Which "option for recovery" would you expect on an OS without memory protection, after a piece of software crashed?

No. The Q68 doesn't even heat up at all.

Re: Q68 Serial devices

BTW, for $18 currently on eBay they are selling USB to PS/2 converters. These things usually run closer to $100 Thanks for spotting this :!: Indeed it looks like an active converter, which is needed if someone wants to use USB-only devices with the Q68! (Some wired keyboards/mice are actually USB+P...

Re: Q68 Serial devices

A further question, why did you not design the Q68 with 2 RS232 ports as had the original QL, Qx0 and Aurora? It was a space/resource compromise. I wanted a decent metal case, where I can design the panels, and I didn't want it larger. Also, freeing the required FPGA pins for one more SER would hav...

Re: PCI Express video

I thought I had covered this with the explanation that what was being considered was a circuit / module that could be applied to a recreation or as an add on card to existing bbql - so FPGA with the CPU on board doesn't really fit the requirement if it's just a video add on for existing hardware. T...

How about a reply on this?

Re: PCI Express video

I have been thinking about this for some time too, and trying to figure out a way of getting QL video out of an HDMI socket. There are several hurdles and problems, but some thoughts below: 1) QL screen memory use is a little strange in the layout - so that tends to rule out all but a large CPLD or...

Re: Q68 Serial devices

On the Rpi I am developing a python script to catch printer output from the Q60/Q68 serial ports and send to CUPs for wireless printing. In this application, I don't see a strong need for a second serial port on the Q68. It is easier to set up an I²C slave on the Raspberry and adapt my Q68 I²C mast...

Let alone the fact that Ruptor apparently wants a bare-metal Raspberry behaving like a QL, not a Linux machine. From which even UQLX is miles away.

Cool setup! Did you already print your case?

Re: Q68 Serial devices

Question - is it possible to a easily add an additional RS232 serial port to a Q68? If you just need an individual solution and we can agree on some other pins you don't need, I could look into this and ask Wolfgang if he's willing to make a little SMSQ/E change for it. Such a tinkered solution wou...
