Fully agreed. The GoldCard even takes the very core of a computer away from the QL motherboard, which is CPU and main RAM.

Ingenious idea! I wonder if it could be improved by solid panels at the sides, so top & bottom become fully planar.

This acronym is especially problematic when hungry. The first three letters always make me think of spareribs and steaks.

Re: Q68 pads for reset button

The bootloader ROM coming up at power-up is write protected, but not the OS that was loaded. Like you, I assumed for a long time that some programs might need a write protection, and the Q40/Q60 therefore had a hardware feature to write-protect RAM at $0. This assumption turned out a fairytale, nobo...

Re: Boot Q68 without monitor and keyboard

Thanks. Not sure if manually soldering BGA deserves congratulations or commiserations. It was absolutely painful. :?

Well spotted ;) The two SDRAMs are fully independent, allowing either dual CPU cores or video memory separate from main RAM.
The bottom side also holds a QL-SD style MicroMatch connector.

Re: Boot Q68 without monitor and keyboard

Your Qzero is a great idea. I counted 66 potential I/O pins. What does your current configuration support. How difficult would it be to create UARTS, PWMs ADCs, DACs etc. Support for RS485 would be great. I Know that no drivers exist for such I/O but I am sure they would be written if the hardware ...

Re: Boot Q68 without monitor and keyboard

Now my Q68 acts "unattended" as a server and gateway with QPC2 <-> BBQL . Everything is OK!! Good to hear that it works for you now. By the way, I designed a piece of hardware which seems ideal for this purpose. I did not plan to talk about it yet, as I may not spend the time for a public...

Just detach them and boot the Q68. No idea what problems people are seeing here.

The schematics from Dave are fine.
