The Lundy Electronics ColecoVision PAL 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 156 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 NTSC units. NTSC version is available here.
Included
- Populated DRAM to SRAM Conversion PCB
Tools required
- Desoldering iron
- Soldering iron
- Multimeter if troubleshooting is needed

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.

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.
Note: This will not work in REV J motherboards due to pinout differences specifically to only REV J.
Note: This will not fit in PAL units. PAL version is available here.

Only available for purchase in the USA due to the ever changing current tariff climate, customs fees, and frustrations of navigating it all.
We modify your existing standalone (non-EM#3) ADAM console and turn it into a modern SuperADAM. We painstakingly remanufacture the console inside and out with modern SRAM, drive emulators, WiFi modem, 80-column terminal port, parallel printer port, 1MB RAM expansion, external Digital Data drive, and much more.
With attention to every detail, we create rock solid PCB upgrades, as well as custom 3D-printed bezels, shrouds, assemblies, and parts that create an impressive professional factory-like appearance.
This is a pre-order product and payment is due up front at time of purchase. Once we receive your console, please allow up to six weeks for work to be completed. We don’t rush the process and strive to make every SuperADAM build the highest quality possible.
You must read and agree to the FAQ (Frequent Asked Questions) and agreements before proceeding with this service. Units must be shipped within one week of purchase.
