QLion Gold Card

[Peter]

I thought SMSQ/E could be loaded at RAM address 030000 (after the "dual screens" effectively), but I am not sure if it makes any assumptions about memory layout lower down in the memory map.

It does make such assumptions, but even if the hardware was enhanced accordingly, a QL version of SMSQ/E would be needed. Which never existed.
As Leon wrote, he'd probably have to emulate a Miracle Gold Card.

Well, actually it needs write access to the lower memory to install its trap and interrupt vectors. CPUs starting with the 68010 have a VBR register that would theoretically allow to put these vectors elsewhere, but SMSQ/E doesn't make use of that, afaik.

It's actually up to the concrete platform implementation where it wants to load the actual SMSQ/E code - Most implementations, however, seem to put the OS modules as far up in the memory map as possible, because SMSQ/E assumes contiguous RAM starting from address 0.

Hi, well I could have a dual fpga configuration option and one of the configurations customized for SMSQ.

To place the SMSQ/E binary at $30000 initially is sort of default, unless there are platform specific requirements.

[...] because SMSQ/E assumes contiguous RAM starting from address 0.

But only a little 4 KB chunk. At various areas above that, it can be registers or screen, until the main RAM starts.
Also it doesn't strictly have to be RAM. E.g. for Q40/Q60 it is a ROM emulation area which is read-only after the initialization.

Hi,

I tried SMSQE_GOLD v3.41 on the QLion Card that I have, which as expected crashed the machine. So to get SMSQ/E running, a new version of SMSQ/E suitable for the QLion hardware will be required.

I am quit happy with Minerva, which allows builtin multitasking Superbasic.

Am enhancement would be 16 Colours in Mode 4, which at present Mode 8 is being used.

I did a little increase in speed.

and a bit more

and now

Good grief, my friend!
