talk/hardware/finding-a-working-keyboard-for-lp-ps2-interface|MSX.org forum]], the recommendation being:
 > This one (Microsoft RT9443) works flawless. It even passes the infamous Gradius test (flying to the left top of the screen while still being able to shoot).
-There's even a video of the very keyboard in action:
+This keyboard is in US layout, as used by most others.

-This keyboard is in US layout, as used by most others. Still awaiting its arrival (June 25th, 2020).
+   * **Update: June 25th, 2020** - Found a cheap RT9443 on Ebay.com (shipping around ten times the price of the keyboard!).
+   * **Update: July 7th, 2020** - Keyboard arrived
+Result: //It doesn't work//. Same issues as the previous keyboards - no backslash/Yen key, missing bracket keys etc. This is getting ridiculous!!!

+**[Update January 2022]** - Tried this UK layout PS/2 keyboard which was new-in-box.

-**Update: July 7th, 2020** - keyboard arrived
+Result: similar to previous keyboards; no combination of keys can produce a backslash or Yen symbol. Other than that, it's a decent membrane PS/2 keyboard.
-//And it doesn't work//. Same issues as the previous keyboards - no backslash/Yen key, missing bracket keys etc. This is getting ridiculous!!!
