Hi Marcel,
Nice circuit board, are you going get the whole thing machine soldered, as manual soldering of over a 100 boards would be very tedious.

Of course. The bottom will all be machine soldered, the top may be hand soldered or not, we'll see. Hand-soldering would have the advantage that both Micro-SD and SD versions could easily be produced. Also, I still have literally hundreds of parts laying around

It mostly depends on the price increase really.

I don't have the means to program the chips before they're soldered in. Also, next prototype batch will probably be pre-soldered anyway (all except the flash as the prototype service I use unfortunately doesn't carry that part).

Ooooh. Someone slipped a 512K flash chip on there. Sneaky!

Not at all, I said from the get-go that it will hold 8 complete OS ROMs, switchable by software

Yes, there are switches on it that can make it work in different configurations and that is one that is supported. But to get the most out of it one should remove the internal ROM chips as QL-SD can hold up to 8 different operating systems.

It's so exciting to drop in and see so many exciting developments. Between Peter, you and Tetroid, everything is covered.

I think the size of the SD cards used as storage is relatively irrelevant - All of the SD cards I recently bought were both sizes (Micro SDs in an adapter). Accepted it's a bit fiddly to find the mislaid adapter just when you need it, but more relevant is the internal/external and 1 slot/2 slot layout.
I'm have been experimenting with SDIO cards like the Toshiba FlashAir for some time now, giving QL-SD access to WLAN and peer-to-peer networking - Those can generally be had as large-size cards only, so must be kept in mind as well.

So I purchased one of these:
https://www.amazon.com/gp/product/B078G ... UTF8&psc=1
I was able to use it as a plain old SD card adapter in Windows 7. I was also able to connect via WiFi and see the files on there. What I couldn't get to work is for vDrive to properly recognize the adapter with a formatted and filled microSD card (I had used the same microSD card I used in a non-WiFi adapter and it worked in that). So there is some incompatibility. I will have to try it with my Q68 next.
Do you have any insight here? Is there different classes of SD cards/adapters that some devices can't recognize or is this ezShare adapter just doing something weird? Or is it vDrive?

Any reason to think these will not be compatible with the JSU ROM/US Sinclair? Assuming they wii be compatible, I'm on board to buy the external version when it becomes available. Tom
