I was going through our old equipment and found that we have 6 of these old Leica GPS systems. Do these things have any value in them? Not sure if its worth trying to sell them or just donate them to a school with a surveying program. Any thoughts?
Looks like that is just the receiver. This system has collector, height hook and all. Ready for operation.

Those units would pre-date the GPS week rollover, so whether or not their firmware was updated would be a key. Useless without the firmware upgrade, may have some value as static collectors if updated.
They are dual frequency GPS only recievers. When I used them as RTK units back in the late '90s they worked okay, but were heavy by today's standards and fragile. Too many of the critical components are in the reciever head.
Probably the highest and best use for units like those is as fodder for a trade-in deal.
I agree that static collection is the only real use for them. I fired a few of them up and checked the firmware. 2 were updated in 1998 and another in 1999. Surely by then the rollover problem was accounted for. I checked the current date in one of them and it was right. I assume that proves it, but not sure. Guess I'll just have to set one up and collect and see what I end up with.
299's OK, 399's better and 9500's best, all were possibly called "System 200's"? They were manufactured in that chronological order too. Unless you have some old post processing software, the 299's are probably a paperweight, current Leica software (LGO) will not import that old data.
I did a lot of work with both 299's and 399's, more so with the 399's, they served me well from 1996-2001. I actually did a lot of RTK with those 399's too, not as convenient as modern gear AND they could get a bum "fixed" solution from time to time, but they were as good or better than anything else at the time. I think the Trimble 4400's were the direct Trimble competitor in 1996 when I bought my 399's (or at least that is what the Trimble dealer was trying to sell me when I went shopping in 1996), so that is the era of equipment you need to be thinking about when forming an opinion of these units.
If your "complete" units have height hooks, posts, tribrachs, quick release adapter on antenna base, etc., all that stuff is the same part number as you would get today from Leica for a tripod setup, several 100's of dollars of good stuff even if the units are toast. Some of the cables were still in use on the 1200's too, power cable, antenna cable, etc. You might find the parts worth more than the whole if you are still a Leica shop.

GPS week rolled over in August 1999. So maybe.

Here is a software for transfomation of Wild System 200 into RINEX called "TEQC".
" Leica DS Format:
Teqc can read the Leica 200/300 DS fileset format, used by the earlier Leica receivers, e.g. CR233, CR244, SR299, SR299E, SP299P, SR260, SR261, SR399, SR9500. The files with the suffixes .cmp, .dat, .eph, .int, .met, .obs, and .pnt will be used. The files with the other suffixes (e.g., .chn, .alm, .atf, and .at1) are currently ignored..."

And here ist the GUI for TEQC:
