[Ql-Users] New document on DV3 drivers

[Wolf via Ql-Users]

Hi all,

I've added a small technical explanation of DV3 drivers for SMSQE to the 
additional info and data section on the SMSQE site.


Have fun

[Ql-Users] Buggy Christmas

[pjwitte via Ql-Users]

Re: [Ql-Users] Merry Christmas with SMSQ/E

Probably spotted by Dilwyn years ago, only weve forgotten.. ;)

It was a bad day for me for sure, as shortly after, thinking lightning 
wouldnt strike twice (and thus not being in a hurry to save..), I 
managed to bomb out again by feeding DISA 3.05 with a simple, chained 
sprite. One sprite was a mode 8 chained to a mode 4, and later, I 
tested a dynamic sprite: Two mode 4 sprites in a loop: Load into DISA, 
press defp and DO on the first line and.. well, you almost guessed it; 
it was more of a Ka-pfiffle, followed by wailing sirens..

yes, that part of SMSQ/e probably hasn't been touched for ages.

Hi,
yes that's a bug.
Somehow the return stack gets confused/overwitten (stack 
overflow!), causing a jump to a strange address where you then 
will get an illegal instruction error.
I've checcked that, under SMSQmulator this isn't due to the 
replacemnt FP routines, which it isn't.



It looks like it's an old bug.
On my SGC/AUR (SMSQ/E v3.26) the Kaboom is modest.
No error is reported, it just freezes after one howl from Sysmon.
No keyboard or mouse response anymore.

In any case, if you jump to an odd location (whether strange or not even)
on a QL you will usually be in big trouble...

To my mind, a "jump to a strange address" is not an address error which
would give rise to that exception.



He he that's a language thing :). 'Odd' in English can mean 'strange' but
also 'not even'. What I meant was the latter of the two so it really should
have been an address error...

I've checcked that, under SMSQmulator this isn't due to the replacemnt FP
routines, which it isn't.

On the Q68 it also freezes, but other jobs keep running (probably with

corrupted OS).
It looks like the processor in the Q68 behaves somewhat differently, as I'm
unable to get an address error exception even when jumping to an odd
address...
