I've just found a USB-FLASH driver for my recently acquired J820 and I'm very pleased! Really thought I wouldn't.
The driver is the USBclik jobby for the NEC 900, and I found the info on this site.
It brings the machine 10 years forward, and makes modern laptop users jealous!
Couldn't not join after that....
I'm hoping to find some C++ compilation info in the dev section, as I've had no success so far, either with the eVC3 or eVC4.
I use the machine as a "portable math workstaion", trying to get a decent HP49 setup running
(Emu48
). I've also got the Java-like Ewe running on it, it looks promising.
Always glad to talk about mobile development.
Many thanks to this sites originators!
