405A MEMORY CARD (PN 181-6364)

THIS CARD IS THE FIRST ADD ON MEMORY CARD FOR THE Z-286. THE
Z-405A COMES WITH 128K (64k x 9 x 2) MEMORY, WHICH CAN BE
USED FOR EITHER BACKFILLING THE BASE TO 640K ,OR EXTENDED
MEMORY. 512K OF EXTENDED MEMORY (256K x 9 x 2) ALSO
COMES WITH THIS CARD.
THERE ARE SOCKETS TO ACCOMODATE ANOTHER 512K OF EXTENDED
MEMORY, THEREFORE, TOTAL MEMORY CAPACITY ON THIS BOARD IS
640K BASE, 1024K EXTENDED, OR 512K BASE, 1152K EXTENDED.
MEMORY CHIPS REQUIRED FOR THESE SOCKETS ARE 256K X 1,
120 NS. NOTE THAT THESE BACKFILL MEMORY CHIPS ARE PROVIDED
WITH A Z-415.
BOARD LAYOUT IS SIMILAR TO THE Z445 MEMORY CARD.(SEE 248S)

J403 FIRST MEMORY BOARD NOT APPLICABLE FOR THIS BOARD
J404 ALWAYS INSTALLED
J405 BASE MEMORY 640K BASE MEMORY 512K


Z-415 MEMORY CARD (PN 181-6360)

THIS CARD CAN BE USED ONLY AFTER A Z-405A HAS BEEN
INSTALLED. IT COMES FULLY POPULATED WITH 1.5 MEGABYTES OF
RAM. 18 256K X 1 CHIPS COME WITH THIS BOARD TO FULLY POPULATE
THE Z-405A. BOARD LAYOUT IS SIMILAR TO THE Z445 MEMORY CARD
(SEE 248S).

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
