MueThor Posted March 17, 2017 Share Posted March 17, 2017 (edited) Dear --- Ω ---, You never reacted to following: Quote ..., 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?

Omega-TI Posted March 17, 2017 Share Posted March 17, 2017 Dear --- Ω ---, You never reacted to following: Quote 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. Quote Link to comment Share on other sites More sharing options...
+jedimatt42 Posted March 21, 2017 Author Share Posted March 21, 2017 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 -M@ 10 Quote Link to comment Share on other sites More sharing options...
PeteE Posted May 23, 2017 Share Posted May 23, 2017 (edited) 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. Edited May 23, 2017 by PeteE Quote Link to comment Share on other sites More sharing options...

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. -M@ Quote Link to comment Share on other sites More sharing options...

Omega-TI Posted January 18, 2018 Share Posted January 18, 2018 The 32k is a prerequisite for TIPI due to power right? Quote Link to comment Share on other sites More sharing options...
+jedimatt42 Posted January 18, 2018 Author Share Posted January 18, 2018 The 32k is a prerequisite for TIPI due to power right? Yes, the sideport version of TIPI requires my 32k sideport card as a base for the entire header style expansion port instead of edge connector expansion port. Unless of course someone else does something else with my designs. -M@ Quote Link to comment Share on other sites More sharing options...
polyex Posted April 18, 2018 Share Posted April 18, 2018 It the sideport does indeed provide enough juice to run the speech & my 32k board. At least empirically. I don't want to sever a connection so I can measure the load of the speech + 32k.. But the "parsec from FlashRom99" test worked well... speech and running the game out of the 32k ran without a hickup. Here is a picture of what I did to the speech synth, and then I ran my board with the jumper set to 'TI' Modified speech synthesizer (blue jumper wire across pin #1): speechsynthpower.png Anyway, since Stuart suggested I should be able to run with such lower current so many posts back, this has been a target. Oh, and to be clear, the boards that went to print have this option built in already. -M@ I did the same thing, but I am getting weird behavior. Just the 32K plugged in works fine, and just the synth plugged into my PEB works fine. But if I go Synth->32K I get memory check errors. Not sure what is wrong.

In recent TIPI testing, we found a speech synth that caused trouble, a cleaner one worked fine.. When you put your speech in the PEB there are buffers in the flex cable that enhance and recondition the signalling. When you put the speech between the 4A and the 32k, there are no such buffers. Usually that's fine, but the pass through on the speech has to be in good shape. There are 30 some signals used that could go wrong. I would start by cleaning the edge connector contacts on the 4A, speech edge socket, and speech edge connector. But, why if you have a PEB are you playing with a sideport 32k? That doesn't make any sense to me. -M@ Quote Link to comment Share on other sites More sharing options...

The design files are up there and public. But I'd like folks to keep in mind, that I'm $835 upside down on TIPI right now. And I haven't prototyped the PEB board yet. So more expenses ahead. But yes, I will wish for some scenario that doesn't require this to be the only thing I ever do again, as soon as I am right-sided. -M@ 2 Quote Link to comment Share on other sites More sharing options...

I remember the days of putting the money upfront and hoping I’d get it back, so I completely understand. Let us know when you’re comfortable with others helping out.
