I want to start by saying thank you for this converter. I have been having issues with the PS2 → USB converters, Especially with a docking station. And a Unicomp i got also has an similar issue with docking station and suspend/resume. (this is not the mini so it is not supported for the upgrade unfortunately)
I did run into a few issues.
the only information i found (including the gitHub pages) for how to connect the 16p header in the 20pin PCB was the image from Bryson_Osborne. (i think i see references to a website that is now dead.)
the LEDs are illuminating the wrong order.
my keyboard has the order: Num | Caps | Scroll
the MStar Lights the LEDs in the order: Caps | Scroll | Num
This is on a 1989 1391401, that came with a 386 SX PS2.
Hey, super glad my picture was helpful!
I would imagine that, for point 2, you can likely fix that in the firmware. Mine don’t light up at all, but if the wrong one is coming on, that should be (relatively) easy to solve with software.
As an example, this is from the file located at m-star/QMK/m_star_classic/m_star_classic.c
bool led_update_kb(led_t led_state) {
bool res = led_update_user(led_state);
if(res) {
writePin(led_pins[0], !led_state.num_lock);
writePin(led_pins[1], !led_state.caps_lock);
writePin(led_pins[2], !led_state.scroll_lock);
}
return res;
}
You should be able to change the value inside the brackets next to led_pins to match what you need.
You can always flash this to one of the other presets or create your own. Instead of changing the kepmap yourself though, the github page has presets that may be helpful to you.
The default flashed on the controller is the “wendell” profile.
Well, got it to work eventually, apparently the latest version of QMK renamed the lock keys (scroll lock, cap lock and num lock), and also removed the terminal (so no TERM_ON, TERM_OFF) (and some other things)
The version of the Wendell profile on the m-star site worked fine without any key-lock LED remapping (even though i first swapped it programed it and then undid it again).
I also got my old model M 122key working (mostly) i will need to do a bolt mod on it for all of the keys to work though. (i was saving it planning on doing some sort of conversion with it ages ago and never did)
My local recycler has a Model M 1391401 Keyboard (October 1992) that I could probably get for $50. As someone who knows nothing about these keyboards, is this something worth picking up?
Having followed the How-To Guide from @Level1_Amber as well as the QMK Tutorial, I attempted to flash Wendell’s layout onto my new M-Star controller in my new Mini M and ran into significant trouble, though I suspect that it is something quite simple that I am missing - like the wrong files a missing command argument, something like that.
The screenshot below shows the errors I get when I attempt the QMK Flash command (attempting the “minim” keymap first). Also, it wasn’t exactly clear from Eric Raymond’s gitlab where to find the correct source files because some of his documentation references /QMK/m_star-mini but there is no such directory in the repo, but there is an m_star_classic, which seems incorrect or confusing.
@Wendell (or anyone) would you be so kind as to point me in the right direction here? Thank you!
You saw this post too, right? You’ll get some errors when flashing.
This is a copy of the output you should get:
