I am looking for one of those GEOS 2.0 ROM chips to plug in my C128DCR, at a reasonable price.
I briefly looked on e-bay but found nothing.
Thank you.

Oops, I meant PM your address and I'll send you the ROM
I'm not asking for anything, so don't worry about that. When I first started getting my C= gear back and I had no serial cables, someone from the old 128 Alive board just sent me a couple without hesitation. When the cables arrived, I was taken back to when we all used to do that in the user groups--we just shared and swapped. I have a blank 27256 that I can burn off and send you.
I'm assuming it will be the 1571 rom since you have a 128dcr? Or did you want to make your own with the romkit and send me the binary?

Thank you cbmguy. I am in CA , USA. I do not have a bin to burn and yes I will used it with a 128DCR so the 1571 will be OK. Details in PM.

Last night the ROM was in my mailbox. This weekend I am going to install it and see how it works. Thank you cbmguy.

It works very well.
Thanks again to CBMGUY.
The picturesd are: 1) The ROM in a ZIF socket 2) Under the ZIF I had to place another socket to allow the lever to close once inserted in the U36 3) The ROM inserted on the board 4) Screen shoot of GEOS loaded. The load time is perceivably faster than loading all from disk 5) Just to see what would happen if the GEOS disk was not there
Next I am trying to understand exactly what files need to be placed in the load disk and which one can be removed. I will want to make a load disk with the CP-Clock driver and a correct Config file.
I want to try to also connect an external C1581 and a REU.

Now you need a DAC and an LED for the 80 column display lol. Cheers.

Thanks for sharing nonefornow! So it seems you need (at least) a disk with DESKTOP V2? I really look forward to more info from you... I think you are on the right track... determine what files MUST be available on disk for GEOS ROM to actually work. Also, your other ideas (test 1581, REU) are good and look forward to your report... but I really want to know what is minimum needed (... we can always add extra stuff, like REU). I'm wondering if CONFIGURE is also needed? I guess it might depend on hardware... I really don't know, but hope you can enlighten us

It took me a couple of 2 or 3 trys but I was able to determine what are the minimum required files in the disk to boot GEOS 2.0 with a ROM chip.
In disk drive A (the internal 1571), in order, CONFIG 2.0 or CONFIG 2.1 depending on the size of the REU, DeskTop 2.0, Mouse or Joystick driver, printer driver, and any Preference Manager or Pad Color Manager to make the DeskTop look more lively than the standard grey. I have formatted that disk double side.
All the other DA or Apps are superfluous and can run from disk drive B, in my case the C1581.
I did not have a chance to copy the CP-Clock yet.
It's slowly becoming a very nice set up. The chip is really a good addition. If nothing else because it saves from using the original GEOS disk.
