    Help with IC logic gate chips

    This will keep all my controller cable connections separate from each other - just won a cheap bid on ebay, 20 for $26 including postage. System will work as thus: An 8PDT switch will be used to select the console system (the 8PDT switch will carry the 8 data lines of a console system...

    Help with IC logic gate chips

    Yes ljcox, I did want to initially to get this working with logic chips as it would have been neat, however the simple solution is often the best one, and the simple solution was the manual method as there didn't appear to be an easy alternative. (*steve*) - each console controller has up to 9...

    Help with IC logic gate chips

    8 connections would be minimum but possible, 9 or 10 ideal as the 9th controller wire is ground which can be taken from the on/off switch. Better thinking about it to have the switch rated for 3+ amps and not the whole unit anyway. For various reasons, ground is being used for on/off per console...

    Help with IC logic gate chips

    My circuit works reliably as it is with each and every wire connection coming from a Zener diode. I know nothing about what diode's characteristic is vs any other, I had a few samples of diodes and experimented; the Zener ones worked whereas others seemed to block entirely. Whatever the reason...

    As you asked to see the video, here's the link - i'm still none the wiser about the IC chips needed for this application however resolved with Zener diodes.

    Help with IC logic gate chips

    No issues with loads of diodes, or their wiring; my soldering skills are pretty good (I have steady hands so can do pretty intricate soldering work) and i'm literally soldering thousands of wires in this project anyway. Certainly, i'll upload the video when done for the Intellivision d-pad...

    Help with IC logic gate chips

    I am grateful for the help you guys have offered and the welcome. What I don't want to do is be inaccurate in the information i'll ask if I can. I might have resolved my first initial query with a manual method, will know in the next couple of days; in regards the application with the...

    lol "Geek" is a compliment in this context ljcox, "nerd" isn't; to quote Wikipedia: (*steve*) - to use the anachronism and adjust your lol comment if I may - the problem is akin to bacteria exercising his entire knowledge of the Italian language by saying hello to a person in Italian, and...

    Help with IC logic gate chips

    This is like anything else, we are all geeks on some subjects and know nothing about others; i'm geeky on what I do and you guys here are geeky on electronics, which is why I came for help as my electronics knowledge is very poor. What I was hoping for was "ah, you need this and that and this is...

    Help with IC logic gate chips

    Guy on the Intellivision forum pointed me to this: http://web.archive.org/web/20060317145051/users.erols.com/tiltonj/games/tech/intvsticky.html According to the diagram, doesn't use the 5v and resistor (for the directional control, ie d-pad), just the button contacts, which is what I...

    Help with IC logic gate chips

    20 manual switches, one per console system, to turn system on or off. 9 inputs per console (the controller cable with up to 9 wires inside) = 180 inputs (20 x 9) ie 9 chips each with one output and 20 inputs; each chip will output one signal from the choice of 20; depending on which console...

    Help with IC logic gate chips

    My worklogs are comprehensive as I like to share my modding knowledge to all, i'm a believer in sharing knowledge rather than keeping it to myself (which is a reason why my forum is quite popular); however yes, this means lots of posts on my threads. I'm resolving the issues with the original...

    Help with IC logic gate chips

    Thanks for the information, useful. Problem I have is this - I have two applications and neither seem to be suitable - if i'm wrong i'd love to know it and be put right! 1) the application I referred to in this thread relies on only two inputs - ground and the button press. I can't pass...

    Help with IC logic gate chips

    Ok, think i've found a mechanical way; in my worklog thread on my forum - 1/4 of it works so far... http://moddedbybacteria.freeforums.org/alpha-omega-project-cart-and-cd-based-systems-in-one-t250-300.html#p11474 I'll look into the board you refer to later on, I think i'll still need it maybe...

    Help with IC logic gate chips

    PICAXE looks interesting, although i'm a bit loathe to buy lots of stuff without knowing exactly what I need and how to use it. I've wasted money to date on good ideas that I haven't been able to fulfil. I haven't programmed since about 1984, I used to do QBasic and a little Assembly Language...
