Dear --- Ω ---,

 

You never reacted to following:

..., where the NanoPEB locks one into stagnation without even being 100% compatible.

Sure that it is the NanoPEB and not the CF7+, which is not 100% compatible with the TI hardware? If so, then please tell me, in which cases do you encounter problems?

 

 

Regards

Sorry for missing your post...

 

The NanoPEB (not CF7 as it has no RS-232) does not work with legacy software like Telco or other communications programs.  I've not kept up-to-date on that aspect, but I believe InsaneMultitasker may have remedied that limitation with his TIMXT.  The NanoPEB does however work with Stuart's Internet browser, so that is a good thing.  

 

Another problem I've experienced (on my second unit) was the intermittent corruption of data on the CF card when writing to it from the TI or copying data from one emulated disk to another.  Some units are flaky.

 

The thing I do not like about the current design is that it locks you into an unexpandable situation.  Maybe the new rumored design will correct that, I don't know.

 

Some people have had success with it, and others like it, but to be honest, I'm personally not a fan, so it sits on a shelf unused.

I created this video covering how my 32k memory expansion board is assembled. 

 

 

You might find it useful if you want to assemble your own from the kit form on Arcadeshopper.com

Question about the expansion header: is it supposed to passthru 5v power on pin1 from the TI expansion port or from the barrel connector?  I have no speech synth to block it.  What I'm seeing is the header pin1 power only comes from the barrel connector, regardless of the jumper selection.  I suppose I can cut the trace and solder a wire to the TI power.

 

Edit: Nevermind, I suspect this is intentional to avoid damaging the console.  Mainbyte ti99_tech.pdf says as much in a note about pins 1 and 43.

Yep. 

 

You could also just bridge all the bins on the selector jumper header. That would connect the +5v thru. But, I isolated them on purpose, thinking that if we power more off the side, we should use the barrel connector.

Dear jedimatt42,

 

Where have you bought the female edge connector and pins that can be seen in your video (I would like to buy only them on their own for other projects)?

 

 

Regards

Dear jedimatt42,

 

Thank you for your answers. Unfortunately, I forgot to also ask you following: Where have you bought the breadboard or the parts for erecting it?

 

 

Regards

A very neat and safe device now that I finished fitting the case to the 32k board.
