Re: uQLx 2018a

Hi, Having used tge forked version of UQLX 2018a, which looks a little faster and it seems to run all the software I have. I added in TK2 223 which gives Level 2 device drivers, hard directories. I would like the ability to have the second screen enabled, maybe from a command line option. As far as...

Thats what the manual says, but its not actually true ;-)

If you didn't find it you are looking at this bit of code.

Re: uQLx 2018a

uQlx searches for a fixed sequence of bytes to detect PE from memory.

Its possible they older one does not have this sequence (or its just a bug).

Can you point me at exact download and Ill try and look at it, but Im off to Orkney at end of week so may take me a couple of weeks!

That version of the VM turned out to be significantly slower and unstable on modern glibc so I disabled it!

Re: uQLx 2018a

Are you running uQlx as a 64bit compile? (there are some other issues noted elsewhere in forum in 64bit) Did you compile the correct branch? (https://github.com/SinclairQL/uqlx-fork/tree/XorA/working-tree-64bit - this includes "fixes" even for 32bit) Its been a while since I tested with PE.

Re: Raspberry PI 3B+

There’s also ZEsarUX which is available as a pre-built binary for the raspberry pi https://github.com/chernandezba/zesarux/releases - this package emulates a number of Sinclair computers, including the QL - I’ve mainly used it as a ZX81 emulator on the pi, so I’m not sure how the QL emulator compar...

Re: Chromebook

Just been asked something I've never really thought about...anyone know if any of the QL emulators can be run on a Chromebook? Probably not since they mainly run online apps I suppose. e.g. if Java is available for them and SMSQmulator could be run? Yes MAME can run on chromebook, it can be compile...

Re: Zip to MDV

Yeah it was never in the C spec that you could guarantee the placement or alignment of structure members, people just learned to rely on behaviour from certain compilers. Modern compilers move the values to generate less instructions on modern wide bussed CPU's True, but I've never come across any ...
