APPLE II REDBOOK 1978

Submitted by Khaibitgfx on July 11, 2019 - 6:16pm

If anyone needs a new updated copy of the Apple II Redbook you can email me for the PDF, it has many improvements over the 2008 PDF which I also made.

This version contains many new pages that were not done in 2008.

In the months to come the entire Redbook is being redone with all pages complete.

Coming soon will be the Apple II Bluebook.

II+ in the clear

Submitted by dorkbert on July 10, 2019 - 10:34am

I wonder where the shell was sourced from; since AFAIK Apple did not start doing clear shells for proto till Image Writer II time frame.

Trying to find Avalon Hill Tournament Golf disk image

Submitted by old_hitech on July 7, 2019 - 2:30pm

I am on a golf game binge and have an original disk for the Apple II Avalon Hill Tournament Golf game. I bought this game back in 1980s and remember having fun playing it. But now the game disk will not boot and I cannot play this game. I've looked for a disk image at many Apple II disk repositories and cannot find this one. Anyone out there have a disk image of Avalon Hill Tournament Golf for the Apple II? Thanks!

New Owner of a Apple IIe

Submitted by mbc230 on July 4, 2019 - 12:25am

Hello All....Great forum and glad to be a new member. I am a proud of owner of a recently purchased Apple IIe that I bought off of ebay (Price was right). Well I unboxed the computer. It came with a color monitor (with a broken RCA male end stuck in it. Had to take monitor apart to remove it), CPU was full of rat poop (Seller claimed the computer was in a storage unit (Had to take apart to clean it all out), and came with the dual set top DuoDisk disk drives. So the issue I am seeing is no matter what disk I put into the drives the red light stays on and the video is displaying Apple IIe.

Apple IIe strange issue

Submitted by mamejay on July 3, 2019 - 9:58pm

Hi everyone,

Very new to owning an Apple computer.

I recently got my hands on a couple of Apple IIe computers.

One is working fine the other seemed to be dead. 

Both have boards Logic Board ID: PCB: 820-0188-A (International) - REV: 607-0288-C in them.

I managed to get the non-working one up again.  It had a short to ground on the 12v line which was caused by  a bad 10uf cap.  Replaced that and we have power LED.

Emulating a Disk II via rPi GPIO.

Submitted by Lee Adamson on July 3, 2019 - 12:15pm

So, since I have an rPi in my //e anyway, and since it has plenty of spare GPIO pins, I thought maybe I'd try hooking some of them to a Disk II controller and writing a unix daemon to emulate a floppy drive.  I'd think that the rPi would be fast enough to do it all in software, especially if it was running a realtime kernel......  But I dunno.....

Selling a NEW Apple IIgs: turn it on or not?

Submitted by mnemonic on July 3, 2019 - 2:18am

Hey everyone, I am facing the following dilemma: I have a new, unused Apple IIgs that to my knowledge was never powered on. It is a rev 0 model from 1986, so it is almost 33 years old. I would like to sell this machine and I wonder if I should turn it on for testing at all, which bears the risk of the power supply dying, leaving me with a dead unit. On the other hand, I could sell without testing it, in which case I cannot claim that it is working. Which would probably reduce its value. What are the odds that the power supply dies when I turn it on?

Copying floppys with Apple IIc

Submitted by Tavast on July 1, 2019 - 7:39am

Hi Apple folks,

 

I have Apple IIc with the original package and software disks that I run everyone now and then together with my other vintage computers. Well, I have one very early original Ultima game that I would like to back-up onto another floppy. What is the best way to go about in this, where can I easily find a program that could do this?

 

All help appreciated!

Weird Broken ProDOS

Submitted by TobyJennings on June 29, 2019 - 11:25pm

After I got my old //c working again I went through the box of floppies I had on hand. These were all from the 80s and with a few exceptions were all non-commerical disks that we'd copied from friends or as backups. I set about working backward and bootstrapping from a "known-good" state via ADTPro and set to capturing as many of these disks as I could as archival images.
