Interesting about the motherboard.

In my super early Space Invader Chickenlips, the PCB is actually more of a golden color. I didn't notice any revision numbers but will take a closer look next time.

My later non-mechanical Chickenlips motherboard is the typical green color.

Yeah perhaps they used different colors depending on the location of manufacture? I have some Rev 6s that are golden and some that are green. I think it is the same on my 2 A2000s. Both are Rev 6.2/6.3 but are different colors.

I am curious if you would agree with me that the keycaps on the space invaders chicken lips are not pad printed but rather dye sublimated. They are PBT plastic not ABS and do not yellow, and PBT caps are usually dye sub.

I can take some more pictures if you need them. I’ll peek at motherboard for the color as well.

100% agree. I've had a friend of mine in the SEA-CCC named Christian, who is also a member of this site now, talk to me about this very topic. Upon very close inspection I can confirm this. I have a DSLR with a fixed-lens macro and really got in there. These are definitely dye sub. As a result, they are actually a little fuzzy around the edges, but they'll never yellow or wear off from use.

I've also learned how to safely remove these keycaps, and they are extremely low-profile, which is pretty cool to actually see when you hold them in your hands. It's pretty wild.

Some of the keyboards from yesteryear are such achingly better than what I use in my professional life today. Heck my blue-tooth Mac keyboard (white) at work had half its letters wear off after just about 3 years or so. It's that old cliche: things just aren't made to last anymore! ;)

Yellow A500 motherboards are typically made by Kalox (I think - need to look). They also made some of the A2000 rev 6 motherboards. No idea who made the green motherboards. I think that the yellow motherboards are more "estheticically" pleasing...

well what do you know I found my A500 from 1987 bought from KMart in original box and all original goodies except mouse which I’m positive I still have somewhere in my mancave !
Same Commodore and Amiga key caps and yes embossed Commodore logo...the best damn keyboard I’ve ever used ! such a great sturdy feel..

just tried to boot her up and the dreaded green screen...so looks like i’ll be soldering some ram chips or new Agnus soon enough :-) still so cool to find her by accident today while cleaning out my old bedroom closet at my parents house today

1987? So not a + then, so probably green screen is battery leakage on the trapdoor memory expansion clock battery :)
