I am guilty of not viewing these videos by CabryDYI (french inside), but reading the title, they should interest you if you need to repare or service an Amstrad GX4000. Happy viewing.



New batch of the V9990 CPC Powergraph using a MX4 port

-

A new batch of the V990 CPC Powergraph card is available (card by Tecnobytes), 30 will be available with already 16 taken. This card is connected on a MX4 slot to be used on an Amstrad CPC.

This is not the V9990 Powergraph Light Rev 2 with built-in adapter by Tecnobytes, which is a MSX cartridge for MSX or Amstrad CPC which you can connect with the Amsdap (MX4 with a cartridge slot), see Prodatron's video in 2018.

Several programs are being written for SymbOS using this graphic card, including FlappyBird.

Beware this graphic card needs an analog 15 kHz signals through discrete RGB connectors (VGA, DVI-A, and/or SCART), check the 15khz wiki.

Reading a 15KHz sound sample while formatting a floppy on Amstrad CPC by Roudoudou

-

Roudoudou has written a ROM to format Amstrad CPC floppy disks which can play a 15KHz sound sample while the formatting.

Also, if you are curious, there is video shohis demo CRTC3 with the debug mode of the CPCEC emulator.

And the bonus video with Roudoudou himself explaining his return on Amstrad CPC is worth its weight in gold, french inside of course but translated subtitles should be interesting for any computer user.



Nova v1.2 by PulkoMandy, a NVRAM and RTC expansion card for Amstrad CPC

-

Pulkomandy has made in February 2021 a new expansion card for Amstrad CPC(+) : Nova. This card is now at version 1.2 and let you use non volatile RAM (32 Kb) which is kept even when the Amstrad CPC is off, and a real time clock. The NVRAM can be used by Unidos (about which I really must write).




Plus2CPC, an Amstrad CPC Plus cartridge slot for the vanilla CPC by Abalore

-

Abalore (look for his Youtube channel) is not at his first Amstrad production (see below), and today he is at his best as he made a simple electronic interface adding a cartridge slot for the plain Amstrad CPC (464, 664 and 6128) which can only be used normally on an CPC+ or the GX4000 console.

Beware, it doesnt add magically the CPC+ features. But it's the key for games with a monstruous size up to 4 Mb with a simple memory banking.

And you can also use it on an CPC+, the internal cartridge with Burning Rubber or basic is still usable, the Plus2CPC will let you load games or another operating system.

A file to be used with a 3D printer is available on his web site (see above). He can make a version with edge or centronics connector, or MX4, v3 without reset button or v4 with reset button.



Willy by PulkoMandy, an Amstrad CPC(+) adaptator for using parallel PC sound cards

-

On Serdashop you can found audio and video cards to be used mostly on PC. For example there are two cards which are connected to the parallel port of a PC, especially those which can't use ISA/PCI sound cards such as old portables :

Pulkomandy has created a card for Amstrad CPC(+) : Willy which lets you use an OPL3LPT or S2P on it. He wrote two programs to use the OPL3LPT which you can found on his page :

Check the CPCWiki thread for more informations and short videos of the Willy + OPL3LPT being used.

By the way, there are other ways to use MIDI on an Amstrad CPC, but it will be for another day (hint, use serial, usifac, LambdaSpeak...).




Powergraph Light Rev 2 with built-in adapter for Amstrad CPC to connect with an Amsdap

-

I am late as today is the last day to order a V9990 Powergraph Light Rev 2 with built-in adapter by Tecnobytes. It's a MSX cartridge for MSX or Amstrad CPC which you can connect with the Amsdap (a MX4 card with a MSX cartridge slot), see Prodatron's video in 2018.



An Amstrad PPC 512 operated by Noël Llopis (repairing, upgrading, screen changing) in 5 videos

-

Noel Llopis did start 4 months ago a serie of videos about an Amstrad PPC 512 whose screen has suffered just a little bit... The videos are very interesting and my resume below cant show how interesting these videos are. Take the time to see them from start to end as I did.

  • first video in which he will open the beast and trying to replace the broken screen with another screen from a PPC donor. Then he will use the CGA2SCART PRO made by Retro Erik. The CGA2SCART Pro permits to replace a CGA/EGA screen with a television using a SCART cable (RGB signal). Then he is running two of his msdos programs he wrote mayn years ago : Return of Frankenstein (3D isometric game) and Bouncing Ball
  • second video where the screen will be repaired after many tests, a real work of a police investigagor but in electronics
  • third video, it's time for upgrading (adding and testing a Gotek, adding and testing more RAM to get 640 Kb) and some reparations (the handle and the protection hatch at the back) to finish by dumping the spanish ROM of the PPC which wasnt available on internet, to be used with an emulator (MAME or PCEM)
  • fourth video, the screen has been repaired but it's not perfect. So the original screen will be changed, two solutions being tested : MCE2VGA (which I use with my own PPC 640) and the GBS 8200
  • fifth video, it's the part two of the fourth video where he is using a third solution to replace the original screen with a Raspberry Pi zero and the HAT RGB to HDMI which allows the use the HDMI output of the Pi (bare metal emulation, no raspbian OS used)


Amstrad PPC 640 replica running RetroPie by Bill Kar

-

You have a dead Amstrad PPC and you heart is too heave to throw it inside the bin ? Then why dont you use a magic wand to transform it into a retro console or better to use PCEM to emulate an Amstrad PPC ? It's what Bill Kar did with its PPC 640.
