System Saver: Is it needed?

Submitted by machan1985 on May 8, 2019 - 9:45pm

My enhanced Apple //e came with a System Saver cooling fan / surge protector... but I’m wondering if it’s necessary. The ][ was designed to keep cool, and I only have a Disk ][ card and SSC installed in the slots. Is it safe to remove the fan, or do I risk over-heating?

Apple II+ won't boot...displays numbers instead

Submitted by Statsman1 on May 7, 2019 - 3:11pm

Hey guys...

Once again, I seek your wisdom.

I have reseated every chip, and replaced a whole bunch of corroded / blackened chips in a II+, and I'm still basically where I started. 

Power ON

<BEEP>

APPLE II shows up on the top of the screen

DRIVE 0 (in slot 6) starts booting as it does, that reset sound it makes, and then it sounds like it's loading, and just when it starts to load...

...a string of numbers from 5 through 9 prints in a column on the screen (with an occasional 8F in there)...

...and then it stops.

Help with reassembling an Apple IIe

Submitted by gmontag451 on May 7, 2019 - 12:53am

I inherited a disassembled Apple IIe. After a few repairs, I'm almost done reassembling it, save for two problems: 1) The long springy metal strip that makes a connection with the removable lid is not attached to the case. (I believe it's a grounding strip.) I see the scratches in the lid, but I simply can't work out where the strip goes.

Apple Handcontroller //e Issues

Submitted by machan1985 on May 6, 2019 - 6:05pm

Hello, all. I recently received a pair of Apple //e Handcontrollers ( as shown) but it appears there is something wrong with the analog locations. While running Breakout, the paddle twitches and jumps all around. I wrote a small program that outputs the value of pdl(0), and saw that the value will sometimes spike while turning the knob, seemingly at random, but will never be above 244. Additionally, there is a large "dead zone" when the knob is turned all the way to the left... the value stays at 0 while turning the knob to the right a little. What could be causing the issue?

A][e Ram & Keyboard issues

Submitted by KLund1 on May 5, 2019 - 4:58pm

Hello

I have what I believe is standard IIe with just an 80 column, and FD cards

On power up I get the standard Apple II screen. Pressing Ctrl-Reset I get the space bar key repeating. If I press another key then that key repeats.

If I dosconnect the keyboard, and power up I get RAM: in the upper left corrner, and the self test never finishes.

Suggestions of fixes?

Thanks

CPM on 800k Floppies or HDDs?

Submitted by hlenz on May 2, 2019 - 7:57am

Hi,

 

I'm running an Apple //e with a MS Softcard and an SD-Disk][ floppy/hdd emulator.

Works perfectly for DOS + ProDOS, can also boot CP/M 2.2 and CP/AM 5.1 floppy images off of asimov.

 

I'd really like to get my hands on an 800k floppy image (.2MG) or a small hdd (.hdv) image with a bootable CP/M OS on it.

Has anybody had any luck finding this? 

I suppose that just using ciderpress to convert the .dsk will fail, since CP/M hardcodes some device tables...

I appreciate any pointers or discussions!

Cheers

We made a GUI for our microM8 Apple II Emulator

Submitted by paleotronic on April 25, 2019 - 5:25am
Hi everyone! Recently we’ve had requests from users for both an API (an interface for controlling our microM8 Apple II emulator externally) and a GUI (a graphical user-interface native to the host operating system). The lack of a native GUI has always been an issue for users: microM8 is designed using a cross-platform OpenGL framework called GLFW, but GLFW offers little in the way of UI controls. Also, an API would allow people to automate emulation functions, for example to test .WOZ-format disks created with Applesauce.
