Are mbed LPC1768 now obsolete with Mbed OS Keil Cloud

I have a load of old mbed lpc1768 which I use for training however none are working
with this new Keil Cloud system. They used to work fine on the old mbed online compiler.

Do I need to throw them in the bin and get an upgrade, if so what would be the natural upgrade for the LPC1768 to work on Keil Cloud system ?

Mbed LPC1768 is working just fine in Mbed CE! I use one regularly for testing. It’s even possible to debug code on them using OpenOCD!

Also I believe that LPC1768 does have an experimental interface firmware that allows it to work with newer Mbed tools, have you tried that?
