So, I have an old Altera flex 10K, the chip is an old
EPF10K10L84 (wow, it's removable, I like it!), mounted on a small board with just headers and the jtag port. I still have Altera QuartusII v5 installed in my old Windows XP laptop, and the software is able to see the chip via usb-blaster, and it also seems working.
WOW, perfect, nice, excellent, awesome
What I'd like to do with this? Well, I'd like to replicate the fpga board in EagleCad in order to make an expansion board for my 68K board. This seems easier with Flex10K because chips are 5V tolerant.
OK, bad news now: the board is all made in smd and it doesn't have any documentation, and there is no schematic, not even a piece of paper with something on it. Nothing at all!. It's a very simple circuit, FPGA, oscillator(1), decoupling stuff(2), headers, and jtag pins, plus a power block, but I'd like to see a working example.
Anyone?
edit:
(1) 50Mhz. OMG!
(2) this is what I find difficult to design by myself
