Will the TRS-80 emulator for the MAc ever be able to save games so that you don't have to start over from the beginning everytime you start up the emulator? Thanks.
I have a couple of programs I wrote on a TRS-80 Model 3 in high school (yikes!). They're saved on a 5.25" diskette. I've downloaded the emulator for my Mac, but can't figure out how to transfer the files.
They're just games (I think!) so I don't want to spend a lot with a conversion service. Any ideas? Can a PC with a 5.25" drive read these diskettes (although who has one of those these days). Any suggestions would be appreciated.
If you have access to a PC with a 5.25" floppy drive, it's just a matter of running a TRS-80 emulator (there are several) and copying your floppy to a .DSK file, which my emulator will use.
During development, I actually connected a Mac and a TRS-80 together with a serial line and wrote a small piece of Z80 code that read the sectors from a floppy and sent the data to the Mac across the serial cable...
Yves,
When I upgraded the emulator to version 1.6b2, it would no longer run at all on my Mac. I have a PPC G3 with OS 8.1. The emulator wouldn't start up. I re-downloaded version 1.5, which still works fine. Has anyone else had this problem, or am I the only one?
v1.6b2 timed-out on Sunday, June 6. This is the only reason why it's not running (it actually runs, but quits right away when checking the date). I'll be releasing the final version shortly, in the meantime, you can always set your clock back (sorry).
Every time I download the TRS-80 file I get is a trs80-16b2.sit file that will not decompress or open any futher. I've tried it on two different Macintoshes. What's up?
I've been trying to download games from almost a month, and if I do get through with a download succesfully the game will just turn to a text document, all I want is a game or two to play
GREAT emulator! Except that I did a lot of stuff via cassette tape.
Ideally, I'd love to connect a cassette recorder aux jack to the mic input of the Mac. And perhaps the ext. speaker line to the mic input of the cassette recorder.
Any chance?

P.S. I guess if this could be done, then sound output would also be possible...
Thanks to Yves for continuing to update his TRS-80 emulator!
Now maybe if we all beg him for added sound support then we can relive all those adolescent gaming years with better memory. What do you think Yves?
also, am I the only one or does the floppy not always work when the emulation speed is cranked up? I'm on a rev.A-233mhz iMac. An added routine that would try to set the emulator to the act around the original speed (2 mhz?) would be cool too. Mostly for games and such.
The sound is planned for version 2.0. The problem is that I have to rewrite the entire Z80 emulation code in C (it's in 68020 assembler right now) before I can add support for sound and spare time is in (very) limited supply right now. It'll happen, but you'll have to be a little more patient (also, it will be PowerPC only).
The problem with the floppy not working when the CPU is too fast is in the DOS, believe it or not. The DOS assumes a clock rate of 1.74 MHz and accesses the FDC at a specific rate (adjusted with timing loops). When the clock rate is increased beyond a certain speed, DOS is no longer able to communicate successfully with the FDC, which prevents floppy operations. In version 2.0, the Z80 emulation code will keep track of clock cycles, allowing precise clock rates (prefs such as 1.77 MHz, 2.0, 4.0, 8.0, etc...), sound and an FDC that depends on clock cyles and not clock rate (allowing DOS to opperate at any clock rate).

is it possible to use or borrow some of
the TRS-80 CPU/sound emulation code from
various other TRS-80 emulators made for
the PC -- i know of several that exist
for the PC that may have the code already
done. but then it remains a matter if they
are willing to share their code. :-\
I already have a couple different C sources for the Z80 emulation code, but nothing I can use directly. I'll have to write my own, but I'll probably re-use some of the ideas I saw in those sources...
I just created this forum to get feedback on the TRS-80 emulator. If you have questions, want to suggest anything or want to report a bug, just leave a message here (I'll try and check for new messages at least once a day).
