The Sinclair QL Forum

If it comes that far, most of CPU, ROM and RAM must be functioning.

About at this point QDOS changes from linearly executing initialization code to becoming an interrupt-driven system. I'd check if the interrupt lines /IPL0-2 and /IPL1 on the CPU for pulses. The ZX8302 should generate a 50Hz signal ...

Hi Dave,

I have a Minerva mk2 on my goldcard QL and have been using the I2C on a couple of projects. So if you have any question, let me know.

Hi François

I’m trying to determine if the I2c interface on the Minerva mk2 remake is working and I wondered if you’d be willing to share ...

SuperBASIC has specific boolean operators

&& for AND
|| for OR
^^for XOR

The logical operators do not operate bit-wise, but consider everything that evaluates to "0" as FALSE, and everything else as TRUE.

The mobile outages seem to have been fixed (according to an email reply I got from the local Plaid Cymru politician). Exactly the same issue as I've been moaning about the power outages - the short power blips locally nobbled the power supply to the mobile phone transmitter. After I got the ...

TxD and RxD are in fact on different pins on ser1_ and ser2_, just like CTS and DTR.

And some of the confusion has a lot to do with the fact that Sinclair (sometimes?) had the weird habit of labelling pins with "what needs to go in here" rather than "what comes out here"-like everyone else does ...

In the 16 color mode (which was unfortunately never used)... If TT had written such a driver, we would also have 16 colours on the Atari TT without QVME, as the TT is able to show them in 640x480.

Hi Ralf,

I know Tony Tebby wrote an Atari High Resolution mono screen driver, for Atari ST, but ...

What does mean IPC? I know in some context what it means, but here no idea.

Recently I learnt that BBQL doesn't mean barbeque. So... that is my level

The 8049 keyboard co-processor. (Sinclair's naming was "Integrated peripheral co-processor", I think).

Seems to play nicely with sqlux, although I can't hear any sound there.
QPC is a bit hesitant to run it.
And the BBQL of course likes it ;)


have you set a sound level in the ini file on sqlux?
SOUND = 10
something like that. without it sqlux wont give sound.


Indeed, that makes it beep ...

Just for completeness (I understand the game is for the BBQL):

It seems to talk to the IPC directly instead of using MT.IPCOM calls (or, tries to talk to the IPC with interrupts off). Thus, the game will likely not run on anything that doesn't have (or fully emulates) an IPC.

It runs well on the ...
