I think that the last time I talked with Mark (?) that he was sort of emphatic that there were no parts for the original series, and implied that the LR models were in so many different types (same designation, vastly different boards inside) that it would be a lucky chance to get something that worked.
I asked if there were any old boards that people had sent in for fixing or units that could be canabalized to get one working system and he wasn't hopeful, in fact again sort of emphatic that the type of stations were a thing of the past, no parts, no repair.
I have a bunch of old stations from the last decade of eBaying collecting and am in the same boat. I have a sometimes works/sometimes not LR station I'd like to get going again (I have one with poor wind direction function) and three old non-LR stations, along with about a half dozen displays for the Non LR. The display for Oracles is the same, with a different receivers AND a different EPROM on board. Years ago I bought a new EPROM for a non-LR station and put it in, and replaced the long antenna receiver with the little stub antenna receiver and it is still working. But what's on the EPROM is anyone's guess and the availability of the black box receiver is rapidly waning; I've not seen on on eBay in awhile.
Too bad since these were good systems, and the display was relatively unique, especially in this day and age of everything LCD.
