I noticed nvram replacements for the TDS784D on ebay

You can tell there is a chip on the bottom. But you can't see what it is. Probably the ram.
Then there is probably something else under the battery.
It would be nice to be able to roll our own.

Assuming that 8 pin IC is a RTC, it's gonna need a microcontroller to talk to that and talk to the parallel bus. Actually this might not be all that hard to sort out just knowing what we know. Microcontroller to connect to the 8 data lines and chip select, enough of the address lines to decode when the RTC registers are being read. Some of the modern microcontrollers should be fast enough to directly talk to the parallel bus. Then you need a SRAM and power control IC.

Is it really worth the time when you can buy it ready to go for 100 bucks ?
radioguy123:
Yeah you're probably right snoopy. He will even load them with the software of your choice.
Just handing over the money won't help you learn anything though.  ::)

It's not really worth the time, but I'd still prefer to roll my own, I just like doing things that way. Also I'm curious how it's done.
