Basic ROM for HP Portable Plus

[Martin Hepperle]

A few months ago I burned me an EPROM with TurboPascal 3.00 configured for the Portable Plus.
I could make this image available too.
I used Turbo Pascal for writing a small HP-IL and a HP 110 screen access library for reading the 3468 voltmeter and the 3241 Data Acquisition box.

I tried to bring Turbo-C 1.5 down in size for a modified 128 KB EPROM, but the files are still a bit too large (even with compressed executables and compacted header files with spaces, tabs minimized and comments removed). I probably habe to spread it over two individual EPROMS, which I tried to avoid. All later C compilers seem to be too large.
