    Hello to anyone still out there on this thread. I have been searching the Internet high and low for gerbers and rom image dumps in order to build an AP-64e. Seems like Apple II card-based burners are hard to come by these days so DIY is the best
    solution. Does anyone here have board gerbers and/or the ROM dump?

    Thanks in advance.

    Mark, unless it’s “against your religion,” I’d recommend getting a GQ-4x4
    “USB Universal Programmer”, which is very reasonably priced and supported by Windows software. It can easily read and burn EPROMS (and much else).

    I have had and used several Apple II EPROM cards, and though they
    programmed the parts of the day well enough, they were not (able to be)
    kept up with memory densities and technologies, even prior to 1990.

    I still have the AP64E ROM on my google drive https://drive.google.com/drive/folders/0B9r6vH-4NK4NZGRjNjA1YzItNzgwYS00M2I1LTk2MjMtNjY4NjQ5ZDU1ZTZj?hl=en&resourcekey=0-PVqPB7KwJPxQU-_baMOGTA

    Hi mark,
    No gerbers here but you can find the schematics on Asimov /pub/apple_II/documentation/hardware/schematics/AP-64e EPROM Programmer-Schematics.pdf
