    Thank you for your interest in the T2A2!

    As said on the T2A2 page, I’ll solder them on demand as I don’t know how big the interest is/will be. So here are the boring facts:
    • Price for one T2A2 card is 50€
    • You’ll need a so-called TRAM (a small PCB with a Transputer+RAM on it, described here, or an external Transputer system to connect it to the T2A2
    • To program the Transputer, you need to dig into either OCCAM or C programming using the INMOS tools
    As for the needed TRAM:
    I have created a Über-TRAM called ‘AM-B404‘.
    It’s a size-1 TRAM with 2MB SRAM… I’d say the fastest 2MB you can get.

    That’s a bit costly @ 60€ a piece (but still a LOT cheaper as what you pay on eBay) + 10€ for a T800 Transputer. I still have 2 AM-B404 available from the last batch. That said, 2MB RAM might be a bit over the top for an Apple II – at least as long there’s no application making real use of it.

    I.e. 2MB are enough to run a complete OCCAM development environment on it, or a complete Helios kernel with all bells’n’whistles.

    So for the first steps I might also have some (used/vintage) 32k & 128k TRAMs left, ask for a quote.
