256k*16 = 4096 MBit not 4096 Kbyte

That looks like a mighty nice mod! Very clean and leaves your trapdooor ready for other expansions, like an accelerator. Good one!

alexh · 16 June 2008, 22:28

The A600 trapdoor edge connector doesnt have the signals for an accelerator, but you could make a clock port adapter. (Kinda like the one on the A602 from Jens Schoenfeld)

Amiga1992 · 16 June 2008, 22:29

Oh you are right.
But doesn't the A600 have a clockport as well?
I am so confused, haven't opened mine in years :P

i need to update it.

Just a tip for everyone who wants to create A600's trapdoor devices: the peecee PCI slot have the same pin space of the old A600 trapdoor's edge (albeit a little longer). If you have a peecee mobo around, it is simple to unsolder one PCI slot to use on your own hackery!

Hungry Horace · 16 June 2008, 22:42

bagh! cant find any compatible chips in my collection!

Zetr0 · 16 June 2008, 22:45

@HH

....sigh.... do you READ those lovingly crafted PM's i sent you.... not just the ones with the extra kisses....

I have a set already with 30AWG wire just needs plonking on and Soldering.... I said... you could have them for postage.....

now.... no more kissy PM's without flowers first....

shessh..... specky fanboi's i tell ya.....

Hungry Horace · 16 June 2008, 22:48

i guess my speccy eyes were paying to much attenetion to all the kisses and PDF links to notice!

DoogUK · 19 June 2008, 22:27

I'm looking at doing this mod but there's one bit i dont understand.

Do you solder wires to pins 28 & 29 on both ram chips? and if so why are there only 2 wires coming out.

Sorry for noobiness

Zetr0 · 19 June 2008, 22:36

pins 28 of each chip are connected together, pins 29 of each chip are connected, there are 4 wires total, 2 from each chip.

in the picture, there are two wires from each chip to a simple bit of perf board, and then one wire from that to the mobo.

I have since re-done this using 30Awg wire, which i had none of before, just need to update the pics.

DoogUK · 19 June 2008, 22:40

Ahhh thankyou grandmaster hackery....i went through the german pages and couldn't figure it.

I'm going to do this mod.

@ Doog

That's why Zet and I translated it....

DoogUK · 19 June 2008, 22:55

@Merlin....i know and muchly appreciated mate...but i couldnt get the clear picture.

Killed too many brain cells i think.

My a600 board is a rev 1 and marked as an a300 ...will this still work on this board as the instructions i think were for a rev 2.

Magno Boots · 21 July 2008, 00:02

Just to clarify an earlier post.

I blindly purchased six S3 Trio cards off Ebay and found that the chips are not compatible with the A600 upgrade

.

Are these of use to anyone before they go in the bin?

cosmicfrog · 21 July 2008, 01:28
