Quote from: Ygdrazil on 14:13, 01 October 10Hmmm. I would prefere transparent then
Quote from: arnoldemu on 14:23, 01 October 10me too.MacDeath comes in, teases us with "the cpc+ cart is similar to Atari carts", and then doesn't come back to give more details.Damn.

Quote from: Bryce on 15:09, 01 October 10Here's what the transparent ones could look like. If decent hard plastic is used, then it should stay looking good for years (assuming you don't store it in a box full of sand / blades / assorted scratchy things).These are made for c64, but whatever company made them, could make the same for CPC for a reasonable price if the quantities are high enough. These are sold for about €4.50 after the reseller has made a profit, so the production price can't be all that bad.Bryce.Edit: you could even add some LEDs and make it glow

Quote from: Nilquader on 10:43, 15 April 11There's no need to wait I've just put the Verilog code used to simulate the ACID on the Wiki. It was written by Octoate and me at the Xzentrix Party 2010. Schematics for the cartridge will follow as soon as we finished it. And there are more news: It's possible to start the CPC+/GX4000 completely without ACID by exploiting a timing bug in the CPC+/GX4000 ASIC. It needs just 5 standard components. Photo and schematics are on the wiki. Detailed explanation will follow as soon as i find time for that. Edit: Why does the CPC+ run without ACID?As soon as the CPC+ ASIC detects a wrong signal on the SIN line it pulls the CCLR line down (as you can see here: http://www.cpcwiki.eu/index.php/File:ACID_Init_by_Grim.png) The 74AC112N is a RS Flipflop which switches the polarity of SIN as soon as it detects the Pulse on CCLR. (You need the 74AC series. Everything else isn't fast enough and won't work!) The ACID now gets the correct SIN level and sets CCLR high again. And everything runs fine until the ASIC detects the next "wrong" level of the SIN signal. So the CPC+ tells you everything you need to fool him
Quote from: redbox on 11:34, 15 April 11@Nilquader - you say you can start a Plus without the ACID, but does it keep on running? What happens when the ASIC detects the wrong SIN level again?
QuoteEDIT: Nilquader, please can we have a more closer view of the 74AC112N version?The picture doesn't do it enough justice.
