Este kit de conversión le permite reemplazar la placa controladora interna original de su IBM Model M con una placa USB moderna. Esto tiene como objetivo igualar el tamaño del controlador original y se conecta a la matriz del teclado original, pero deja expuesto un puerto USB a través del conector SDL original.
Gracias a QMK, el teclado es totalmente programable. Se envía con un gestor de arranque estilo DFU, que se puede programar a través de USB.
Características
- Actualización no destructiva: simplemente cambie las placas
- USB nativo (con conector tipo B), no requiere adaptador
- No requiere controlador original
- Procesador STM32 ARM a 72 MHz con flash de 64 kb
- Claves reasignables (usando el configurador QMK)
- Utiliza firmware QMK de código abierto
- Menor potencia (50 mA típico)
- Conectores originales "TE Connectivity Trio-mate", como los utilizados en el Modelo M original
- Fuente de firmware del modelo H QMK
Incluye
1 x placa controladora USB modelo H (programada y lista)
1 x cubierta de caja USB de repuesto impresa en 3D
1 pegatina troquelada KEEBD.
Compatibilidad
El modelo H viene en dos variantes para combinar con diferentes conectores internos.
Este controlador de actualización admite ambas variantes.

The Model H controller is great way to resurrect IBM Model M keyboards. Even though the three keyboard I have are “very early - 1986” models, the controllers worked perfectly. IBM used molex connectors for the LED’s for early models, Easily fixed with a 3D Printed adapter and a bit of creative copper work. IBM’s pinouts vary a bit, but are easily fixed via QMK. Since I was making an adapter anyway, I just switched the pins in one end of the molex-based bundle of wires.
There is lots of online support for the Model H, so it was easy to figure out.
Easy installation and worked perfectly
Arrived in UK within two weeks of order, well packed. As shipped it assumes an ANSI layout so needs reconfiguration with QMK or VIAL, pretty straightforward with the binary VIAL firmware at https://github.com/jberclaz/modelh/releases flashed to the board using dfu-util followed by reconfiguration in VIAL to add mappings for the missing ISO keys (add these via the "Layout" tab in VIAL). If you have the separate LED cable then this enters, maybe counter-intuitively, from the "top" of the board. Very happy and now working smoothly across multiple machines via a KVM switch, which the original IBM board + adaptor never handled properly.
This is a super upgrade for a great line of keyboards. I replaced the PCB in the M Keyboard with Model H USB interface. It just worked and so much better than the PS2 to USB inline adapters. If you own an M keyboard, do this today!
In total i ordered 3 Model H's with KeeBD, all working as it was intended to be.
Shipping was very fast, coming from Australia it takes some time to come to Europe though.
All good, will definitely order again as i have this Model M restoring fetish :-)
