There won't be a magic place I can think of selling specifically for these monitors. Digikey or Mouser will have a wide variety of parts which should meet the dimensions and voltage ranges you need

I would personally invest in an ESR meter and check them before replacing. The various monitors I have here show all my caps are within EGR range. 

You are lucky you still have correct power to the primary transformer. Both of my units have had the voltage regulator, diodes, fuses and 5.6 ohm resistor taken out by the flyback

It's probably easier to update WEC with mode 0 on the CPC that it will be trying to get this working on a normal CPC.

Thank you for all these very useful details. 

In fact, it was me who misunderstood, sorry.  
I hadn't thought that the game was launched on an Amstrad Plus with the Plus features disabled (I had thought that the CPR had been modified to run on CPC old, with the Plus functions disabled...  )

Amstrad CPC hardware / Re: Serial port

Last post by Rabs - Yesterday at 19:12

Hello

Is there a board that implements a serial port for amstrad?  Or any schematic?

Thanks

I think there are quite a few.

I have one CTC DART.

You have the Usifac, if what you mean is a RS232, well, the Usifac has it too

How did you deactivate the CPC Plus functions?

How is it carried out? (C4CPC, M4 Board with CPR injection, other)

Thanks ! 😉

-The cart84, that is the first activated on &C000, I put it in &C000 configuration &C3.
-The secuence for activate the plus hardware, put nop nop in the out (c),c bucle.
-Deactivate (nop nop on the out (c),c):

  -ld bc,#7f84 (for not activate the upper rom on classic)
  -ld bc,#7fb8 (for not activate the asic pagination)
  -ld bc,#7fb0  (they don't use #7fa0) for not deactivation de asic pagination
  -ld bc,#df84 (on the plus this activate cart84)

-Preventing the program to erase with ldir the range on &C000

-The writings to the Asic registers on the range &6000-&6xxx doesn't matter on the classic.

-the nops on the outs were made with search of the ld bc's with F3 on winape

Now i'm trying to de the same with Pang, it seems that they activate the IM2 ints, and something is erasing the table of ints, crashing on classic. I have to look what is happening.

Beside this, i don't think that it has any use on a CPC classic, Pang for example, the balls are hardware sprites, how difficult can be to do it with software on classic? any chance to run Pang on a classic changing the hardware routine for software ones?

Okay, here is what the issue is:

With the X-Module, the CPC can work with 2 sided drives. That means that the side pin has relevance and is getting used (where with AMSDOS is always high).

However this line looks jittery on one of the controllers I have.

I need to look at it with an oscilloscope, but I just think, the line is floating instead if low. High is not a problem, but low will not work.

So all mysteries clarified so far and GOTEK is working just fine.
