I still have occasional use for MC68705 (NMOS EPROM-based) MCU's, and the programmers are "out there" if you want one, albeit not cheap, and the hand-built ones, specified in the datasheets and elsewhere, cost about $15 to build (They once cost about $3, but that was when a dollar was a DOLLAR and not just the price of a candy bar. Of course, using ZIF sockets would octuple the cost.) and still work just as well as they ever did. It takes an hour or two at most, to build and verify one.

You can buy a Data I/O Unisite, or any of a number of other programmers that handle the old NMOS MOTOROLA MCU's, as well as thousands of other devices. I've got one, and it works just fine. Data I/O wants upwards of US$40K for one, and by the time you have all the "options" you need, it can be half-again that much, but eBay provides other (~US$300) options. You do, in any case, have to know what you're buying, but that's always the case.

I had a fire at my home/office some years back, which destroyed all my computers, printers, and my file server, and, all my on-site backup materials. I was up and running, well on the way to recovery later the next day. A lot of my databooks were lost ... they were the only thing not replaceable, since component vendors didn't print the really important information after the first few years.

I don't know what the guy's problem is.
