+arcadeshopper Posted February 16, 2017 Share Posted February 16, 2017 Am using a serial -> USB convertor - hmmm may well even be that - I might try & install a serial card on the PC - good thinking! Either that or try another usb adapter.. the ports on the TI tend to be picky about signal.. I use a FTDI chip USB adapter and it works great for HDX but others have had very frustrating times with USB adapters that don't work right with the TI you will always be better off with a real card Greg Quote Link to comment Share on other sites More sharing options...
palmheads Posted March 1, 2017 Author Share Posted March 1, 2017 I modified Mass Transfer (40 columns) to work with the nano. I didn't retrofit it with my high-speed routines, so the best speed is 2400 with dropped characters at 4800. I uploaded it to Heatwave for test purposes. Since I am still waiting for the power cord for my nano, I could only verify the program operates with a standard TI. Hi InsaneMultitasker I think I've grabbed the right disk off Heatwave. The file was called '@MT74NANO' which is a DSK that contains these 3 files: MX74 MX75 MX76 Looks like I can load 'MX74' from the Editor/Assembler cart using "RUN PROGRAM FILE". Sounds about right? cheers Daryn Quote Link to comment Share on other sites More sharing options...

palmheads Posted March 3, 2017 Author Share Posted March 3, 2017 You got it. Hopefully it will work; I really hate not being able to test things up front! Gave it a go last night (after remembering how to add DSK's to the CF card for the nanoPEB!). Going through the Run Program File, DSK1.MX74 etc etc didn't load and gave me an error 7. Will try again in the weekend making sure I have the right files on my CF Card, 'cos it seemed to work on classic99 doing the same exact thing. Will let you know!

I'II repeat what I did & just make sure, because I was in a hurry. Quote Link to comment Share on other sites More sharing options...

Will try again in the weekend making sure I have the right files on my CF Card, 'cos it seemed to work on classic99 doing the same exact thing. I transferred Mass transfer 7.4 to my nano's CF device. I was able to load the program using Editor Assembler option 5. I grabbed a standard 9-to-25 pin cable, connected it to my UDS, and was able to telnet into Heatwave at 2400bps. I am glad Jaime used a standard 9-pin RS232 pinout so that I didn't have to make my own cable! I'm currently downloading a few files to the nano via Heatwave for testing... Hopefully your load problem is simple to resolve. You are using ALL CAPS, right? (and the file on the disk is capitalized?) Quote Link to comment Share on other sites More sharing options...

palmheads Posted March 5, 2017 Author Share Posted March 5, 2017 Woo! Tried my DSK on js99 & got the same error. So loaded the files back onto it this time in v9t9 format. Worked on js99. Then copied back onto CF card (all the time using xdt tools) and success! Loaded great. Thanks InsaneMultiTasker & everyone else. Unfortunately it looks like I may have a faulty serial port on my nanoPeb. Still can't get an echo happening in Terminal mode from the TI to Linux using picocom. Will keep a lazy eye on a new nanoPeb. Cheers everyone. Quote Link to comment Share on other sites More sharing options...

palmheads Posted March 5, 2017 Author Share Posted March 5, 2017 I guess thats the only other thing - it could be my null modem cable. Have attached some piccies. Typing stuff in TERM mode on Tandy 102 Echoed out using picocom on ubuntu So I know it "can" work. For the TI, have now tried 3 different serial->usb convertors (left of piccie) The middle one has FTDI. The top one is the one I use with the Tandy. This is the null modem cable I am using Settings in Mass Xfer Typing stuff in Terminal mode Nothing appearing in Ubuntu. Tested with all 3 serial->usb converters. Will keep on playing, will try another null modem cable. Or maybe a proper serial device on an old PC. cheers Daryn Quote Link to comment Share on other sites More sharing options...

I would think that maybe it's the cable or (hopefully not) you have a bad serial port on the Nano. Quote Link to comment Share on other sites More sharing options...
palmheads Posted March 14, 2017 Author Share Posted March 14, 2017 Hmmm - one thing I haven't tried is getting hold of a straight through RS232 cable. InsaneMultiTasker - your post here: http://atariage.com/forums/topic/240729-midi-module-or-synthesizer-connected-to-the-ti-994a/page-3?do=findComment&comment=3717509 Might indicate it would have more chance to work than perhaps a null modem cable?

Or no real difference? Pretty sure you need the null/cross-over cable as you are connecting two DTE devices. Are you certain your cable isn't a straight-through? (I don't know how a Tandy COM port is wired). There are some cables that don't pass all the signals. Are you able to test the cable with a continuity tester? When you type from the Mass Transfer side, does the cursor keep blinking or does it 'lock up'? The latter could point to a CTS/RTS issue; see my most recent post in the midi thread.

Omega-TI Posted March 14, 2017 Share Posted March 14, 2017 The Tandy Model 100 & 102 were fun portable machines BITD. I used to have the NEC PC8201A version. It had two banks of 32K. I also had mine hooked up to my TI-99/4A. I always wished the versions of BASIC were more compatible between machines. With all these "SUPER CARTRIDGES" we have now days it would be kind of cool if a version of GWBASIC was available for the TI. Quote Link to comment Share on other sites More sharing options...

Therefore it should also connect to the nano with a null modem, but your cts/rts you found on the midi cable may be the issue. I connect my nano to the PC for HDXS with a null modem.

palmheads Posted March 20, 2017 Author Share Posted March 20, 2017 Just for completeness, I purchased an RS232 Straight thru cable - nothing with picocom & linux. My very last hope is purchasing the USB->Serial that Greg mentions in another thread: https://www.amazon.com/gp/product/B00AHYJWWG/ref=od_aui_detailpages00?ie=UTF8&psc=1 If that doesn't work then I will see if a new nanoPeb fixes the issue Quote Link to comment Share on other sites More sharing options...
palmheads Posted May 19, 2017 Author Share Posted May 19, 2017 OK got hold of another nanoPeb. Worked first time! So TI using Mass X'fer (MX74) & nanoPeb with null modem cable connected to Ubuntu Linux and picocom! Got a echo terminal working! Great! Will try my Tandy 102 in the weekend!!! 2 Quote Link to comment Share on other sites More sharing options...
