Hey, at the school that I work at we have a Fat Frog that has for some time now been out of operation. Had a play around with it today and here's what it does, each time I plug it in a different set of LEDs illuminate (sometimes flicker). By angling the power lead and holding it like that I can get the LCD screens to illuminate but nothing appears on them. The floppy drive LED illuminates most times as well, whether there is a disc in or not. Connected to a monitor there is no output, the LEDs on the connected keyboard do flash as would be expected when the frog is plugged in though. I don't know how but today I managed to get it to reach the BIOS level, where it stopped at "Checking for upgrade disk" on the onboard LCD and external monitor. Some weirdness that I found with that was sometimes when I put the floppy in on that screen or turned it on with a floppy in (containing the upgrade files) it would restart a few times before getting stuck at the same screen.
I have cleaned out any dust from inside and checked the battery voltage and checked all connections internally... all seems fine.
Although this has been heavily used, it's been looked after and I can't think of many reasons for it breaking like this.
Any pointers or ideas are greatly appreciated.
Thanks, Ollie.
