Mother X4 and DDI3 - Mods

[TotO]

Oh I thought he was talking about some sort of CPC mouse adapter.

You understood well. I was takling about a CPC mouse adapter.I have made some search, and it was the DK-Tronics clone done by Talrek. The original has 1 button, and the clone not fix that.It's only 2 wires to add on the design as there is a free input and output to the embedded IC.

Hmm, sorry , is not my fault. DDI 3 was designed as single interface for plug and play direct to 464.  Not as "add on"  for MX4 board what made only problems with stability. Long wires, poor power supply, weak connectors and many others problems. Btw, i made DDI3 with via thru connector too.

We don't spoke about the MX4 connector (it does the job using ribbon cables as well as for edge than centronics CPC, compared to the direct Edge connector causing bad contacts on many CPC because the weight of the expansion plugged on it, like the DDI-3 plugged on my 464 or 664 requiring a wedge to work), but the fact that peoples asked an edge path-trough when the DDI-2 was released and you don't by deflaut on DDI-3, that is not cool. But perfect if you allow that now. Better later than never!

Really!? What a  . With one button, most software suited to a mouse isn't usable. I even implemented the scrollwheel on my AMX adapter even though no software supports it yet, and that required adding 2 transistors and 2 resistors.

I must say I never had a CPC mouse or wanted to acquire one.
What is the killer software for a CPC mouse? Some graphical desktop? Painting?

iMPdraw v2 will use usb mouse but, albireo driver only!

OCP and PPP in example.

G-Paint uses the Atari-ST mouse adapter with two buttons. This is great, because the mouse is proportional.    Non proportional mice, oh well ...

When someone build new boards, it is the good occasion to fix the problem of the previous. (more when it is not the first try)
It is like the mouse adapter that orriginaly only support one button and nothing improved into a clone to suport two, etc.

By the was, about DDI-3 and MotherX4, if you do not use external PSU, yes what I will does is to remove the dioles and put a link only from the CPC pin 27 to power all the expansions. (supposing your CPC got enough power for that)

@toto did you ever make the requested / suggested changes? Jumper the diode / external PSU connection?
