So my beloved logic analyser with the network card died yesterday.
Looks like the DS1387 chips battery has failed.

Re: Logic Analyser Died
That's annoying. How easy are those particular DS units to find? Some of the older ones are still available but the newer ones discontinued (a problem for those trying to keep Sun Ultra workstations running, but older SPARCstations are just fine as the 42T02 is still in manufacture).
Given how often these units run out of battery I'd put a socket in it. (But generally I always do if I'm desoldering a chip.)

Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Re: Logic Analyser Died
I’m not a fan of sockets. They’re v unreliable but in this case it’s warranted. Usually I just solder a new one in.
I’m planning to rework the DS1387 and install a coin battery then reflash with an arduino nano

Re: Logic Analyser Died
Those Dallas battery packs are horrible, they were used in the old cheap PC motherboards also. I am surprised they cheaped out on something like that. Your logic analyzer is running on 68030? Amazing.

It’s a 68EC020RP25...
Yeah I’d like a more robust solution long term

Re: Logic Analyser Died
A bit of tidy drilling if I do say so myself
Oddly the voltage is still about 3.0V but the current date/time was lost

Re: Logic Analyser Died
And i managed to kill the arduino that i was using to reprogram the chip.

OK, so what's the third thing to go wrong?

A terrible fire, of course.
A kludge is a workaround or quick-and-dirty solution that is clumsy, inelegant, inefficient, difficult to extend and hard to maintain.
