You will need some kind of EPROM programmer. I don't know of any that
work with Linux, but I haven't looked. A list of EPROM programmers is
available on our web site at http://www.link-comm.com/promprog.htm.

I think that Angel really wanted to write to the EEPROM that many of
the 68HC11 chips have. Thought there is an EPROM version of the chip,
I think that it is the 68HC711. And I don't know if Linux can D/L to
the chip but I think it should be possible. Check out the Miniboard,
Handy board or the 6.270 boards. I'm prettysure there was a simple
downloader that had the source so it could be compiled under Linux. If
I come across it I'll post the info here.

The HC711 is one time programmable (OTP) ROM . The XC68HC711 is EPROM
(erraseable), it's in a windowed cerramic package, very expensive and hard
to get.
You can write to both the ROM and EEPROM using the internal bootstrap
loader. It requires a very simple connection to a serial port (MAX-232) and
a couple of bits of code. Check out Motorola Application Note AN1010, it
should be on their web site.
I use this method to load external FLASH and internal EEPROM on the HC11A1
and HC11F1 versions. I having a PCB jumper in the product to enable
bootstrap mode for initialisation. I use a customised version of the Basic
program and boot loader.
Motorola produced a programmer board that works in this way. Last time I
looked it was quite expensive. You could make your own a couple of hours.
The version of their loader program (GLOADE9), that I have will only
communicate when run on an old 286 PC. The timing needs fixing up for a
faster PC. The source code is in Basic, so it should be easy.
