The Fun Of Old Your First Computer and other Books.

Submitted by NovellNetware on June 11, 2019 - 9:15pm

One of things I did was collect a very small amount of vintage computer books. For example the on in the Title. Your First Computer. We are talking 1976-(say) 1985 books or so. The book I was looking at the other day had an apple II in it. I never paid attention. I always thought it was a 2 plus. It is one of the later Apple II since it has air vents in the side. But the book and the picture explained it was just an apple II.

PSU Recap Question on Values

Submitted by KLund1 on June 10, 2019 - 9:13pm

Hi all,

  I just received a recap kit from Console5.com. A very good site for such items! I ordered the kit for the model AIIe I have, AA11040-B.

I started to remove caps, and noticed the replacement caps values are different. I am not a EE person and do know too much about what the values mean. I have read you should replace caps with same or better.

The large caps on the high side show 100uf 250v. The replacement caps is about 1/2 the size and shows 47uf 250V. Can I use these?

Just want to verify.

Thanks

Apple II Europlus - is all I need a startup disk?

Submitted by pete_r on June 8, 2019 - 4:05pm
Hello all - this should be a very easy question to answer for any Apple II owners. I have an Apple II Europlus with two disk drives - all clean and working OK however when I power the computer up all I get is Apple ][ on the screen and drive zero searches for a disk (which I don't have). As I've not used an Apple II since around 1980, I'm guessing it's searching for a startup disk. Is that correct, or should an Apple II be able to start up and display a prompt without a disk in the drive?

HELP! with new PEEK/POKE location post compile

Submitted by jlafleur on June 5, 2019 - 3:04pm

I have an Applesoft program that PEEKs/POKEs at 125 and 126 for the "next DATA line".

When I compile the software, it seems that the location of that counter changes and the program continues to PEEK/POKE at the 125/126 location, only the results are useless because it now stores that counter in another location.

I am using the Einstein compiler which seems to be the only one working for me/most ideal for my situation)

Need help with PEEKing the text screen

Submitted by gmontag451 on June 5, 2019 - 10:00am

I'm trying to convert a BASIC program which PEEKs the text screen, and I'm having a really hard time figuring out a similar formula for the Apple II. The original computer stores screen memory sequentially from top left to bottom right. But the Apple skips seven lines after every 40 characters (that's not entirely accurate, but you probably know what I'm describing.)

 

Beagle Bros has a short routine to solve this by positioning the cursor using HTAB and VTAB, then PEEK to find the memory location:

PEEK (40) + PEEK (41) * 256 + PEEK (36)

I guess my entire post was not posted with pictures. So I'll attach the pictures and leave the story telling for another day.

Apple IIe - LCD screen displays only B&W

Submitted by gmontag451 on May 30, 2019 - 11:45pm

My Apple IIe works in color with my HD TV,  but I can't tie up the family room with projects, so I dug out an old Philips PD9012 NTSC/PAL car DVD player which has a second detachable screen. The second screen displays color when connected to the DVD player.But when connected to the Apple IIe, this second screen only displays black & white, as well as incorrect aspect ratio. Is there a way to get color out of this particular device? (I'd be interested in correcting the aspect ratio, but I'm less concerned with that.)Thanks for any advice!
