ImageWriter II alignment issue?

Submitted by Alps Aficionado on November 15, 2023 - 1:41am

Received what seemed to be a working ImageWriter II. Printed a whole (small) banner with a black ribbon. Tried again with a color ribbon a few weeks later, and found that the printer could not reliably keep its printing area aligned from line to line. No matter what I try, I get a "wobble" in the margin on the left and right, and eventually the print head is horizontally misaligned enough for it to stop printing and start blinking the error lights. 

I've tried adjusting the color ribbon adjust ring, but I'm not entirely sure what I'm doing.

This is similar to the Vince Briel version of the card, but supposedly with some additional capabilities.

Stunt Car Racer ported to Apple II

Submitted by cobbpg on November 6, 2023 - 3:06pm

Hi folks,

I created a port of the C64 version of Stunt Car Racer to the Apple II. Here's a video demonstration with a download link in the description: https://www.youtube.com/watch?v=N2uZCSfIqR4

All it needs is 48K RAM to run. Since I have no access to real hardware, I could only test the game with AppleWin, and I'd love to know if it actually works as intended on the real deal.

Apple II+ hard reset

Submitted by tony359 on November 4, 2023 - 4:00pm

Hi all,

I'm trying to find out if there is a way to perform a hard reset on an Apple II+ without having to power cycle the machine.

The background is: the machine is on display in a local no-profit computing museum and it would be great if there was an easier way to start another program than reaching at the back for the power switch.

Is there a way to wire something onto the motherboard so when triggered it performs a full reset as if the computer was power cycled? Thank you!

Apple Schematics

Submitted by Stargeezer on November 3, 2023 - 11:25pm

Kind of a wonky question here.

A while back, I found some very nice pdfs of Apple 1 schematics.  I had them printed on cardstock and I have them as art on the wall.

I thought about doing this for the II+ and IIe.  Finding schematics on Asimov or RetroActive is not the problem, what is a problem are the number of pages that make up the schematic.

Has anyone ever stitched together some of the pages to make a more contiguous schematic?

Doers anyone know how to stitch pdf pages together?

Red light on duodisk drive and constantly running

Submitted by JorgeL on October 31, 2023 - 1:19pm

I recently changed the rifa cap on my old Apple IIe and after putting everything back together my duodisk drive is constantly spinning and has a red light on at all times.  

I am pretty new to this, so I am not sure what the issue could be. Before changing the rifa everything worked fine.

Apple II (Not Plus) Board has Issues

Submitted by DistantStar001 on October 29, 2023 - 4:22pm

Recently got a Rev.2 Apple II board.  Originally had AppleSoft ROMs, But the AutoStart had a bad pin (broke off) so I replaced them with an Integer set I had on a II+ board.  The board boots to the Machine Monitor, and with a ROM switch card (AppleSoft onboard) in Slot 0, it will go to BASIC.  I connected a Disk II in Slot 6, and put in a copy of Apple-cillin II.  It loaded fine, so I tried a copy of DOS 3.3, and it either hangs after splash screen or crashes.
