I'll try the trick mentioned above, and if that fails then I'll try asking at HCWP or something...

I think this was discussed before here somewhere. Something is different with the internals of the cables if i remember correctly. Not sure of the specifics.

well, the only difference there can be internally is changed wire positions inside. otherwise, there's not much to the cables, except the wire itself.

I've heard something about wires being crossed or switched or something, but I don't remember where it was from so it might not be a reliable source... :P

But it's looking more and more like that's the case.

I think I have heard of this before. So I'll need to keep this in mind on the Prizm's 84+ emulator project. To do so the emu would first have to test which cable type is connected then set whether an inverse of data needs to be done or not.

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)

Unlike Casio, TI doesn't use the standard "audio" plug.

No, I can't see anything other than the black part being a bit thicker, but I don't understand how that would affect anything...

Try to plug in a Casio cable in a TI calc? I don't have any Casio cables or calcs.

Any standard audio plug is the same as the Casio plugs.

The problem is that you have to be very carefull when plugging it, or you'll get contact issues.


For example, the calculator does temporary freeze (cursor and keys) if it's not plugged correctly.

Wait - the Casio I/O cable is different from the TI I/O cable? Well that stinks. I just cut a Casio cable in half to use with my Arduino - does this mean it's not gonna work? I did find the expected red and white wires and the coil of ground wires, but are they wired differently beyond that?

Also, I do know that Casio link cables, since they are angled, do not fit in 84+ calculators (the indent around the port is too tall). That might be your problem as well.

Hmm... When using my audio 2.5 mm plug (headphones) with my 84+SE, the issue of one sound channel disappearing is frequent. I have to move the plug a bit to make it work. The OS always freezes when headphones are plugged in, but I assume it would be different if a calc is plugged in instead.

Oh...So, because the recessed ring is further down on the plug, does that mean it's likely to fall out and/or the contacts may not match up?
