Raven060 (kodak80 build)

[kodak80]

Starting my blog topic to track my build and keep the other posts as intended.

Here is progress after a couple of evenings soldering.

I was having trouble finding the PGA206 socket, so I made it up with female turned header strips. Probably not the best idea as the CPU chip is now pretty tightly seated and did not want to come out when I attempted to remove it.

This is probably a bit better then strips I suppose. But it is definitely a snug fit in an ordinary socket as well.

Neat solution!

I ended up getting these from Archi-Tech in Poland

Hi,

Fingers crossed!

Okay, Raven060 board is now built. Only soldered in 1 ISA for testing as should only need an ET4000 card. I am waiting on the MC68510 chip to arrive.

1 x RAM module has its chips soldered on, just needs the capacitors.

And will look at programming the ROM, and other chips.

Eifel programmed with eiffel_1.10.1(Mq)_fixedFire_noLcd.hex - done
Iski programmed with A1 iksi_240418.jed - done
Narnia programmed with A1 narnia_240422.jed - done

All above chips were programmed with my T48 programmer.

If anyone else is struggling to get real 68060 PGA sockets and not too far from Switzerland, I've got 6 here (ok need to desolder them but that is easy...).

ROM now programmed with the last ROM shared.

Managed to get Coolterm working on Windows 11. I made these changes to the settings:

Serial Port section:
Baudrate set to 750000, data bits 8, Parity none, Stop bits 1
Under Terminal section:
Enter Key Emulation set to CR instead of CR+LF

Then connected to COM port.

E erased
I showed the chip information
P to commence programming

Then in the top menu under Connection, select "Send Text/Binary File..."
Select the ROM file and then watch it send with the progress bar. The Pi LED blinks as advised as it processed the file.

When completed transferring, a message shows the transferred size which corresponded with the ROM file size.

I have also soldered in the ATF1508AS JTAG 10 pin IDC socket.

Now to program the ATF1508AS chip…if I can remember how I have done this before.

So not far off completing the build now. Won't have any time this weekend to progress further but hopefully in a week's time will be powering the Raven060 up and testing things.

With regards to the SIMM and ROM SIMM. When I ordered the PCBs, I missed that these needed to be a certain thickness. A costly mistake when they are coloured black.

Thought I would mention it here to help others.

They need to be 1.2mm thick as noted here:

@agranlund I also wanted to check: I have ATF1508AS-10JU84 which are 10ns chips which are not 7.5ns as per the BOM. I am hoping that the speed difference will not cause any issues.
