Apple IIe diagnostic fun...

Submitted by BTDonovan on August 29, 2023 - 8:13pm

Hey everyone... I'm still working on that IIe that I bought late last year and have been slowly restoring.  I wrote a message on the forums back in December or so and got pointed to Joe's for a new keyboard decoder chip and that fixed that problem right away.  In the months that have followed, I have gotten some more gear and setup what, back in the day, would have been an awesome system, but a new set of problems have cropped up int he meantime.  I suppose that I am stuck now, and could use a little advice.

Bluetooth to Apple II – Using an updated Firmware for Option 8’s RetroConnector

 

Over the last few months, I have written a few different versions of firmware for the Joystick RetroConnector (I’ve also mastered making the little device). I can connect Xbox, PlayStation, and most other 8Bitdo type Bluetooth controllers.

Apple II+ doesn't see all the keys from the keyboard

Submitted by DrkStarr on August 23, 2023 - 3:03am

My Apple II+ hates me, or I got a bad one off E-Bay. :/

Currently, the keyboard is not working correctly. The 1 - 2 - A - S - CR - Space - won't type. And you can't do anything without a carriage return.

80 column text and HGR simultaneously in Applesoft Basic?

Submitted by bushnrvn on August 19, 2023 - 7:36pm

I am looking for  information on how to display 80-column text and HGR grapics simultaneously in Applesoft BASIC. I know how to switch between the two, and I know you can do a split screen mode with TEXT and GR, but my goal is to display text where desired on the screen, and a small HGR image in the bottom right hand corner of the screen to fill some negative space. Is this possible?

 

I've leafed through the manuals I know of, but I haven't found a straightforward answer.

Apple II+ Clone (Z80 type) will not correctly boot with the keyboard plugged in.

Submitted by Libnk on August 16, 2023 - 5:31am

I recently picked up an Apple II+ clone, the type with the built in language card and Z80 softcard, and it wouldn't boot at all, only displaying rubbish characters. I replaced some 74161 counters that were dead and installed a modern power supply, and the computer still wouldn't boot. After scrubbing the ROM card contacts and unplugging the keyboard, I heard a beep and saw the BASIC prompt on my television! However plugging the keyboard back in caused the speaker to beep rapidly and a different rubbish pattern appeared on the screen.

InnerDrive

Submitted by Wayne on August 13, 2023 - 3:30pm

My InnerDrive has a WD 93048. I have a WD WD 93048-AD that I tried connecting to an InnerDrive controller, making sure the drive jumpers are the same. The formatter is GSOS. I get part way through booting GSOS when it stops. Tried a different GSOS disk. Tried to format with Copy2Plus with no luck. Also tried a WD 93028-AD drive.

cc65 program w/ assembler & COUT routine: inverse mode only in 80 column mode?

Submitted by Harry Potter on August 12, 2023 - 6:22pm

I just realized while debugging a text adventure that setting inverse mode for text only works in 80-column mode, because the program was printing garbage where it was supposed to print inverse text until I added "videomode (VIDEOMODE_80COL);" to the beginning of the main() function.  I prefer the game to be in 80-column mode, anyway.  I'm wondering why this is.

Two display glitches with cc65 text adventure and A2SimpleIO!

Submitted by Harry Potter on August 12, 2023 - 1:33pm

Hi!  I'm working on a text adventure for cc65 called Adventures on Planet Smir 3, Episode 1.  Right now, only Chapter 1 is mostly written.  :(  I have a C64 version and a Plus4 version online.  If you want, I will give you an URL to them.  Right now, I'm porting the code to the Apple2enh platform.  Now, there are two nasty bugs with the display: the scoreboard is printing the wrong characters and flashing, and the printtok() routine I'm using to print compressed text is not expanding certain tokens properly.  Printtok() accepts tokens as either one character from value #80-$9f and $E0-$FF o
