About two years ago I bought an A500 with embossed logo, red LED and a very early prod number hoping it was a hi-tek machine but alas it was not. Now I JUST bought an A500 with Hi-Tek keyboard but it does not have the embossed logo. Strange stuff! I'll post some pictures when I've picked it up :)

I just got a second Chicken Lips since my first one is currently, ahem, resting with a fault.

The new Chicken Lips has the embossed logo and Commodore Key, but it has a Rev6 motherboard - so definitely not an original motherboard.

At least I can say the rumors of the Hi-Tek Keyboard not working with newer motherboards is false (although I do not have a Rev8 A500+ motherboard to test it on).

I just got the Hi-Tek A500. The keyboard is the filthyest I've ever seen. This is how its looking after I've tried cleaning it with damp cloth and with alkohol. Its a lot better but I have to pull these caps. So far so good :)
Keyboard

I have to pull some of the tops of the switches to clean them. Some of them are SO sticky with some sort of gunk.

It also has an older motherboard then my other A500. And very different cables to the floppy drive :)

EDIT:
Ok, so this is quite nerve-racking. I've found a method that appears to work quite well. I'm using a keycap puller and I have to pull equally from both sides, and at an angle. So I'm pulling up and away from myself. This usually just releases the cap, but sometimes also the top of the switch itself.
When the top of the switch comes off I use a tiny flat tip screwdriver to lever the cap away from the top of the switch. It has worked so far. Many of the switches themselves are dirty on this keyboard. Sticky with gunk. So I might have to clean several of them.. Im quite tense right now :P

Edit 2:
All caps removed:
some switch-tops for cleaning, with springs resting close by.
I'm hoping none of those switch-forks suffer for this. I'm doing my best to be carefull. :)

This is how I learned how to remove the low-profile keycaps from the Hi-Tek "Space Invader" switches.


I only use this tool with this type of keyboard. A gentle side-to-side rocking and most of them just pop right off. Before I learned how to do this I would pull up on the keycaps and it was a total disaster, springs flying, etc. This keeps the Space Invader intact.

Thanks for the video! That tool looks right for the job allright! :) The one I've been using is the opposite! I'll have to get my hands on one of those. But for now I actually managed to clean this thing, and ALL the switches still work perfectly. I'm extremely excited about this machine. I managed to score this one AND an A4000 in one week, so all things are coming up *ME* right now :)

I don't know if this is the right place for it, but I'm having all sorts of strange surprises from my A500 now. First off I had issues with the machine freezing up when trying to open programs. I got to the bottom of it, there was an error with CIAB. With a new CIAB it was working perfectly, so I thought I'd put some 1.3 roms in it but then the machine wouldn't boot at all. Put the 1.2 roms back in and the machine starts but now it won't read disks. It'll take the disk and prod at it a bit but then just kick the kickstart screen back up. I tried the drive in my other A500 and it's perfectly fine. I then tried changing the other CIA as well. No difference.

What could be the issue, and why wouldn't it boot with 1.3 roms? The roms are fine, they've been living in my other A500 for decades.
