SysInfo reports 3.29 MIPS and speed 2.59 times higher than a stock A1200.

The CPU core is clocked at 14.18 MHz but it's being slowed down to 7.09 MHz whenever it wants to access memory bus (and it wants it almost all the time so only multi-cycle instructions like multiplication, division and shifts/rotations operate any faster). It will change when there is a cache implemented.

Also the CPU core has only 16-bit wide data bus so the performance could be improved in the future by implementing direct long-word transfers but it entirely depends on Tobias.


I think this implementing cache and the wide data bus is more important that dual cores at the moment. Finish the job on what we have before starting a MAJOR job like dual cores.

Can't wait to see it available.

Makes me want to get the A1200 out of storage and working again, hopefully it hasn't sustained too much water damage when the roof caved and was repaired! Of course I would have to hide it in the barn, no more computers in the house! the wife says!

PS/2 connectors... awww crap... I think I threw away all my old PS/2 keyboards and mice... I thought USB would see me through :( at least there is a DVI connector (I only have DVI monitors here now...)


I notice most of the Amiga stuff uses PS/2 instead of USB, is PS/2 just a standard serial port where USB is a complex serial port?

Finally found mikej's posting on pricing back on page 40!!

Replay RevB Pricing.

The exchange rates are all over the place, and until I get production scheduled and the boards in my hand these prices are subject to change.

The NRE costs for production are much higher than I expected, so I have to recover some of these costs over the first 50 boards.

So, the full card (with SVHS/Composite out) is looking like 220Euro today. The "light" card without SVHS/composite is 200Euro. Thats about the same as a Minimig with the memory upgrade, and what I've been saying all along.

The bad news is I have to pay sales tax here on the first boards, so thats an additional 25%. I'll include a EU plug power supply for the first 50 boards :)

Being totally honest up-front, boards after the first 50 will be at least 25% cheaper and sales tax will be payable on import if you are outside the EU so thats another 25%.

From the quotes I've been getting from China we should be able to get down to 150 Euros for the fully loaded board for production quantities, assuming there is enough interest after the first 50.

I have all the parts for the first 50 so they are going to happen for sure, after that I'll set up a list - if we get to 50 or more we'll do another run.

I'll mail all of you who have expressed an interested with a firm price when the board is finally ready for shipping.

Let me know what you think.

Sounds reasonable to me...
