| Reading a 16L8 PAL / question on early SRAM card |

So I got my hands on a storage device for a piece of chip foundry equipment... I took off the front panel to get at the EPROM and dumped it, but I'm sure I had quite the look on my face when I realized it also has a PAL. PAL16L8A-2CN... circa 1989. I have a TL-866 programmer... but there is no listing in its PLD database for the 16L8 (I assume the PAL16LV8C is NOT the same thing). How would you suggest I dump the equations out of the device? I may end up getting my hands on a second unit, just so I can also get my hands on the SRAM cartridge this used. (it probably predates the PCMCIA standard by a few years, as this storage device was developed in 1988). As for the SRAM card slot, I counted the pins twice... there are only 40 pins. Does this ring a bell? The only clue I have is that the connector has the duPont logo on it. |

Did you see this topic https://www.eevblog.com/forum/fpga/reading-the-programming-of-pal-chips/msg5298922 |

No I hadn't seen that thread... will keep it in mind, but I have 2 other assemblies to reverse engineer first. Thank you! |

A picture of the card slot... anyone recognize it? |

Incidentally, I have access to a BPMicro programmer, and may well be the same unit that was used to program this PAL. The BPMicro software even has a definition for an AMD 16L8 (I assume AMD bought MMI at some point), but I cannot for the life of me see how I can 'read' the PAL? |
