Re: QL-SD ROM

Sensational! You've just opened new doors... If I remember correctly, the 768K Trumpcard (and clones) compromises the use of ROM port, or am I wrong? IIRC the Trump card only monitors a (first) access to the ROM port by the CPU to page in its extension ROM at $C0000 (note: not $C000) so the QL find...

Re: Can we learn from Amiga OS?

that's more or less what SpeedScreen does - It checks whether character positions align with font origins and handles this special case much faster than original QDOS. Well, in the end, QDOS doesn't literally call the PLOT routine, of course. Not only the character positions, also the various colou...

Re: MDV Software Reclamation

The rounding of numbers to 7 digits that occurs when SAVing is because S*Basic programs are saved as ASCII files, so the internal representation of floating point numbers gets lost. This is indeed a 'feature' of S*Basic I regularly ran across when I wrote programs for astronomical calculations which...

Re: Announcing availability of a QLNET driver for the Q68 (ND-Q68)

Finally, my Q68 already has QL NET installed by Derek Stewart. Derek has performed a very professional installation, the connectors are firmly installed and very discreetly on the Q68 right side. Looks very good. I have recently fitted it myself but chose to sacrifice the power switch for it. Fitti...

Re: Extra ports...

Many many years later I had an accident with a desktop keyboard and a cup of sweet coffee! So I did what you do, I took the keyboard apart (I think it was a Dell) and lo, inside was a little rubber/plastic bubble mat and a membrane! Sinclair was ahead of his time! I think most PC keyboards use memb...

And not just the version that's been laying around for years in scattered files on Dilwyn's site, but a complete ready-to-run WIN container that works over TCP/IP on QPC2, SMSQmulator and UQLX! It also contains the complete QL fil...
