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.

Making 5.25 Disks--Follow Up

Submitted by nd2003grad on July 7, 2022 - 7:06pm

Hi All!

 

I posted a while ago about making Apple IIGS disks in general and have basically solved that problem with what I have.  I have an unusual setup in that I don't have a Floppy Emu, I have a prototype smartport device that is capable of 4X32mb HD images and that's about it.  So, to make 3.5 disks I merely converted the images to .po and then copied in GS/OS.  Worked like a charm especially for games that need to run from startup or don't work from HD image/aren't present on HD images for some reason.  So, great--that worked.

DOS 3.2 issue solved (Now on 16 sector disks)

Submitted by mochatea396 on July 7, 2022 - 2:03pm

I decided to post a new thread on this subject rather than going to the bottom of my old post and adding to it.  I have attached 2 files that I made which are DOS 3.1 and DOS 3.2 system masters on 16 SECTOR DISKS. These images can be written with ADTPRO like you would write any other 5.25 disk. Both have been tested in my integer basic Rev0. Since they are integer basic disks they will NOT boot in a iie.

Random question about Super Serial Cards

Submitted by profdc9 on July 7, 2022 - 11:19am

I have a question about Super Serial Card support on software such as ProTERM, Ascii Express, Agate, ADTPro, etc.

Does the software use the ROM on the card, or even check for the ROM on the card, when using the Super Serial Card?  Most of the logic on the SSC is to handle the paging of the ROM banks, and if the ROM is not needed for most software, a vastly simplified card with just a 65SC51 and line drivers could be used.  It seems to me for software that has its own drivers the 65SC51 registers would be accessed directly and the ROM would not be necessary.
