Edit: sorry missed your question regarding which USB spi in cd32 thread. Answer: guess I was looking for a cheap and easy one off eBay but ardunio nano will be suffice as long as it's discreet and easy to integrate into UAE im game .
Make sure you get a TF530 Rev 3. The Rev 2s dont have the interrupt pin.

I got a rev 3 in black from you November ish

Edit : .

Bought an a500 rev6a mainboard today and USB keyboard adapter.
Bprepared is borrowing me a cpu and should have the tf530 built as soon as A week or so maybe.

I will get the a1200 going with spi cpld sooner( if it works out)

And arduino nano on order just now .

Looking at 3v3 modules ATM

Cool. Im gonna throw my MMC module and an arduino nano in my suitcase. If i can find my ENC28J60 module i'll take that too.

I'll grab both ethernet and a sd spi module on eBay now then . What mmc chip specifically you got ? And good plan, thought you would have let's hope others chip in, would be cool to have an array of options such as Bluetooth, Wi-fi, LCD/OLED/COLOR-TFT display, dot-matrix (think arcades), flash memory, nixi tube.. Endless applications of use

Edit: Is it possible to run multiple SPI modules (dreaming here a bit) in regards to cpld firmware/ hardware limitations? I think I read somewhere about this, but not sure if you can chain them.

Edit #2: so far I can only find expensive 30GBP MMC. Grabbed the most common cheapest SD SPI that has a 3.3v reg & 'SN74LVC125A' bus buffer gate.

The MMC chip? the SPI chip is wired straight to an sd card.

I'm gonna use this .. which by the way might let an arduino be usable for JTAG too..

Ah my bad so wont matter then. Good catch! it would certainly make an Arduino a very cheap jtag indeed.
