The PC532 was a "home-brew" microcomputer design created by George Scolaro and Dave Rand in 1989-90, based on the National Semiconductor NS32532 microprocessor (a member of the NS320xx series). Full hardware documentation for the design, including schematics and PAL programming data, was made freely available, and a short run (around 200) of motherboard PCBs were produced for hobbyists to populate and assemble into fully functional systems. == Hardware specifications == * PC/AT form-factor motherboard * NS32532 CPU and NS32381 FPU (25 MHz) * 4 to 32 MB of RAM * National Semiconductor DP8490 SCSI host adapter * Adaptec AIC-6250 SCSI host adapter * Four SCN2861 DUARTs (providing 8 serial ports) * 27256 32 kB firmware EPROM 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「PC532」の詳細全文を読む スポンサード リンク
