To convert 8 bit binary to BCD (10 bits, I assume), try using a few 74185
chips.  I'm not sure of the exact configurations, but the data sheet shows
how to cascade them to get wider convertors.  You'll probably need about
4 or 5 to get the width you need, but since they are only 16 pin DIPs, and
they need not be 'burned', I think the are a better solution that EPROM.

I think it is the National Semiconductor sheet that has all the
configurations for various widths; the TI sheet I have only shows the 6
bit configuration.  Also, for those who are interested, the '184 does
the reverse conversion (BCD to Binary).

Cheers, and happy hacking.
