Re: How do I redefine characters with 8k or more RAM?
I didn't understand that there was math involved in creating that number. When you did not ask about that detail, it was foreseeable to me that you would run into this issue: next logical step after redefining part of a character set would be redefining the entire character set. I did not want to l...

Re: Assembler
As you had some exposure to the Acorn Archimedes series, and if you're adventurous, you might consider using the inline assembler of BBC BASIC, the one contained in HI BASIC (part of the !65tube emulation) in particular. :mrgreen: Otherwise, quite some people here use either dasm or ACME , so there ...

Re: What do I need for a NTSC to PAL conversion on a short board?
You might want to take a look at this thread: VIC20 NTSC > PAL Conversion.
The OP links to a document on zimmers.net: PAL VIC20 Goes NTSC (just backwards).

Re: ELITE
Hi, Meryt, [...] it's really ground my gears all my life that there's no version [of Elite] for the VIC. I understand why. The bitmapping makes it next to impossible.

Re: VIC20 with NOS 6561 sound problem
Even though bigger memory expansions shift things around on the VIC-20 (notably, BASIC memory and text/colour RAM), the behaviour and position of I/O (VIC and VIA) remains unchanged. a 35K RAM expansion (which I think pages in the cart memory over the built-in SRAM unless anyone can say different) T...

Re: Jeff's VIC 20 Book
This is a tip: To plot the cursor on position x,y on the screen: X position is on allocation 211 decimal and Y on 214. But it doesn't work because what is needed is a print HOME and a PRINT after POKE 214,Y-1. It took me hours to find out. I found the answer in Compute!'s Gazette of december 1983. ...

Re: Can the display window be re-triggered? (was: 9001 when read?)
what if I do racing the beam and set $9001 later so it compares more often to $9004? As I wrote: you can't restart [the display window] after it ended by writing a corresponding higher value into $9001 ...
