I didn't use a ramdisk. I think your ramdisk is the problem. MEMSAV in MyDOS
4.53 load TBXL 1.5, N option loads TBXL 1.5. Then DOS/DUP.SYS gets back
to 4.53 menu, then M at 2080 works. I guess I don't understand the problem.
I'm working in atari800winplus 4.

Excellent, Russ! You have solved my mystery!
I have always used the regular MEM.SAV file -- 58 SD or 29 DD sectors as the mem.sav for this exercise. You use the actual TBXL as the (binary load) MEM.SAV. Sure enough, when it goes to the DUP.SYS menu and I use the "M" at $2080, it loads the part that gets clobbered and works perfectly. Evidently, I never understood how the MEM.SAV was changed from the earlier versions (3.07, etc. that were like Dos 2) to be more flexible like it is now. I don't think the manual is all that clear about this, so I'm definitely going to put some notes in mine. BTW, this works for either real hardware or Atari800WinPlus4.

I agree Excellent. Thanks 'Russ'.
Larry, have you ever used MyDOS 4.51 or any of the newer versions of MyDOS. I just wonder why you keep mentioning 4.50 version.

I have tried some of them, and for one reason or another, I've always gone back to 4.50. Guess it's like a comfortable old pair of shoes. However, I don't recall ever seeing 4.51 or 4.52. What was fixed or improved? IIRC, for most of them, they kept getting a little bigger with each revision. (?)
4.53 seems to work well, and 4.55 beta 3 seems fine. Do you have a particular reason for liking 4.53? (IIRC, you mentioned before that you mostly use that one.)

I use Diskcom to enlarge this type of DSK or Imagic by APE 'classics' software. Just rename xxxxx.dsk to xxxxx.dcm and drop it into the window of Imagic.
In looking at the MyDos 4.53 files, the author included a .DSK image. (Apple and TI and ST?) Easily handled by copying the files to an ATR, but I was curious if there is a conversion tool to change it to an ATR? Just looking at it quickly it looks like a "short" XFD. BTW, APE can be a little picky at times, but it readily accepted this DSK.

Also there is an Older dos program call DCM2ATR.EXE that did this back in PC DOS or WIN95 days.
