Re: STFM RAM Capacitor value? Suggestions?

In first post, second image. In the top left corner, the reset switch is missing. Is it more stuff missing on the board?

Re: STFM RAM Capacitor value? Suggestions?

0,1µF capacitor. Or 100nF depending on how you write it. But it have worked before?

Probably is one or more of the ram chips faulty. Do you have a test/diagnostic cartridge to boot with?

Re: Compo software dual tos 1.62 / 2.06 rom images - where to find?

Use cartman tool and split the files in high and low. Both low on the same chip and both high on the other. Put lo/hi from 2.06 on the same adress (0000) on the two chips. Same for 1.62 but on address 2000 and onwards. As techie_alison describe in the link you gave.

Re: Replacement power supply

An SR98 PSU common in STfm is rated for 3A on the 5V rail and 0,9A on the 12V rail. USB 1/2 standard is 0,5A on one USB connector if I remember correctly. But I think UltraSatan needs 1A to run. And you got 3A to use so you got plenty to use. You can connect a USB directly on the screw terminals. If...

Thanks, now i need to check the Ohms value with my ohmmeter (when you're a bit color blind it's hard to see) :lol:


It should be 47 Ohm according to the schematics.

2x32 pins.
