Retr0brite

Submitted by insanitor on July 25, 2022 - 2:06am

Hi guys!

My cousin says that using retr0brite on our Apple IIe and IIgs computers depreciates their value. Which means that you'd get more for them if they are yellowed. So, nobody should use retr0brite to make them all look like new if the intent is to sell them.

Is this true? Which would you pay more for?

Apple ii rear cable connector mounts?

Submitted by Thatguyagain on July 24, 2022 - 12:37pm

Hi,  

     Is anyone aware of a source for the connector mounts that fit the cable slots of an apple ii?  Specifically one for a 25 pin connector of a super serial card?  Id like to not have the cable and end whipping around.

Adjust blurred text on GS monitor

Submitted by knight61 on July 23, 2022 - 1:33pm

I saw a  post on here a few months ago in regards to an adjustment for a GS monitor to fix blurred text.  The post said there was an adjustment, but you had to take off the cover to get at it. They also mentioned they had to adjust every once in awhile.  Anyone know about this and where I could find the adjustment setting?  Thanks.Walt

Testing Apple Disk ][ Interface card?

Submitted by gmc on July 22, 2022 - 3:57pm

I've got a Apple IIe which came with a Disk ][ interface card. (With the 2 x 20 pins connectors)

 

I've also bought a Disk ][ Floppy off eBay which was sold as faulty. It would not spin up  and after testing all the chips I found a dead chip on the speed controller board.  Replaced and the drive appears to work in that it does all the right actions, but I cannot read/write any disks.

IIgs RGB monitor collapses to a horizontal band/line

Submitted by inv on July 21, 2022 - 3:23pm

Hi all,

I have an issue on an Apple IIgs RGB monitor (A2M6014), which I recently got.

The problem is: it works well at initial power on, but after some time, the screen starts flickering and collapsing vertically, and then eventually it collapses to a horizontal band (or even to a line). The 10-second video below shows the symptom.

Running teletype with an apple ii plus

Submitted by Thatguyagain on July 20, 2022 - 8:59pm

So i have a unusual project.  I have a model 15 teletype and i would like to try and make it behave with my apple ii plus though an interface board and a rs-232 to 25 pin null cable.  Im using an apple super serial two card set to 300 baud and terminal mode.  I could use some words of wisdom or ideas.  Is there a program made i could try to find or dip switch settings i could try?  Any test ideas to verify my super serial 2 card is even working (total unknown i located it just for this project).  I have located and consulted the manual for the card and think im close.

Advanced Logic Systems (ALS) Smarterm II Documentation

Submitted by brimars on July 14, 2022 - 12:53am

I've been looking around various sources for docs for the ALS Smarterm II 80-column card but haven't had any luck. Does anyone happen to have a copy for sale or one that I could borrow to scan? The Videx card that came with my Apple II+ is dead right now and I'd like to setup the Smarterm card until I have the Videx working.

Thanks! Brian

A2 Europlus : PAL image has green background

Submitted by CedsRepairs on July 11, 2022 - 10:29am

Helloooo girls,

 

Still with my A2+ repair,

I've got my unit "working" (always with this thin vertical lines problem) but now I'm trsting the PAL Encoder card.

 

On both a color CRT and an LCD, the display has a weird green tint background (the black background of text modes is green )

Apart from that the colors look okay in test softwares

 

Is this a know issue ? It knida looks like the display is set too bright but I'm not sure if there is a brightness setting somewhere on the card

II plus upgrade questions (Ultrawarp, RomX)

Submitted by skate323k137 on July 9, 2022 - 10:21pm

I just got my first II plus and so far things are going pretty well.

 

I've upgraded the PSU, and I put in a ROMX. The old ROM under the keyboard was a dianetics lowercase ROM, but I pulled that to install the ROMX completely. Presumably due to changing that ROM, I found intermittent boot behaviour with the mystery card in slot 3 which appears to be a generic 80 column card w/no cables. I pulled the (presumed) 80 column card, and things are pretty good.
