LS3 received, and posted... here a picture of the hypno lights... Two are off, I assume they are spare for a firmware update?

Amstrad CPC hardware / Re: USB power supply for CPC/PLUS

Burning rails off the PCB can happen also when touching the joystick port and the screen (newly switched on) at the same time. 5 A nevertheless is enough for the whole system :)

Amstrad CPC hardware / Re: USB power supply for CPC/PLUS
« Last post by logiker on Today at 20:27 »
Some years ago I used a PSU that I ordered from the greek ebay user ikonsgr74. I think it had 3A and it worked very well. I also got a TV cable (Scart) from him.
The only thing I am not sure about is, if and/or how I connected a drive. I think I just used a HxC drive.

There is a legend about a tiny screen burning the middle of the monitor (i don't believe it)Some Chany's demos use 65 NOPS lines or more which made the monitor doing some noise (some people are scared of this)

What is your suggestions then??


Are there any safe PSU apart from the monitor??

Indeed, Plus support can be added on, but a good Plus upgrade would take a bit of time - hardware sprites and hardware scrolling being the obvious additions.
But developer should do what they want to do and what motivates them.

I see it more as, if you want to write a game for the 464, go for it. If you want to write a game for the GX4000, go for it. If you want to write a game for a CPC which requires a PlayCity and 4MB of RAM, go for it. If you're the one writing the game, you get to choose what hardware platform you are interested in targeting.


Anyone who wants to do another port of NZS to the 464 (or whatever) can go right ahead.
Definately, the Dev should choose whatever target platform interests them most... It's all about seeing it through to the end, and aiming for what you see as your 'goal'

And of course CPC+ colors can always be added once the game is complete without too much work if there is demand for it.

maybe a cartridge release should include the extra-ram needed in that case.

That's fine, but more people would buy a physical copy if made for both systems or just the CPC.

PD Graphics 7.

1. Shapes/Spiral (The Final Chapter)


Yes so the values entered won't change the output Spiral produces. It has something to do with the RUN"SPIRAL not clearing the DEG mode, which Shapes sets up. From what I recall in your earlier video it uses COS and SIN to store the values into arrays called co() and si() while in DEG more, though SPIRAL just uses COS and SIN to get it's values. In the Manual the RAD command talks about NEW, CLEAR, LOAD & RUN restoring back to the default mode (RAD), it seems to be true for NEW, CLEAR and RUN, but not LOAD, I tested and this doesn't seem to be true, though if I had LOAD"SPIRAL followed by RUN, the RUN would return BASIC to RAD mode.

I know this one so well, which was published in AA53 Type-Ins (Feb. 1990). It's been modified to add Lines 21 and 22 for the Introduction to it.

3. Channel4 (Also loads a binary file)


A couple of files are loaded, I was almost expecting it to be a BASIC 1.1 Graphic using MOVE, DRAW, FILL to create the iconic Logo, instead it's a Squeezed (Compressed) Screen followed by some Theme Music which almost sounds like the speaker wants to Escape itself.  :D


I found this little video clip which plays a whole range of variations on the theme which I thought was amusing  :D

I'm unsure, but this Left & Right Scrolling Demo seems familiar, but I'm unsure what it's from, I may have picked it up on CPC-Power while looking at Scrolling Examples.
