Re: Q68 New users and general usage thread

qxltools is an important cross-platform tool for QLWA images, its comprehensive commandline functionality is nowhere provided by QPC. It deserves maintainance for 64 bit Linux and Windows, not bashing! Why? Using the PC as a tool for QL development, especially for large projects, commandline automa...

Re: Raspberry Pi emulator state of play...

This is why I was so happy to discover the Pi CM3 (Compute Module 3) a few months ago... It is a Raspberry Pi on a DDR SIMM. It's *tiny*. It just has the CPU, RAM, eMMC, and optional WiFi/BT on the SIMM. You provide a SIMM socket and the connections you want, where you want them. Best of all, ALL t...

Re: Q68 New users and general usage thread

qxltools doesn't seem to work on my system - These tools used to work in the XP / 2000, but don't seem to like Windows 7 or above. Perhaps it's time to run a virtual box and a legacy windows platform just to be able to use some of these. It works on Windows 7, just open commandline as administrator...

By the way, does someone have a comprehensive mirror of this important QL website?

Re: Q68 New users and general usage thread

I have also found a PS2 mouse that will stop the Q68 boot after displaying the PC.CLOCK. Thank you for reporting. Curiously an old and cheap optical USB mouse works perfectly with a USB to PS2 adapter. I have not yet come across a USB+PS/2 combo device that would not work. No need to look for "...

Re: Q40 and Q60 video controller for flatscreen monitors

Pictures from Mr. Mark Smith in this FB thread where he describe his attempt to replace an old CPLD on a TC2068. I hope it can help... ;) Thanks, but not so much. Your pictures showed a PLCC IC replacement soldered to SMD pads on PCB. I have done that before, but it is not suitable for the Q60, whi...

Re: Q68 New users and general usage thread

UK: 240V 5V EU: 240V 5V USA: 110V 5V Rest of World: No idea of the mains electricity in every country. Too many options. Yes I know Derek. There have not yet been damages by wrong supply, no major problem. Maybe it would be an option to offer a USB to 2.1 mm cable, so people can use USB style suppl...

Re: Q68 New users and general usage thread

I follow the reasoning that Peter over estimated our abilities in this area. ;) No, I simply assumed the Q68 would ship with power supply. Is there any protection on the 5V input against over voltage or reverse voltage? Not onboard. There is a header with 5V input, 5V output and ground, where addit...

Re: Q40 and Q60 video controller for flatscreen monitors

So what would you do, just let the outline cut through the pads and specify nothing?

Re: Q68 New users and general usage thread

Is this power supply acceptable? Unfortunately it is not. One has to be careful with multi voltage wall power supplies, most are unstabilized. General rule: If the description does not explicitely say that it is stabilized, you can assume is not. The ususal USB-PS/2 adaptors will only work for comb...
