4 x 64Mbit = 32Mbyte

My mistake... I should probably know this stuff about tech by now. 😢

I'd be down for one if it had 32MB soldered directly onboard. I have two of the originals but once they're fitted with a SIMM they're WAY bulky. A 'slimline' model would be really appealing.

What if the memory chip dies? A socket makes this problem easy to fix!
Does anyone have the "gold" version but wants the "value" version? 😎

Imho the added costs and inconvenience don't compensate for a potentially little bit easier solution for such a low probability failure 😉

The cost difference is neglectable and it makes it last considerably longer.
As far as I understand this is for collectors / enthusiasts and not for consumers.

Personally having had the "old" simmconn style and how it makes the dimms stick up so high on the cards, I hate it to bits. I would much much much rather have one flat PCB with the maximum ram chips soldered directly to it. The way with the old style in my retro system with my awe64 gold, it makes it so -all- of my ISA slots are used up, and I can't use any other ISA card.

So most definitely, if anyone remakes this, use the soldered-on-flat ram style, it would be a great improvement.

FYI the original creative ram cards had the chips soldered flat to them too, it covered 80% of the card.

Either way is fine to me, go with whatever is cheaper (which I guess is the soldered on method, as it won't require SIMM slots?)

For those that don't quite understand the difference. This was creative's Original 28MB expansion module:

And here it is with the SimmConn:

While the SimmConn does work.. it prevents full size cards from being used in adjacent slots, the one downfall of that solution.

If we could get something with flat ram chips soldered on the PCB, similar to the original design that would be much better.

And thanks to the higher density chips we are not obliged to use a handful of those beautiful 2mbyte soj's, I guess the solution could be made with as little as 2-4 ram chips in total.

Lads, just google for edo price and forget about ct1950 replica

By the way 16mbit is limit for edo chip

Hmm. What about all those widely available EDO SIMMs with higher density chips?
E.g.: http://www.ebay.com/itm/262383657484

You're right. I was not clear enough, mean 1mx16 limit for existing logic. With using these high density chips programmable logic has to be redesigned. It's lot of work

If you save some money on parts, you'll have to invest in development and vise versa

Do you think that if someone takes this SIMM and installs it into the existing SIMMConn it won't work? I haven't checked that, just curious.

My opinion is, not all ram will be detected. Good idea to check it

Why not just use right angled simm slots?

Not like they are hard to get.

I don't know why they weren't used on the original ones, maybe price. But it's already been documented.. we can use the smaller surface mount ram chips on the PCB for a newer re-design, but would be complicated.. but production costs would be down vs those slots.

Can anyone communicate to me what the GAL part number is?

Either a typed copy of the IC's writing or a hi-res clear photo of the square chip.

Thanks

Also, without actually owning a SIMMconn... I may need help from someone who does, specifically using a DMM to test and confirm connectivity between points.

I can map the PCB from images to the best of my ability but where the traces go under other parts and out of sight... this is where a DMM comes in handy.

Thanks again

The full parts lists is available from the original maker as well as from the post I made with the link to the updated format for the circuit board files.
Simmconn AWE64 Adapter

The original maker also posted in this thread about a part (the GAL) that is no longer available and with the newer part that would work.
Simmconn AWE64 Adapter

Just read through the thread and you will be able to find the needed info.

So.. Is anyone willing to build a batch of these through Kickstarter?

Should just do whatever is cheaper and/or easier to get out the batch, whether it be onboard memory or slots.

It is, and will be possible, only it will not happen overnight. I work full time and have dependants by way of family.

I will make a batch, either myself or as part of a team, but as a project it could take months. There does not seem to be many people interested so I imagine the batch would be fairly small... i.e. 10 to 20 pieces.
