I was wondering if anybody out there is familiar about running a Model 4
in the Model 3 mode. I've heard that all you had to do is boot up the
Model 4 with a Model III system disk. Is this correct?
Another thing is which Model 3 operating system should I use that's the
best or most compatible. I've read in Micro 80 that Miosys(sp?) offers
a LDOS 5.3 operating system. Is this any good? Is this all I need or is this
LDOS 5.3 purely an upgrade meaning I need a disk previous to this to use
this LDOS 5.3? I'm confused. Any help offered greatly appreciated.
One more thing any used the new LDOS 6.3(upgrade for TRSDOS 6.2) that is
also available?
Thanks in advance.

In order to use a Model 4 in the Model 3 mode, you need to have the file "MODELA/III" present on the model 3 diskette. When the 4 boots, it will look for this file on your diskette and go into the appropriate mode. The "MODELA/III" file should be supplied along with the DOS disk from Radio Shack.

A model 4 contains all the rom that the original three had. (excluding 4p's) That is how they made the model 4 64k instead of 48. The model three used the rest of the space for basic rom. So using basic on a 4 uses up ram, so you end of with less user memory than the 3 had in the first place. As for a model 3 operating system, borrow a copy of trs-dos 1.3. It may not be as elegant as many others, but it works just fine, does what you tell it to do, quickly and efficiently without many glitches. Actually I have yet to see any. And because the machine was sold with trs-dos it ends up being the most used operating system. Thus the most suported. Remember to Press reset whenever you switch operating systems!

Sure is correct, in fact, I play some model 1 games in model 3 mode on my model 4; say that 10 times fast :^). The 4 defaults to being 100% Model 3, you have to tickle a few ports in order for it to realise its a model 4! Any model 3 software will work on a 4. > Another thing is which Model 3 operating system should I use that's the >best or most compatible.

LDOS 5.3 is all you need, it would help if you could get ahold of an old Radio Shack Hard Disk System Manual, an LDOS manual by any other name. Also, if you already have the TRSDOS 6.x manual you basically have the LDOS 5.3 manual. 5.3 comes with EXTENSIVE help built in so the manual isn't 100% neccessary. LDOS 5.3 has alot of nice features so if you have to be in model 3 mode, LDOS 5.3 is the only way to go. As a side, Misosys makes THE best software for the models 1/3/4, its owner, Roy Soltoff, wrote most of LDOS 5.x and a good majority of TRSDOS 6.x. Get a catalog if you order LDOS 5.3 from them, I think you'll get one automatically but it doesn't hurt to ask. > > One more thing any used the new LDOS 6.3(upgrade for TRSDOS 6.2) that is >also available? > YOU BET, It's a GREAT system and I have yet to find a bug. The timestamps are nice to have. I'm currently trying to figure out a clean way of manipulating time/dates in Misosys' C.

If you are running a regular 4, all you need do it boot up using a model 3 disk. Adam

The model IVP does not have these roms and therefore needs to read the rom image (MODELA/III) off the disk. By the way, hold down the break key when powering on the IV and you will go into model III "cassette" mode. Mark
harris@dg_rtp.UUCP (03/31/87)
Yes, I have LS-DOS 6.3 for the Model IV. Works fine. One doesn't need any prior DOS release to use LDOS 5.3 for the Model III. Go for it. Mark

When the 4 boots, it will No, thats only for a Model 4P. On a regular Model 4, you just boot up the model III diskette as if it were a model III. In fact, if you hold break and press Reset, it will put you in Model III Basic (non-disk). -- Andy "Noise" Andrews Disclaimer: The opinons expressed above are mine.

This is only true for the 4P - my mod 4 boots a Mod 3 disk all by itself - just fine. The 4P apparently doesn't have some of the ROM in the vanilla 4. -- These opinions are solely mine and in no way reflect those of my employer. John M.

It would be REAL nice if he did this so that I wouldn't have to figure out a way to convert from LS-DOS<=>Unix. Sigh..... If I do manage to write these routines, school keeps me busy, they definitly will be released to the public domain. Another back- burner project is adding a directory system, a 'la unix sort of, to LS-DOS. I'm wondering if it's worth my time to unbury my notes I scribbled down last summer about the directory system. The directorys would only work for non-SYS files. The overlays would still have to remain in the "root" directory. mkdir, cd and company would be seperate utilities to maintain directorys. Directorys files would use the DAM as the root directory so that one could ID a directory file just by doing a check of the DAM, look ma..no bits used to indicated a file is a directory! The directory system would install as a high memory module and intercept open,close,read,write,etc calls via the SVC table. The current working directory would have a drive and pathname associated with it so only one directory plus all root directorys could be accessed at any one time. I don't know if catching the SVC's would do the trick as far as insuring that the system would trash a disk. Any input from the net? Anybody know if my theory would work? I have very detailed ideas for this system sitting somewhere at home but they are burried deep inside my closet; where no human has gone before ...... Enough rambling for today, -Rob rhealey@ub.d.umn.edu

MODELA/III is needed only by the 4p which is not equiped with the proper built in roms.
