Boy, I sure stuck my foot in my mouth this time.

First of all, I meant to send my previous letter to Scott Guthery,
not to the whole list.  D'oh!  I forgot that the Reply-To was not
the same as the From.  I apologize for sending to the list what
could certainly be construed as a commercial email.

Second, now that the damage is done, I'd like to emphasize that my
letter was *only* in response to his comment:

It was *not* intended to suggest that the Forte card is at all a
solution for the subject of this letter (and thread), a smart card
with a replaceable OS.  It most certainly is *not* that!

[EMAIL PROTECTED] asked a bunch of stuff, some of which I'll try to
answer below, but again a disclaimer: I am *not* working on the Forte
project myself, and am not authorized to speak for SSP-Litronic on
this subject beyond what's in the web site.  That said, I'll try to
make a few comments.

No!  The ROM is, of course, read-only.  The OS can be patched via
the EEPROM.

Of course, but I highly doubt it's available publicly.  Much of
this is probably classified.

Don't know, but I suspect yes and yes.

Some of this stuff I *know* is classified (and I don't mean company
proprietary).

If anyone wants more info I will have to refer them to someone else
here, either technical or sales.  Email me if you are interested.
I must warn you though that as a small company with very limited
resources, we're not interested in supporting the hobbyist (yet).
We're looking for customers who want thousands to millions of these.
