It doesn't work for me on XP either. All other previous verisons to 9.1.a do work without any problems. The error says it is not a valid WIN32 application. This is on a 32bit XP SP3 system. Back to version 8.3.e for the time being.

For sure with the hard work on combing through the code for the fix. The level of effort is greatly appreciated by other users. Beautiful stuff to behold for these old classic computers.

Indeed, the PEB "piano" brick strikes again. Who knew that TI had designed a weapon of mass destruction back in 1980 or thereabouts.

For sure as it could also be used as a bunker busting bomb when dropped from a few feet. It's a good measure to wear steel-toed work boots when handling that dead weight.

Good suggestion as these old cards need all the help in extending their functionality as heat being the number one enemy towards any electronic component. You still have to hand it to TI for building these system. The old PEB was manufactuered to military standards at least by today's standard. LOL.

That's looks awesome. Can't wait to see a fully built unit.

I tried this modification and it does work very well. Be careful in removing the existing ROM chips as the traces are quite close. I did not have the proper equipment to do it so I brought it to a local electronic repair shop. They desoldered the ROMS without any damage, soldered the sockets in less than hour. I used the 80 track eprom for DSK2 and DSK3 and 40 track eprom for DSK1 since I have a 3.5" diskette as DSK2. It works great formatting the 3.5" drive using either 40 or 80 tracks. One thing to bear in mind that you must use Disk Manager 2 to format to 80 tracks or Fred's DM2K. DM1000 will not work as it's limited to 40 tracks. I will now try the other set of eproms that will allow 80 tracks on my doble sided DSK1 5.25" floppy drive that already supports 80 tracks. This will make it easier to copy between the 3.5" and the 5.25" drives. This project is a great addon to the PEB FDC. Not sure why pushed the 40 track system to begin with.

It would simply things quite a bit IMO and provide all the floppy/disk drive power in a modern style case. Making the railing support cage would be quite simple especially if one would use the existing setup in the PEB assuming your IO board spacing is the same. Regardless, good stuff for the old TI99/4A.

Did you ever consider using a typical PC styple computer case that already has the ATX power supply and drive bays? It might be quite easy to install your IO board in the same area where the motherboard would be installed. Just a tought.

That is one ambitious project. I'm sure that when you complete the project, many users will probably upgrade their systems with it.

Looks like a great project. What about keeping the existing PEB but replace the outdated power supply boat anchor with a typical PC ATX style power suppy instead. Just wondering if anybody has done that upgrade before. Roger

It would be nice to have something similar to: DIR > PIO.CR. or DIR > CATALOG (a DV80 file) and then use the TYPE command with the CRTL-W as you noted. As you hinted, this might come about down the road.....fingers crossed. BTW, forcecommand is an incredible tool on the TI99/4A. Kudos for the great work and the ongoing support that you provide. Thanks.

Is there any way to redirect the TYPE or DIR command to a printer like PIO or RS232? Just wondering how to print a directory listing of a drive or a DV80 file from the command line. Cheers Roger

And now I know why I'm not able to create the directories under a TI-99/4A setup, HDR4000B simply doesn't support it. Just wondering if the TI99/4A works with the IDE card, then why not with the HDR4000B. I suspect it's related to legacy code that goes back to the original HRD design. We can only hope that a future ROS release will include directory/sub-directory support.

That's great news. Looking forward to it. Thanks
