The TRS80 model 4 has its internal speaker hanging off bit 0 on port #90.  Runs at 4Mhz; far better working with than the more challenging model 1 @ 1.7Mhz.
Hoping that I have done some justice to Shiru, Utz, Tim and the few others of their engines & tunes that are up and running .

Just need to skip the first few minutes of the self promotion stuff.

I have looked and looked but I couldn't find this listed or shown anywhere in any of the sub categories. So, apologies in advance if this is common knowledge; can go ahead and delete this post if its kinda useless.
However, I thought that it might be worth having floating around for referencing.

All,

The Sam Coupe was one of these lesser known Z80 based computers, being released in 1989 and discontinued in 1992.
https://en.wikipedia.org/wiki/SAM_Coup%C3%A9

Its AY port is 511 & 255, whilst its beeper port is identical to the ZX Speccy: bit 4 on port #FE.
Asm orgin for the Coupe is at #8000

Loading the binary is the difficult part when you don't know how to.
Requires to load the binary into a disk image, then load the disk image into an emulator , or using another tool to write the disk image to a real Coupe 800kb floppy drive.

Timing is right off, as this computer runs the Z80 at 6meg. Slowing things down to a reasonable listenable tempo, still makes all tunes sound like that they have been put through a Phaser. Twice.

At the BASIC prompt , either in an emulator (Sim Coupe) or, real hardware with disk image access:

LOAD "file" CODE 32768

Have converted a bunch of various players over and experimented with speed / tempo. But none are really worthwhile in showing here.  Indeed the Sam Coupe will play them all as a cool proof-of-concept, but requires far more expert-level work to making them sound nice.

I probably won't contiue fiddling with this computer, as I know that its far beyond my knowledge to get the tunes sounding nice - time to move on to another, slower, 8 bitter.

"Let's Go" running in 'Jynx', a Lynx computer emulator.

Sounds great!
I will plonk the LYNX .TAP file up on to my github sometime.  Tap file auto starts within the Jynx emu.

At a guess most other engines should also work using the very minor changes.

origin    $6500
bit 4 port $0084   

        device zxspectrum128
    org $6500-13                ; Origin
tap_b:    db $22,"NONAME",$22    ;name             
    db "M"                    ;type             
    dw end-begin                ;program length         
    dw begin                        ;load point       
    org $6500
begin:
...
OUT ($84), A
...
end

tap_e:    savebin "letsgo.tap",tap_b,tap_e-tap_b

Been playing around a little bit experimenting with the Jupiter Ace.
The speaker sits on Port $FE, however it is set up a bit differently requiring a read and a write.

> Jupiter ACE I/O Ports
>
>Port FEh Read (or any Read with A0=0)
>  0-4  Keyboard Bits
>  5    Cassette Input (EAR/LOAD)
>  6-7  Not used
>Any read from this port toggles the speaker "off". Speaker IN.
>
>
>Port FEh Write (or any Write with A0=0)
>  0-2  Not used
>  3    Cassette Output (MIC/SAVE)
>  4-7  Not used
>Any write to this port toggles the speaker "on".  Speaker OUT.

So, something like:
   out     (0),a        Speaker Out
   in         a,(0)        Speaker In

So far everything has been a fail for me, but, I enjoy the fiddling around & experimenting.
One of these days I'll crack it and get something (anything) to work.

Hi all,

Few months ago I uploaded my little collection of all collected 1Tracker .1TM module songs.

https://github.com/bushy555/1tracker_1TM_1-bit_songs

I have intentionally left out all of the test examples that are within the TEST sub directory in 1TRACKER.

Any other known full .1TM tunes that have been released?

Cheers!
