After a short Google websearch for Dolphin 7200 Terminal, I found the technical specifications for the Dolphin. It says there that the terminal is basically a DOS PC, possibly either an embedded 286 or 386 CPU, judging from the available memory size. According to this, it's the AMD 386ELAN chipset. So you could go and try to run a DOS Perl build on that thing, as they claim that both MS C++ and Borland C++ can compile for that thing (16-bit programs is my guess). But as the memory limits are rather hard, my guess is you will soon face some dire problems, both with the disk size (2MB) and available memory (2MB).

From the data sheets it seems to me like the Dolphin is more a data collection tool and no data processing tool, so you might be better off to write the data collection stuff in C, and deliver it to a central server for further processing. A server that does the processing in Perl of course. If you really really really want to run some vestige of Perl on that machine, you might also want to consider Perl4, which maybe requires less memory on disk and RAM, but which has no module support.
