I wrote number of times that Amiga 600 accelerators can't be used in A500 or somewhere else and reasons are not just socket related DIP or PLCC, they are technical nature.
Hi Majsta! Could you give a few hints at some of the differences? Is it voltage regulation? timing differences? something more complex? Just curious..
VMA,VPA,E for start then some other stuff...

danwood_uk yes pre-orders are closed for now

khimru yes game rules changes quickly. Let me compare few things. On first version of the Vampire I could buy lot of parts in my own city for it, now it is nearly impossible to get anything because this is like 100 times complex than old vampire in every way,. Also demand is higher now and used parts are way more expensive than before. Last night I was soldering 60USD paid FPGA on this so imagine how much that cost in total when you have many pre-orders. The same time I was lucky that I didn't pay for single FPGA up to 120USD. And the same time I have bunch of those from Ebay paid 15USD who does not work. Imagine, from one shipment of 20 FPGA only 2 worked so it is really risky game i have reported on Altera forum in detail. You ask for replacement and then he send you bunch of others who does not work also. Bunch of fake ones, or damaged on JTAG side so even if you use higher resistor values you can't detect them. What about the parts who are left behind in process of changing design, expensive parts who will never be used. This morning also I had a call from DHL and customs and need to pay 27% tax on my huge shipment who is stack on airport and waiting for clearance. So all morning I was preparing papers and talking on the phone. This time and manufacturing this is not just a hobby game, this become more serious. At the end you realize that you are doing much more paperwork, going to the bank, customs then just designing or soldering.
