Last post by overange - Today at 17:05

Ok guys, it's nice to see Triaxos working so well, but it also party time for a new game. As requested by @overange , here is a new conversion thanks to the work of @Urusergi and @dragon  with my humble involvement:

RED HEAT from Ocean

Controls:
J1B1  = Fire
J1UP  = Head butt / fire gun
J1DOWN = Duck / Pick up
Pause button = Pause game (any button to resume)

Modifications for the GX4000 version:
    - Original title screen but also a new one in mode 0 based on the C64 version,
    - Wait for fire on title screen,
    - Patched keys,
    - Joystick as default controls,
    - Plus incompatibility fixed,
    - Modified disk access routine,
    - Pokes: Unlimited lives and health

Many thanks to @dragon for the modification of the disk access routine to make the game work converted in CPR. You're a real master, dude

Fantastic to all those involved

Thanks again everyone.

Looks like a false alarm. Opened up to check capacitors, but no signs of failure.

Sprayed contact cleaner into the volume knob, let it dry and tested again. Sound is fine now! 

Can play Brick Rick again!

Only 50 people reading this forum?  Come on!

There are currently 3,725 registered users on the forum, but it would be an interesting exercise for @Gryzor to analyse how many of them are currently active (i.e. have logged in within a certain period of time).

In the end, I just converted to running on USBC PD.
12V feeding into the 12v line and a buck converter to derive 5v and feed that into the 5V line - all at the analogue board connector.

3D printed a new peice to cover where the mains cable used to come out.
Available on thingiverse for anyone who needs in future
(https://www.thingiverse.com/thing:6595466)

No 24V supply but I dont have a printer.
Could be generated from a boost converter but I'd imagine the wattage is quite high.

Amstrad CPC hardware / Amstrad PCW 8256 - Gotek Drive...

Last post by troupe86 - Today at 11:20

Hello all!

I've recently acquired a lovely PCW 8256 computer and I was wondering if there is a readily available Gotek drive solution for it?

My searching online hasn't shown any available for sale, despite some articles showing the installation process.

Thanks!

Thanks!

Technical support - Hardware related / Amstrad GX4000 - Video Problem...

Last post by josepprada - Today at 09:57

Hello guys,

I'm in the process of restoring, or bring back to live a GX4000, when I bought her, she has power (green light) but nothing on the screen. And the controllers with the wire's completely cut.

I was aware of the double input voltage, so I never put a power supply on the 5v in (but I can assure that someone did it before).

First time I plugged in a 9v 1A PS in the 11v in, green light appears, but some smell of burn appears in a few seconds, so I powered down immediately, and began reading in depth the forum to find the issue.

Reading about burned smell, I saw that the if the RAM was bad, it heats a lot, so I put my finger on them and it was hot as hell! So I decided to replace it.

But nothing happens, no video, no audio.

I began doing measures in the Power Board, and I find that the Voltage regulator IC181 7805 had 9v in both pins (in and out). I replace it, but same happens, and find a video in Youtube about change the Diode D183. I replace it, and now the IC181 output pins is 5V!

So, I put a multigame cartdrige (like C4CPC )  that I bought power on, but no video at all. So reading the forum I find several references to no video, but audio in the MiniJack. So I connected headphones in the jack and EUREKA! There is sound!!! I connected a repaired controller and can hear changes in the menus or in the game, so the GX4000 process is working!!

Now let's go to my problem now, I have no video on RF or on SCART. On RF sometimes I see snowed images of the games if I move the RF antenna cable. So I have a problem on the video part.

My first test was to measure the other voltage regulator IC17 that I understand that powers the video section, and the measures are weird. I suppose to have 9v in and 5v out, but I get 5v in, 3v out. I did not replace the IC17 because if it was a problem with it, I'll see 9v in, so maybe the problem is somewhere else.

Can you help me find we're the problem is? What test can I do?

I only have a multimeter to do the readings, I do not have an oscilloscope or advance tools.

Thank you in advance!!
