JP1 Remotes

Would it be possible to add 2k eeprom to ReplayTV 5000 remote?

Sure, just be careful removing the old chip as it's easy to tear away the traces from the PCB.

Thank you Rob!
What chip do I need to use for ReplayTV 5000 remote? Would it be possible to use 8k chips?
I love ReplayTV 5000 keyboard layouts!

There's no point in using anything larger than 2k because the remote won't be able to read more than 2k of the memory, and it might have trouble reading the chip at all if it's larger than 2k, so stick with a regular 24C16 type chip.

I tried to rebuild ReplayTV 5000 extender for 2k eeprom, but it is not working!!!!!!!!!!

Please help!!!

I uploaded all my project files to diagnostic area http://www.hifi-remote.com/forums/dload ... le_id=4232

Are you saying that the extender isn't working (ie, it's an extender problem and I should move this to the extender forum) or are you saying that the EEPROM itself isn't working (which means you messed up the soldering)?

Remote is working if I load old 000 3ff image, but if I use extender with 2k address, 2k image is loaded ok and IR accepts new device updates but remote keys do not generate any signal. I activated remote by pressing tv and power keys.

OK, so the mod is OK, which means it's not a hardware question anymore. You've tried to modify the extender for the 2k chip and it's not working. For this you'll need help from the extender writers, so I'll move this thread into the extenders forum.

I modified RDF and extender assembler file to reflect new address $800, then I build new Original 2k image by adding FF to addresses $400 - $7FF. Then I modified Original RDF 1k to Original RDF 2k, compiled and merged 2k extender with 2k Original image. New 2k image was loaded successfully with IR 6.2. Then when I added new devices and tried to use them, but any key strokes do not generate signal and LED is not turn on by key presses.

Oop's. I forgot to ask is it possible to use original ReplayTV 5000 extender 1.2 with new memory settings or extender need to be modified to work with 2k of memory?

The 1K extender will work with 2K, but it can't use the extra memory.

I'll have to check the code and try to remember which vars need to be changed because it's been a long time since I wrote it.

I'll try to post it in a few days.

Thanks a lot for help!

ok..., I now remember this:

In addition to the eeprom size in the RDF, you also have to change the shift key patch address and the device button addresses.

You can get those values for your version of extender by looking at the values of Shift_Key_patch and DevSetup_patch in the listing file generated by the assembler. DevSetup_patch is the base address of the device button table, the first address of the TV button.

Thank you!
Thank you!
Thank you! Awesome!

I finally have replayTV 5000 remote with 2k of memory. I desperately needed space for 2 more devices!

Good work, and thanks for jumping in Hal. Woody, be sure to gather all the necessary files together into a zip and add it to the R5k extender folder.
