Hi all,
I recently aquired a defective bppc 603e from amibay. It is unknown to the previous owner what was wrong with the card, but clearly was worked on with a heatgun, as the xtal sockets and fan have burn marks.
The PPC die was damaged too and some of the qfp pins are missing, but I believe they are not connected to anything. There was a short to 3.3 ground and 5V to ground. That pretty much sums up the state of the card.
I worked on it. it now shows no signs of shorts. It still is missing the PPC, thats on its way.
I was confident enough the put the BPPC in my a1200 (1d4 with timing fixes). All I am getting is a black screen. The miggy does respond to ctrl Amiga Amiga. Caps led responds too.
I am using an A600PSU at the moment. Thas seems to hold up the voltage @ a steady 5V, the fan works too.
CLPDS get hot, really hot after about 30 to 50 seconds after power on. The card was configured for a 060, but I reconfigured it to hold an 040@33mhz. Jumpers and xtal 66Mhz.
I used the know keys, like a, s, 2, esc, mousebuttons etc.. but that doesn't make any change.
1: can the a600 psu power the BPPC? Or should I use a beefy ATX psu?
2: Is it possible that the ROM needs reflashing, or should the a1200 boot anyway?
3: Should I wait untill PPC is mounted?
4: I aquired some xtals, like these https://www.budgetronics.eu/nl/quar...tz-kristal-oscillator-60-mhz/a-12365-10000153. But there is no info on voltage or type.
5: Will the BPPC start without RAM? And is it picky about this 60 or 70ns, voltage??
Any help is appriciated!
