15 left from first batch. One buyer installed on the Reloaded MK1 and works fine.
 
Hello.

I've a C64. it's extend the ram, replace the old one ?
Will the c64 much better ?

It replaces the old DRAM chips with new SRAM chips.
Fixes the VSP bug as a bonus (the new Super Mario Bros conversions uses VSP. Mayhem in Monsterland is one old game famous of using VSP).
Decreases power consumption.
Fits motherboard revisions 250466 (last big motherboard) and 250469 (all smaller motherboards).
 
Sold out at the moment. Will receive new batch around mid November. These boards have worked well with both 466 & 469 boards.
