| 詳 細 | Older version of mess (like 0.161) supported 200k disks, i.e. SSDD or single sided double density (or 80 tracks). In newer versions this is changed to only SSSD or single sided single density (or 40 tracks), so 200k disks not boot anymore! Note: I found that this has been already discussed on forum (see link below) but the problem is "double density or 80 track disks" and not "double sided disks"! I am not sure is double sided disks supported on other emus, but on "ht1080z1.6.6" emu double sided disks are not supported, only SSSD and SSDD works. forum - support for double sided drives: http://forums.bannister.org/ubbthreads.php?ubb=showflat&Number=104182&page=3 I guess this can be easily fixed! EDIT: Hmm, seems "TRSTools1.12" also not support double sided disks! (at least the one called "dick-smith-system-80-diagnostic" ... hmm, but "sdltrs_win32_1_1_0" emu boot it fine!) Btw. used disk format (40 or 80 tracks / single or double density) can be easily checked on tool like "HxCFloppyEmulator" in Track Analyzer / Disk View ! Maybe the best solution would be if DSDD drive (double sided double density) is supported! NEW: hmm, or maybe not... http://www.trs-80.com/wordpress/hardware-replacement-floppy/#svd on above link for replacement floppy says: (see quote below and my notes on right side) ------------------------------------------------------------------------------------------------------------ Current features of the SVD are: Up to three diskette images can be loaded at once (drive 0, 1, and 2) up to 256k single-sided single density (SS SD) ................................................................................ <--- (note this !!!!) double density (SS DD) .......................................................................................................<--- (note this !!!!) reading/booting the diskette image writing the diskette image LEDs for power, drive0/1/2, track0, and write Supports Model I, III, 4, 4P and CoCo. DOES NOT SUPPORT DOUBLE SIDED DISKS. ...........................................................<--- (and note this !!!!) ------------------------------------------------------------------------------------------------------------ So, according to above, maybe the "double sided disks" is not necessary to emulate!? | ||||

| 追加情報 | Common File Formats for Emulated TRS-80 Floppy Disks http://tim-mann.org/trs80/dskspec.html EDIT: According to above Model 3/4 should use the JV3 disk format ! (but it seems that current mess uses JV1 disk format for Model 3/4, what is wrong) The disk format JV1 should be used for Model 1 and JV3 for Model 3/4 only! Here is an example for JV3 disk format: http://www.sol20.org/vmedia/sol20_clones.zip (Note: TRSTools reports for this JV3 format) Above is bootable on Model3 (tested) in other emu, but not in mess Model 3/4 driver !? (and of course, it does not work on Model 1) | ||||
