As for RAM versus ROM problems: it might be that the firmware is copied from ROM to RAM before it is started in earnest. I have worked on a design like that in the dim past. Reason for doing this: 32

Hi Peter, I haven't had time to follow all the emails regarding your 3577A because I'm quite busy at the moment, but I'm sending you this email anyway for information, it's a copy of an email I sent

Hear, hear! I would participate in a group buy. In addition, has anyone a recommendation on re-threading the receiving end of these screws? I have done HELICOILs but containing debris from drilling

I'm trying to find a source for the countersunk, odd-shape screws used to secure the sliding top and bottom covers of Hewlett Packard System 2 cases. The screws that are held in place with a circlip

Well, here's something interesting.? I wondered if the unit would run without the fast processor card installed, and it does. Of course, the analyzer doesn't actually function, but it also doesn't

What is a "BUS ERROR" anyway? Guessing this is triggered from the BERR/ input to the MC68000 going low.? A bunch of conditions seem to trigger this but it looks like attempts to write to ROM or

Could be pretty much anything on either of the two largest cards in the analyzer.? Plus stuff not on those cards.? And yes I agree it smells like a ROM going bad.? I wonder if I could pull them,

I ran into the "special service software" issue with a newer R&S transceiver.? Even the ability to swap major assemblies is limited unless you have the special software, which isn't available outside

On HP 8753A, I'm having trouble using front panel interaction to modify an existing cal kit standards to yield a user cal kit (planning 7MM modified to clone 85033D). Looking for help, hand-holding,

Bad trace memory should not give illegal instruction traps. Assuming the trace memory is solely used to store data, and is not (also) used to store executable code in. Unless, of course, something is

Buss errors and illegal instructions smell like bad RAM, ROM or maybe both. Or a bad bus transceiver maybe. Can be other things too, anything dodgy in address decoding, address bus or data bus can

In far off days I used to do the Unix ports for Minitab (back when there was a Unix market). Those were simple days, an executable + some supporting files :-) I always liked Minitab, it was a pretty

Hi all, As rarely happens there is some HP equipment (an 8712 vna and a hp3586) for sale here in Australia. See the https://vkclassifieds.net.au/ website. Regards, Waz
