+OLD CS1 Posted May 12 Share Posted May 12 I have a set of disks for the P-Code card. They are marked with a sticker which says, "For Internal Use Only, Not For Resale." Is there any historical reason for these to be special? 3 Quote Link to comment Share on other sites More sharing options...

Or the later control data version. Make a disk image of them and then we can compare to the current known ones. 1 Quote Link to comment Share on other sites More sharing options...

+OLD CS1 Posted May 15 Author Share Posted May 15 When I do these images, is dumping to .dsk files sufficient, or will I need to provide more detailed dumps? Quote Link to comment Share on other sites More sharing options...

+OLD CS1 Posted May 16 Author Share Posted May 16 (edited) These are the four disks marked "Internal Use Only." Note that the Assembler/Linker and Utilities disks both have bad sectors.

+Vorticon Posted May 16 Share Posted May 16 I was intrigued by a program called XCOPY.CODE on the utilities disk, but it won't execute. Quote Link to comment Share on other sites More sharing options...

+OLD CS1 Posted May 16 Author Share Posted May 16 I assume the SuperCard and FD-5025 will return the same results as the KyroFlux, but I will try the disks with bad sectors on each of those later on. I will also try another disk drive, as I am to be testing drives this week. 2 Quote Link to comment Share on other sites More sharing options...

Well, I do not have a way to determine whether these disks are any good or not. Someone else is welcome to take them on at this point. I have no use for them, and without a promise of their fidelity, there is no sense in me keeping them for archival purposes. Quote Link to comment Share on other sites More sharing options...

Try dumping a known good & full 90KB disk to an image file... I suspect something else is going on here. All 4 (so 6 now) files in your archive(s) look like they are missing data.

At this point, I do not have the time nor patience to continue mucking about with this. If someone wants these disks, they are welcome to them. I will suss out the drive imaging issues when I get back next month. 1 Quote Link to comment Share on other sites More sharing options...

Based on your selections, it looks like you may only be reading side 0, as it looks like you are set up to read a SS, 90K disk from those parameters. 1 Quote Link to comment Share on other sites More sharing options...

Are the P-Card disks DSSD? I am generating 90k images, with the last 45k (per @JasonACT) is all >00. Quote Link to comment Share on other sites More sharing options...

Any DD disks that TI made will be 16 sectors per track instead of the more usual 18 of third-party controllers (other than Myarc, which supports both formats). Those disks would have been for the Hex-Bus floppy controller though, and thus would have come from very late in the development cycle. 2 Quote Link to comment Share on other sites More sharing options...

Setting up for double-sided reports the second side as unformatted. I expect the KyroFlux to detect the correct number of sectors, if the SSSD format has any sector oddities. 1 Quote Link to comment Share on other sites More sharing options...
+OLD CS1 Posted Sunday at 06:54 AM Author Share Posted Sunday at 06:54 AM I am up later than expected, so I gave it one last whack while I am waiting for a task to complete. I changed the settings for my 90k profile, and while the image is now 180k, there is 90k of data in the image. Give this a try. After this, I am done for a while, though I would appreciate someone who gets actual 90k images using KryoFlux sharing their profile settings with me. Everything else I do seems to work just fine, just the TI images are giving me fits for all of a sudden. (I think I figured it out... I have been too distracted and too tired to realize that I should be using HD drives with these devices, not real DD drives. Hell with it.)

JasonACT Posted Sunday at 09:06 AM Share Posted Sunday at 09:06 AM Those images are comparing well with the p-code disks we have, but there's a few differences. asm-lnk: Disk names switch between using "-" and "/". Directory sector seems a bit older (less modified). No other differences. compiler: Disk names "COMPILR" vs "P-COMPILER". No other differences. editor-filer: Disk names switch between using "-" and "/". Directory sector seems a bit older (less modified). Missing "MODRS232.CODE". Due to the missing file, there's a lot of "never written" sectors on this disk. utility: There's quite a few sectors on these disks which seem to have been redacted. 1/ Names mentioning "EXTRAOI", "STRINGOP", "HEAPOPS" and "PASCALIO" appear, where the release version doesn't have them. 2/ Name "XGROM" has been removed in the released version. 3/ ? not sure about this one (file offset >14700 - 256 bytes) 4..onwards/ >E5 (sector formatted but never written) appears, where the release disk seems to be just repeating bytes of various meaningless values. 2 Quote Link to comment Share on other sites More sharing options...
apersson850 Posted Sunday at 11:14 AM Share Posted Sunday at 11:14 AM (edited) The names listed as item 1/ on the utility disk are reserved for segments that are a part of the file SYSTEM.PASCAL. That file is on the OS: volume, but can be updated by supplying selected segments in another SYSTEM.PASCAL on the boot disk. Either these segments are planned updates that then never happened or they have been included in OS:SYSTEM.PASCAL and thus aren't needed.
