How to affordably play Doom?

Submitted by Caden Nyholt on February 18, 2025 - 1:44pm

I would like to run Doom on my Apple IIe. However, Doom floppies are upwards of $1000. Is there a legal and affordable way to play Doom?

AppleWin: screenshots?

Submitted by Harry Potter on February 16, 2025 - 7:08pm

On my Win11/64 laptop, at startup, AppleWin complains that it can't trap the PrintScreen key.  I believe it's because I have Greenshot installed on it.  I don't use it but may eventually find use for it. It doesn't do this on a Win7/64 laptop at my day program.  I tried the key there and didn't see anything.  I don't know if it did it silently or ignored the press.  I'd better check the game's folder, as it was on a flash drive.

Apple IIe (PAL) Power Supply Repair

Submitted by khvtechsurrect on February 16, 2025 - 9:13am

Typically I tend to refurbish (read about the RIFA capacitors...) or getting new additional power supply to my various system, but since I just received my Apple IIe (PAL-version) 2 days ago I just wanted to quickly fire it up and test it and believe that after good 15-20 min I saw the smoke from the power supply and simply turned off the computer.Unmounted the power supply to check the pcb to find the RIFA capacitors and looking of the whole pcb by itself didn't really show any thing:

Apple ii Europplus - Expansion slot issue

Submitted by lemonypye on February 13, 2025 - 8:31am

Hi Folks,

 

I have recently aquired a trip back into my childhood and have a lovely Apple II Europlus with 9" B&W monitor and Disk II controller with drive.

 

Everything seems to work ok and as expected, until I plug any expansion card into any of the slots.  The Disk II controller can plug into any slot, and all works as expected.  However, if I plug my A2DVI card or a 16k memory expansion card (In to slot 0), then the computer just doesn't boot.  There is no beep, and the disk drive doesn't spin.  In addition the screen just displays all white squares.

SmartDiskII card

Submitted by softwarejanitor on February 8, 2025 - 6:44pm

I built 5 of these over a year ago and then never really did anyything with them because I got sidetracked on other projects, which happens a lot.

 

Anyway, I was trying them with VIBR's disk emulator board using the latest v0.80.1 firmware and I have the board set to SmartPort mode, the image selected all connected to a regular Disk II controller.

 

But when I hook it to one of my SmartDiskII boards it doesn't appear to get any power.  It doesn't boot, if I try PR#5 (or whatever slot I have it in) , it says "NO DEVICE ATTACHED".

Applied Engineering power supply resources

Submitted by mahvha on February 6, 2025 - 5:21pm

Can anyone point me towards some resources to trouble-shoot what I believe is an Applied Engineering power supply? I've had a fair amount of success saving Apple-brand power supplies, but the AE model is a completely different animal in terms of components and complexity.  It's a black box, shorter than the Apple models, labeled Model PS-A, has a 120/240 external switch secured with a plastic tab and is rated +12V 3A, +5V 6A, -12V 1A and -5V 1A. It came with a lle which ran intermittently and then gave up the ghost. No obvious sign of component failure, no cloud of smoke and no stink.

Did anyone analyze the IWM related Apple IIc firmware ?

Submitted by UncleBernie on February 3, 2025 - 4:03pm

Hi -

 

I'm making some progress with my "IWMless" project but to proceed I'd need some hints about what the Apple IIc actually does with the IWM, other the "default" configuration it has on power up (basically, in this configuration, the IWM has much the same behaviour as the DISK II controller, but with a few subtle differences regarding disk write operations and the write protect sense).

 

But where I'm stuck right now is the yet open question which other configurations of the IWM does the Apple IIc use ?

Classic ide firmware

Submitted by Wayne on February 1, 2025 - 5:30pm

I have a Technobytes Classic Ide card that has a problem. I’m wondering if a firmware update might solve the problem. However I can’t seem to locate a firmware update. Does anyone know where I might find it?

Any Apple2-native C users out there?

Submitted by Harry Potter on February 1, 2025 - 4:38pm

Hi!  I've been creating a special program for Super C users from the CBM community, but it was cancelled due to lack of interest.  :(  I really enjoyed it, too!  :'(  Is anybody here an Apple2-native C programmer?  I don't want to tell the nature of this project; I just want to know if anybody here is in the program's audience.

cc65 text compression: PrintTok

Submitted by Harry Potter on February 1, 2025 - 4:10pm

Hi!  I have a text compression program for cc65 and its CBM, Apple2 and Atari8 targets called PrintTok or PrintTok1.  The CBM community rejecgted it, and I have yet to try Atarians, so I'm coming here.  PrintTok is a program to print out strings compressed using tokenization and helped out the C64 version of my Smir 3, 1 text adventure's database file by about 43.1%.  Its current issues are that it doesn't compress literals and doesn't support automatic compression.  I'm currently working on PrintTok2, but, even though I got it to work several times, the compression ratio was poor.  :(  If
