It occurs to me when I make this change software that uses the top 8 bits of the A? registers for flags will start to fail. I am assuming that case is actually quite rare in QDOS? I have a quick look at the C source code, but could see were to change the ram size, but judging the previous comments,...

Hi, I can only allocate maximum of 16Mb in sQLux and UQLX, how do I increase the memory size? You need to change the code where allocation occurs. It occurs to me when I make this change software that uses the top 8 bits of the A? registers for flags will start to fail. I am assuming that case is a...

Whats a Q80?

Shorthand for Q60 @ 80 MHz

No.... A Q60 has a 68060 CPU, the correct shorthand would be: Q60-clock_speed, e.g Q60-66 or in your case a Q60-80 with a 80Mhz clock speed.

you have just implied a 68080 CPU

Sorry to disappoint, but its unlikely to suffice. For starters, as you know, I had a Q60 @ 80MHz back in the day, the fastest QL hardware available then (and now?) It still didnt feel "comfortable" I remember you saying that, but the 68060 @ 80MHz is 3-5 times faster than the Q68. So I th...

Sorry for the delay, in the end I had to order a new QL scart cable. Couldn't find my gbs8220 anywhere :( Well two cards work as shown, and the poor little kempston seemed dead. Probably the RGH2HDMI is a better option or Tom Daly's solution with another VGA upscaler, on a message thread on here. h...

I dont know how I can make it any clearer. Lets just say: The Pi4 with SMSQmulator is just within the border of feeling comfortable; the Q68 and Q80, for whatever reason, never achieved that for me. As you saw from my simple timing test, the Pi4 setup is >5x faster than Q68, so perhaps I was just t...

That was certainly the motivation for making sQLux work on linux framebuffer. I just haven't made a cutdown distro to launch it yet! For the future though would need something that could run SMSq/e! Hmmm... how about emulating a Q68 for that purpose? In a first attempt, you could try enlarging RAM ...

I have alot of these magazines, what year are we talking about.

From hardware point of view there is no blocking point.

What's misleading here? Few people just happen to have a Lattice JTAG programmer laying around.

I have one... and can provide an updste service

Hi, Since you are using Minerva, why use multibasic. To launch from Superbasic interpreter, I use EX pipep:;"program_bas>" which sends the Superbasic program to a ready only pipe, which loads a Multibasic interpreter, only channel #0 open, so all channels 1-2 have to opened explicitly. Fil...
