Try this: (you can break it anywhere) 10 print chr$(205.5+rnd(1)); :goto10 Or mod this C128 program - few commands - no problem: 100 dim j,a,b,x,wl,hl,a(3) 110 a(0)=2:a(1)=-80:a(2)=-2:a(3)=80 120 wl=160:hl=32:sc=1024:a=sc+81:ym=11:xm=19 130 graphic0:print"{CLEAR}" 140 fori=1to1+2*ym:print&...

Ok, thank you very much! My last Q is to banks... I'm not writing for C128 bankswitching. C64 allows to use also space normally under ROM $A000-$BFFF and $E000-$FFFF turn off and use it like RAM. Difference is to VIC20 that C64 has 6510 CPU. VIC20 uses 6502 CPU and I don't know if it allows anything...

Hi! I was searching commented ROM/RAM disassemply/map for: - value for A, X, Y register for SYS command - success - found - value SP for SYS command - success - found - SYS routine address - success found - LO and HI byte for use with SYS command as address - never found Like we know SYS command can...

I'm sorry for Z80 Videopak and really is for C64. But I collected info about Z80 and 80 column cards long time ago and there found my mistake. Here are collected info (I can add pictures and manuals to some of them: BI-80 uses MOS6545 incl. RAM Expansion and Basic 4.0 by Batteries Included C64 80 CO...

Hi! I'm still new. First I needed to know that 6502 in VIC20 is different to 6510 in C64 or 8502 in C128. I know difference. I want to ask if is possible to turn off/pause 6502 CPU by any expansion port signal in IO space. Is it possible? Why: I'm discovering two things: 1. SCPU64 and SCPU128 are co...

Thank you. Useful.

Ok, understand. So, no any direction register.

Of course I know that only common keys will work. But it needs to say that in C64 mode of C128 is possible easy to make them active and working. Ok, pinout I'll find - I needed to know if is it possible. KVM switch - I was using for C128 and C64 simple parallel port manual switch - nothing more. C12...

Hi! I'm C128 and C64 programmer and both machines have $0000 and $0001 as data direction registers. They're different in some parts but function is same. My Q is: C64 allows to control Kernal and Basic ROM overlay in RAM by $0001. What a function have these addresses in VIC20 and is possible anythin...

Hi! I want to buy VIC20 and I'm active on C128 computer and scene. I want to ask if is possible to connect C128 or C128D keyboard to VIC20 by internal keyboard connector. Sure is that I don't know what a connector has VIC20 internal keyboard. Some non-drastic changes I know to do. Why: I want to use...

Sure single file apps are less commonly and current core supports only PRG and CRT. This was reason for searching CRT of Minigrafik. But in world of 128 or 64 is possible to create CRT from simple ML program. Is it possible also on VIC20? C64 and C16 core supporting 1541 diskdrive (in my eyes worst ...

Hi! I'm here new. I'm really 128er and TED Series fan, M65 user. Few weeks ago I bought MiST FPGA and downloaded VIC20 core - I know, everybody of you can tell "That's not VIC20!" - yes, true, but before this I knew about VIC20 near nothing. Experiments uncovering me VIC20 features, never ...
