SRAM MODULE is my 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

 

Disclaimer: 

  • If you:
    • are not familiar with soldering
    • do not have proper tools
    • do not understand STEP BY STEP instructions 

          please LET a pro technician do it for you or send me your ATARI BOARD for installation. Upgrade installation cost            is 10€ only. Contact me to arrange installation.

  • Please remeber - wrong tools usage or low skills may damage atari 
  • Any damage / harm to your hardware is NOT subject of any kind of warranty.
  • Installation is very easy, but unexperienced hands can do a lot of damage. Please, do not ask me questions WHAT HAVE I DONE WRONG WITH INSTALLATION - answer will be always the same -

 

I DO NOT KNOW

 

 

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  LSP1 point at sram module  to  CAS_INHIBIT SIGNAL (for example MMU pin 16)
  • ready :-)

 

ps. handy article https://www.evilmadscientist.com/2010/basics-finding-pin-1/ if You do not know how to identify pin 1 in chips. PIN 1 always goes to Pin 1
