I've purchased this modified 256k RAM Silicon Disc from eBay (naryanworld) after successfully winning the Amstrad CPC 464 / 664 / 6128 Silicon Disc drive (RAM DISK / BANKED RAM) RARE! auction at 26 Sep, 2020 21:35:56 BST for £93 with £11.00 P&P and this works perfectly with my upgraded DK'tronics 64K RAM pack Memory Expansion >> 256K and I've turned the switch down to RAM DISK position in order to have the full total of 576K (Free / Total buffer: 552K available memory to use) when using ParaDOS (accessed by the |DRIVE command without any parameters) for easy quick checking on my Amstrad CPC 664 after receiving on Wednesday 30th Sept 2020 afternoon.
