If you do get the site working, or contact the site owners, this one might also be worth getting (£7.5 rather than £0, but also fails to check out):

Covers FX-85/185, FX-80/100, RX-80/100, MX-80/100.
(Principles of Operation, Wiring data, Repair Analysis Procedures, Parts Lists, Repairs and Adjustments, Final Actions, General)

This book on pages 11-12 has a brief overview of the differences between the MX-80 versions (suggesting mostly firmware differences, and with the Type III including the previously optional Graftrax 80 support):

This VCFED thread also discusses the ROMs (and the 5152 printer):

The Graftrax 80 installation manual also has a component layout diagram on page 4:

Here is the Epson MX-80 III FT - Sams ComputerFacts:

Here is the IBM 5152-002 - Sams ComputerFacts:

If you do manage to get hold of either of those Epson PDFs on, I'd be very keen as well.
