Hi,

Jan Knipperts is working on this one, just drop him a Message.

His mail is on github (if you have account)

Here is also alternate Driver for TNDLPT:
https://github.com/JKnipperts/TNDY

Has some flaws but does not require EMM386 or QEMM etc.
If you run with 1Mb RAM Machines you will have more spare Memory left..

Thanks,
GitHub means source is available, so I will find the format in the core.
Anyway I suppose nobody use it for the moment.

It can be great if IT can import /Export to .MON format, then, Trixter will no more have to support/Extend monotone anymore.

Final version of TNDLPT enclosure.
White + black is best match for tandy stuff ?

oh I like it!

Here's a video of the test rig, for 100% testing of the soundchip for TNDLPT kits

Nice video by pc-sound-legacy, showing soldering of TNDLPT while playing some nice TNDLPT game soundtracks

The Planet X3 update package with native TNDLPT support, among other things, is currently awaiting approval and will most likely be published within the next couple of days.

It omits automatic un-muting for technical reasons, but that should not be a big obstacle.

... And it has been published.

Hello, I'm curious what's the difference between the method above and disabling the mute circuit as shown in tndinit.c? Is one method better than the other?

Tracker for TNDLPT released :
TNDY Tracker - Tracker Music with SN76489 - Tandy 1000 / Tandy 3 Voice ISA Cards / Tandy / TNDLPT Parallelport Devices

I've uploaded the most recent patch i did for Tandy sound on non-Tandy machines to ftp.oldskool.org, the same repo that holds mine and others Tandy patches. The EGA 16 color version of Indiana Jones and the Last Crusade, unlike following Lucasfilm/Lucasarts releases, did not have a commandline switch for Tandy sound. Instead the Tandy sound code routines were tied to the Tandy machine detection. So i forced the code to always lead to Tandy sound, while still being able to display CGA or EGA.

I patched this with the help of a Serdaco TNDLPT + TSR. I haven't yet tested this on the lo tech Tandy sound card, but should work the same. I'll upload the binary here so you won't need to download the whole repo.

Awesome. Thank you!

I've been trying to patch the first Arkanoid game, the Taito version. It supports Tandy but it is tied to the graphics code. However it seems possible to actually patch it for Tandy sound + EGA, i managed to force the code to follow the Tandy sound routines instead of the PC Speaker ones. However although the Tandy sound plays its all wrong notes, this must be due to the data being sent to the SN76489 being suitable for the PC Speaker only not for the Tandy.

All is needed is to find where the data is read and written to, or take the Tandy graphics route so the sound data is properly put in variables and then somehow force EGA, unfortunately i'm at the limit of my abilities here.

Nice work, and thank you for doing !

Did you manage to get Alleycat running with Tandy/PCjr Sound ?

No, i thought that one had already had a patch.

With Arkanoid, i'm just at my limit, i don't think i can finish it. I might be missing something, i really need help figuring it out. Someone with both graphics Tandy/CGA/EGA and Tandy Sound ASM familiarity.

Thanks a lot for all those patches!

The patch you are referring to are probably these by bjt and NRS. While I was able to patch the executable successfully (on a 386+), I was not able to run it on a 286 with a VGA-card and the TNDY-card from Matze (I guess it switched to tandy graphics, because my display was not satisfied with the signal it received). However, both authors stated it should work with VGA, though maybe that is VGA in a Tandy machine. Maybe I am missing something or I have to try it on another system.

How about Skate or Die? Scali made a video showing a patched version of the game on an IBM 5160 with CGA and Tandy sound. However, to my knowledge the patch was never released.

Yeah i think i remember that one, i don't remember if i have the file around, but i'll check on my 5150.

Skate or Die, Kings of the Beach and Ski or Die are cool titles, but seem to only use Tandy Sound on the title screen music. The rest seems PC Speaker only.

Other games might just be impossible to patch due to a set of different executables for CGA, EGA or Tandy. This was common because .COM files share code and data within the same segment, so it was Impossible to do everything on one file only. From then on .EXE files were used the most.

Arkonoid is feasable to be patched since the Tandy Sound routines are there inside the same file. It is possible to patch, but i'm really at the limit of what i can do and its really looking for a needle in a haystack. I can force data to be sent to the Tandy Sound chip but i haven't yet identified where in the program that data is set for PC Speaker or Tandy. So what happens is that Tandy plays wrong notes. And i can do the opposite make PC Speaker play Tandy data which will Sound wrong too.

Need to find someone willing to help me out with this, because it seems that it can be done.

I've done it!!!

It was indeed what i thought it was, but i somehow missed the code. Using a debugger really helped, while i was tracing into instructions music started to play. Isolating that code and checking that subroutine on IDA. As soon as i saw the subroutine it was an eureka moment for me. Tested in dosbox and in real hardware, of course with the Serdaco TNDLPT.

I will upload the patch tomorrow. I'm tired, spent way too much time on this crapola.
