In addition to the chips the Prompro 7 came with, I've had a bunch of other boards and chips laying about my room. The largest was probably a stack of boards from a Siemens PBX that was thrown out and I got to torture. One of the first stumbling blocks I encountered from this was that there was a 1Mb EPROM on it. This is an issue since the stock Willem programmer can only handle 512Kb EPROMs. So, I ordered an adapter board and ripped it. I had a few other large EPROMs, so this turned out to be a good idea. One notable was from a Rockwell Collins Pro 2000-SL transciever/GPS unit that I found cheap ($20 shipped) on eBay a bit back. This unit should prove interesting for a variety of RE purposes since it seems to be military grade. Here is a picture of it:
The until is composed of 4 main board assemblies: power supply (+module), CPU board, GPS translator, and GPS. The GPS translator board is the only board that contained an easily accessible (socketed) ROM:
ROM data like GPS_SOLUTION_LOCK gives it a military feel. A 28F flash chip is also visible. Especially since I broke some of the flimsy cables on the PSU module, I might just rip the unit to shreds and rip all of the chips since its probably a better use of time than getting the unit running anyway. With some luck, there will be assorted ASICs using rare standard cell libraries that I can submit to Silicon Zoo.
There are several types of chips that are still in my rip queues though. The first are 24C SOIC EPROMs. This is what a small group of us has been doing to experiment with some radio units we've been messing with. Hopefully, more on that later as it develops. Although I have some adapter boards, I don't feel like soldering to them each time I want a clean rip. I might be able to get away with just gently placing them on the pads, but really I need a ZIF socket. I'll hopefully be ordering 150 mil and 200 mil SOIC8 compatible (probably SOIC16 and I'll just slide it into position as needed) ZIF sockets.
The second type are 27C PLCC32 type EPROMs. I didn't realize originally that I needed a seperate adapter for those and that the flash sockets wouldn't work for those. Next, I have the stack of MCS-48 combo MCU/EPROM ICs that also require an adapter to work with the Willem. Finally, I have some Altera ROMs I'm trying to rip. The bus pirate might be a good choice, but I actually have some old Altera programmers (Altera Programming Units (APU)) that I was hoping would be a nice way to rip them. Unfortunatly, it seems I can't see to read the ROMs unless I setup a project or something. Lame. Maybe there is a better behaved command line utility in the suite or I can port the code to an open source Linux program.
Of all of the boards and ROMs I've ripped, my favorite so far has come from an IBM RS/6000 43P Model 260. In one of the ROMs, I found the string:
16-6, Go Horns !Probably thought that nobody would ever read that. This ROM I think was labeled 0373.
Take that, Dave
