Any luck on the web? I am also interesting in a more detailed description of the expansion port signals for external ROM modules. Posted By JamesC on 2003-12-28  Re: C16 external memory expansion Aha, Lando, I knew those pics you sent me would someday come in handy! I don't have a circuit diagram but when Lando obtained a 16k cartridge memory expansion about a year ago, he sent me photos of the cart both front and back. The resolution is great enough that a circuit diagram could be made. Please email me privately if you want the photos, til I get a chance to put them on the website. Alternatively, the webmaster of www.6502.org sent me a brief article on how he expanded his C16 to 64k internally, that is already up on www.cbm264.com.

I have one external expansion too (Hungarian made) but it's melted into plastic I'm afraid :-/ Posted By Bionic on 2003-12-30  Re: C16 external memory expansion Thanks! Wow, this layout is confusing.. will take some time to figure out the circuit Back to top Reply to this topic Copyright © Plus/4 World Team, 2001-2025. Support Plus/4 World on Patreon
