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.

Apple 2+ No power problem just warm chips

Submitted by AmusedButler on March 27, 2021 - 9:37pm

I have been working on an old Apple 2 plus, got a new power supply and it’s all hooked up. I was trying to test the monitor with computer but no luck and the motherboard was warm, most of the ram seemed warm as well as some rom chips I can get thermal pictures/temperature if needed. Has anyone else had this issue? Is there any way I can fix it? I will try a different monitor but expect the same results.

 

 

 

Thanks in advance.

Apple II+ power issue (not supply) --> Hot chips

Submitted by Stargeezer on March 27, 2021 - 3:37pm

Hi All:

I am still troubleshooting an Apple II+ that appears to work fine w/o periphreal cards but gets wonky video when cards are in and no life in the cards.

I started doing some simple non-invasive assessments.  I discovered I have 2 chips that are getting significantly hot compared to all other chips, one is Apple ROM E0, the other is an SN74S195N.

Two questions:

1) Is this normal for these chips?

2) I have heard about DIY ROM replacements by burning your own on an EPROM.  Anyone done this and had success?

Thanks

mark
