Only 4MB SIMM and dry transfer can be sent cheaply! Add shipping method:

- This is non-standard shipping with tracking.
- It will be treated as a document or CD, and there is no damage guarantee. *Up to 8pcs in thickness.
- If you want this to be sent with other items, it will be a regular shipping method.

It's a last resort because shipping from Japan is limited...

- 7USD up to 100g
Example: 4MB SIMM Card x4 = 100g

- 9USD up to 200g
Example: 4MB SIMM Card x8 = 200g

Select the shipping fee again on the payment screen. At this time, if you purchase anything other than 4MB RAM SIMM Card Kit, we cannot send it by mail.

Additional Info: 517409 (T.I. TMS) works!

@Branchus made a great Youtube video. Watching his technique is very educational for VintageMac enthusiasts, and since he's been soldering SOJ's repeatedly, it's easy to see how it works!

Thank you @Branchus

So, the memory speed will depend on the donor chips, correct? For example, the SIMMs I have are 60 nanoseconds yet the chips back then are slower because the Macs back then didn't need 60 nanoseconds. Hmmm....

Correct. The speed of your donor SIMM’s RAM chips determine the speed of your DIY SIMMs. 60 ns is fast enough for any Mac that is compatible with 30 pin SIMMs.
