A replacement board for the 2 DRAM chips on C64 and C64c boards 250466 and 250469 is now available.
This little board replaces the two 64k x 4 bits DRAM ICs with a single static RAM IC. Accordingly it consumes only a trickle amount of power, about 5mA. It also acts as a VSP bug fixer.
The product's name is SaRuMan-64 and it costs 13.25$US or 12 Euros.
Get 20% off when you order 5, 25% off when you order 10 or more. Distributor pricing on 25 units or more.
Shipping cost is the same as with PLAnkton; shipping a small packet (up to 12 units) to the US is 8$. Shipping cost for Europe, Australia and South America is 10$US or 8 Euros.
Get a 10% discount on up to 3 PLAnktons if you order them at the same time.
The product is strictly shipped with antistatic protective packaging. It is covered by a 90 days money back guarantee and a 3 year replacement guarantee afterwards.
NOW SHIPPING!

Re: SaRuMan-64 C64 static RAM for DRAM replacement board
Ray Carlsen has used on of my modules to replace all 8 DRAM ICs on an older board 250407.
The 8 DRAM chips needed about 240mA of power in all. The single module now uses less than 5mA.

Saruman-64 is now fully compatible with the Kawari VIC-II replacement module. Please make sure you have firmware 1.18 or higher,
