HERON RAM Upgrade expansion board is 16 MB RAM module for Atari ST. Due to the hardware limitation of the memory management system offered by the original MMU chip, STARI ST can only use 4 MB, however after replacing the MMU with RemakeMMU (in development) one will have 10 MB (MEGA ST) or even 14 MB (future plans).
Compatibility
- The extension is compatible with all Atari ST/STF/STFM and MEGA ST.
Disclaimer:
- If you are not familiar with soldering or you do not have proper tools, please LET a pro technician do it for you or send me your ATARI BOARD for installation. Upgrade installation cost is 30€ only. Contact me to arrange installation.
- Please remeber - wrong tools usage or low skills may damage atari and ultimate; any damage/harm to your hardware is NOT subject of any kind of warranty.
- Installation is easy, but unexperienced hands can do a lot of damage.
- I assume You can disassemble Your atari ST, so no detailed instructions or safety precautions here.

Selection of extension borad
- The simplest installation /and only one supported/ is possible with the COMPLETE SET : HERON + replacement board equipped with anti-kickback resistors
- Unfortunatelly, there is no universal solution. Atari ST computers were produced by many factories for a long time, so there are many versions of the board.
- Each version has a unique marking on the motherboard as in the photo below.
