Just acquired an eBay T102 with an OPTROM that was not listed in the sale description - surprised to see it there when I was replacing the battery. When called it sets up as TFDC99 in the menu. Trying to run that generates a FF error at 10. It is housed in an EME wrap around PCB and looks like it uses a regular EPROM. It could be a commercial piece of software or someones project, there are no labels on the module - does not appear it ever had any.
A quick search of the Archive and Google did not throw anything up, just wondering if anyone might be able to shed any light on what it was/is/could be? When I get time I can dump the ROM see if it has any useful copyright text. Thanks!!
