ah
Never really thought about the DMA socket, is more concentrating on getting it made on just two layers keep board cost low...
I guess it will have to be stacked in a couple of sockets to pad out the gap..

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: DMA port "update" ideas..
Damn I ran out of sockets to stack It only needs one more as the ACSI cable plug housing is higher than the actual socket.
I feel a soldering improv coming on.
Re: DMA port "update" ideas..
So first off - always check the components before you put them on your board. Never assume that what comes in a package is what you expect
The chip I plugged in was a LS244 now that was never going to work. Found an LS245 in my stash of LS' and bingo it is working.
One other thing to mention you have to stack it high enough to get some sort of insulator under the board as it will short on the ACSI connector shielding.
Have been copying files between Floppy and Gigafile fine.
It does fit in nicely next to the Floppy un-f*ck board. You could have one Un-f*ck board to rule them all if you combined them into one.

ah crap I put 244's in the kits didn't I ?!
great to know its working though !

Re: DMA port "update" ideas..
Not to worry - got there in the end
Looking at my LS stash I seem to have a lot of LS244's and LS245's floating around so I was lucky.
Yes - great its working feel a lot better using Gigafile and Floppy together to transfer now.
I don't want to go through that NASTY DMA / BAD 1772 debacle again.
Re: DMA port "update" ideas..
I guess it would be interesting to try this on a STE which is having DMA issues... *writes on 2020 to do list*

Re: DMA port "update" ideas..
Now the 1772 board is in place, it *might* be worth pushing 16MHz into the DMA again and see what happens...

Re: DMA port "update" ideas..
Will look at this today. Is this worth a jumper on the Rev.H board to be able to select between 8MHz and 16MHz?
