Old Altera flex10K, looking for a board schematic

[legacy]

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

Would you have the type designation or a photo of the development board?
Is it the one used here (figure 10)?

These guys show an “electrical scheme” for their eval board. Almost too simple to be true/complete?

This board had a sort of built-in byteblaster, which uses the parallel port of the computer for programming the fpga. It's currently removed, and I am directly interfacing the jtag.

I am not looking for the schematic of the board I specifically own, I am looking for a simple schematic for the minimal setup around Altera flex10K.

Seems like each pin is provided on the silkscreen. Why do you need the schematic?

I believe the Atera UP and UP2 CPLD dev boards had a Flex 10K... there will be schematics somewhere on the interweb...
... but there won't be much to them.

There was a book and a set of tutorials for the UP board somewhere.

to copy the decoupling stuff (on the the sideB of the PCB)
Besides only a part of pins are reported on the silkscreen.

the final purpose is creating a new board, to be integrated in a project where I need to deal with 5V devices.
