The Color Classic web server has been extremely reliable until recently so when the picture disappeared last week I thought it might be related to the CRT. Swapping out the logic board with a replacement brought it back to life, and examining the original logic board revealed the telltale dull, dark areas around the capacitors that signify the aluminum capacitors have leaked their electrolyte onto the circuit board causing connections to fail and the computer to no longer work properly.
For an in-depth guide on how to fix this symptom yourself, check out this page from the 68kMLA Wiki that includes directions and replacement part numbers for those who can confidently perform soldering operations.
But fear not, the Color Classic web server will be back! The original board is currently being repaired by a professional and in the interim is temporarily online with a backup logic board. That board unfortunately has issues of its own, so uptime may suffer somewhat until the repaired board is reinstalled.
Meanwhile, I recently acquired another Color Classic with a Daystar PowerCache 33 accelerator and will be profiling it here soon. Stay tuned!
