Hi.
the -06 mainboard I wanted to change the video daughterboard, after that I could not get the computer to boot. I unplugged the Rememorizer, and then put in the original roms and then the computer worked again, I even could load games from tape without any problems.
Then I unplugged the 2 roms and tried the rememozier again, still the same tried the rememorizer on another board where it work as it should boot up in cp/m on the vga output.
So the rememorizer work, but what is wrong here ? Any clue.
When I try with the -06 mainboard, I get black screen and humming sound as expected, but for much longer time than normal, and the vga output shows a yellow flashing cursor.
To me it looks like the Computer do not see the remeorizer at all ?
Suddenly dont work on one mainboard but work at another ?

Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer in Somerset later in the year
Not as many MTXs as Dave!

Did you have to change the RAM/rom jumpers when you tried it on the other MTX ?
Something you could try ejecting and re-inserting the SD card fixed my re-memorizor when it failed to boot when I hadn't used it for a while.

Martin, nothing was changed, just took it from one MTX to another. Its quite weird, like something was blown.
Maybe an IC controlling the exp. port ? So it dont see any add-on boards?

I think what Martin is getting at, is are the two MTX computers the same RAM configuration?
Is the PAL/replacement GAL correct?
With regards to the video daughter board, I don't recall any critical circuits going to it. The only thing I can think of, is it does use the +12V supply. If this is shorting to ground, then the video DRAM chips will not work, plus it will affect anything else fed from the +12V line.
