My CFHDX setup. CFHDX, WHAT IS IT? If you don’t know what a CFHDX is it’s software that runs on a NanoPEB and a Windows PC that enables the transfer of files between the PC and the TI99. The software was created by the great F.G.Kaal and is on his website http://www.ti99-geek.nl/ . To do this bit of alchemy you will need a cross-over cable (or an HDX cable - more on that later) between the NanoPEB serial port and the PC serial port to transfer the files. You can also print to the PC from the nanoPEB in a different fashion using the same cable (also more on that later). HOW TO: I’m going to be describing the NanoPEB procedure which is similar to CF7+ except the NanoPEB has a serial port and the CF7+ has a parallel port and needs a special cable. For the NanoPEB you need a cross-over cable to attach the serial port of the Nano to the serial port of PC (female to female). If you don’t have a cross-over you can create a special HDX cable for little next to nothing. Here’s a picture of that HDX cable I created. THE HDX CABLE: When creating the HDX cable you only need to attach 5 of the wires. The other pins are not needed. The cable is serial female to female and here are the pins to attach: pin 2 to pin 3 which is the RXD 7 > 8 RTS 5 > 5 GND 3 > 2 TXD 8 > 7 CTS THE SOFTWARE: After you created the cable, or decided to just use a cross-over cable, you will need to download the software for the HDX from Fred G. Kaals site: http://www.ti99-geek.nl/ First part is the HDX server for the PC. On his Project Page click on TI99 HDX server and download the software. Now download the TI99 software from the Project page CFHDXS1. Install this software on your TI99. HDXSERVER The CFHDX uses the following comport settings. 38400 baud 8 bit Even 1 stop bit None You might need to set these settings on the comport on your PC before starting the HDXserver. On my XP, I did. Now start the HDXserver on your PC. Be sure the COMMUNICATIONS SETTINGS in OPTIONS are set to your comport and the CFHDX comport settings above. FILES SETUP ON HDXSERVER Next you will want to set the location of your FILES directory in OPTIONS. This is the directory where you store the files that you will be sending and receiving to/from the TI99. These are files in FIAD format much like used in Classic99 in the DSK1-3 directories. The files can be in either theV9T9 format or TIFILES format. If you store your files in a .DSK use TIDIR, or other like program, to extract the files from the .DSK. Fred recommends you keep TIDIR resident to pull the files from .DSK while running HDXserver as needed. There is also a DISKS directory that enables you to copy complete disk using another program. Personally, I never got this to work right. I kept getting read errors. I would just sick with the FILES. CHHDXS1 In E/A, or equivalent program, start CFHDXS1 on the TI99 in E/A-5. This file will be on the CFHDXS1 disk you should now have loaded on your TI99. I load mine into DRV1. When the HDXserver detects that the CFHDXS1 is running you will get a message in the below message area: TI99HDX: <TI99/4a initialized, HDX Version xx> CFHDXS1 USAGE When CFHDXS1 starts on the TI99 read the HELP screen then of all the shortcut keys then PRESS ENTER to start the CFHDXS1 server on the TI99. Start typing and this will fill in the SRC which is HDX1. (be sure to add the period). This now displays the content of the FILES directory from your PC. Some action keys from the HELP screen: Function-2: marks files. Function 6: brings up COPY/DELETE/MOVE/(UN)PROTECT bottom menu. This will perform the actions on the files you marked with Function 2. For COPY/MOVE a question of DST, which is the destination, is required. Set DSK1-3 as the destination. Press H for the HELP screen from the beginning and a list of the other commands. That’s about it for the HDX on the NanoPEB. Useful? Sorta. It’s not really good to pull the CF card in and out of it’s slot of the NanoPEB too many times. That connector isn’t the most durable thing in the world. Still, if I had a lot of files to transfer I would still pull the CF and use TIDIR on the PC to transfer the files as it’s lot easier and faster. That’s it for Now. HLO PS I'm going to create a separate blog for the printing using a VT100 terminal emulator on the PC. Also, ignore the 2 pictures at the bottom, I can't seem to get rid of them for some reason.
Has anyone else experienced errors while trying to copy files to their HDX server? I can reproduce it every time doing these steps: (Assume cable, HDX board, and Server are working - which AFAIK they are, as everything else works) 1) Launch DM2K (v2.5b) on TI with Editor/Assembler 2) Source: "DSK1." 3) Select ALL files (contains about 18 files <180k) 4) Hit Proc'd 5) Choose Copy 6) Destination: "HDX1." It will start to copy files to the HDX server and I can see records being transferred. But in the middle of a randomly chosen point of a file; HDX will crash/hang/unresponsive. Within a few seconds DM2K will report "error 6: Opendst [Device error]" At this point, I'm dead in the water. HDX server is hung, I have to force it to close and get the Windows message of application in not responding. This ONLY happens when copying files TO the HDX server using DM2K. But then, I don't have any other method to "copy" files to and from the HDX server to compare against. Can anyone with a fully functioning HDX server try this; and tell me if it fails or works for them? The goal is to copy my utilities disk (DSK1) to HDX1 but I can't get it there!!!! TIA! -Dano
NOTE: Before reading this blog you might want to read the previous blog on the CFHDX. Here is another interesting use for the NanoPEB and the CFHDX cable or cross-over cable, the ability to print from the NanoPEB without needing to find a, nearly impossible to find, serial printer. HOW TO: As with the CFHDX attach the NanoPEB to your PC using the CFHDX cable (see previous blog) or a cross-over cable. Now set the comport on the PC to: 300 7 bit odd parity 1 stop bit none Start up a VT100 terminal emulator on the PC and also set the port to the same. Now print anything on the TI99 to the "RS232" port and it will be sent to the VT100 screen. Use your VT100 software to print, save or whatever you want to do to the data. Here is the printout of a small program in the VT100 from the TI99 using LIST "RS232" my setup
I have opened up a pre-sale for HDX boards to modify your TI rs232 card to support the HDX1 DSR http://www.arcadeshopper.com/wp/?page_id=11#!/~/category/id=5051340&offset=0&sort=nameAsc For more information on HDX read on: Have you looked at Fred's site? http://home.vodafonevast.nl/fgkaal/Software/sw_ti99hdx.html#ti99hdx Basically HDX makes a network like connection over the rs232/2 port to a windows PC. It is a DSR replacement on the RS232 card and provides a device HDX1 that connects to software on the windows PC. Providing a "hard disk like" device to access v9t9 format files on the windows hard disk. Theoretically you can point classic99 to the same folder and run/access the files there on your PC without having to convert/move/copy them somewhere else. It also allows the use of TIPRINT on the windows pc to emulate printers and you can print to HDX1.PRINTER on the TI and it comes out on your windows printer. Both of these software packages can run on the PC with just a regular straight through serial cable. But to use them "seamlessly" on the TI requires the RS232 modification which uses the board I am selling. The board loads a new DSR into a battery backed static ram (very similar to minimem's memory as he borrowed that design) and that DSR has instead of RS322/2 it has the HDX1 device. A RS232 splitter cable is required to split RS232/2 off of the main connection for the connection to the PC. The cable required other than that is straight through DB25-DB9. To use HDX without the board you load the program CFHDXS1 on the TI and that allows a limited DM2K interface with HDX1 support built in. This is what I've used for months to transfer files to the TI from the PC, all I do is us TIDIR to put the files in my HDX files directory (or a sub directory) then load the software on the TI, go to HDX1. and there's the files and directories. Long as they are v9t9 format (TIDIR lets you easily convert to that if they are not) they come up and are copy, move, eXecuteable from CFHDXS1 or any program if you have the modified RS232 card. TIPRINT lets you print to RS232.BA=xxxxx. etc.. and it comes out on your PC's printer. Again with the HDX board modification you can print to HDX1.PRINTER and it will figure out the rest. There's also a Disk transfer program that works with the HDX board that will copy your disks from the TI directly to a DSK image on the PC in a "disks" directory. And you can copy DSK files back to real disks on the TI as well. I have used the software version with both Corcomp and TI rs232 cards and they worked fine. I haven't tested with anything else.. The modification of the card for the HDX board ONLY works on a TI card. No 3rd party cards. I am going to purchase a few extra RS232 cards and build them up with the HDX modification and offer them for sale if people are interested in the mod but not the build I am sure a few others are as well based on the quantities ordered from the pre-order.
