Que grande !
pensé que pasaba al Incucai por su Z80

Nop, ahora como Mariano me la regaló es parte de la colección.
La C128 fue una máquina que siempre quiese (y no pude) tener.
Ahora tengo dos.

la c128 es la maquina que mas quiero de mi coleccion y la que mas disfruto de usar... tiene un teclado hermoso y comodo y es un fierro dificil de romper... lo unico que lamento es que no se pueda usar todo el teclado en modo 64, con eso seria perfecta! yo la tengo expandida a 64k de video y con "the servant" en e U36, y con eso soy feliz!.

Hola Diego me podes explicar que es The Servant?
Gracias

Bueno, encontre esto :

Extended Keyboard Use on the C-128 in C-64 Mode

Dave Kline 07/01/00 McGraw/Hill

Because extra registers are present in the C-64 mode on the C-128, you
can use the C-128 extended keyboard in C-64 mode. A routine using the three
extra keyscan lines at location $D02F follows. This routine wedges itself
into the IRQ interrupt routine by diverting the IRQ vector at $0314/$0315
to point to the code. Note that to scan a given column in the key matrix
(say, that connected to the K0 line), the output line is held low (logical
zero); matrix columns that are not being scanned should have their
respective output lines held high (logical one). (This is merely a
Commodore convention; another manufacturer's system might scan a keyboard
similarly but would reverse the process -- scanned key matrix column output
lines would be held high, while unscanned ones would be held low.)
This ML routine can be entered with the C-128's monitor but is executed
while in C-64 mode. The routine is called by SYS51968. To deactivate,
press RUN-STOP/RESTORE. (Note, other routines that use this memory area
while cause conflicts.)

Here's standard keyboard matrix of Commodore 64

(adjunto la imagen).

Ahi va la imagen de la matriz del teclado.

Perdón que no mandé el link y nada mas, pero ya me pasó de buscar cosas que "existian" en la web, y al hacer click el sitio no estaba, etc. Por temor a que pase lo mismo pegué el texto completo aca.

Esot es fantástico!! Se puede usar el teclado numerico de la 128 en modo 64?
Es una masa para poder tipear programas largos con muchos DATAs, como los Sprites, por ejemplo.

S!

PanchoAMD

Si. De todas maneras también podes tipear programas con muchos DATA en modo 128, grabarlos, y luego ejecutarlos en modo 64.

jaja BUENISIMO!... entonces corrijo... la c128 es PERFECTA!... y tiene tanto para explorarla, que uno nunca se cansa de descubrir cosas nuevas... una maravillosa máquina.
