HYDRA SRAM complete
![AndreL](https://forums.parallax.com/uploads/userpics/141/n2HIHMVK7J31M.jpg)
The 512K SRAM is complete, sending the boards out this week for manufacturing, so we will start selling them in 1-2 weeks. We might even allow pre-orders, not sure yet. Still working on the final price from $39-49, might start out at $49 then reduce to $39 once we get more sales to build a larger lot. We will see.
I am doing the documentation right now, currently there is·a ASM driver, SPIN driver, test program example. If I have time I will do a graphics engine that uses it if I have time. But, with the examples, the test program and the drivers, anyone should be able to do whatever they want with it.

Are you selling those thru· Parallax or thru your site?

So bottom line the first 64K is absolutely the fastest possible access, all the memory is accessed in auto inc/dec mode for block access, but to get to any location after the first 64K, you have to walk to it. But, the trick is to use the upper 64K > as block memory for contiguous buffers and the lower 64K for random access areas.

Sounds good.
I hope that I can buy your card soon [noparse];)[/noparse]

Is it hard to modify the drivers for other pins?
Because I'm thinking about a robot.
Some ram would be good to store and work with information from sensors and so on.

When you estimate the board will be for sale?
I think you said a couple of weeks or sooner?
