64k SRAM Module for XL/XE computers

SRAM MODULE is Lotharek's first step to help ATARI owners to repair their computers home, as in most of the cases  faulty is dynamic ram

• replaces base ram of 64KB in all 8bit ATARI
• replaces broken DELAY LINE chip in XL computers and many more ICs - refer to schematics down the page
• upgrades ram in 600XL to 64KB
• PCB thickness is 0,8mm

Inside BOX:

• SRAM MODULE

Step by step: 

• REMOVE old RAM CHIPS ( hint: not necessary actaully; if Your ram do not get hot, You can remove resistors on data lines to ram and keep ram chips intact) 
• install  SRAM MODULE under MAIN CPU; insert CPU to SRAM MODULE
• Connect CI point at sram module  to  CAS_INHIBIT SIGNAL (for example MMU pin 16)
• ready :-)
• EXT - connection to Extension Select is not needed to resurect atari, but sme upgrades may needed: Rapidus or connected to PBI.  Please, refer to chematic of Your computer. 
• PIN 1 is below EXT hole; bottom left at below picture.
