Re: Ohio-Indiana-Kentucky USA Vic-20 stuff

If I could figure out a way, I would like them. But I am in Chicago. It's a bit of a drive. I'll update if I can figure out a way. Otherwise, I hope they go to a good home.

Re: New penultimate-plus-2-cartridge

I enjoyed it the first day I tested it. I just did not know it would be the only day. :( Really hoping someone can make it useful again.

Re: New penultimate-plus-2-cartridge

Mine died on the second use, and I think support might be ghosting me. Does anyone here feel they might be able to work on one? ..or buy mine as-is? The buttons light up, but I get a black screen now. I tried the "dead test" and tried it on several different VICs running on different Ray C...

Re: Need Vic20 Music/SFX

I did a simple "song" in my 5 line game, "Trails"... here.

In line 4. A is a sound channel and F is just an ever-ascending number in the game loop:

Code: Select all

4 F=F+1:POKEA,(FAND25)+215
It's a snake game in five lines of BASIC. This was enough music to suffice. :D

THank you for the support! Lulu is clearly the way to go, I just figured out the Amazon version has frustrating format issues.

BTW, I have had similar orientation issues with phone pics here.

XOR in BASIC

Two variations of XOR (in BAISC) have been suggested to me. First: (X AND NOT Y) OR (NOT X AND Y) Then a reviewer (Daivd via GoodReads) suggested this would be better: (X OR Y) - (X AND Y) I would like to have different perspectives. Is this a better solution and should it replace the first one?

Re: Thank You

Thank you for being a part of this, Jason. This community started on a pleasant vibe and used to be much larger than now. It went through a very rough period full of bickering and discontent, but warring parties on both sides eventually lost interest and wandered off to other forums I presume. Occas...

Re: Jeff's VIC 20 Book

Thank you all for your continued support and encouragement! I remind you this is a free-time hobby project and will be far from perfect. I welcome and appreciate all corrections for future updates. Doesn't help either that two years ago I already suggested that SYS be corrected in Jeff's VIC-20 book...

Finished versions for Amazon (center) and Lulu (right). Updated the front page to explain the differences.

The Lulu version (right) is the same as the Amazon but with a nice coil binding.
