Sold A3000D 16mb Ram boards

[Marmes]

Hi!

I have for sale 8 boards like shown in this thread:
https://www.amibay.com/showthread.php?94227-A3000D-Ramboards
I will take more detailed pictures later.
They are based on SpeedGeek design.
Before I send them they will be tested of course. Since this is a DIY thing, I cannot give warranty, but I do repair it in case of malfunction.
When assembling this you must know what you are doing. They are bit hard to insert, you have to apply some force. I will not be responsible if you break something or cannot put it to work. I already installed one successfully in one member's A3000D. (Trixster). As you can see, I can use an accelerator on top of it.
After I sell them all, I will revise the design and give gerbers for free for those who might want to make more. I will not make more in the future.
I will ask for each 40€ plus postage and paypal fees.

Could you specify exactly the type of DRAM chips used and what exactly is U9 ?

I sincerely hope you don't use the big squarish pegs you have used in your previous boards because they can damage the ZIP sockets.

There are inexpensive pin headers of the right size on eBay. See: https://www.ebay.com/itm/171830872054

Eslapion, I explain all in the thread. FPM Dram and U9 is a gal16v8.

Those will not work correctly, I have them, and didn't work, the ones I use are good and get good contact with old zip sockets.

I searched for 'A3000 RAM boards' from SpeedGeek and found 3 threads:

• A3000/4000 1MB ROM Mod
• SuperBuster Zorro2 Speedup Mod
• A3640 @ 50Mhz!

None of these are related to what you are offering.

If a GAL is required and this is a DIY kit then the JEDEC fusemap is required.

Yeah, they may be too thin for some types of sockets.

If you look at a post from Buzzfuzz you find 3 photos and there is another adapter of a similar kind with pins that are thicker than the Chinese ones but not as big as the square ones.

AFAIK, the square ones are really designed for SCSI/IDE/ATA and floppy disk ribbon cables connectors.

The ones I use are slightly thinner than those used in SCSI /IDE connectors.
