Not that I know of. The joystick/mouse port inputs and outputs are handled by three different chips, making such a solution pretty awkward to implement. The keyboard on the other hand is just two...

Yep, most (all?) string functions use a temporary string buffer for their operations, which enables them to be used as primitives. Using their addresses and reading/writing the memory directly...

Yeah, you're trying to assign a string to a pointer, when in fact the pointer needs to be a long number. The result is that the pointer points to the address represented by the first 4 bytes of the...

FAT32 isn't limited to 32GB. Any normal filesystem can be used for cards in the PCMCIA, but FAT32 (via Fat95) is the most useful, and that supposedly has a limit of 2TB (though I haven't tested it to...

Yep, so long as you use the OS it should be doable. Even handling 8 bitplane bitmaps can't be done on an OCS machine using the chipset, so you just need to avoid those commands. Having an RTG card...

The keyboard membrane and connector aren't likely to cause that sort of behaviour, it does sound like it's connected to the reset circuit. I would look at the reset lines and make sure they're giving...

Yeah, WBlit is system friendly indeed, though there's no W-equivalent of BBlit or QBlit, which limits it somewhat. It really comes down to what and how exactly you need to draw the various objects.

All Megadrive gamepads must have an IC. If it doesn't, it will have a large number of transistors and diodes, and that wouldn't be very cost effective. If you mean Mastersystem pads, they're...

Swap pins 5 and 7, or for improved compatibility, connect pin 5 of the pad to pin 7 of the Amiga, and connect pin 7 of the pad to pin 7 of the Amiga through a 1K resistor.

To be honest, any dual rail (i.e., not explicitly single-rail) audio op-amp should do the job once it has the correct pinout. There's a good chance the ones you ordered should do the job just fine.

A logic analyser/probe will (if it can run fast enough) be able to detect any digital signal - clock or data. So it should be able to tell you that your 7MHz clock signals are all running or not.
