Sure, sourcing parts is no problem! PCB plus Interwave is fine.

Bad news everyone! Slight delay with the production, as the first audit "failed" due to the producer being unable to exchange one of the gerber files.
On the positive side ... there won't be any annoying visible "pool marker" on the board.

EDIT: Never mind ... seems like they went full speed on the audit this time and sent the board off to production already after re-ordering.
EDIT2: PCBs are being shipped 😀

Great news, I hope there will be enough cards for everyone, I joined this forum just to follow up with the development of the gravis clone, I never thought you will go this far!

Good news everyone!

Bad news everyone!
JLC PCB fucked up the instructions, meaning the cards ended up with the pool marker being visible when the card is fully populated 🙁
Even worse news everyone!
Shipping will be a bit delayed ... probably after easter. I'll PM you once your board has been shipped.

I don't really understand what you mean about the pool marker being visible, but they do look really nice regardless. I guess this means we need to order some components so we can build and test these cards, is there a spreadsheet or parts list thats up to date?

JLC puts a tiny text (like a serial number) on the PCBs, to track quality complaints and such. I never minded them before, but if you don't want them they need to silkscreen them where e.g. an IC will be placed.

Yup, that's what I originally set the "JLCJLCJLCJLC" marker under the main IC for ... sadly looks like they missed or ignored it.

On another project I've gone as far as scrubbing it off with a fiberglass pen and re-sealing the PCB with some UV-cureable solder resist with mixed results (south of the large FPGA): https://i.imgur.com/BSRqvHy.jpg

Also thanks for reminding me to upgrade the parts list ... it should be the same as for prototype #2 except for 2 more 10k or 0 ohm resistors and the additional 2x5 header for ESP/SPDIF.

I don't worry about the JLC marker , in fact I can say I don't care about it being there
looking good shock___ !

You can tell them to put the marker to a specific area. An aquaintance suggested putting the message into the gerbers themselves.

Which is exactly what I did ... after they cancelled my original order, so I could add it again. If they said "better luck next time" I'd have been ok with that. Now I have 2 markers and ended up with a 3 day delay. Meh.

Wow!

But these are still just beta boards so no big deal. Things happen. Not like it is going to affect the functionality in any way.

On a few boards, I actually scraped very carefully with a sharp, stiff blade. When the deed was done, you could hardly tell that anything had been there, and there was very little observable effect on the solder mask.

When dealing with smaller boards, you can save a few dollars by creating your own panels. I did that with one adaptor board I used for my early ROM module experimentation. I got 20 of them for the same price as five, and the marker was placed on the break-off tab above the usable boards. Now that I've done that successfully, it may be a way to cut costs on future ROM module production.

I`m pretty sure they will work perfectly as the last prototype did 😀

You are correct ... just assembled one board: https://i.imgur.com/a2okbvq.jpg
Only did major testing so far (output via demo/xtc-play, RAM test, ROM dump + checksum), but looks like no new issues were introduced. Meaning the design is final unless something severe pops up.

EDIT: Updated partslist will follow tomorrow.

We'll have to pay special attention to the 4-MiB ROM bank again. I suspect that the resistor changes will fix the problems with the previous prototype, but I'll only be fully convinced when I hear it.
