 I have several TSC5110s. One stopped working after a period of high
 temps in the lab.  It wouldn't complete the boot process - just
 displayed the spash screen, flashed off, then splash screen again.
 Power cycling gave the same result. Replacing the compact flash card
 didn't help.

 Swapping cards between two units one at a time, there were no
 changes in behavior until I swapped the co-processor card. Then both
 units started working!

 I am not sure what that is about. But I notice another thing - I
 can't change the date/time on either unit. I suspect the CMOS
 battery, but I can't find it. The CPU boards don't have the standard
 CR2032 or anything I recognize as a battery.  When I try to set the
 date/time, the units freeze up and have to be power-cycled.

 Anyone know how to locate the battery on these CPU boards?

 Also, any thoughts on why swapping the co-processor cards made both
 units start working?

 Thanks!

 Jim

 Have you tried swapping the coprocessor cards back? It could be as
 simple as re-seating the cards, which in essence is what happened
 during the swap. I think a swap-back is worth trying.

 As for the battery question: is there per chance a "fat"/ high DIL
 chip in there marked Dallas or ST (SGS/Thompson) ? Those ICs have Li
 batteries in their 'backpack'. Replacing a depleted battery requires
 swapping the entire chip. I think they are speced for 10 years or so
 but generally last longer (at least in equipment I saw them in).

 Re: the board-swapping phenonenon; I'm not familiar with the TSC5119
 but if one swapped boards between a non-functional system and a
 functional system, I'd strongly suspect the board connectors.

 Thanks for the suggestions!

 The RTC is an STMicroelectronics M48T86PC1 which is obsolete. They
 are available from various sources, but not Digikey and Mouser. I
 have ordered some. I just have never seem them before, so I wasn't
 looking for a large DIP package to contain a battery.  Live and
 learn.  I am interested to see if the batteries are good in the
 available "new" parts, since they are no longer made.

 These timekeeper devices were used in a number of HP products in the
 90s,
 typically digital scopes and the 53310A MDA. A later variant has the
 battery in a removable piggyback part but those replaceable parts
 are also
 proprietary so replacement is still a nuisance.
 A number of people have tried to find a solution and there are
 rebuilds
 with cion cells, hacked apart ICs with soldered on batteries, etc.
 Some of
 the devices are battery-backed memory, some have clock/calendar
 chips etc.
 and the replacement PCB option doesn't cover all the variants.

 Hi Jim;
 I am not sure about the exact part number, but if I remenber
 correctly these use a RTC (real time clock chip) that look a lot

 As far as swapping the board, perhaps it was just a touch of
 oxidation on the edge connector. You could try swapping them back
 and see what happens? Although I have seen several TSC5110A exhibit
 this due to a bad power supply.
 Hope that helps.

 The constant rebooting makes me think that the power supply is
 failing. Leaky/bad capacitors would be the most common culprit.

 *****************************************

If you find that there is in fact one of the Dallas or ST real time clock modules "RTC", i have had success in scraping away the epoxy potting material until the batter terminals are exposed on top of the unit. Sever the positive battery terminal tab and solder an external wire, then repower it with an external cr2032, with common ground. I have done this on old pc motherboards because of the risk and complexity of removal and replacement on a high density motherboard.

M48T58Y-70PC1 – Real Time Clock (RTC) IC Clock/Calendar Parallel 28-DIP Module (0.600", 15.24mm) from STMicroelectronics. Pricing and Availability on millions of electronic components from Digi-Key Electronics. www.digikey.com As far as swapping the board, perhaps it was just a touch of oxidation on the edge connector. You could try swapping them back and see what happens? Although I have seen several TSC5110A exhibit this due to a bad power supply. Hope that helps.

The RTC is an STMicroelectronics M48T86PC1 which is obsolete. They are available from various sources, but not Digikey and Mouser. I have ordered some. I just have never seem them before, so I wasn't looking for a large DIP package to contain a battery. Live and learn. I am interested to see if the batteries are good in the available "new" parts, since they are no longer made.

Those ICs have Li batteries in their 'backpack'. Replacing a depleted battery requires swapping the entire chip.
