I've purchased this modified 256k RAM Silicon Disc from eBay (naryanworld) after successfully winning the auction for £93 with £11.00 P&P and this works perfectly with my upgraded [[Dk'tronics_memory_expansion|DK'tronics 64K RAM pack Memory Expansion]] >> [[Upgrading_a_Dk%27tronics_RAM_Expansion#The_Conversion|256K]] and I've turned the switch down to RAM DISK position in order have the full total of 576K (552K available memory to use) when using [[ParaDOS]] (accessed by the |DRIVE command without any parameters) for easy quick checking.
