A new thread on an old subject.. Overscan.
Without naming names.. Darklord
(oops I've done it... lol) want's to fix/centre the display output on his idea of putting a newer LCD/TV in his STacy.
Problem is, We are not the first to notice that often the display is badly centered on the screen. The allowable 'menu' adjustments are not as forgiving as they could be.
Overscan won't entirely fix this hassle, but it does give an opportunity in perhaps taking advantage of those spare border pixels for some applications that CAN use the additional area.
Often those programs that run in mono anyway for the obvious benefits of increased resolution.. are happy to have more... like Calamus, Page Stream, Cubase, LDW Power.....etc
So, Ron and I are planning to work out if the mod will work in his STacy. I'll have to make at least one more for him (And I thought I had one spare... hmmm.. can't find it...bugger)
If it happens that this is also compatible with SainTs HDMI output mod.. then that is just even more perfect.
I plan to do another batch.. maybe professionally, or just a few by hand as usual... it will be three or six PCBs..or one, depending on interest and etching results.
Software compatibility is actually rather limited really.. no games, and only some agreeable 'serious' software can use it.
But it works, and better than the original 'AutoSwitch Overscan' hardware IMHO, not additionally limited to >TOS 1.4....like the original... This version is pretty good I think.
LASCAN. I've used it quite a bit.. and am generally pleased with how it runs...Using CAB browser, and Devpac3 is perfect for me.
My question is. Is there an interest in a proper professionally produced LASCAN mod. Its looking like anymore than 10 interested persons is worth the effort.
Otherwise I'll hand build just a few again like last time, and wait for a customer for another couple years.
The mod isn't my design, nor is the software. I am only making the PCB, and whacking on the ICs that make it work according to the original instructions.
All risk to you if you want to try it. I know it works- and there are other members here who have one of my boards and got the same or similar results.
I could post screen shots and stuff, or link to my original thread when I did it myself. For now it is just a question. How many to build?
It only works on pre-STE machines. Megas'/STs, and hopefully the STacy.
, and the wiring requires CUTTING of some motherboard tracks. Much fun.
PS, The software for LAscan that provided its source code proved immensely useful when I was playing with the 16Mhz overclock mod. After some minor changes it was able to control the overclock mode with software using the alternate ACIA chip in the Atari.... Now that was awesome!
