Mid Atlantic WANTED: Toshiba Libretto 50CT/70CT 16MB Memory Module

[Kazy]

Been after one of these a while, but haven't had much luck.

Here are the part numbers of compatible units I've found:
Toshiba branded:
NW2056U
PA2056U
PA2051UJ


KTT-LBT/16 (Kingston)
TS16MTL50 (Transcend),
SMT 16MB-L50 (Southland Micro Systems),
MD-EDO-16M--2051 (ACDC)
KTOS50B (Kahlon)


Also if anyone has a busted Libretto keyboard that still has an alt key that would be great too!

Found one! Had to buy a whole other Libretto 50CT but finally have 32MB RAM in my 70CT.

In case anyone else runs across this topic looking for Libretto 50CT/70CT RAM, I found a few other part numbers and some other info.

Other model numbers (16MB):

• T2056 (Viking)
• RT2056 (Viking)
• MGV R60429 T16L1B (or T16L18 -- not sure) (via ebay images)
  • I also can't find this on MGV's archived website: https://web.archive.org/web/19990423170502/http://www.mgvgroup.com/index.html
  • 

Other model number (8MB):

• T2055 (Viking)

Other info:

• Kahlon said, "We used to custom build these but the chips to build are not available to us anymore. At this time, I am sorry that we cannot supply this part."
• EasyCNC emailed back and said they did have these in stock but wanted $350 for them. I'm not 100% sure they're legitimate. https://www.easycnc.net/fanuc/pcb/pa2051uj-hb56sw264t0-6-used.html
• Many other vendors I emailed didn't actually have this in stock or didn't reply. Many sellers of other Toshiba EDO RAM with similar connectors on eBay did reply back but didn't have any of this RAM in stock.
• Occasionally these do pop up on Buyee (broker that will ship and buy Yahoo Japan auctions to US): https://buyee.jp/item/search/query/Libretto 50CT?translationType=1
  • https://page.auctions.yahoo.co.jp/jp/auction/b1109269256
  • Saving the image from that page in case it goes away (there are not many pictures of these RAM modules on the internet.)
