Apple IIe: switch floppies without restarting computer

Submitted by coolk on April 4, 2021 - 3:04am

Is it possible to stop currently loaded program and start a new one by switching out the floppy at runtime?

I'm using emu to load a tun of .dsk image files on an se card. When I select an image, nothing happens. But if I switch off in that state and switch on again then the program loads. However if I "eject" that image, select a different one and hit empty apple+ctl+reset then I just see apple][ logo and nothing happens.

So my question is, is it possible to load a new program/game without switching the computer off and on?

btw, I'm new to vintage apple computer world.

Testing Disk II without the computer

Submitted by Stargeezer on April 3, 2021 - 5:35pm

Has anyone ever tested a Disk II drive without the controller or computer?

I want to see if there are any electro-mechanical reasons the drive isn't spinning on machine powerup.  This is also to help diagnose slot, vs card vs drive problem.

Apple IIc monitor European vs USA

Submitted by Tomex on April 2, 2021 - 3:51pm

Hello,

I am looking for a green monochrome monitor for my Apple IIc. While searching I asked myself  a question:

since the IIc's composite output is PAL or NTSC depending on region, is there a similar difference in monitor?

 

In other words, would the US monitor work with European IIc (or vice-versa)?

 

I may lack a deeper understanding of PAL vs NTSC, which I understand define color coding, so I thought about asking smarter people.

I recently picked up this Apple IIc and discovered it had a fingerprint board inside which is tapping directly into the CPU.

Apple II+ Mystery Card

Submitted by Paul19804 on April 1, 2021 - 9:03am

Recently acquired a 48K Apple II+ (tagged 8047) with genuine Apple dual-disk controller and an Apple II floppy drive.  It's cleaner than my Apple II (tagged 7847) that I've had since its birth.

It came with an card that appears to be a single drive controller, but testing reveals it doesn't.  The previous owner was vague about the card's function.  Behind the glare, next to the ribbon connector, it is imprinted "Symtec 82"

Interesting side note:  It will fit in the Apple II+ slot, but will NOT fit in the Apple II slot; it's just a bit too long.

Apple II+ PAL -> NTSC mod issues

Submitted by blindowl on March 31, 2021 - 5:26pm

Hi all, 

Since my Apple II+ is modded for the PAL region and I don't have a PAL encoder card, it can't display color. So I decided to restore it to NTSC, but the result is not so successful.

 

As you can see in the video, the display is far too bright and unstable, with visible vertical bars. It is mainly in text mode that the image flickers, in color mode it is slightly more stable (but still too bright with visible bars).

GS/OS 6.0.1 Locks Up loading

Submitted by dougcpa on March 31, 2021 - 3:08pm

I have a ROM 01 GS. I did have an old 5MB SCSI drive on this computer, but that drive died. Instead of replacing with another SCSI drive I've removed the SCSI controller card and replaceed it with a ReactiveMicro compact flash/IDE card installed in slot 7. The only other expansion card in my GS is a 4MB RAM card in the auxiliary slot.

Anyone have success making backup of Avalon Hill games?

Submitted by old_hitech on March 28, 2021 - 9:26pm

I was finally able to get a a working version of Avalon Hill's Tournament Golf. The game works great.  I have not played this game in 30 years. I am trying to make a backup copy with Copy II+ 9.1  on my Apple IIgs and am having no luck. I have tried the 5.25 BIT copy with the Auto Copy selection and TRY AVALON HILL, TRY STANDARD, TRY  STANDARD (ALT. 1), TRY SUNBURST, TRY SYNC, TRY SYNC (ALT. 1)  and all have failed to make a scuccessful copy. Has anyone had any success making a backup copy of any Avalon Hill games?

Trouble Running ProTerm 3.1 on Apple IIe Enhanced

Submitted by JeremyW28 on March 28, 2021 - 3:01am

Hi,

I recently got a WiModem232, and have been very excited to use it with my IIe Ehanced (It was a regular IIe that has been upgraded using the ReActiveMicro IIe Enhancement kit).  I have been hearing a lot about ProTerm v3.1, and it seems to be the go-to terminal program for the IIe, and one that many users of the WiModem232 have had good success with.  However, I have not been able to get ProTerm to run on my machine.
