Apple Pascal - Switch between 40/80 columns?

Submitted by gmontag451 on May 27, 2022 - 10:17pm

I'm reading through a Pascal adventure game programming book. All the programs are formatted for 40-columns, and I find the 80 column text to be difficult to read on my monitor. Is there a way to switch between 40 and 80 columns in Apple Pascal, either programmatically or preferably through a keypress or menu setting? I can't readily find any reference to this in the manuals.

(If it matters, my copy of Apple Pascal boots into 80 columns, and I've installed the 128k files which take advantage of the RAM expansion.)

Help with unknown California Computer Systems Serial Card

Submitted by GeekDad on May 27, 2022 - 5:43pm

All, 

   I have a CCS Serial Card but it is not the 7710 and I am having a hard time finding any information on it.

   As far as I can tell there is no model number,  on the back all it says is (c)CCS1983, circuit side, made in USA.

    Any help would be appreciated, I would love to set one of //e's up as a serial terminal or use it with ADTPro for file transfer.

Trying to identify my Apple II+ keyboard

Submitted by jrsphoto on May 24, 2022 - 1:39am

I'm in the process of collecting parts to assemble my Apple 1 NTI PCB and I started to think about a keyboard.   I remembered I had an old Apple II+ keyboard in storage so I pulled it out to look at it.   I didn't have my phone handy while typing this but I found an image on google.    The lower keyboard in this image is the keyboard I have.  The encoder chip on mine is labled: TK-10 5732.  To me this looks like an aftermarket keyboard, maybe from a clone, mainly do the removable cover on the caps-lock key, but I'm no expert.

Almost a working IIc, advice needed

Submitted by Nonsensei on May 23, 2022 - 1:54pm

Hey all, an Apple newbie here.

I took up checking my uncle's Apple IIc, that's spent the last 30-35 years in a cupboard.

The computer's actually in a pretty good shape, it's got the monitor, the stand and an external disk drive. All apparently in working order even after all these years. It's a PAL machine with the original 255 ROM.

There are several 5.25" disks in multiple formats. A few original Apple disks and the rest are copies.

Self-Test failure for 80 column card - which chip to replace?

Submitted by monkmaniac on May 23, 2022 - 11:57am

Hey all,

My shiny new (38-year old) Apple //e has a faulty 80-column card. The self-test shows

RAM* 0 0 0 0 0 0 1 0

...indicating that one of the RAM chips is bad. The question is...which one? My desoldering skills are basic at best and I'd like to avoid removing more chips than necessary. Here's a picture of the board:

Apple II Europlus : no boot, screen pattern garbage

Submitted by CedsRepairs on May 22, 2022 - 10:26am

Hello everyone

 

I've solved my first problem on this Apple II Europlus i'm trying to repair ; it used to have a 14Mhz clock (!)

Changing a 74S in the clock generatin made it 1Mhz again, it tok a while to figure to right one as this was not the most obvious one (linked to phase 0) but another one, the 4 bit counter.

 

NOw I have some (pal) video output ; garbage. :(  I've read all topics on this forum about this kind of issue before posting :) Some points to broken links, which does not help.
