There are PROM files on that Web page. Herb Johnson Sept 2015. --------------------------- The 82S181 is a 1K X 8 fuse link 5V PROM. It has almost the same pinout as the 2716 series UV EPROMs - BUT - some 2716's use multiple supply voltages. A Thompson/Mostek TE2716 is a 5V only PROM which is nearly compatible with the 82S181. Here's the adapter wiring to use to read 82S181's as a TE2716 All pins go "through" except for the two connections at pins 18 and 21. 82S181 pin ET2716 Vcc ------- 24 -------- Vcc A8 ------- 23 -------- A8 A9 ------- 22 -------- A9 /CE1 ->GND 21 Vpp=5V /CE2 ------ 20 -------- /OE CE3 ------- 19 -------- A10 CE4 -->+5V 18 /CE The adapter is a 24 pin socket with pins 21 and 18 cut off. Pin 21 of the socket is wired to ground (pin 12) and pin 18 of the socket is wired to Vcc (+5V pin 24). Take care that the cut pin does not contact the ZIF socket of your programmer. Wired this way, when the programmer enables the 2716, the 82S181 will only be enabled when A10 is high. Consequently the first half of the imaged 2716 data will be "blank", and the second half will have the ROM image of the 82S181. It could be wired other ways but this is mechanically simplest.
