Tilde and backslash don't work on PCXT core?

Can anybody help me figure out why the tilde key (~) and backslash (\) don't work on the PCXT core?
The backslash key sends a backspace instead and the tilde key doesn't send anything.
The keyboard is a standard US layout and works fine in the ao486 core (and everything else)

Currently, a numeric keypad is required to type tildes and backslashes in Tandy mode (+Tandy BIOS).
This is because the keyboard layout of the Tandy is slightly different, which makes keycode conversion a bit more complicated.

Sorry, I should have mentioned I'm using Tandy 1000 mode.
Do you know if there are any plans to implement these keys?
I'm using Tandy mode for the EGA graphics (and Tandy sound chip for early Sierra games).

One point.
Tandy mode does not have
EGA graphics, but
Tandy graphics, and so far only
320x200x16 mode is implemented.

OK - Thanks for the information. Hopefully the keycode can be mapped (?) because it's a difficult to type Alt-126 and ALT-92
Does the XT BIOS support Tandy graphics or only the Tandy BIOS?
Also, the audio (both Tandy sound and Adlib) are extremely choppy?

Only
Tandy BIOS.
Well, maybe it's because of that player you put, which consumes a lot of
CPU resources, but it is strange, have you tried
14.318Mhz?

Hmmm, I've also tried KQ1 (AGI) and it has the same result. I'm also running at 14.318 MHz. I've tried lowering the CPU speed (and HDD speed) both it has the same result.

Does the core support a Num Lock key? (if we want to switch \ to 7 etc)

I'm testing it and it's working fine, I'm with the
prerelease version which I will release soon.

This was very helpful. I was using a wireless keyboard that doesn't have the numpad. Numpad 7 is backslash \, and Numpad 8 is Tilde ~. Is there a map that shows how the Tandy bios is reading the whole keyboard (at least for a 101+ keyboard, my wired USB keyboard is 103 keys)?

Sorry. I don't have any documents that I can give you right now. I have not produced any documentation on this matter.

I have created only the numeric keypad portion.
