14mb board (various docs, pinout, ctr14 gerber files)

[djbase]

Great. If anyone is using this board with any speedups (Skunk, Nemesis, CT,...) please report if it still works or gives some errors.

djbase,

I have installed the board in my falcon, its a stock falcon with a 4gb drive in it, connected with the rf to the tv.
I installed some edo ram in it i got from my work, but only the double sided memory seems te work.
When i install the memory and turn on the falcon, it appears as if the screen is getting up to the required framerate, then i have to turn it off and on again and after the same flickering it shows me the atari logo.

As if the memory needs to warm up or something.

50% of the times the falcon gives me 4 bombs (illegal instruction) after a few minutes of operation (there is no difference if im doing something or not, or using the connected hd.)

I am thinking i might have used the wrong kind of ram, do you have advice which kind of 72 pins ram i need to use?

Regards,

Justin

ps.

The original 4mb atari ram works fine.

[djbase]

Don't use EDO Ram. You will need FPM Ram. The one I have has Micron chips MT4C4M4E8DJ with 60ns.

[Faler]

Is there a difference in using double sided or single sided ram?

[djbase]

It should be single sided with 8 chips.

Just drop a PM with your address and you will get a total return. PayPal available.

[djbase]

I picture would be nice as all Falcons I had didn't have a problem here.

Sorry for the crap photos.

I am not 100% sure but I think Simbo was referring to a problem I had with all three of the Falcons I've got access to. They all have 90' a step in the shielding which goes above where the SIMM sits.



Here you can see that the shielding cannot be put back on after fitting the SIMM adapter. There is not enough room without the SIMM let alone with it.





I was a little bit disappointed when it did not just fit back together perfectly. However a few minutes with a pair of TIN SNIPS should work. I'll have to do the metal box over the floppy drive too which also does not fit

My falc came with the square metal shielding.
It came off since mid 90s when I got my 14MB memory upgrade.
Not much issues with interference what so ever, even on my monitor (back then).
On the TV, there seems to be some minor diagonal interferences.

[alexh]

What did you do with the internal speaker though? Ditch it?

[wongck]

What did you do with the internal speaker though? Ditch it?

Nah, it's there.
Sits between the HDD and FDD cables.
Sometimes I wonder if the magnetic part of the speaker is killing my floppies
But frankly, I don't get so many bad floppy.

[djbase]

Yes, that top shield must (or should) be removed. But what other shield is there around? I know only that one in the pictures above.

[alexh]

That shield comes in two pieces. The big main one in these photos and an extra rectangular one just a little bit bigger than the floppy disk drive which it covers. The two almost mate up just next to the speaker.

It's OK to leave the bottom one as it is.

Oh, on my is a small piece of metal that covers part of the fdd.
That have to come off too as it seems to be mounted on the larger one.

Any chance of getting one card for my soon to arrive Falcon 030 DJbase? I've send you a email. Thanks.
