trs80gp is a TRS-80 Model 1, 2, 3 and 4 emulator for Windows that runs well on OSX and Linux under Wine.
You can download it at http://48k.ca/trs80gp.html

There are quite a few changes but better handling of floppy formatting is the biggest. Here's a fairly complete list from my change log.

------------------------------------------
Numerous bug fixes in floppy emulation especially around formatting.

.cmd files now loaded under TRSDOS/LSDOS rather than ROM BASIC.

Sound mute menu entry and auto-muting paused or using menus.

Full screen and new sharp rendering mode. (perfectly square pixels with scaling)
See -vf, -vs, -vi command line options and new View menu.

Reassigned and new hot keys:
Alt-F5 - reset (also in File menu)
Ctrl-Alt-F5 - cold reset (also in File menu)
F9 - pause (also in File menu)
F11 - screenshot
Shift-F11 - clean shot (screen shot without beam conflict dropouts)
F12 - turbo mode while held
Shift-F12 - turbo mode (also in File menu)
Alt-Enter - toggle full screen mode
Ctrl-Alt-C, Ctrl-Insert - Copy
Ctrl-Alt-V, Shift-Insert - Paste

Disk files recognized by .dmk, .imd, .dsk suffix so can be listed without
-dN on command line. Or with just -d if suffix unknown.

Can insert unformatted blank disks with "-d dmk" and "-d imd".

Printer menu to turn off pop-up and turn off printer (also -poff).

Reset button and RAM badge added to soft keyboard.

Added IM mode, WZ register, EX latches and Z-80 instruction state to debugger.

BASICG and hires graphics utilities now on built-in Model II TRSDOS boot disk.

Handling of reset button and HALT instuction fixed on Model I.

Clock automatically set for Model 1, 3, 4 built-in TRS-DOS, LDOS and LS-DOS.

Added -is, -ics, -id, -itime, -im trackdump and -showframe for automatic input "scripting".

Add "Replace" to diskette menu for quicker eject + insert workflow.

Now have -m3n for Norcom emulation (99% just a different character ROM).

Bug fixes in screenshot when paused.

Beam debug now defaults to blue for conflict colour and shows the data that
would have been displayed if the conflict did not occur.

Display and beam conflict colours selectable on command line with -vc, -vd.

Built-in Model 4 LDOS now configured for 4 floppy drives (it had only 2).
 
@GP2000

Reporting a problem with your great TRS80GP vers. 2.1.0

Using Model II TRSDOSII v. 4.0.3
Trying to execute the FCOPY command to convert TRSDOS2.0 files to TRSDOSII files:

Drive :0 Mount TRSDOSII
Drive :1 Mount Blank .IMD disk
Drive :2 Mount 26-4104A.IMD (Graphic program disk)

Format :1 -> OK

@GP2000

Sorry, I forgot to mention a small irritating problem.

Some emulations, like TRSDOSII produce an irritating background humming, which cannot stopped with mute.
I hope you can repair it.
I know, turning off the computer sound solve the problem ;)
 
Great release! Especially the Model 2 emulation is wonderful.

I've got two feature request:
- Change the hardware models via a menu option. And possibly the hi-res and ROM options as well?
- A way to save (and load) configurations. I often use prepared virtual floppy's and harddisk's and it would be convenient to load a complete configuration.
The program works great on my Mac via CrossOver and these features would it make a ton easier to use any preferred configuration!

Thanks for the bug reports. Peter is looking into this one. Do you happen to know if this bug appeared in the previous release?

Well, obviously the problem is that TRSDOSII doesn't know the words. I'll install a lyrics module.

Ha, but seriously, this one is a bit odd. TRSDOSII does have a very uneven keyboard beep that is now on the list to fix. However, File -> Mute makes it go away.

Do you hear humming under, say, "trs80gp -m3"?
If you change focus to another window does the hum stop?
Are you running under Windows 10 or some other platform?

I'm glad to hear you're finding it useful.

Definitely features I'd like to see in some form. trs80gp's internals fight against changing the configuration in the GUI due to static initialization and the like but those problems might not be too hard to resolve.

Do shell scripts get you part way there? They certainly don't have the convenience of setting up a configuration interactively and you have to run a new one to change configuration. Still, they're pretty effectively a configuration file in most respects.
 
George & Peter,
THANK YOU. Just after I discovered that David Keil's TRS-80 Emulator does not execute in DOSBox any longer
under CP/M, you release a version that works well for the Model 4 running Montezuma Micro Ver 2.31. That saved
the day for me, as I was wanting to gather all the different CP/M floppy's that the Model 4 could access. I was able
to get snapshots of the different floppy choices, and thought I'd post them here.

ERROR 12
Click to expand...

Thanks for the bug report.

I get the same error when using TRSDOS-II 4.2 and it seems specific to GRPLIB/REL

Sorry, I don't have a fix yet. From what I can tell it isn't caused by the disk hardware returning errors but something internal to FCOPY itself.

I'll reply again if I find out anything more.
 
Looking at the TRSDOS-II manual it seems that SYS is only allowed when copying to drive 0

https://github.com/pski/model2archi...nd BASIC/TRSDOS-II_Reference_Manual_02-83.pdf

On Page 2/52 (about 70 pages in):

SYS - copies language and application programs.
If you use SYS, the destination must be the primary drive.
If you omit this option, only user files are copied.​

This command seems to work:

FCOPY !:2 :0 ALL SYS​

When complete, I could "GLOAD GPICTURE" or do "BASICG PIE1/GRA"
 
@gp2000

Thanks for the bug reports. Peter is looking into this one. Do you happen to know if this bug appeared in the previous release?
Click to expand...

In the former release it was not possible to format a blank disk with TRSDOSII.
I got a system error.

Do you hear humming under, say, "trs80gp -m3"?
If you change focus to another window does the hum stop?
Are you running under Windows 10 or some other platform?
Click to expand...

No the sound is only with TRSDOSII. It starts after entering the first digit of the DATE.
It doesn't matter if Keyclick is ON or OFF.
The sound stays if I change focus.
I'am running Windows 7. (I hate Windows X)
It seems to me as if the soundlevel of the generated TRS 80 sound is MUCH to high.

Did that list come from the MM utility? This entry is wrong:

Radio Shack TRS-80 Model 4 CP/M Plus (40T, DS, DD, 156K)

Radio Shack's CP/M Plus for the Model 4 was single-sided only.
 
Alphasite,
Good catch. It should be:
Code: 
Radio Shack TRS-80 Model 4 CP/M Plus (40T, SS, DD, 156K)

I OCR'd the PNG files and missed this one when I corrected the Document.

I'll double check the others to make sure they are correct.

It's from the "CONFIG" program on Montezuma Micro Ver 2.31.


Thanks.

@PNP2084

Looking at the TRSDOS-II manual it seems that SYS is only allowed when copying to drive 0

It solves the problem and FCOPY is working like it should.

No the sound is only with TRSDOSII. It starts after entering the first digit of the DATE.
It doesn't matter if Keyclick is ON or OFF.
The sound stays if I change focus.
I'am running Windows 7. (I hate Windows X)
It seems to me as if the soundlevel of the generated TRS 80 sound is MUCH to high.
Click to expand...

The sound persisting when focus is lost is quite baffling. The operating system itself silences audio so nothing should be heard. I've been unable to reproduce the problem. Here's something to try which isn't too difficult and will narrow down the possibilities. The idea is to have ordinary TRSDOS 2.0 click the speaker and see if that induces hum. Here's what to do:

Run trs80gp -m2 -time frame

Enter the date and time and go into BASIC

Enter this basic program and RUN it. You can copy it to the clipboard and use Edit -> Paste to do it easily.

Code: 
10 DEFINTU:I=0:U(0)=&HD37E:U(1)=&HC9A0:DEFUSR0=VARPTR(U(0))
20 ?USR0(1)
30 FORI=1TO100:NEXT
40 ?USR0(0)
RUN

You should hear a brief beep. Now to the questions:

Was there any hum? If so, when did it start?
If not, does running the BASIC program again trigger it?
There are two numbers in the title bar. About what is the number on the right that changes less frequently?

I'm hoping there is no hum until the BASIC program induces it. The frame time should be about 16.66 or 16.67 ms. I'm guessing that emulator speed might be a factor here.

Thanks. Might be a good idea to send me some e-mail (george -at- 48k.ca) so we can get into more depth.

P.S., If you like, send me a recording of the hum. There may be some clue there.
