For those of us who are unfamiliar with T87, is there some (short)
example document and the ASCII of the text contained?

The drivers_info_t87 file supplied with it states that the sources for the
printer drivers were not included on the disk for lack of space but were
available on request from the author Fred Toussi. I'm not in contact with
him now, but if anyone did go to the trouble of getting these from him, it
might possibly help I suppose.
There is some information at the end of the above file:
STRUCTURE OF PRINTER DRIVERS
Each printer driver file consists of tables of numbers and strings and a
small amount of machine code. The supplied files vary in size. The
Assembly Language source code for the driver files is available separately
from Software87. Some of the source code files are for more than one
printer driver. Modifying the driver files requires the use of an
assembler to re-assemble the modified source file. Modification can be
very simple, as in the case of changing a number representing the pitch of
a daisywheel, or more complex when a printer with a completely different
standard is aimed at. With many Epson compatible dot-matrix printers, the
width tables for proportionally spaced characters are different from those
of the Epson printers for which there is a driver. This means that when
proportional spacing is used within a line, that line may not justify
correctly. The width tables within the printer driver should be modified
for correct justification.
The source listings are in the form of _T91 or _T87 documents. Extensive
comments on the structure of the printer driver files can be found in the
LX800 file. Once modifications have been made, driver files must be
|Export|ed using the |Ascii| command to make them readable by assemblers.
The SINCLAIR Macro Assembler or Assembler (written by GST) can be used for
assembling the printer drivers. The Macro Assembler can be purchased from
QUANTA.
I have a working Text 87 (thanks to Marcel for the patch program) so could
export the data to help anyone prepared to look into this if we can find
these sources.
As it is, I’ll privately send you some Text87 files to experiment with
along with exported ascii text to compare. I’ve not looked at it myself,
but I suspect that with all the options such as proportional spacing etc
etc Text 87 has to handle it might be a very complex file format.
