    Does anyone have a ( 18CV8P ) programmer

    I look for someone who has a programmer that can program a couple of these chips for me

    If someone has a programmer I will give more details

    I not sure where to post this if not in the right place please move it to the right place thanks

    Is this a GAL? If so, an (ancient) HiLo ALL-07a takes AMI and GOULD PEEL18CV8, Hyundai HY18CV8, and ICT PEEL18CV8 and PEEL18CV8Z. A (just as ancient) DataIO Chiplab takes these as well, with exception of the ICT PEEL 18CV8Z.
    Problem is both programmers connect through the LPT-port, which modern mainboards don't have anymore, and their DOS-based software programs the LPT-port at low level. It takes some tinkering to get them working in a Win DOS-box on versions newer than XP.
    The TL866's device list doesn't mention these types.

    Is the P at the end of the chip type designation relevant? If so, you'll have to study the datasheet to find out if the types listed above will actually be suited as a replacement.

        So, it's not a GAL, but a PEEL PLD. Looks like the P at the end of the chip type designation just stands for 'Plastic' (i.e. the IC casing). As long as you obtain a (NOS?) substitute of the same speed category, you should be OK. Be aware that Ebay and AliExpress are littered with relabelled fake components, be it transistors, IC's and even passive components. Buy from a trusted reputable source.

        Note as well that PAL's, GAL's and also this IC, have a security bit built in, which prevents their contents from being dumped. Check datasheet page 4, under 'Design Security'. You can't copy it like you'd do with an eprom. So, you first need to get hold of the (verified to be correct) data that you want to program the IC with.

        Strange that the TL866 doesn't support this IC, neither does its successor (TL866 II)

          Supposedly my universal programmer supports the ICT PEEL18CV8Z but never tried it... unfortunately I know my programmer has bugs because try as I try, I can't get the likewise supported AMD PALCE20V8 working. It appears to erase but fails to program.

          AMD PALCE16V8 and Atmel ATF22V10 both work in my programmer however, never had others to try yet... I wrote my own logic for them so no legality or readback problems

          Oh, and yes, my programmer is connected to an old PC with a parallel port...

            Can You give this a try and see if you can read the chip that I have

              What do you expect from it?

              I'm not sure if it's very legal to copy them, but I'd give a shot if you gave me a JEDEC fuse map file for one and a blank chip... but no guarantees, my burner could really burn them ...
