Yes, I'm not sure what I was thinking when I typed that. I filled
(14x) of the max (16x) EPROM sockets with 27c256 EPROMs for a total of
448KB (458,752 bytes).
Maybe some day a copy of that will turn up somewhere. I'm curious
what the magic .init file does that appears to be necessary to include
in the ROM image, and also what the file annotations mean in the romrc
file.
Maybe 'a' mean executable application that needs to be fixed up by
ld_mod to execute in place, 'D' means non-executable data file, 's'
means executable script file with no fix-ups necessary. Not sure what
'on' would mean.
Here's the romrc file from the ROM tools disk example2:
/Rtools/example2/.init
/Rtools/example1/time_of_day a
/Rtools/example1/set_font a
/Rtools/example1/7x10 D
/Rtools/example1/status a
/Rtools/example2/Autost s
/Rtools/example2/set_win on
I used (15x) 27C256 EPROMs and built the ROM image to start at 1MB
Can you hav an odd number of ROMs? I's aseemed that since they went in
pairs (the ROMs are 8 bit wide, the Integral's data bus is of course 16
bits) you alwauys had to fit Hi_n and Lo_n together.
It would still be nice to find a copy of
"HP82970A EPROM/ROM Software
Development Tools Users Guide" for reference.
I know I don;t have it, alas.
