I wonder if any registered members of this forum have ISSUE1 and ISSUE2 motherboards. A "group photograph" of them would be needed.

Thank you!

What happened with the heatsink cover?

can you see the monitor connector pins?

If I am not mistaken, all pins are present.

Did you buy it from the sold pack to Sovietunion, or did you buy it later?

I have hungarian manual. It was very heavy to learn BASIC on it.
