The Super 1750 Clone was a 512 kB RAM expansion unit designed as a tiny, but compatible, third-party replacement for Commodore's then out-of-production CBM 1750 REU. Manufactured by Chip Level Designs, the Super 1750 Clone was sold by Software Support International. * Used the same MOS 8726 REC (RAM Expansion Controller) chip as the Commodore REUs. * Worked on the C128 and the C64. * Rather than 16 chips of 256K×1-bit DRAMs, it used four 256K×4-bit DRAMs (in ZIP packages). This gave several advantages over Commodore's original REUs: * * Less power consumption, so did not require the C64 to be upgraded with a heavy-duty power supply to use it. * * Much smaller; the plastic case was the same type used by the Epyx ''FastLoad'' cartridge. == External links == *(c64.org: Super 1750 Clone User's Guide (text) ) *(c64.org: Super 1750 Clone User's Guide (zip file) ) (eText) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Super 1750 Clone」の詳細全文を読む スポンサード リンク
