Looking for NEC D416D RAM chip

Hello,

one of the RAM chips in the middle memory row of my rev 2 is different from the others, which really bugs me when looking at it :-)

Does anyone know where I could source one of the gold ones (NEC D416D)?

 

Thanks for any help,

 

Carsten

If he asks me I would send

If he asks me I would send hem only what he needs for lower price. No need to damage a vintage RAM card for parts. Thanks for advertising me in ebay david, have you learned to design hardware properly epecially similar RAM cards?

upd416D

I believe I have one orphan DRAM chip with this number.  I had intended to sell it on eBay but would be happier if it found a home in a working machine.  If interested, I would ship it to you to test and if it works you can pay me a fair price for your piece of mind.  PM me for information or send to orgwood65@gmail.com

 

I found my chip tonight and it is the same number with 827 after the NEC which may be a date code?

So are you interested?
