The Sinclair QL Forum

I didn't talk about the 64K color mode of QPC2 (SMSQ/E) but high resolution with (at least) 4 Colours. This is perfectly working on uQLx, sQLux and as far as I have read, Jan Breedenbeck implemented it also for Q68. So it shouldn't be a great task to implement it in Qemulator.


That would ...

The Pico boots minimal code in almost 200 msec after power-on, which is less than the reset times I have seen on my QLs.
How reliable that would be, is a different question.


Good to know as I have not measured the QL reset time, yet.
From some experiments with the Pico dev board and other ...

Can Q-emulator (as UQLX/sQLux) be used with a large screen (at least 1024x768 4 colours) with Minerva or does this only work with SMSQ/E?


Q-emuLator emulates hardware like the CPU and video output. It also offers some file device drivers for file systems that were not available originally on ...

I only tested Minerva+Aurora once, some years ago, after I bought QEmulator. As far as I remember I had to use Poke 98371,144 to enter in Aurora 1024x768 256 colors mode.
I tried now again and it seems to change mode, but the monitor shuts down :(

Hi Andrew,

Aurora and Q60 emulation ...

Ooo! Intriguing project, Daniele!

Any comments to add???


Just playing around, I really like the price point of the Pico, especially now that it has wifi. I'm also interested in trying the PIO programming at some point, but it's not needed for the first project.
The board itself is just an ...

Just a little hint:
If you have no power supply plane, you should try to make the VCC traces wider.


I appreciate the advice, thank you! I'll change it in the next version, it's currently 0.4 mm.
Better I don't show you the other side then :D as there is not even a ground plane. I plan to ...

Arrived just in time for the weekend, planning to experiment with electronics...
Also got two of them with the SMDs already assembled.

It could be the ZX8302

About this part, integers are faster to use in compiled programs and probably SBasic, but are slower in the original SuperBASIC, since QDOS converts them to/from floating point when they are used.

Can you actually get more than one microdrive running at the same time?


As Martyn says, it's not possible.
At most, you could have some motors temporarily spinning at the same time due to physical inertia and capacitors in the circuit.
I think multiple leds can be on at the same time when ...
