Re: Problem at boot time

What happens when you swap the QLs between the two sets of expansions? Does the problem stay with the respective Gold Cards, or does it stay with the respective QLs? It would be difficult for me to test this because the SCG was modified to work with a backplane (I don't remember what modification I...

Re: Problem at boot time

For me this looks like a bad contact somewhere (memory ?). I had a similar problem, it went away when I moved the SGC DRAM chips a little inside their sockets. Hi, Thank you all for your answers. Based on your experiences, I carefully removed all RAM chips from the SuperGoldCard, I inspected them a...

Problem at boot time

Hi, I currently have 3 QL systems, 1 Q68, 1 SGC + Aurora and 1 original QL + GC. The Q68 works perfectly :-) However, the other two are giving me troubles but only when booting: The Gold Card System problem is the following: When I power up the computer, it boots as it should i.e. first memory test ...

Re: TF Services I2C drivers

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.

Re: QL 34th Anniversary new hardware.

Interesting device !

For the Q68, wouldn't communication through the I2C port be faster than using the serial port ?

Re: Q68 serial port

If you don't want to use QL-SD, an emulator, or wait for QLNET support on the Q68, the fastest way is probably to ZIP flopppy contents to ramdisk and then simply COPY it to SER1, even without XON/XOFF. If the QL is the sender , the lack of Q68 hardware handshake does not matter. The Q68 is fast eno...

Re: Q68 serial port

Hi, Can you not copy all your data into a QXL.WIN file and transfer the file to a SD Card via PC or QPC2. To answer that part: I don't have a PC, being a mac user. So for all those years QLers where playing with QPC, I was not. I was developing directly on the SGC QL. For many years the workflow to...

Re: Q68 serial port

Thank you Derek for the information. I know there is no +12V pin on the Q68 serial connector. But my question was about the signal themselves on the Rx and Tx lines. The RS-232 standard stipulate (from memory) that a bit value of zero is transmitted with a volage anywhere from -3 volts to -12 volts ...
