Ask @pakman over atari-forum.com for the lasted GAL Files and there are some Hardware Patches needed ...

And just to balance everything out, for anyone who might need it,
here's the latest Pak TOS version that I got from Holger Zimmermann.

For the US, patched to make it boot up into NTSC/60khz, instead of
PAL/50khz. It was driving me crazy on my RGB2HDMI mod and not
being able to figure out why I couldn't get it to boot into NTSC.

I patched the tos306 ger with Markus patches !
thank you

but anyone has these chips for the pak68? Tag Ram 2xMK48S74N-20 or 2xMK48S80N-20
Nothing to become. Only a mainboard with tag rams MK48S74N-20 in Canada? ca 140€
110€ shipping to germany ?????

I have this 2 chips. IDT71B74S20Y But smd type. I use an adapter from smd to wide 28pol. But this is very high and frak2 doesnt fit

Anyone has these chips?

Tag-ram is pretty hard to find and 20ns for that matter. But I sent you a PM.

Between PAK and FRAK you can put additional sockets in between to get the right distance ...
