What does that mean specifically in terms of compatibility regarding EMM386? Is standard Tandy not supported at all with EMM?

What Games support 01E0h ?
i don't know any.

Could the TSR be made to also support forwarding 0C0H to 2C0h to support the Tandy Soundcard ?
i also think i can send you a card when its ready 😀
this might come handy, due to the card can not listen on 0C0H on 286+.

Does JEMMX work with 0C0H ?

Standard Tandy won't work with EMM386. You'll need to patch the games or switch to QEMM.

I don't know. I haven't started on a JEMM version of the driver yet. JEMM's documentation is very fragmentary, there's no way to know without testing.

Some Sierra games have a driver for these "new Tandys". But that driver has machine checks and it also looks like it tries to use the Tandy DAC, so it won't work. I don't know of any other games.

Sure. That's easy.

So I take it as there will be a TSR package available in the veins of the adlipt package, with a patcher and a TSR?

Is this your experience or are you just making an assumption?

Yeah, a TSR is already under test and seems to work.
No patcher yet, but it can be done (especially for sierra games).

Hum, for the lo-tech Tandy Clone sound card, I modified TEMU to redirect C0h to 1E0h or other ports, and that seemed to work fine. I believe it sets up its own v86 environment. It should be easy to replace my redirection code with code for TNDLPT, then we'll have a TSR without this problem.

yeah but temu has plenty of incombatiblities.

Does not work on:
Sanyo 386 Laptop - 386SX20
Escom Blackmate - 386SX33

it loads the tsr, and after 1 or 2 seconds system looks up at command prompt.

>Is this your experience or are you just making an assumption?

Yeah resource conflict.
it may work on a 286XT but not on a AT Machine.

My K6 will only boot with 2C0 set on the Card.

CuteMouse 2.0 Alpha 4 does the same thing to me on my Packard Bell Pack-Mate 28 Plus, but version 1.9.1 and 2.1 Beta 4 works.

It works on my 286 AT.

new prototype

looking good!!!!

I 100% love the volume wheel. it feels so period correct.

is it the same as the ones they advertise for repairing gameboys?

A bit off-topic, just out of curiosity.
What kind of EDA do you use?

It works on my 286 and on my 386. Granted i have no hardware inside that makes use of High DMA. The only downside is increased noises coming from the card, compared when using the card on an XT.

Did few tests, it also works on my 486 ISA, but not on K6 and Pentium, also does not work on my 486 PCI System.

@dreamblaster
Nice,i like the pot on the TNDLPT =)

Did you choose Resistors and Capacitors for the Input Stage of the Amplifier to match the original Tandy ?
Somewhere i saw the schematic of the Tandy Amplifier Board. 😀
EDIT:
Found it.ftp://ftp.mindcandydvd.com/pub/drivers/Tandy/ … ence_Manual.pdf
Site 81 shows the Amplifier.

Lo-tech uses 470nf for Output Capacitor, you use 47uf.

And here is the Tandy 1000EX:

Yay for Open Source!

the next BIG stuff should be an all in one device:
- Covox (stereo)
- OLP2LPT
- OPL3LPT
- DSS
- TSS
and switchable per software so you can "configure" the device in a batch before starting the game 😀

In addition, it would be really nice if some of these modes could be combined and used at the same time. So one music device (TSS/OPL2/OPL3) together with one DAC device (Covox/Stereo-on-one/DSS), all on a single parallel port. This would allow machines lacking both available ISA slots and built-in Sound Blaster compatibility (such as older laptops, Microchannel PS/2 systems and later PCI/PCIe-only computers) to support both music and digital audio in many games, even if they would require some software emulation and/or patches to make it work with most existing DOS games. I recently started a separate topic for that: Multiplexing multiple sound devices on a single parallel port? (OPL2LPT, DSS, etc)
