http://mess.slor.net/sys80.zip contains a collection of system-80 ROMs organized for MESS.
I am not sure who collected these but if you have more and post them to one of the
alt.binaries.emulators lists asking someone to add them to the MESS sys80.zip collection it will likely be done
Typically there is often a self-designated "librarian" of sorts for each platform that assigns a TOSEC name to each file. Once that's assigned there is a hash that is associated with the "official name". Ira may have done some TOSEC naming for TRS-80 Model 1/3. If you have a ROM and you want to name it officially he might take it with your name recommendation.
At least then if you have several ROMs, even with different names, you can run a utility on them to "correct" the names and eliminate any duplicates. TOSEC has/had a free program called TIM that would let you do this. I can't remember clearly but I think they might have had a way to generate .dat indexes which can be used with CLRMAME and other MAME .dat tools.
Another non-TOSEC renamer and ROM organizer is GoodTools.

http://mamedev.emulab.it/clrmamepro/download.htmSorry, but I'm unaware of any online "TRS-80" collections of code other than the
which is likely the older collection version stripped off the
trs-80.com site. (And also there are some torrent collections.)
p.s. here are some ROM links but none EACA/SYSTEM-80 AFAIK.
I guess a lesson here is that if you make a MESS EACA/SYSTEM-80 emulator,
no matter how crummy it is, there are MESS folks who will archive your ROMs for you. ;)
