Red light on duodisk drive and constantly running

Submitted by JorgeL on October 31, 2023 - 1:19pm

I recently changed the rifa cap on my old Apple IIe and after putting everything back together my duodisk drive is constantly spinning and has a red light on at all times.  

I am pretty new to this, so I am not sure what the issue could be. Before changing the rifa everything worked fine.

Apple II (Not Plus) Board has Issues

Submitted by DistantStar001 on October 29, 2023 - 4:22pm

Recently got a Rev.2 Apple II board.  Originally had AppleSoft ROMs, But the AutoStart had a bad pin (broke off) so I replaced them with an Integer set I had on a II+ board.  The board boots to the Machine Monitor, and with a ROM switch card (AppleSoft onboard) in Slot 0, it will go to BASIC.  I connected a Disk II in Slot 6, and put in a copy of Apple-cillin II.  It loaded fine, so I tried a copy of DOS 3.3, and it either hangs after splash screen or crashes.

MMU problem?

Submitted by afrb2 on October 28, 2023 - 1:36pm

Hi all,

 

I found a IIe in the loft (PAL version) and it does not boot.  Clock phases are correct and address/data lines look OK.  Adr downstream of buffers 74LS244 also look OK and buffers test OK (in an LED & switch tester!). There is no beep.

Apple /// ROM Adapter and Custom ROM Project

Submitted by MacFly on October 28, 2023 - 11:36am

I wanted a reliable and easy to use adapter for the Apple /// system ROM ("B9 ROM"). Something to plug standard EPROMs & EEPROMs. I want to make a few ROM extensions - making use of the second ROM bank, which was orignally unused. Apple only installed 4KB ROMs, though 8KB were supported (split into two banks) - but the unused second bank just returned random data. Maybe Apple intended this to be used for future updates. But we all know that never happened...

AdvSkel65 progress report but bug still there

Submitted by Harry Potter on October 26, 2023 - 5:10pm

Hi!  I just replaced the version of printtok used with AdvSkel65's no hidden memory C64 port with a newer version of printtok, disabled some at-first-unneeded code and bought .11k.  I need to continue upgrading AdvSkel65 now.  But the bug is still there.  :(  BTW, I am using an old version with Smir 3, 1.  It's going to take a lot of effort to upgrade Smir 3, 1, as the whole mechanism with handling tokens changed.  :(  Now, tokens are in the range 0x80-0xFF, while in older versions, some tokens start with a '%' and are followed by a letter or a number.  I'm using Notepad++ on a Win11/64 lap

AdvSkel65 doesn't work on 128k Apple2enh

Submitted by Harry Potter on October 26, 2023 - 3:24pm

Hi!  I've been heavily optimizing and improving my AdvSkel65 program.  Right now, I'm preparing the latest version of PrintTok for my codes, and this version supports up to 128 one-byte tokens and more text adventure-related control characters, including tab and clear screen.  However, the 128k Apple2enh version gives me an error #67 while loading a stub into memory.  The 64k version shows no problem, and neither do the other ports.  I suspect stack corruption, as that happened to me several times before.  I attached the ProDOSi code to open files and read data and the code's main file.  If

MII: New IIe open source emulator, mine this time!

Submitted by BusError on October 25, 2023 - 3:57am

Monochrome Double-Hi res

This has to be the worst case of feature creep in history, I wanted to hack an emulator for one specific project (Testing a Dan ][ card tool!) and couldn't find something I liked enough -- so, I wrote my own! So here it is, MIT licence. Tons of stuff work, a few bits needs work, but it's perfectly usable as is already!

Funny thing is, I haven't even started writing the Dan][ tool I wanted, but I no longer have an excuse now -- procastination at it's best!
