Hi
I am looking for someone who can do me a favour.
I am in the search of a single board pc, that has tv out(rca), an IDE interface, a couple of ds1265ab-100's (for NV ram) ,a at or ps/2 keaboard and a serial port or two and if possible one paralel port and a few spare I/O s.

It must hopefully be cheap , using either a zilog80 or 65816 cpu(its the only two that I can get (I live in South Africa), and its much to expencive for me to import things like that,the zaR/$ exchange rate is is very bad, its like R7 for one dolar.

Just as a idea, why not use one processor as a controller for the IDE, another for the nvram,tv out and keaboard and another for the serial nd parralel port, and then like em all together, or something like that.

it must be as low budget as possible.

I cannot do tjis myself, for it will take me years to just learn how to do it, since I am still going to school.

thanx

Hi,

You're really going to need to explore your options / needs / wants here.

Personally, I'd say go around to the various links in the projects section - most of them there have at least some of what you want, if not most. I'd say to take a look at Chris Ward's stuff, Lee's stuff, Adam's great 6502 stuff, and JDEBoy's (Joachim) information (JDEBoy's is through his posting to this board - post: http://www.6502.org/forum/viewtopic.php?t=218 ), as well as information from the Speccybob2 design (the website seems to be down atm, but this guy has a wonderful little system that was based on the sinclair spectrum) All of these areas have tremendous information and are wonderful starting points. And if you have a question on how to make something work right or ideas on something, many here like Lee, JDEBoy, Garth, KC5TJA, and others will post and can help out tremendously! The people here are really great people.

Now for the not so great news.... Although most people here are more then happy to help out with ideas, concepts, "am I doing this right", etc. - I don't think most if not all here would be able to custom design a computer like you are talking about without something to compensate them for their time / parts / equipment, etc. - a custom designed system that isn't homebrewed for the love of it would be very expensive - especially if the market is 1 system. That's why most here experiment and work on their own designs and such - when doing it for ones self, it's a labor of love in the hobby, when doing it for someone else, most would probably need incentive to invest their time in something for someone else.

Now, this isn't to say you can't make an awesome system, or that people wouldn't be willing to help - I just think you're probably gonna have to come up with a lot of the design on your own tho. Plus, the huge benefit of doing it yourself - if something goes wrong - you can fix it. if something doesn't operate the way *you* want it to - you can change it to suit your needs and/or wants.

Take a look at some of the projects on the net - many have code to make them operate as well - almost all have schematics, which would make it possible for you to make one.

Just my humble opinion. Good luck in your design, and if you decide to piece together a variety of ideas from different systems, please bring your progress here or ideas/questions/suggestions, I'm sure help could be provided (I'm not necessarily saying I could help, I am not nearly as proficient or qualified as many of the other poster's here - I'd do what I can, but I would definitly defer to someone with much more knowledge then I to prevent causing more confusion

I forgot to mention one of the other sites I love that has a great deal of info - Daryl's 65c02 pages - it also has a tremendous amount of information, including output to video. I must appologize for not including this one - it is definitly worth going to.

After a long search, I found som achematics, but I dont know how to connect the up.
I will try and post them somewhere this week

thanx

here is the board
that I was talking about.

the schematics are in eagle format

That link you gave doesn't seem to work, can you put a link to the file on your homepage?

Lee.
