Apple IIe - strange clock problem

Submitted by LaserMaster on December 4, 2022 - 9:23pm

I've got a US Apple IIe Rev B. 64K MB that is DOA, was given to me.  Gradually I've been troubleshooting why it doesn't initialize.  The PSU is good, power light turns on, voltages are clean and proper values on all filter caps, but no beep on power-up, just a brief flash of about 2" of lines at bottom of Apple  Monitor /// then darkness.  I'm testing bare motherboard, nothing in slots.

1.  On power-up, pin 40 on CPU stays low, it does not toggle low from high and back to high.

Vulcan SSD

Submitted by Wayne on December 4, 2022 - 2:23pm

A while ago I picked up a couple of RAID arrays that used 500gb and 250gb OCZ SSDs. These are older unusually slow SSDs. Slow enough that I don’t want to use them with any modern or even semi-modern equipment.

One thought was to use 2 in a couple of Vulcans. I’ve used CF adapters on the Vulcan cards but not inside the power supply. I connected a IIgs CF to a Mac but of course the Mac couldn’t read it. Vulcans use their own partitioning scheme. I used BalenaEtcher which will copy what’s on the hardware to clone it and it’s partition table onto the SSD.

Selling basic 2e

Submitted by Ratso222 on December 3, 2022 - 8:45pm

Will sell my old 2e with nothing in the slots but an 80 column card. All original chips and everything worked when I last used it last year. I will miss doing the text adventure games (solved all those Infocoms), but I am 76 yrs old and must move on....hopefully not in the "bad sense", but maybe someone can use this baby for parts or as a build. Best offer before Christmas. Hopefully US because shipping can be expensive internationally.

Apple //e color composite monitor help needed...

Submitted by jeff d on December 2, 2022 - 12:14pm

Anyone have advice on troubleshooting a apple model a2m6021? Got no power, I haven't found schematic so obviously prior knowlege will be important. But before the easy electrical stuff I have a physical issue that I can't figure out... it appears the back panel isn't separating from the case when opening it up, is that correct? Shouldn't that powre/control panel stay with the frame  not the case?

Text Adv. Code for cc64/128k Apple2enh doesn't work!

Submitted by Harry Potter on December 1, 2022 - 9:25am

Hi!  I have some code for cc65 around which one can build a text adventure.  It currently works for the C64, the 64k Plus4, the C128 and the 8-bit Atari series.  I've been working on an Apple2enh port.  So far, it works for a 64k Apple2enh but not a 128k Apple2enh.  :(  It uses the A2SimpleIO, ProDOSi and, for the 128k version, AuxMemApple libraries.  When a stub is being loaded, the system gives me the monitor, and the location of the PC is $02C0.  This area is defined by the config files but is unused.  The 64k version works, though.  I am attaching parts of the main module, the stub-load

Looking for ImageWriter II SW2 factory settings

Submitted by mochatea396 on November 30, 2022 - 3:45pm

Hello all,

I have 3 ImageWriter II printers and the manual says do not touch the SW2-5 and SW 2-6 as they are reserved for technicians for hammer strike. I haven’t touched them and all printers work fine. But I just noticed on one of the printers the SW2-5 and SW 2-6 are set oppositely from the other 2 printers. Is there even a factory setting for these or does it vary from printer to printer based on how it was tested from the factory? I don’t plan on touching them I was just curious.

cc65 optimizations online: more wanted!

Submitted by Harry Potter on November 29, 2022 - 3:00pm

Hi!  I like optimizing.  In fact, I have five lists of ten optimization techniques each online.  They are at c65 additions - Manage Files at SourceForge.net.  If you have some good ideas to add to them, please post them here.  I'm currently working on a text adventure for the C64 and may eventually port it to the Apple2 and other 6502-based computers.

cc65 return sequence difference porting from other systems

Submitted by Harry Potter on November 28, 2022 - 1:42pm

Hi!  I am working on a text adventure.  I need to continue it.  I also have some code around which others can build text adventures for cc65.  I have the latter available for CBM and Atari 8-bit models and want to port it to the Apple2enh.  The problem is that the other systems execute a Return in a string as "\n" while the Apple2 uses "\r."  Somebody elsewhere told me about the charmap #pragma of cc65.  What numbers do I need to supply to get "\n" to translate to "\r"?
