Would definitely need an LA if I started with PLDs then.
Will keep that one on the back burner for now but got the programmers etc already.
exxos IDE interface (untested)
Re: exxos IDE interface (untested)
If it ain't broke, test it to Destruction.
Re: exxos IDE interface (untested)
ATF15xx series needs its own special programmer.
The good thing about them is they 5v, and the software is suioer simple. Its almost like notepad with a compiler none of this 30gb bloatware rubbish. I like the altera software, but takes more getting used to. I've only used itnoince and that was like a year ago. But at least its not to bad to get going with. Really just want to stick to simple chips until I have need to go bigger. Hard to keep everything in my head all at once

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~
People should find solutions to problems, not find problems with solutions.

Re: exxos IDE interface (untested)
Yeah, could route it all though a larger PLD as well I guess, or like you say, bus drivers.

Re: exxos IDE interface (untested)
A few steps forward over the last few days. Working with Exxos have reverted to using some GALs to reduce the many logic chips.
Cartridge Port Breakout board is read to work with breadboard. This helps to get most of the data lines and address lines out.

Re: exxos IDE interface (untested)
A few more steps forward.
Still a bit more to do
Still a bit more to do
- Tying several pins down to ground
- Adding in all the extra lines back to the ST
- Checking everything out
Re: exxos IDE interface (untested)
That looks really cool, good luck, hope it works etc
If it ain't broke, test it to Destruction.
Re: exxos IDE interface (untested)
Wow indeed! Who would have thought such a "simple" circuit would end up like that, I'm starting to appreciate PLD's a whole lot more all of a sudden Though I also really hate PLD's

Re: exxos IDE interface (untested)
Ever so slowly getting there. Christmas has definitely got in the way.
Have ran out of test hooks to help with the setup and also need to finish off a few grounding of unused pins on some of the chips.
Hoping to power up tomorrow after crafting a few more wires to add to the mess.

Also appreciating that this, although simple, is one wiring nightmare. Roll-on PLD version if this one works.
Re: exxos IDE interface (untested)
Same here. I learned eating 6 satsumas gives me stomach ache!
Now that's a proper prototype! Yeah, it will all come together in the end and be the worlds first stable IDE solution
