ISO Gerber files for Ralle Palaveev's ProDOS 512K NVRAM drive

Submitted by skate323k137 on December 20, 2022 - 8:02pm

In search of gerber files for this project, before I take the time to make them from the provided schematics. I don't do Facebook so I don't know if anyone has shared around a kicad/gerber file or anything.

 

The project is: https://github.com/rallepalaveev/Prodos-512kB-NVRAM-Drive

 

This would be really useful for me, I'm not out to make a bunch of them but a couple for personal use would be super useful. I already have all the ICs on hand I would think, so a few unpopulated PCBs is really all I need.

Plugged CGA monitor into IIe joystick port

Submitted by attackracer on December 20, 2022 - 10:51am

Hello everyone,

 

I fear that I may have killed my apple IIe by plugging an IBM 5151 cga monitor into the game/joystick port. It no longer beeps, and the power led stays on. No video output. As to how this happened, I have an Apple IIe with a PC Transporter card from Applied Engineering. I plugged the monitor into the wrong port.

I've taken all of my expansion cards out, and measured resistance on all of the voltage rails to ground. The 12v rail had very low resistance (6.5 ohms), but raised to over 800 when I unpluged the keyboard.

Help wanted optimizing text adventure

Submitted by Harry Potter on December 20, 2022 - 9:26am

Hi!  I am working on a text adventure for the C64, but, if I succeed, I want to port it to the Apple2.  As it is written in cc65 C and mostly text, it should be easy to port.  Now, I believe myself to be a good optimizer, but I'm looking for more optimizations.  I attached some code snippets from the text adventure.  If you want more information, just ask.

Dallas 1216E "no slot clock" issues

Submitted by baldrick on December 18, 2022 - 11:23am

A few years ago I bought a few Dallas DS1216E clock modules.  Like this:

DS1216E module

They are direct replacements for the original SMT "No Slot Clock".  It goes underneath the CD ROM in the IIe or the CF ROM in the Platinum IIe, and under the system ROM in a IIc.

printtok-002.c/cc65 online: help needed

Submitted by Harry Potter on December 17, 2022 - 11:14am

Hi!  I have printtok-002.c online.  It is a way to print token-compressed strings using my SimpleIO libraries.  It is at c65 additions - Manage /ui at SourceForge.net.  It's pretty good but has two problems: 1. poor compression ratio (it helped a text adventure's text by a little over 25%) and 2.

cc65 prging batch files for Windows/Template Creator

Submitted by Harry Potter on December 16, 2022 - 10:03am

Hi!  I sometimes use Template Creator for Windows to create cc65 build batch files and ProDOS disk images for some of my cc65 programs.  I can publish these online if you want.  Also, I think Template Creator for Windows can help others here to do the same thing.  Template Creator is at tmpcreat - Manage Files at SourceForge.net.  Try it out!

apple iie keyboard or character ploblem

Submitted by heemin828 on December 14, 2022 - 11:02pm

I turned on my Apple IIe today. But the keyboard, which worked well two months ago, is not working a little today. It only enters the same character no matter what key I press.
