Didn't find anyone with that name? eBay Seller: schmutzig1952 This link, btw, was made using AA's BBCode (button next to the Font drop-down) and nothing more than the seller's name Quote Link to comment Share on other sites More sharing options...
Sincity Posted July 23, 2017 Share Posted July 23, 2017 How do you test these things out? I purchased one last year and finally had time to play with it (after assembling my Flashrom99 also purchased last year). On one machine, all I get is a blank screen. On another machine, I tried loading a several ROMs that require 32k and they don't load. Quote Link to comment Share on other sites More sharing options...
Casey Posted July 23, 2017 Share Posted July 23, 2017 If you don't turn on the power switch before turning on the TI, all you'll get is a blank blue screen. If all is well, you'll see a message on the title screen (see screenshot in the TI photos thread - I just posted one with my NanoPEB plugged in). Extended BASIC will also show you the memory expansion is available if you issue the SIZE command. Quote Link to comment Share on other sites More sharing options...

Everett1954 Posted July 26, 2017 Share Posted July 26, 2017 Here is the power supply I use. Proper voltage and current rating, correct polarity plug. You can't beat the price 2/$10.99 and free shipping if your an Amazon Prime member. https://www.amazon.com/gp/product/B01M261XMQ/ref=od_aui_detailpages00?ie=UTF8&psc=1 BTW my NanoPEB arrived with a broken ON/OFF switch but was promptly replaced. It also came wrapped in bubble wrap in a padded envelope. He sent the 2rd in a box. Now all is good! Do we know what the specs are for the TI internal power supply are? Enough current to supply both the speech synthesizer and NanoPEB? I would love to drop the added wall-wart but not if it means over-currenting the internal power supply.

I would love to drop the added wall-wart but not if it means over-currenting the internal power supply. Given commonality for all the variants out there, these are pretty ballpark: +12VDC @ 400ma +5VDC @ 1.1A -5VDC @ 200ma Quote Link to comment Share on other sites More sharing options...

I would love to drop the added wall-wart but not if it means over-currenting the internal power supply. Oops, I see now it was talked about in the previous page... but in case you missed it, when using the NanoPEB and the speech synthesizer together, you'll still need that power adapter. Unless you mod your SS by adding a jumper, it does not pass thru the +5v off the connector. Quote Link to comment Share on other sites More sharing options...

globeron Posted August 13, 2017 Share Posted August 13, 2017 Today I tried both my NanoPebs, which used to work well all along, but both do not come up anymore (only the Blue blank screen) (I tried consoles with and without F18A, with and without Speech, I have the 5V supply which normally is okay). I tried all combinations / on-off switch, power on/off. but I did not take out the jumpers (if that may help?) Does someone have a clue what could be the reason? (maybe that I did not used them for several months ?) (it seems to be only NanoPEB related) as without the nanoPeb everything works normal. I was wondering if I need to burn the chips again (there are 2x chips), I have a burner (TL866), but I do not have the source of the files to re-burn these nano-Peb chips (if needed?). I guess it is a bit similar as how the UberGroms are made. Quote Link to comment Share on other sites More sharing options...

Omega-TI Posted August 13, 2017 Share Posted August 13, 2017 (edited) Nano's can be flaky little devices. It's the main reason I don't like them. I had the same issue on the last Nano I used to own. What finally corrected the problem for me was removing the socketed PLCC's and using some fine grit sandpaper on their contacts. Once re-installed and reseated it worked fine. I had nothing else to lose at that point. You might also want to give it a try. Edited August 13, 2017 by --- Ω --- Quote Link to comment Share on other sites More sharing options...
globeron Posted August 13, 2017 Share Posted August 13, 2017 Today I got one to work again for a while and now it is back to the blank light blue screen. I first thought it had to do with the CF-card. (thanks to Ralf, I now first time see that the whole socket can be taken out, the L-shape, I was already wondering how to get both PLCCs out of the sockets. Will try that as well. I have a backup of the CF-card and think files are still there, but it is now my only fast way to get all type of files to the TI without taking to much space. I agree, it is flaky (the RS232 never worked for me) - I want to move to FinalGrom, but also want to try the UberGrom+RS232-HDX option (but I waiting for 2+ months on it from China supplier has some issues with the postal services, they try it now again). 1 Quote Link to comment Share on other sites More sharing options...

I had nothing else to lose at that point. You might also want to give it a try. I just did that, but also did not work, still getting the blank screens. PS. I am using F18A V1.6 VGA. When I do not turn on the power of the nano-PEB, then I see the F18A green/black screen (not really sure if this is an issue, as nano PEB should work on non-F18A consoles as well and here I get a black screen also) The only thing I can think about is to re-burn the PLCC. Could that be an issue that they get corrupted (loose their memory or so? when not using them for a while?). The power adapter is 5V / 600mA, but also always worked fine. one NanoPeb has a jumper JP2 on the right two pins, the other one not. One has the green led light up and other one not, but I remember that both were working okay. Is there a way to do resets or so? (e.g. holding buttons on the TI, like FCTN-xxx or maybe join pins together on the nano-peb?) Other items, I always use the Speech Synthesizer in between, because it is easier to get the nano-pebs out, I have tried without but no difference as well.

+chue Posted August 13, 2017 Share Posted August 13, 2017 I just did that, but also did not work, still getting the blank screens. Mine sometimes blanks out when it hasn't been on for a while. For me a simple reboot/ reset of the TI does the trick. 1 Quote Link to comment Share on other sites More sharing options...

I also tried that, it does not work. I am looking fwd to the FinalGrom to use it. I have the 32K side modules already and they work fine. but now I realise then I do not have the DSK options like the nano-PEB has, that was convenient to load my old disks into the TI, Quote Link to comment Share on other sites More sharing options...
Sinphaltimus Posted August 14, 2017 Share Posted August 14, 2017 I've found something strange happening with my nanoPEB. "Sometimes" it doesn't turn on. I've found I have to unplug the power and plug it back in then it works - very odd. So I have my TI and all things plugged in to it connected to a power strip with power switch. i turn that on and off when I'm using/finished using my console. That seems to have solved the nanoPeb issue. Maybe killing the power supply to the nanPEB when turned off helps with other issues? Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted August 14, 2017 Share Posted August 14, 2017 Being that Nano's are such flaky devices, I'm sure that is one reason, among many, why people are patiently waiting on the TIPI project, which will probably be a major game changer. 2 Quote Link to comment Share on other sites More sharing options...

+Vorticon Posted August 15, 2017 Share Posted August 15, 2017 It seems the NanoPEB is very sensitive to the power supply specs. Mine worked fine with a 300mA 6V supply that came with my original CF7+, but the serial port was flaky. I tried a couple of different 6V 2A supplies and it became erratic. The sweet spot was a 6V 1A supply. That does not make much sense I know, and I suspect that the real culprit is the quality of the power supply used. All of mine are made in China, and when I have a moment I'm going to analyze them in detail. I may be excessive ripple, or poor load tolerance or who knows... I never throw away power supplies from broken equipment because I can always find a use for them, but these days most of these are likely of poor quality. If anyone here has a good source of reliable power supplies in the US or Europe, I would love to hear from you. Yes it may cost more, but it will be more than made up for in reduced aggravation... 4 Quote Link to comment Share on other sites More sharing options...
