Torsten sent me that customized version a long time ago. This version however only works on real hardware when the +3K RAM are fitted internally, like in the VFLI mod - and that's specifically the reason I asked for it. The VFLI mod is emulated in VICE, you should consider though that if you go and program anything that requires the mod, the result will have a very small audience.MrSterlingBS wrote:do you have a s[ol]ution for this question from Mike?
Is it possible to move the screen to $0400?
VICE then behaves as if RAM was present in addresses $9800..$9BFF (I/O2) or $9C00..$9FFF (I/O3). Nothing special about that.And how can I physically imagine the extension I/O-2 RAM ($9800-$9BFF)?
How does the I/O-3 RAM ($9C00-$FBFF) expansion work?
I fetched that book from DLH/Bombjack and on page 45 nothing is mentioned about the locations of BASIC and KERNAL.Isn't that where the Basic and Kernal are located? See Mastering the VIC from A.J.Jones et alia on page 45.
That info in turn is referenced in Appendix M on page 173, which mostly gets the facts right, except for the following detail: BASIC is (mostly) located in $C000..$E4FF, the KERNAL resides in the following address range, $E500..$FFFF. That means, BASIC is more like 9 KB in size and the KERNAL is 7 KB, so part of the BASIC interpreter actually sits in the so-called KERNAL-ROM.
It can be disputed, whether the reverse ordering of the addresses on pages 173/174 is pedagogically valuable.
