Hi everyone!
They don't get hot, but they get pretty warm here in the tropics.
And here is what I think: these are vintage chips, they will not be around for much long. According to Arrhenius law, lifetime is shortened at higher temperatures (there are some chemical reactions and physical processes slowly going irreversibly forward inside every electronic component).
I just love these chips and computer so much that I decide to make things a little harder for entropy to take them away!
And the heatsinks brought some personality for my beloved PAL-1!
Cheers!

I have never seen an 8-bit computer that had a CPU cooler, that's why I asked.
Below is a close-up of my board just after assembly.

NMOS like 6502 and 6532 get warm, not hot. Cooling is not necessary, never done it at 1 MHz, but it the will not hurt. Cooling the 7805 is advisable when yiu add extensions.

Ronny,
I see you've put heat sinks on the 6502 and 6532. Did they get hot, too? Mine don't get warmer than about 30 degrees or so during normal operation.
I will put a heat sink on the 7805, in preparation for when my expansion boards arrive.

This post is my "hello world!" to the group :D
I wanted to show you the solution I adopted to get rid of the hot 7805 linear regulator. I've found this small 78xx pin-to-pin compatible dc-dc converter on aliexpress and it is very inexpensive. It can take 24V input and output 3A max. Worked like a charm!
By the way, I would like to thank everyone for all the information posted here. It helped me a lot!
Best Regards from Brazil,
Ronny

Just assembled and performed the first tests. To match my software development the KIM Uno and the 6502 Microprocessor KIT (for which I am just trying to expand the monitor program):

I used my PAL-1 to help test a 6502 emulator I wrote - details here: https://github.com/GrantMeStrength/KIM1
I made a case out of acrylic and 3D printed some key caps too.

My current setup. Everything mounted on a Plexiglas, the PAL-1 itself is covered with plexi.
Above the Motherboard you see the raspbery zero running piGFX, on the bottom of the motherboard you see the dTR Tape emulator.
(sadly this does not work in combination with the tape interface).

The obligatory thread for showing off your completed kits and setup for the PAL-1. Also a great place to share building stories or ideas to inspire others.
I'll kick off with mine:
Inspired by an original KIM-1 that was attached to a piece of cheap plywood that is on display at the Homecomputer museum in The Netherlands, I decided to attach my PAL-1 to a piece of leftover floorboard - advantage: it doesn't warp!
Below is a picture of my PAL-1 ROM card connected to the ROM emulator designed by Kris Sekula (Mygeekyhobby.com).
Cheers,
Hendrik-Jan

In the mean time I got ESP-link on a NodeMCU board working, so now my PAL-1 terminal is WiFi connected :-)
