Slots wont work

Submitted by Gary C on May 16, 2019 - 10:48am

 

 I have been getting my spare motherboard up and running over the last few weeks using an old ATX PSU and an arduino to interface a PS/2 keyboard.

Faults so far have been a failed 6502 (address bus all at 3.3V) and one 4116 ram chip (output stuck high) and now the board starts up and works fine. Ran a basic memory test and that looks good, can save and load programs . Loaded and ran galaxians from a wav file through the cassette interface so it cant have much wrong with it.

IIgs image formats

Submitted by BackOfTheBeerCooler on May 13, 2019 - 9:55pm

Anyone know the image format(s) used by DeskMaker for the IIgs? Photoshop (CC version on a modern Mac) seems to be able to convert to most any format, but image size, specific format, etc. seem to be eluding me... I know to RTFM, but where's the manual for this stuff these days?

CCS 7720 Parallel Interface Manual ?

Submitted by tokabln on May 10, 2019 - 7:03am

Is there anybody willing (having the above card including the manual) to scan and upload the manual ? It seems to be that this is not available at the internet.

 

Many thanks

System Saver: Is it needed?

Submitted by machan1985 on May 8, 2019 - 9:45pm

My enhanced Apple //e came with a System Saver cooling fan / surge protector... but I’m wondering if it’s necessary. The ][ was designed to keep cool, and I only have a Disk ][ card and SSC installed in the slots. Is it safe to remove the fan, or do I risk over-heating?

Apple II+ won't boot...displays numbers instead

Submitted by Statsman1 on May 7, 2019 - 3:11pm

Hey guys...

Once again, I seek your wisdom.

I have reseated every chip, and replaced a whole bunch of corroded / blackened chips in a II+, and I'm still basically where I started. 

Power ON

<BEEP>

APPLE II shows up on the top of the screen

DRIVE 0 (in slot 6) starts booting as it does, that reset sound it makes, and then it sounds like it's loading, and just when it starts to load...

...a string of numbers from 5 through 9 prints in a column on the screen (with an occasional 8F in there)...

...and then it stops.

Help with reassembling an Apple IIe

Submitted by gmontag451 on May 7, 2019 - 12:53am

I inherited a disassembled Apple IIe. After a few repairs, I'm almost done reassembling it, save for two problems: 1) The long springy metal strip that makes a connection with the removable lid is not attached to the case. (I believe it's a grounding strip.) I see the scratches in the lid, but I simply can't work out where the strip goes.

Apple Handcontroller //e Issues

Submitted by machan1985 on May 6, 2019 - 6:05pm

Hello, all. I recently received a pair of Apple //e Handcontrollers ( as shown) but it appears there is something wrong with the analog locations. While running Breakout, the paddle twitches and jumps all around. I wrote a small program that outputs the value of pdl(0), and saw that the value will sometimes spike while turning the knob, seemingly at random, but will never be above 244. Additionally, there is a large "dead zone" when the knob is turned all the way to the left... the value stays at 0 while turning the knob to the right a little. What could be causing the issue?

A][e Ram & Keyboard issues

Submitted by KLund1 on May 5, 2019 - 4:58pm

Hello

I have what I believe is standard IIe with just an 80 column, and FD cards

On power up I get the standard Apple II screen. Pressing Ctrl-Reset I get the space bar key repeating. If I press another key then that key repeats.

If I dosconnect the keyboard, and power up I get RAM: in the upper left corrner, and the self test never finishes.

Suggestions of fixes?

Thanks
