So I have actually had the latest PCBs for a while.. But with so many projects constantly ongoing it is hard to find time to work on this these days
I need to build one of these up as this has the I/O port for the fast ram boards is shown a couple posts up..

As shown in my
blog earlier, I just hooked up a previous version to make sure it was all working fine before starting a new build... The new build had some pins rearranged and of course the 4 SRAM IC outputs... Basically I should be able to get like 64MHz into fast-ram. I really want to see what the proper results are for this speed on a basic 68000 CPU..
One reason for the delays in this project was because the SRAM chips were incredibly expensive and the board would cost around £120 just to make... This is the reason I started a new topic about
porting the SDRAM controller from the TF330 to a new board, as it would be a lot cheaper to produce that way.. So I hope to make the fast ram as fast as possible, in the order of like 10ns, and make the board at a more sensible price. So while the booster has been around for a while, it could not really progress until the faster RAM board is completed..
In any case, I do have several of the original boards which are still untested, but I think when I build up hopefully the final SEC booster version I actually still working with one of these current fast ram boards... 64MHz speeds should be easily possible with this current setup.
