If you're in the US and interested in one of the semi-complete boards, see my post here. I've got 6 left.

I can grab one as a spare. As a newbie member, I’m not able to msg you. 🙁

If you read my original post (linked from the post you quoted) you'll see there's a Google form to fill out. Once that comes in I'll send you an email with info.

For every TinyLlama 2.1 owner who already has a small wavetable board or can't get hold of a pi zero 2, I'm happy to say that the Pi+wavetable adapter board is currently in production! 🎉
It'll be 100% assembled and ready to go.
As promised, I'll sell these at cost, which turned out to be almost exactly $10 per board.
If you're looking to get a wavetable board, check out Serdashop.

I'll post updates here when I get the boards delivered in about a week.

Great! I will grab one of those OFC!

So I did a test installation of XP on my tinyllama2 today.

A couple of things I noticed.

I confirmed that the SD card interface is the same RDC interface that the WeeCee uses (and that windows 98 seems to hate for some reason)
Which means we're limited to 32 GB SD cards.

On the plus side, since the tinyllama2 has a serial port I can have a go at remote debugging windows 98 now on my other 98 PC, maybe I can get some insight as to why ESDI_506.PDR dies.

I also noticed that XP's WDM audio driver doesn't like this chip for some reason.
I booted back into DOS to confirm it's working so I'm not sure whats going on here.

Do you mean that under WinXP the SD disk works with higher speed as expected and without temporal system freezing?

How do you debug win98 via serial? I though that serial debugging is available only on NT systems but didn't play much with it.

Yeah, SD is a bit faster and no freezing on XP.

There are debugging tools in the 98DDK - WDEB98 and RTERM98
I'm not at all familiar with these tools to be honest, I hope there's a guide available somewhere online on how they work.

I can talk about my experience. I tried to Install Windows 98 SE on my TinyLlama, and the system froze after installing storage drives. You need to disable the device to make Windows 98 work. So there is no acceleration or DMA. I don't know if DMA is even possible on this interface. In the end, system performance and copying from and to disk is poor, and in many cases, when you need to issue multiple writes, the system hangs.

Yes, it's obvious that if storage runs in PIO mode it causes high CPU load and poor bandwidth. Also on normal PC, even with fast SSD the PIO is ten times or more slower than DMA. Also SD card may have some random delay during data write and if there is some ready flag polling in the driver it may hang system for several seconds until flag is set and loop exits. But it shouldn't affect read performance, it should be much faster than writes. For better write performance some industrial grade SD card may help...

If there is ever a future revision of the tinyllama2 I'd recommend using one of those 'SD to CF' translation chips that you see on SD to IDE adapters on ebay for some improvements in disk I/O performance.

That or an MSATA port.

Yes, if SATA is still available son SoM pins, it would be good to have a mSATA connecor. But does it support IDE compatability mode? Is BIOS ready to boot from SATA?

I would be very surprised if the BIOS can't boot from SATA, it's a SeaBIOS so it should.
Whether it's in IDE or AHCI mode is done at the controller chip, we know it's in IDE mode already so we're safe.

edit:

I figured out the sound issue on XP, XP gave the wrong resources to the chip, a manual edit to reassign resolved the issue.

w00t booted my TinyLlama and nothing blew up! Successfully flashed the BIOS.

Got the wavetable adapters in, they work as intended! Tried with both an S2 and an X2GS board, no problems.
Using this adapter makes the whole setup a bit more chunky, as seen on the photos below.

In order to install this adapter, the following steps are needed:
1. Only works for the TinyLlama rev.2.1. The rev.1.1 board has its DAC placed slightly differently so it won't fit properly.
2. Desolder the purple GY-PCM5102 board from the TinyLlama.
3. If the pins on the 3-pin header on the TinyLlama that was connected to the DAC were cut, you need to desolder that as well and replace it with a fresh 3-pin header.
4. Solder the DAC back on the adapter board.
5. Insert a Raspberry Pi Zero 2, a wavetable board, or both, on the adapter.
6. Place the adapter carefully on the TinyLlama, making sure that both the 40-pin header and the 3-pin header line up properly.
7. Use the switch to toggle between the Pi and the wavetable board. Whatever device is _not_ selected is powered down.

Send me a mail at ordertinyllama@gmail.com if you want one, they're $10 a pop + shipping of your choosing.

Superb! I would like one please, sending an email. My setup would be exactly the last photo, adapter plus X2GS with no pi zero. Thank you!

Could you just solder second GY-PCM5102 to the adapter board and leave the other GY-PCM5102 in place?

In theory, yes. But the "old" GY-PCM5102 will block the connector carrying the analog audio from the adapter board to the TinyLlama.

Cool! I should add - if you're only planning on using the adapter with a wavetable board you don't actually need the purple DAC board at all - that's only for the Pi.

I see. I will solder it anyway, just in case I add a Pi in the future. Thank you!

Has anyone tried Monkey Island Ultimate Talkie Edition? My TinyLlama freezes as soon as Guy says "Hi". Searching around it looks like it happens to folks with certain mouse drivers but I'm not using any with the Llama.

Edit - For anyone else experiencing this, I figured it out. UniSound by default assigns IRQ 5, if you use SET BLASTER, specify I7, and then run UniSound to force IRQ 7 the game will run without freezing.
