Ah, a toy micro. Don't ever expect better support than this.

Talk to the OEM/ODM that is building the old version. They will have
the contact at the chip manufacturer, or distributor, who can get you
the tools. But if the chip is obsolete, how do you expect to get more?

If you have data sheets, writing an assembler (notably a Forth
assembler) would not be out of the question. It can be more
time efficient then bothering with commercial staff.
On my site below, you can find some examples of reverse engineering assemblers
that could take the task on even if the source of the firmware
were lost.

Then -- as others have mentionned -- do you want to go on with
a part with so little support?

Is the part OTP or MASK?  Do you have lifetime supply?  How would you
get additional parts, even with development tools?  Sound like you
should look for another lines of micro.

I've been tasked to attempt to revise some firmware (I have
the source, assembly code) for an AM8A series processor made
by Alpha Microelectronics in Taiwan.  To data I have yet to
get an email response in regards to obtaining development
tools for this processor.  I understand that the part has
been discontinued but they refuse to respond.  They also
will not allow me access to their download site.

Does anyone I might find an assembler for this part?
Possibly there is an American distributor that I could
contact, but I cannot seem to find one.

Any help would be appreciated.
