Emax

Thanks, I have a rack unit as well.  I remember replacing the backlight, it does look tight in there!
 
I look forward to your success!

Hi Ed,

I will definitely post some photos once I have a permanent installation I am happy with.

On the rack unit, there is not enough clearance for velcro. I had a very intricately cut pice of perfboard that I planned to use for mounting, but misjudged the actual thickness of the stock display due to the connector pins. I had to scarp the pefboard and mount directly to the PCB.

I might look into fitting some screw mounts to the PCB with epoxy. Again, will require some research on my part. I have to look at the board again for placement and search for a PCB friendly epoxy.

I will keep you updated.

One, so far, I am keeping virgin. The other, I have added SCSI to and will be making additional modifications such as the external "Plus" SCSI port.

Works really well and no more concern about backlights. It exhibits very small flickering during some navigation operations, but, I am very pleased with the mod.

I just soldered wires to it to make sure it would work, but they are a bit too heavy a gauge and the fit is tight. You also have to work out a mounting solution. I just matched up one of the mounting holes with a blank space in the front panel board and drilled a hole. I will be adding a proper header and ribbon connection as soon as I have all of the parts.

I have socketed the dual (stereo) output chip already and tried an alternate I had on hand. I will be researching and order some other chips to try out. Very interesting and fun. I have learned a lot about the unit digging around in its guts the last couple of weeks.
