Superfo 128K [Gerber disponible]

[cdvazquez]

Para los más detallistas... los archivos que están colgados son de la versión 1.0B.

La placa que compré es la 1.0. Me comenta Superfo que sólo hay un pequeño cambio en U4 que puede solucionar algún pequeño problema que podría ocurrir en algún juego y demo... pero que en las 1.0 que él ha montado tampoco lo ha habido en las pruebas que ha hecho.

Sobre la anterior, 1.0, que compré en ebay, me ha pasado esta información:

Harlequin 128K v1.0

Saludos.

For AY address decoder, it is my fault, you can fix it by disconnect A12 from pin 6 of U4, then connect pin 6 of U4 to VCC. And disconnect pin 9 of U51C from pin 9 of U4, then connect it to pin 7 of U4. (issue 1B has this fix already).

Many thanks superfo, but the links don´t work, can do you fix it?

Hi Superfo!

Just got one of your new Issue 2 boards, I'm now gathering the components and some quertions arised:

- Voltage regulator: I've not found any of the voltage regulators you suggest, I suppose any (any good one) 5V regulator will do. The pinout look like it is IN,GND,OUT Is this ok? (it looks like it is, just to be sure)

- Circuit made with U39, R59, J13, D6, D7 & R58 ... Is this some kind of Joystick port? How is it used?

Buenass.
Yo tengo montado un harlequin 128k de zdp, cuando se le puso la CF, adpatador ps/2, etc. He estado retirado de los foros, pero creo recordar que en algún momento Antonio me pasó el esquemático y/o la pcb para acabar de rutearla. Pero como las versiones han ido cambiando no se cuál es la última y si sería interesante hacerla con todos los extras. No se. Saludos.

Hi,

- Regultaor, yes you can use any 5V regulator, IN is inside pcb(left), GND is middle and OUT is outside pcb (right)
- U39, R59, J13, D6, D7 is Kempston Joystick interface, yiu have to wire from DB9 (male) to J13, see schematic for detial.

Superfo ha dado el visto bueno para hacer uso de sus gerbers. ¿Habría interesados?
Obviamente yo el primero.
