Its been asked already some time ago if Turbo can/will support JavaCard or any other Java-based programming. So, I wonder if there are any progress or updates in such area?

By the way, there is a very compact VM implementation for Atmel AVR ATmega8 CPU. Maybe it is possible to port it to Turbo.

Well, there seems to be almost none interest in Java(Card) on Turbo. But the vm you posted is interesting and should be easy to port. Unfortunatelly the code will be very limited. It could be linked to vm and stored in FLASH (not eeprom as in this vm) but the real issue is java vs. RAM usage.

What is the RAM and FLASH memory available on Turbo, Turbo-Lite and Turbo SIM?

I guess if you'll get Java support (J2ME or JavaCard for custom applets) there will be demend. I'm seeing number of requests how custom SIM applets could be deployed on the real phones. In any rate there are better tool for Java/JavaCard development (e.g. IBM's JCOP).

About 35KB FLASH, 1.5KB RAM for user apps. All devices are the same.

Yes, we know because these developers usually come to us and port they apps to Turbo SIM Smile They want to deploy applications, not applets.

Mmm, better than what? If you mean Turbo then no way, from technology perspective (what you can do with what resources), development perspective (ease of development, openness, debugging), ability to use the application in real life (what is it good for to have JC app you cannot deploy/use) and overall cost Turbo is unbeatable.

But that doesn't mean we will not take a look at the vm posted in this thread.
