Ah, thanks. Obviously I misread the datasheet. But if one of them is low, how do CIA know when a key is pressed? In the info I could find it says that the CIA sends a bit on PB while reading them all on PA and if they mismatch (FF != FF), a key is pressed so CIA will scan / decode it. PB =...

I'm measuring around in my C64 and found a weird thing. The keyboard connector pin 20 (COL7 / PA7) is constantly low (with the keyboard gone). All other pins (PA0-6, PB0-7) are high, which they should be according to the datasheet of the CIA-chip 6526. The only thing that's connected to...

Hi all Life Happened(tm) so I went AWOL for 4 months. Sorry about that. There are a few kits left, about 20 (out of 250) I think. They can be delivered as plain kits or assembled. Just drop me a PM.

Hi Yes, it's available. I have however not had the time to login here for a very long time so communications is a bit late. I'm sorry for that.

Hello all Sorry for the long absence, I had to endure a very rough vacation with my family. But now I'm back again, and I will go through my inbox.

I have now updated the information, since the new batch (V1.1, green PCB) differs slightly from the old batch (V1.0, blue PCB). The difference lies in that the two resistor arrays were replaced with 8 resistors, for easier soldering. Also, board space / connector holes to support an OLED...

Hello all I have now re-stocked, and have over 200 units in stock.

Hi. There are now only 2 units left.

Pi1541 is a floppy-emulator for Commodore 64 designed and developed by Steve White, to be run using a Raspberry Pi version 3. Steve released the project as Open Source, and with the help of his drawings, i made some PCB:s and gathered the components required for a kit to make a "Pi-HAT"...

Finally I managed to check the stock. There are 4 units left. @eteP showed interest for 2 units, so if @omegamsx is still interested there are 2 left. Then I'm out of stock for this batch.

PM sent. @eteP and @omegamsx: I will get back to both of you as soon as I've checked the stock.

I've been playing this "new" (2012) game / remake on my PS3 the past week, and my verdict is: What a load of smelling bollocks! Comparing to the original X-Coms on Amiga (UFO Enemy Unknown), this so called game is ridiculously linear with ZERO variation. The so called tactical combat is nothing...

Connect this device to one of the joystick ports on your Commodore Amiga, Atari or C64, and a joystick + mouse (or joystick/joystick, or mouse/mouse) at the connector. Then, keep the fire button - of the inactive device - pressed for 2 seconds to make it active. Simple as that, no more hassling...
