Looking at this photo makes me think, "Yes".

 

Awesome. That looks great. I have a PEB with 32K, rs-232, and ti disk controller, so it looks like I'm set. I wouldn't mind getting a 32k sidecar though.

This week's progress: I've been able to play Wizard's Doom, Old Dark Caves 2, Legends, Legends 2, and Panzer Strike.

Their save game mechanisms all work as well. Although, I haven't run through the l2conv disk for Legends 2.

The Sideport TIPI has no power port. It expects to get it from the +5v pin on the 32k board's expansion header. The 32k board won't offer +5v on that pin, unless an external power supply is used (as designed).
 

 

This just jumped out at me.  I don't know why I missed it the first time I read it.  Anyway, since you are the creator of both, what do you recommend in milliamps to supply both?

I haven't measured the TIPI board's consumption yet. But I'd guess it is less than 100ma.

Some 32k boards use 65ma, some use 25ma.

These are what I'd recommend:

Ive got a 32k sidecar preordered from Arcadeshopper along with a power supply (and a joystick adapter for good measure ha). Ill be ready when the TIPI is available to order. The only thing I dont have on my setup is storage because I dont have a nonfried disk drive right now, so Im thinking I will wait for TIPI to be my storage answer. I would be interested in double sided drive if I can find one at a reasonable price. I had 2 slimline drives in my peb at one time.

The case that comes with the Rpi kit that Shift838 recommended is actually quite good.  If we do end up having a sleight height issue with the cabling, a specially designed TI logo 'added height' replacement top could be made with perfect slot/hole.

Perfectly understandable, and expected from an excellent hardware guy like yourself. :)    In my case, admittedly not being anywhere near your league, I am relegated to just looking to the future on how best to dress up the little gadget to my own personal taste.  It's about the only fun and excitement I get while I wait for the big day when TIPI changes everything for the TI enthusiast.

For everyone the kit I recommended based on the case is because the case is solid, and the top can either be completely removed or since it's plastic can easily be modified....So it should work nicely when the Ti-Pi is released since we will need to open the top part because of the GPIO headers and cable for the Ti-Pi.

 

Should be easy enough to dremel it straight...That's my plan anyway..

Here is another quick demo of using the web administration to copy/paste some BASIC code into a web form hosted on the TIPI, then loading the code on real hardware and running it.

I anxiously await giving you guys my money. I’ve got a sidecar 32k ordered, and 1 of my 3 Raspberry Pi’s available. Really looking forward to it!
