I'm new to the SAM COUPE group and wondered would anyone be interested in making a homebrew SAM-COUPE ?? It would have an improved spec. on the original: Z84C0020 20MHz Z80 512K SRAM ( KM68400,K6T4008 etc) 64K or so EEPROM W27C512 CPLDs as glue logic for video, memory and I/O decoding, serial and parallel input,output RS232, LPT1 etc SAA1099 sound chip V9958 +128K RAM as second VDP for sprites etc possible using a micro-controller for PS/2 mouse / keyboard and joystick input. Should cost about £30 for ICs and stuff plus another £50 for a one-of prototype PCB. Anyone interested ?? Best Regards
