I've bought another Schneider Euro PC. This one has the power supply included+Schneider Joystick and mouse. The computer has a game card installed, which is pretty useless though: it simply has two joystick ports.
The outer appearance was very promising: virtually no yellowing on the computer or the keyboard.
Compare this to my other Euro PC, which I discussed here. In this picture, it's the one below.
|The case yellowing is not as visible from the photo, but it's there.|
However, a look at the inside revealed a sad truth: the battery has died and corroded some parts of the PCB.
|Does not look too bad? Look at the surface mounted chip peeping at the bottom right.|
I of course removed the battery. Also, did some reading on the net, and it appears that the PCB corrosion is a many-splendored thing. It would be best to take a board with this damage to a professional...
Well, I simply lathered the PCB with WD40 (Good enough for your dad, good enough for you) and started cleaning it with Q-tips and scratching between pins with a paper knife. Edit: I've since learned you're NOT supposed to use WD40 for cleaning PCBs.
I'd like to say this heroic activity had some positive outcome. But... no, on power-up the machine just lets out one horrendous wailing beep, and that's it.
Connecting to Commodore 1084S
It's not all sadness and gloom, though. At least I got a proper power supply for my older Schneider Euro PC, which has been proven to work. Also, as I now have a monitor with TTL RGB support I could easily connect my Euro PC to it. I could have arranged both by other means, but it would have been more trouble.
|Now what to do? The Euro PC has the only working PC floppy drive in the house.|
|My monitor has the DIN variant of the TTL RGB, other monitors may have the 9-pin D SUB. Note the absence of SCART type connector.|
In the end, contrary to all past experiences, my cable worked on the first go.
The information is not too hard to find out but here are the pinouts anyway:
Euro PC monitor pinout at the back of the computer:
8 Horizontal Sync
9 Vertical Sync
Commodore 1084S TTL RGB (DIN 45326) at the back of the monitor:
1 Status comp
7 Horizontal Sync /CS
8 Vertical Sync
I connected everything directly to their corresponding pins. I connected the two grounds from the Euro PC to the one ground pin of the monitor. The "status comp" I connected to the "Monovideo".
