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

Re: RasPiQL

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...

Re: Disk interface

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...

Re: RasPiQL

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...

Re: RasPiQL

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 ...

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.

Re: QDOS PE FileInfo II

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...

Re: Want: QL-SD drive

Hi I asked if I could build the QLSD v2, but was politely refused. Quite a revisionist statement. I wrote, literally "well, if you want we can talk about that, sure. But the problem with the current QL-SD is that there is much manual labor involved." and then a long text of what must be d...

Re: RasPiQL

Exile, XorA, Derek, .. I presume you put the whole system on the SSD and boot off that? Could you give a quick step-by-step overview of how you do that? One day soon, M$ are going to stop supporting W10; my desktop machine is not W11-compatible. This might be a good time for a serious paradigm shif...
