S100 2716 programmer was Re: IBM MST extender cards
I thought I might have had some notes of the S100 2716 eprom programmer I mentioned (dad just called it the eprom burner) somewhere, and sure enough I did. I'm surprised they didn't go along with all the peripherals and doco when the S100 machine was sold sometime in the late 80s. It's on foolscap paper, an unwieldy paper size nowadays and I don't miss it. The burning code is 5 pages of z80 assembly, a few 2716 write timing diagrams, miscellaneous wiring diagrams and a rough block diagram of the thing, which I have just scanned here. It used an 8255 PPI: http://web.aanet.com.au/~malikoff/S100_2716_eprom_burner/S100_2716_programmer_block_diagram_sketch.png Steve

We definately had this tool on the bench when doing the eprom programmer, I think we also had another one or two that had a spinning end, like a pin vise arrangement, they might have been blue, or we used blue wire. It was so long ago now. Steve

One of mine has a gold coloured handle, but is otherwise very similar. I can't remember when I last used it. Somewhere, I have a box full of wire wrap tools. I keep meaning to dig it out and go through it, or at least drop it off at the local consignment place, but I never seem to get round to it. There always seems to be more to do than there is time to do it in. Heck, I'm only replying to this because I'm off sick, today! -- Robert

Somewhere a friend has a bag with 2 paper clips, and a FRU for that, as well as another one with 2 rubber bands. From an upgrade from a 9221 to some other processor that showed up at our place. All of that made a banker box full of crap that the IBM guys were going to toss, since of course they didn't need it in our case.

Oh wow, what a great resource page :-) What I kind of meant to imply was "but doesn't *everyone* have one?" Sigh. It's probably over in the same closet as my ear trumpet ... mcl

I am not sure whether you meant "don't just own" or "just don't own", but the last time we used it was to wire wrap a 2716 eprom programmer S-100 board we designed (ok, he designed, but I helped build it) back in about 1981/82 or so. I haven't seen or thought of it since then, but seeing it in the photo instantly brought back the memory of it. I have some of the tools, others have gone missing, for instance the large tool bag at the rear of the first photo on https://slx-online.biz/hursley/ce-data-list.asp?hur_archive=2 But I do still have the tool bag identical to the one in the foreground, in the same russet brown colour but the zipper canvas has dry rotted.
