ColecoVision NTSC DRAM to SRAM Converter Upgrade
$49.00
The Lundy Electronics ColecoVision NTSC DRAM to SRAM Converter PCB mod uses modern, readily available components to replace original, obsolete DRAM. The added benefit of this mod is that it also removes the inefficient need of +12v and -5v required by the original DRAM. All the original DRAM, associated decoupling capacitors, and power inductors are completely removed from the system. The new SRAM Conversion PCB then installs where the original DRAM was located, and specific required pins are then soldered in place on the PCB. The Converter PCB only requires 27 total solder pins verses the original 160 total DRAM, associated decoupling capacitors, and inductor solder joints and is designed to be soldered directly to the ColecoVision PCB without using any sockets. Limit three per customer.
Note: This will not fit in PAL units. PAL version is available here.
What’s included:
- Populated DRAM to SRAM Conversion PCB
Tools required:
- Desoldering iron
- Soldering iron
- Multimeter if troubleshooting is needed
Documentation:
- Installation guide: https://lundyelectronics.com/shared-files/827
- Alternate installation guide for those uncomfortable with desoldering: https://lundyelectronics.com/shared-files/900
Keyphrase: ColecoVision NTSC DRAM SRAM
