Re: SSSshhhhhh! T o p S e c r e t Project

Van,

I like the design, film tracks at the top, with a text run beneath.
What made you decide to place the adventure plot to the South Germany?

Any sequels planned after?

Re: MDV Low Level Routines

Dears, All, Just another thought, I was suprised to see that blocks belonging to the same file, are not writen one right after the other, but rather there seem 12 blocks in between. So perhaps catching every dozen's sector and its block, may work even in standard 128K QL RAM, as we get more time for...

Re: MDV Low Level Routines

Martin, Jan, Tobias, .., All Pleanty of feedback I have got, to delve into studying more. Gap 1 (that's the one between the sector header, you've just read, and the start of the block header that you want to overwrite) is 3600us. That's three and a half thousands of a second. Just curious, how many ...

Jan,

A little personal note, I use QED editor, is it your work?
People fond of MetaComco ED may forgive, I prefer QED :/)

Re: MDV Low Level Routines

Hi Jan, and All, Let me thank you All for all much useful clues and hints. I was somehow able to write sectors from the very start, but I was failing to see the results, as I realised I needed to remove just written OLD cart, put a NEW one in, do DIR on it - to trigger MEDIA CHANGE, put the OLD back...

Re: MDV Low Level Routines

Hi, With more confidence now, I am trying to update an existing Block on MDV as the next exercise. I believe I need to first position the tape on a given sector. I therefore scan all the sectors in a loop using MD.SECTR, until the sector I need comes by. I am surprised to see, that after each valid ...

Re: bv.chrix

Hi Dilwyn, Not sure I have the right answer, I looked in the Technical guide pg.50. A string is stored as a word character count, followed by the characters of the string. The string storage always takes a multiple of two bytes. I realised strings may have to be aligned on even boundary as I once te...

Re: QL's external MDV port

If you can make a suitable connector, QL microdrives should work, as the external port is just an extension of the internal microdive "bus". Hi, this is what I have to make a connector, original ZX connection piece, and an IC socket, to plug the QL MDV into. What is needed is a small piec...

Re: THE DISTRIBUTION - Word is out!

Dear Urs,

Thank you for putting this release out.

I was paying regular visits to you pages, I remember there used to be an interview with Linus at Zoo?
Also there used to be a source to Linus QL famous frame buffer code, I am not able to locate it anymore.

Can you please advise?
Many thanks
Tomas
