Re: Ubuntu 14.04.4 and uqlx2017

The uQLx versions I built years ago for the Raspberry Pi and the Efika actually had a working TCP/IP driver (although I never tested it beyond some basic packet transfer tests, and definitely not against your driver, which didn't exist at that time). That means: It should in principle be working, as...

Re: QL Tinkering

Bah. And I was typing up a long answer quoting the exact same sentence of the book. :D

Thanks Andrew!

Re: PSU alternative?

This is not so easy to answer - it depends a lot on the "stiffness" of your power supply under load. Power supplies are typically reted at a voltage that can be maintained under a typical load - Note, what you would measure on an unknown PSU is the open circuit voltage which is typically m...

That's simple. It's not implemented.

Re: Ubuntu 14.04.4 and uqlx2017

I'm not sure why you would want to use TV mode in uqlx - That doesn't make much sense to me, as the reason , the small screen and some characters lost on the left doesn't really apply here. The ROMs are not patched, to my knowledge, but rather an F1 key press is simulated after starting the emulator...

It does. You must have lost the headers before.

Re: QL-SD problem - help needed

That means your QL has very probably seen a motherboard change - The serial number seems to be for an issue6. Issue 5 QLs can be reconfigured by changing JU1 and to JU6. The circuit diagram here has a dotted box to the bottom right that gives the proper jumper setting. You need configuration (7), wh...

Re: QL-SD problem - help needed

Interesting. You seem to have an issue 6 QL that was retrofitted with EPROMs. (Issue 6 normally came with ROMs and lacked the circuitry issue 5 had that allowed to easily change between various ROM and EPROM configurations). An issue 6 QL should have a 23256 as IC33 and a 23128 as IC34. Yours seems ...
