Unknown RTC card

[Ruud]

I have this card already since the '90s and only rediscovered it yesterday:



Does anyone recognize it and, more important, knows what software it needs to be able to use it?

Thank you very much in advance!

TP-005, using an Oki M5832 as the clock chip.

Some of the clock software at [here] is for an Oki M5832. Maybe one of those will work. It will depend on whether or not the software looks for the M5832 at whatever I/O base address your card has the M5832 sitting at. And maybe the jumper on your card allows the selection of two possible I/O base addresses.

I maybe should have mentioned that but of course I tried those. I just hope that somebody knows that card and has the software. Next stage: re-engineer the card and write the software myself.
Thanks anyway!

Sorry for a small side-quest, but do we know if the TP-xxx was a series of expansion cards of some manufacturer? Immediately as I saw Ruuds' card I thought of this RAM board that I have which has suspiciously similar model number of TP-003 and the PCB looks very similar.

(I haven't been able to find a manual for this board and thus haven't been able to get it working)

Most often the M5832 is hung off of a PPI of some kind, due to how slow it actually is. If they've managed to make it work reliably directly connected to the bus then maybe software meant for the M6242 may work if you can identify the port.

I think this 74LS273 does this job.
