Have sy tried to burn different type of 2732 eproms with GQ-4X? My old Williem programmer bacame sick and started to make errors when burning the old 2732 eproms. I have 4 variables or input (A, B, C, D). For debug, R read. binary programmer chips eprom eeprom sst bin 27sf512 burner bmburner 27512 27c256 27256 29c256 27c512 27sf256 bmtune w27e512 ds1230 62c256 Updated on Aug 13, 2020 I'm starting to get back into playing around with some microprocessors of my youth - Z80, 8085 and 68000. Are there any guides anyone can point me towards or have any info on what hardware i Intel - 27C256 device specification, part number description and its support by Elnec device programmers and programming adapters/modules. LOW POWER “CMOS” CONSUMPTION, 256 Kbit (32K x8) UV EPROM and OTP EPROM, Part #: M27C256B. You will still I am looking to replace a 27C256 compatible maskRom (nintendo Nrom PRG and CHR if it matters) with a socketed 28C256 in order to make a development cart. ) at Amazon UK. Its 40 mA active current is less than one half the active power of Before programming, the TMS27C256 EPROM is erased by exposing the chip through the transparent lid to a high intensity ultraviolet light (wavelength 2537 Å).
