+Lee Stewart Posted April 8, 2020 Share Posted April 8, 2020 In the 4K Basic Support Module thread, @Schmitzi found three disk images with Disassemblers on them. As I pointed out in this post, the second disk contains an XB LOAD program that can load a GPL Assembler or a GPL Disassembler. Those two programs appear to be written in TMS9900 Assembly Language Code (ALC) rather than Forth, as was hoped. What interested me, and the topic of this thread, were disks one and three. They happen to be two different versions of René Leblanc’s Universal Disassembler, which he wrote in TI Forth. As near as I can tell, Universal Disassembler is for ALC rather than GPL. The first disk is v1.2 on a 90 KiB disk and the third is v2.3 on a 360 KiB disk. Unfortunately, neither of these disks work. As I discussed in the above-referenced thread and will repeat here, it appears that these disks were prepared from the originals by copying the three files, FORTHSAVE, SYS-SCRNS, UNIVERSAL (aka FORTH) (in that order), from the system disks with no further processing, which is verboten for TI Forth system disks because the system screens (blocks) will never be copied properly. They will all be there, just not in their proper places and almost certainly misregistered, i.e., each block’s line 0 will not start on a 4-sector boundary. The only way to properly duplicate a TI Forth system disk is to copy the disk, sector by sector. Creating a larger system disk is more complicated, but doable. I have every reason to believe I can restore these two disks to working order, unless there is more than misregistration wrong with them. My intention is to produce 90 KiB (SSSD), 360 KiB (DSDD) and 400 KiB (CF7+/nanoPEB) versions of each disk. Right now, I need to mow a lawn—TTFN! ...lee 7 2 Quote Link to comment Share on other sites More sharing options...

Both have been copied in the wrong way as explained in post #1 above. The John Volk disks are problematic. The Compilation 1 seems to work in that all of the blocks appear to be in the correct places, but some of the programs do not seem to work correctly. The Compilation 2 disk has a bad BSAVEd system, but some of the programs I checked seem to work. The disk, however, does not work as John Volk set it up. It will be tedious to fix. The v1.2 Universal Disassembler (UD) disk seems to work just fine, so we should not need to mess with that one. @Schmitzi, you should replace the one you have with this one. That leaves UD v2.3 to fix as per this thread. If any of the program image blocks are bad, we will not be able to fix them without the source code. Maybe we can see whether Mr. LeBlanc still has the source code. Even if we can get UD v2.3 to work, it would be fun to convert it to fbForth 2.0. ...lee 1 1 Quote Link to comment Share on other sites More sharing options...

+FarmerPotato Posted April 9, 2020 Share Posted April 9, 2020 Here is my original copy of UNIVDISASM version 2.3 by René Leblanc. I don't remember how I got it, but the floppy disk is from the mid 80s. I read it with Kryoflux into a 180K DSK image.

+Lee Stewart Posted April 10, 2020 Author Share Posted April 10, 2020 OK—Here are the cleaned-up SSSD, DSDD and CF7+/nanoPEB versions of René LeBlanc’s Universal Disassembler v2.3: UniversalDisassemblerV23_SSSD.dsk UniversalDisassemblerV23_DSDD.dsk UniversalDisassemblerV23_CF7.dsk Remember that this program (“UNIVERSAL”) is an E/A3 file (TMS9900 object code) and that, to use the program, you must load it with the Editor/Assembler cartridge’s option 3 as “DSK1.UNIVERSAL”. This boots up TI Forth along with Forth code for the program, which starts as soon as it is loaded. Please, let me know if there are any problems with them and if you would like the Universal Disassembler in another disk format. ...lee 3 1 Quote Link to comment Share on other sites More sharing options...

Presuming the problem can be found in screen #51 or other source code (minimal) on the disk, I will see what I can figure out. If, however, the problem is in any of the BSAVEd code, we may be screwed—unless I can raise Mr. LeBlanc and get the source code from him. He is 85 (I think), but I am pretty sure I have found him at the same address as on screen #6. I intend to write him a letter in the very near future to see whether he can lay his hands on the source code and might be willing to share. ...lee 3 Quote Link to comment Share on other sites More sharing options...
