several repairs spectrum and timex
« dnia: 2023.08.12, 14:07:38 »
This week I am repairing one toastrack Well... after I tried that on timex...
keys don't work -> membranes are avaiable for the spectrum... not for the timex, but the timex are easily servicible... ;) watch my youtube channel
sorry in portuguese.

for the toast rgb works fine, though I had to get an modern ULA CPLD nothing comes out of the ic original.
TEA 2000 the culprit? I took it out also bad... the thing that burned this toast was the TEA? all the transistors between the tea and the composite are ok. weird...

I usually on my repairs I take everything bad out... this old stuff  is good for self induced cathastrophic malfunctions... now waiting for an old TEA and for the membrane ;)

On my repairs, what I find stressfull is that there is no ula for the timex, and they are related... will try to make one eventually this year or next year...  no one gives me one working to me, there was something float around and then disappeared.... :D
