Hi,

I don't know if you can help me with a mistake I made in a Philips VG-8020. Testing the CASDUINO, he hanged himself, and no longer restart. Video signal arrives and the LED of CAPS turns Green but does not charge the BASIC.

what can I do?
This is my first MSX (I've always had Amstrad)
Thank you very much

Is it a VG-8020/00 or /20? They're quite different inside.

It depends on what you call "testing". Please describe what you did with this cartridge. Maybe it will give us some clues on what could have happened...

Casduino is not a cartridge, it is a cassette player emulator. And I wonder if you can break a computer with wrong voltage on cassette input so it wouldn't finish booting... i hope there's something easily fixable btw

Oops, mixed that device with something else. Hmmm, I can hardly imagine how loading from a simulated cassette recorder could damage the MSX. Maybe plugging it into an RGB port could do something bad. But even if supplying high voltage to the cassette input/output circuit you can't possibly fry the entire MSX.

I don't have 8020/20 here at the moment (it is still in Ukraine meanwhile) so i can't open it a have a look, but this is a weird beast. I bought one for mere 20 EUR few years ago as non-working unit, and it was only the fuse - i replaced it and it started booting. Then i tried to connect RGB monitor to it's DIN8 video output (which wasn't an RGB output as i learnt after that) and the fuse again went bad. Though everything was fine after i replaced fuse once more, and the monitor didn't get damaged as well so i think i was lucky twice as much Smile I like the overall look-n-feel of this computer though, and keyboard is not bad too.

Let's just hope the S3527 on that machine (if it's a /20) isn't fried.

Tonight, when I have a little while, after sleeping the kids, I look at it... thank you!!

I'll look at the fuse stuff!!
