Color Classic Needs Serious Help
we are looking for v2.0 install images...
if you have them please contact someone (me)
if you have them please contact someone (me)
I picked up a Color Classic this morning. Cosmetics are good, a little yellowed/dirty. Came with and external SCSI CD and a carrying case for the whole thing. Pulled the board and it had a Toasted Maxell battery. Battery gunk everywhere...
Cleaned it up with isopropyl for now and assessed the damage. So far here's what I've found:
No trace of any of these components is left:
Battery Clip - Gone
C6 - Gone, pad damage
Y1 - Gone
S1 - Gone
These IC's have damage:
U11 - LS245 Data Buffer/Driver Half of the legs on each side are gone, pads gone.
U7 - 341S0417 / 0C25TTLDZ9320 - Made by Moto- Apple specific? - damaged legs, pads gone
U8 - Can't tell what this is - Several damaged legs
The board itself around these is in good shape and I think it can probably be repaired. It'll just have a lot of blue kynar wires on it... appears to be just pad damage.
It needs a re-cap as well. C9, C10 are leaking.
So I'll need to determine what the best course of action is with this--
Where can I find replacements for U8, U7, U11-- U11 is common I'd guess, but U7 and U8?
Have to find the values for C6, Y1, and S1
Any recommendations on sourcing these? Or would I be better off looking for a donor board/replacement board?
Not sure how to post pics here, If someone can tell me, I'll upload some to Photobucket.
Thanks,

Thanks,
awesome i have every version but that one..
1, 1.01, 2.5, 3, 4, + 5 but not 2.0!

That's alot of damage and enough parts another board would be easier. I'll look and see if I have a spare.
Or just go for a board upgrade at this point.
np.. no rush
its quite possible they didnt update the banks.. we will soon find out;)
OK Thanks-- I think this board is similar to the LC II-- Wonder if I can get the parts from one of those...
its now been posted on the download boards 
way cool - thanks devils_advisor

U7 341s0417... I think that is the CUDA chip.
well.. it seems that we are going to need the original soundbank cds Because i tried 2.5's and it didnt work
Anyone know if you can swap CUDA chips from one board to another? Or are they board specific?
If they are board specific, then I guess this CC board is junk (or parts)

I picked up an LC550 board from a working machine. No sense trying to fix the old one I guess.
It'll run better with this one anyway.

im out of state right now. i might be back home in 2 weeks

devils_advisor u are dead to me
u are sleepin with the fishes mate
Please, calm down. We will find it sooner or later. There is no need to blame/bull him.
I am not sure if I can outlive another Supernova explosion.
Knez went to the dessert and he came back with lots of gifts...
as a Messiah called Knezzen. Maybe when the devil advisor come back he would came with the devil himself... On inedit OS9 software.

yes, and now technically you have a Color Classic II.
The machine is running now, but the hard drive is junk. (No surprise)
Any chance that I could use a Hitachi 73GB Ultra SCSI drive with a 68 to 50 pin adapter and just create a 2GB partition?
I have 6 of these drives...

devils advisor had not uploaded the other 2 discs on purpose..having thought that it would work with the soundbank + orkester cds that came with reason 2.5
i tried this before and failed.. I am trying again to see if i can get reason v2.0 to open
**UPDATE**
success! reason v2.0 does in fact open with the reason 2.5 orkester + soundbank cds
im not sure if i only tried mounting them last time via toast
but this time, and what i can confirm as working, is to actually have the physical cd in the drive
during the install process, i checked custom install, and chose only to install the program files (leaving unchecked orkester + soundbank)
when i tried to isntall with these boxes checked the cds failed the check and it would not allow me to continue.. perhaps this is why
i thought this didnt work last time.. but if u install just the program files from the program disc.. and then run the app
it will prompt twice, once for each of the cds, for the cds to be inserted physically into the actual drive.. orkester + soundbank, and when i inserted the version 2.5 copy of these discs it authorized + proceeded to open reason v2.0!
success!
reason v1.0 + 1.01 i think are a breeze because they recognize the toast mounted cd image when it asks for the cd
2.0 apparently does not recognize the toast mounts at all and requires you to use real physically burned discs
u have to select custom install to get it installed tho, as the installer app doesnt recognize the 2.5 sound bank cds
with this newly confirmed information im hoping we can repost reason the v2.0 program disc back to the downloads section
but including installation notes to explain that it
can be installed with the 2.5 snd bank discs but
A) the discs must be burned to REAL CDS
B) u must deselect the snd bank cds during the installer
this wouldnt be a problem if we had copies of the actual 2.0 sound bank + orkester discs! which im still hoping someone will volunteer some day

Try it. Some support SE some dont.
It's worth a shot I guess. They're Hitachi Travelstar 10K drives out of a Dell Server
Techknight, What do you mean by SE ? Just a Mac SE, SE/30?
Techknight, What do you mean by SE ? Just a Mac SE, SE/30?
SE as in single-ended bus operations. 50-pin SCSI is SE. 68 and 80 is LVD and rare cases HVD.
OK. Yeah these are LVD/SE with an 80 pin, not 68 pin connector. I thought they were 68.
I bought an adapter that does 80 to 68 and 50 pin. I'll post the results if it works or not.
I guess I should try 7.5.5 and see how big of a partition I can create.
I read that 7.5.5 supports up to 2TB, but my guess is I'll end up with either 2GB or 4GB

If the adapter isnt terminated youll need a terminator.
It's not terminated-- Do you know if one of those pass through active terminators will work ?

Wow. This thing is giving me a fight. Thought I was going to get this working and was almost there.
Analog board now has a problem. it popped the fuse. RP1 is burnt. Totally bummed.
Anyone here repair analog boards?

I've been checking components and so far the only thing bad is the RP1-- It says it's 10 ohms, but It looks more like a thermistor...
So it turns out QP7 , and IRFBC40 power MOSFET is bad too. Totally shorted. So I have to replace that and RP1
RP1 is a 10ohm NTC thermistor, but I have no idea of it's amperage rating and can't find anything on it.
If the main fuse on the analog board is 3.15A, is it safe to say that thermistor is rated at 3A?

if the main switching fet is shorted, you need to find out why.
make sure your horizontal output transistor isnt shorted, check secondary diodes for shorts.
if you lost the main switching fet, you will need to replace a handful of components with it, such as the controller IC.

Thanks, I'll check the horizontal output transistor.
So far all the seconday diodes are OK, caps, resistors, etc... as well. I've been slowly working my through the board
I figured if that FET went, it took the controller IC with it, so I ordered a couple of those, along with the FET.
The IRFBC40 is rated at 6.2A, but the only thing I can't figure out is what that Termistor might be rated at.
There's a bunch of choices for NTC 10 - 3A, 5A, 6A...

It's Alive-- Been running for about an hour now.
Turns out the only problem was that IRFBC40 FET and the Thermistor. I replaced the TDA4605-2 controller IC as a precaution.
Now, time to recap the LC550 board....
