Yes, they should be in the slots near the SCSI connector

The Quadra 700 can only use 256k SIMMs. You can however have only 2x 256k to bring it to 1Mo.

@franklyn I refunded your second order, your replacement has been sent. Thanks for your trust.

@franklyn, reach out to me, I always exchange defective products. I do test everything before shipping of course, but it's impossible to get it 100% right. Sometime damages happen during shipping. Some of my products are made using original new old stock components like VRAM, they are 30+ years...

I do not think it relates to macsbug. It's an issue between the VRAM and the Mac LC. Glitches should occur within the finder when dragging windows around as well.

There is a known issue with the TSSOP version of my VRAM, which uses NEC chips, and the Mac LC. A customer reported it to me several month ago and I have been able to replicate this on a LC that I have purchased since. Other macs are unaffected. The glitch appear when a window is moved, and...

Good, I don't really like white soldermask except when the application justifies it. I wonder if they've been able to enforce that trademark!

I've been interested in making one for quite a while, I have a pair of 4MB DIMM but they have chips on both sides which is not ideal for assembly. That white module would be more ideal, I did not had the energy to route one from scratch which is why it has not been done yet. I also lacked a test...

At least, for my products, federate a group order to share shipping could be a solution. I am not happy to have to charge that much for shipping, this is my cheapest option actual cost :(

As soon as La Poste have a solution for us to ship, fingers crossed!

I make the MacBatt, but shipping to the US is a bit problematic at the moment. https://www.tindie.com/products/jurassicomp/macbatt-internal-cr2032-pram-macintosh-battery/

I have placed 16MB in my SuperMac Thunder/24 and can confirm that only 8MB are seen, so 8MB seems to be the maximum amount of GWORLD RAM supported. I have a RasterOps as well, I need to find the drivers and test it, there's some damaged pins on a QFP so it may need a little bit of repair before...

Yes I have, I need to list them... You can DM me here as it will be faster. I have about 20 at the moment. Thanks for checking in.

Hey everyone, sorry for letting things up in the air for a while. I actually now have a working 4MB design, my original PCB had an issue with A9 which was not impacting the 1MB SIMM. My supplier ran out of 1Mx4 RAM chips. I have been looking for options but I hope I can have a batch made by...

I had very limited supplies of 16MB SIMMs so I have only sold a couple kits to friends and people asking directly, but I have never listed them. I am planning on having a steady supply hopefully around June. @mousehouse yes, modern PCB makers only offer 1.20mm instead of the 1.27mm standard for...
