NEW Genuine old stock 5 x IC's *** ONLY to be used with early 520 ST model *** *** NOT for 520 / 1040 STF / STFM / Mega or STE *** Atari 520 ST DMA 40 pin DIP controller chip Found in the early 1985 type 520 ST with external PSU and FDD P/N: C025913-20 The STE "bad DMA myth" This DMA chip was used in early STE's but a problem was found that hard drive data could become corrupted with this chip fitted, It was never the chip at fault as it was clearly used in the ST / STF / STFM and Mega ST with success, Atari used the same DMA chip in the STE (as manufacturers do to keep costs down) but the STE's circuit didn't work well with it so a modified DMA chip was designed for later STE's Any questions - please ask.
