Here is an update on the progress. I successfully fitted the new AA084XA03 8.4 inch XVGA display unit and it sits nicely
since the size is a little smaller than the original one. Two original posts were reused and two new ones added.
Since it is also a Mitsubishi unit the backlight did not require any modification.
I had to use VGA connection though as I could not make HDMI to work with the new display controller. I fitted the display controller on the top of the
SSD. Used three posts and threaded holes in the aluminum plate that holds it. The cable between a controller should have been connected
to the VGA connector at the back of the motherboard, something I did not like. So I looked around for a graphic card option that
would have an internal connector. It turns out there is a significant number of the low profile graphic cards where VGA is connected to the card
with a cable. I unscrewed that VGA connector and made it internal to the unit, so no external video cable anymore! The word of caution
here. The card must be low power one, this is one of those cases where lower performance gives better results. I used HIS HD 5450 (ebay, $15 shipped).
I also tried Geforce GT650, which I had, but that one used too much power to work reliably.
I also fitted an additional 12V 5A power supply to the back wall since I suspected a lot of stability issues people saw earlier were caused by
the original power supply not being able to handle the increased power consumption.
I used it to power a display and a CPU 4 pin connector. A relay connected to the original 12V powers it up.
Eventually, I also upgraded CD ROM, I believe any slim drive will do there. Mine required some special power cable so I needed to get one as well.
I also upgraded the panel backlight to the LED. I ordered a cheap kit ($5) out of curiosity and it turned out to be very easy mod as the LED fitted nicely inside
the grove of the original CCFL metal holder. There is some long video on yourtube on how to fit the LED backlight to the particular panel I used.
They overcomplicated things, removed PCBs from the panel, etc... nothing of that sort was needed.
Last mod I am planning is to put a combined USB extender/SD card reader in the floppy bay.
I also want to mention that the oscilloscope application can be run via a remote desktop. You have to exit agscope, connect to the device, and restart abscope.
For me it is a better option than a secondary monitor as I already have a PC monitor at my work bench.
I can nicely see all the traces while the oscilloscope sits on the top shelf without straining my neck too much.
I had some problems making agscope to start on power up with Win10 , placing a shortcut in the startup folder did not do it for me. The solution was to add autologin and to create a task with a trigger on logon. I also reduced the level of notification to avoid windows warnings when trying to run application in the admin mode.
It was a fun project. I see now that agscope application cannot show the model number of my unit, I wonder what goes on there. The developers should have reserved Frankenstein model for those cases
