Apple II Early Disk Files

Submitted by wsander on July 14, 2020 - 4:16pm

I have updated my web site apple1notes.com (moved from the old iWeb to Wordpress) and I have added about 40 Apple II .dsk files.  These are mostly early programs from 1977 to 1980 and mostly Integer Basic.  They are primarily of historic interest and show the kinds of programs early Apple II owners were writing before there was much commerciallty available.  There are some early programs by Bill Budge, Bill Adkinson, and Bob Bishop.

Imagewriter II Issues/Questions

Submitted by nick3092 on July 11, 2020 - 5:02pm

Not sure if this is the best category on the forum to place this, but seems to be the best fit.  I'm having two minor intermittent issues, and one of them seems to vary from print to print on how noticeable it is.  As a kid I had a different printer (its boxed up in my basement, and the name escapes me right now.  But I couldn't find printer ribbons anymore.  I was surprised to see I could still get IW2 ribbons and tractor feed paper, so I picked one up a couple months ago for a decent price when I started getting back into using my Apple hardware.

Ticking sounds from PSU

Submitted by pcbastler on July 10, 2020 - 4:33pm

OK, my friends... next day, next problem :( - It seems as I should not get my II europlus to work :(

 

After recapping the PSU I get a ticking sound (about twice a second) from it.

At every tick all voltages break down an build up again. It seems as a cap charges and then discharges in an electric arc... but I cannot see any arc.

I also was not able to localize the tick exactly.

 

Any clues on that?

Utopia Graphic Tablet System software for Apple Graphics Tablet

Submitted by macnoyd on July 9, 2020 - 3:34pm

Does anyone have the software "Utopia Graphic Tablet System" software for the Apple Graphics Tablet?

This was written by the now famous Todd Rundgren back in the very early 1980's.

Anyone know where I can find it?   I've looked everywhere.   Thank you in advance.

Is anyone making clones of Apple II disk controller cards?

Submitted by CheshireNoir on July 9, 2020 - 7:40am

Hey All,

Is anyone making new "clones" of any of the Apple II disk controller cards, in particular the Disk II Controller card (The one with two sets of pin headers for the original Apple Disk Drives) or the 5.25 Controller Card (the one with the 19 pin D connector attached)?

Rather than buying something of unknown vintage, I'd prefer to buy a recreation, if anyone is making them. 

I'm aware of Yellowstone and the ReActive Micro cards. Both seem overkill for what I need.

(I have a set of Disk II Drives and a DuoDisk with nary a controller card between them)

ROM checksum error

Submitted by tony359 on July 9, 2020 - 5:55am

XPS says that my C0 and E0 ROMs are failing checksum check. Should I be concerned about that? I have an eeprom programmer if that helps - but I would need an UV lamp! :)

Is the Apple II+ horizontal sync width ~8us (for all revisions? ? I think some modern TVs cannot sync'd to the Apple II video because of this.

Apple II SchoolBus Cardq

Submitted by 8bit_SchoolBus on July 6, 2020 - 3:22pm

Hi There, 

 

A couple years back I picked up an Apple II "SchoolBus" networking card, made by Apple. According to the promotional literature I was able to find, it looks like it allowed several II/IIe's to be daisy-chained together and share a "server" Apple II and share a Disk II and software. Essentially a teacher could "push" programs to students to work on, similar to teachers using Google Classroom, etc, today.

Strange issue with MECC games - none will start

Submitted by shadmere on July 6, 2020 - 4:03am

I'll admit that I don't really know what I'm doing.  But because of that, I'm not quite sure where to start!

 

I just got an Apple IIe (unenhanced).  Obviously, the first thing I wanted to do was to boot up some old games I remembered from childhood.

 

Every time I try to play a MECC game (Oregon Trail, Odell Lake, Number Munchers, etc), the system loads the title screen with MECC logo and . . . stops.

 

Nothing else happens, no matter what buttons are pressed.
