Hello,
I'm using a really, really old version of C51; specifically, version 4.10, old enough that it's branded with the Franklin name. I'm maintaining a couple of existing products, and although I have the compiler, linker, etc., I don't have the RTX-Tiny libraries.
I've purchased the latest Kiel product, including the RTX-Tiny subsystem, but the RTOS interface (and in fact it appears the entire library structure) has changed, and cannot be used with the older version of the compiler that is still in use on these older products.
The Franklin and Kiel companies parted ways quite some time ago, apparently in a large cloud of dust. Although there is still a Franklin software site (fsinc.com), all the email links on it bounce, and the phone number listed has been disconnected.
I certainly would like to acquire these older RTX-Tiny libraries. Does anyone have an idea where I might track them down? I don't want to encourage software piracy in any form, so I'd be willing to pay a sensible license fee (remember, this stuff is >>10 years old...) to upgrade my existing compiler tool chain, if it seems appropriate.
Thanks for any help you can give!
