Murder Party Decoded!

Submitted by gmontag451 on February 5, 2023 - 12:32am

I've finally completed my write-up about my exploration of Electronic Arts' Make Your Own Murder Party data disk, as well as an explanation of how the data is decoded by the software. The complete decoded text, my explanation of how it all works, as well as the program I wrote to decode the data can be downloaded here:

(By the way, I'll update the other thread about the Murder Party printing issue sometime soon.)

 

Here's a brief synopsis of my observations and decoding tutorial:

Apple Independent Developer conference(s)? 1983

Submitted by skate323k137 on February 3, 2023 - 7:16pm

Hey all,

 

A neat letter showed up in a pile of Apple II docs I was sorting. It's is a letter thanking someone for having attended the independent developer conference in April 1983.

 

I looked into the conference just out of sheer curiosity, and found several references to a 1983 independent developer conference, but, that one happened in August 1983, several months after this letter. I can find no refernece to a conference earlier in the year. 

 

If someone wants me to scan the whole thing let me know and I'll pop it out of the frame I have it in.

Grappler vs Grappler+

Submitted by djc6 on February 3, 2023 - 2:00pm

Anyone know the difference between the Grappler and  Grappler+ cards? 

I'm curious because I'm looking for a parallel printer card for use with a NEWPRINT device on my ROM3 IIGS, and some claim Grappler compatibility but I've not seen any claim Grappler+ compatibility.   This article claims the IIGS is picky about its Grappler+ cards - seems you want a model where chip U10 is a 74LS374

How to 'steal' sprites from Apple II games ?

Submitted by UncleBernie on February 2, 2023 - 12:42pm

During development of a graphics card for the Apple-1 I ran into the problem to procure some nice looking on-screen figures found in Apple II games for demo purposes. Alas, the process using a real Apple II (clone) is too tedious, it takes me about 15 minutes until have a a captured screen image on my Linux machine to work on it, only to find out it was taken while the screen buffer was incomplete (software still drawing the 'sprites' or the fixed objects). So I moved to AppleWin-1.30.12.0 emulation where I have the debugging console.

How to test a Cirtech plusRAM card

Submitted by martind on February 1, 2023 - 4:02am

Hi,

 

I have a Cirtech plusRAM card with my Apple II, I believe it is a 1 meg card with an additional 1 meg on-board.

I would like to check the card is working but I'm unsure of what I can do to show the additional RAM in the system.

I've tried running Apple-Cillin and doing a RAM test but it does not appear to detect this type of expansion card.

Any ideas would be greatly appreciated.

ProDOS directory sorter (not CAT.DOCTOR)?

Submitted by cryu on February 1, 2023 - 2:05am

I've been using CAT.DOCTOR to sort the root directory on my ProDOS floppy boot volume, to specify which particular system files are loaded.

 

However, CAT.DOCTOR appears to be incompatible with Dan's Apple2Card.  I'm not in front of my Franklin at the moment, so I can't report the exact error that it throws when I try to read in the root directory -- but it does bomb out.

 

Before I start reverse-engineering CAT.DOCTOR, is there a workalike that I can test to see if it works?

I will preface this by saying I'm not trying to rant at anyoneor be rude (and I apologize if it comes across that way), I'm just trying to be as precise as I can be with my question; I'm after a very specific thing.
