  • 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

Step by step: 

  • REMOVE old RAM CHIPS ( hint: not necessary actually; if your ram does not get hot, You can remove resistors on data lines to ram and keep ram chips intact) 
  • Connect CI point at sram module  to  CAS_INHIBIT SIGNAL (for example MMU pin 16)
  • install SRAM MODULE under MAIN CPU; insert CPU to SRAM MODULE
  • 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.
