IIe drive in a IIc

Submitted by Statsman1 on October 13, 2022 - 4:28pm

Hey everyone!

Wow, it's been quite a while since I was here!  Hope everyone is OK, survived COVID as well as one could hope, and still enjoying the hobby!

So I have a IIc that I have taken out of the battered IIc case and would like it to run a longer disk drive cable.  I believe that a Disk II cable will work, and it certainly seems to work just fine.  However, the Disk II ALSO works (not just the IIc drive), which I found fascinating, though that is likely old news to you pros.  :)

EMCO Joystick

Submitted by nick3092 on October 11, 2022 - 8:32pm

I picked up this EMCO brand joystick a little while back in a lot of stuff, and can't find much information about it.  It's a dual Apple/IBM joystick, with a switch on the bottom.  Then there are 4 pegs that look like some kind of adjusters sticking out of the bottom.  They aren't for centering/trimming though, as those adjustments are on top of the stick.  The pots measure just shy of 1Meg across, which seems odd to me.  And the switch for Apple/IBM mode seems to switch in or out 2 resistors.  I didn't have time to trace everything out to see exactly what is going on.  The stick seems to w

Incomplete joystick range for Y axis

Submitted by deltamind106 on October 11, 2022 - 1:51pm

I just picked up a new vintage (1983-ish) apple IIe branded joystick.  The joystick seems to work well, but I'm only getting partial range for the Y axis.

The X axis is good-- I can adjust the center to a value of 127, and pushing the joystick full LEFT goes to 0, and full RIGHT goes to 255.

Alternate ROM image for TJBoldt ProDOS Rom Drive (ProDOS 2.4.2 + utils)

Submitted by skate323k137 on October 10, 2022 - 9:58pm

I've put together an image which I am still working on, primarily for my II Plus, which contains some useful tools. Right now the starting point is the ProDOS 2.4.2 disk from John Brooks' website:https://prodos8.com/releases/prodos-242/

Combined into the Blank drive with firmware file provided in TJ's repo (https://github.com/tjboldt/ProDOS-ROM-Drive) I pieced it together using the instructions for Bitsy Bye (again, from John Brooks' website).

ProDOS STARTUP menu - trying to work out how this code works

Submitted by gmc on October 10, 2022 - 4:41pm

I'm busy teaching myself all about the Apple II and starting off with  a ProDOS ROM image written by Terence Boldt

 

Looking at the STARTUP code in CiderPress, it uses Applesoft to print a menu and then loads a game depending on which key you press.  

I've worked out most of the simple basic commands but what is stumping me is how is the game actually loaded. 

I would think there should be something like LOAD game? 

 

The code reads the key pressed and sets a variable GAME = 0 to 26 (Depending on which key is pressed) Then the below routing is run.

Weird 5.25 Apple Drive issue

Submitted by schafferm on October 10, 2022 - 12:10am

Hi

strange issue with a Apple 5.25 drive.

 

 Testing on Apple-Cilian the drive passes all tests including read / write / format and disk speed calibration.     

As the 2nd drive I can perform all functions.   However as a boot drive it will not cycle through a normal boot and boot up a disk.   

I've used 2 different Apple computers, I've used two different controller cards.   Still this drive is acting up.  When I replace with a different drive that drove acts as it should

 

any idea on what I should check next?

Weird No-Slot-Clock issues

Submitted by baldrick on October 9, 2022 - 11:12am

Several years ago I bought a number of Dallas DS1216E modules from AliExpress.  

The DS1216E is functionally identical to the SMT No-Slot-Clock.

After a bit of surgery to grind out the epoxy underneath it and disconnect the internal (dead) button cells, I connected some modern CR2032 cells to each of the chips via some leads and a coin cell holder.

I had four working No-Slot-Clocks as a result in 4 different machines.  One of them runs 24-7 hosting a BBS.

The other three were in machines storage with the power cells disconnected.
