What's an acceptable/fair price for a working Robotron ROM set? I'm building up a robotron and I have a chance at a set but the price seems high for me (especially since it's untested).

I just bought a couple of used boards from ebay for around 20 apiece (i think)
in my opinion 15-20 is plenty high.
for 1 they probably have old roms so you'll have some expense in getting new ones burned if you want solid patched blue roms.
and 2, the ribbon cable is probably shot even if it works. so that's an expense in ordering one and a tedious job to replace.
you know what I find unusual. the robotron manual states that the old orange roms were replaced with blue for production machines.
but every loose rom board I've ever found has orange roms. Just what machines actually got original blue roms. must not be as common as the william's manual states.
I have 4 sets of orange roms now. I'd be curious to know if those original roms could be reprogrammed on a machine. that might be a nice thing to do with otherwise junk parts....
i also noticed something about rom sets that is contrary to what i read online.
they state that the yellow/orange/red (whatever color that is) will boot to a default difficulty of 3. which is true.
but my patched blue romset also boots to difficulty 3 after you do a factory reset.
What's the truth on the blue vs orange difficulty default?
Well, it looks like I am glad I came here. I'll out myself and say I was looking at paying $125 for a set of Robotron ROM chips. I don't think that will be happening now.
This was the ebay auction he stopped that he'd be selling me the chips from:

Two questions, is that even a complete set of Robotron Chips? He's missing chip 4-B and 7-B, correct? Also any william's experts out there able to identify the other williams' chips?
My last question would be, what's the difference between these robotron chips and the "blue" chips I keep seeing mentioned?

I thought blue was also supposed to be 5.....Perhaps the Jrok board should really be set to 3 instead of 5!
What does twin galaxies say the difficulty should be set at for marathoning??
C.
just checked the blues i just put in and they are set to 5 and not 3
