Opry99er Posted October 5, 2015 Share Posted October 5, 2015 I have an HDX-modded rs232. I Have a pigtail with an HDX out and an rs232 out. I have a 6" crossover cable. I have a db9 serial port on my PC. I THINK all I need now is a null F->F db9 cable long enough to reach the PC port. Is this correct?

Shift838 Posted October 5, 2015 Share Posted October 5, 2015 If I remember right I just used the standard 25p to 9 pin null modem cable. It's been awhile, someone else that is currently using the HDX can probably chime in for sure though. Quote Link to comment Share on other sites More sharing options...

It's a DB25 on the TI end to two 9 pin Ds. One for HDX the other for serial. From there, it's a 9-pin null modem to your PC. Quote Link to comment Share on other sites More sharing options...
Opry99er Posted October 5, 2015 Author Share Posted October 5, 2015 Cool... So, once I get the cable linkup complete, there is no software I HAVE to have on the TI side in order to start transfers, correct? I got high on the HDX train a couple years ago, but didn't complete the setup due to space constraints and then two moves. Now I have the space, I have the desk, I have the components (minus the long db9 cable) and I reeeeeeally need to get set up. My next project (after Vector Hyperdrive) is do some conversions of a few of my games to straight XB (with no assembly support) and put them onto tape. Then I want to write a game on 100% TI hardware for tape as well. Should be fun, but I need a reliable transfer system in order to do this stuff.

Is this correct? you just need a straight through cable.. crossover is for a nanopeb. I just use a 9-25 peecee cable adapter and a 25-25 cable from my ti to that.. Greg PS: About time!

Omega-TI Posted October 5, 2015 Share Posted October 5, 2015 Cool... So, once I get the cable linkup complete, there is no software I HAVE to have on the TI side in order to start transfers, correct? Yes & No.... If you are just loading up a program, you do NOT need any additional software just load your programs like you would normally, with the exception of the path. Now if you want to easily make DSK images of all your original disks and save them to the PC as backups, you'll want to download and use DSK2PC, but it's free software available on Fred's site. To thsoe unfamiliar with the HDX, you can get a overview << HERE >> Quote Link to comment Share on other sites More sharing options...

Omega-TI Posted October 6, 2015 Share Posted October 6, 2015 if you have any weirdo problems, check the battery on the hdx board, and reload the dsr Greg AB-SO-FREAKIN-LUTELY! I had all sorts of weird crapola happen when the battery was dying. Once I got a NEW battery, I've had ZERO trouble since. In fact that issue spawned << THIS THREAD >> and << THIS PROJECT >>.

Opry99er Posted October 6, 2015 Author Share Posted October 6, 2015 Reloading the DSR. I hope to not need to do this, but could someone link me to some good HDX info? I am not sure what I will need to accomplish this. I just need to do some reading from start to finish on this mod... Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted October 6, 2015 Share Posted October 6, 2015 It's not hard, in fact it's fairly simple. The attached disk image has everything you'll need. Just load up the program, answer the questions and it'll program itself. rs232hdx03.zip 2 Quote Link to comment Share on other sites More sharing options...
Opry99er Posted October 6, 2015 Author Share Posted October 6, 2015 If this is required on the TI side, however, and I DO need to replace the battery, I have no way of transferring. My MFM disk got whacked a couple years ago when I was trying to copy it for a fellow 99er. Quote Link to comment Share on other sites More sharing options...

Opry99er Posted October 6, 2015 Author Share Posted October 6, 2015 Might not need it. I'll let you know when I get the cable I need. Stinkin office max, staples, walmart... Even radio shack.

Opry99er Posted October 7, 2015 Author Share Posted October 7, 2015 Here's what I've got now... (gregallenwarner was kind enough to make these up) #1: This first cable is a 25 pin male cable that splits into two db9 male ends... one marked "HDX1" and one marked "RS232/1" #2 This second cable is (obviously) a X-over cable, one end is db9 male, the other is db9 female. I guess I only need the crossover if I am connecting to a nano? So... The serial port on my PC is a db9 male, into which a db9 female end will plug. So I will need a db9 female to db9 female straight through cable to complete the setup, correct? Just want to make ABSOLUTELY certain before I order.

Opry99er Posted October 7, 2015 Author Share Posted October 7, 2015 Maybe something like this would complete my interface? http://www.amazon.com/StarTech-6-Feet-Straight-Through-Serial/dp/B00066HP2E/ref=sr_1_1?ie=UTF8&qid=1444201714&sr=8-1&keywords=db9+female+straight+through Quote Link to comment Share on other sites More sharing options...
+jedimatt42 Posted October 7, 2015 Share Posted October 7, 2015 Given that your crossover cable has 1 male and 1 female end, then a simple gender change should complete your link... I personally used TI splitter and a null-modem as shown here: http://www.ti99-geek.nl/Projects/ti99hdx/Files/ti99_rs232_splitter_cables.gif where my null modem has the DCE gender on both ends. https://en.wikipedia.org/wiki/Null_modem 1 Quote Link to comment Share on other sites More sharing options...

+jedimatt42 Posted October 20, 2015 Share Posted October 20, 2015 What kind of battery life do you get out of the CR2032 powering the SRAM on the HDX DSR board? I know I've seen pictures of nicely placed switches to power off that SRAM when it gets corrupted. I've been experiencing that corruption preventing boot regularly, so I just pulled the battery, and just have to reload each session. I'm sure I'll tire of that and wire a good switch in copying Ω's disk drive drawer technique... But in the meantime, what has your experience been with battery life?

Omega-TI Posted October 20, 2015 Share Posted October 20, 2015 Six to nine months... of course as luck would have it I got a bad battery once and only got a month. Good luck. BTW Dollar Tree carries a pack of two CR2032's for just a buck! Quote Link to comment Share on other sites More sharing options...
+jedimatt42 Posted October 26, 2015 Share Posted October 26, 2015 Is there any reason that the HDX DSR board can't just be a couple eproms? Does it use the RAM at runtime for buffers? Quote Link to comment Share on other sites More sharing options...
