Interface ascii apple II+ help

Hello everyone. Could someone help me by explaining how the options for selecting the keyboard type work? I built this board for an Apple II+, put all the JUMPERs (I didn't use a Dip Switch) and it worked fine, but I would like to understand this mapping of columns and rows.Thank you.

OKS Multi-Kache cache

OKS advertised the Multi-Kache cards as having 256k expandible to 1mb.

I was looking at some pics of the Multi-Kache cards and noticed something, 18 and 20 pin RAM.

In the pics one card has HM511000P-10S which is 1mb x 1bit. While the other card has AAA1M204P-08H which is 1mb x 4bit. That seems to indicate that the card can have 4mb cache.

Two Apple ][+ boards with garbage on the screen and no beep! BUT!!!! It;s not the CPU or Auto Start?

Just as the title says. I have two Apple ][ Plus boards (1 rev C, the other rev d) that are currently on the fritz . Both display garbage (or more accurately, the RAM state) on screen with no cursor and give no beep. However, I can state with certainty that it's not the CPUs or AutoStart ROMs, as all have been tested in another working board, and the CPU and AutoStart from the working board have been tested in the broken boards and the symptoms remain with the problem boards.

cc65/Apple2enh: memory configs and ProDOSi

Hi!  If anybody's interested, I have online AuxMemApple and ProDOSi for cc65.  AuxMemApple is a group of alternate memory configurations that provide near-direct access to aux memory, dedicated string and memory functions to use it and usage of unused OS memory, and ProDOSi is a library of functions to use ProDOS almost directly to perform disk access.  AuxMemApple can be found at c65 additions - Manage /memory cfgs at SourceForge.net, and ProDOSi at

Animating images in Applesoft Basic

Hello, per the title, I have this little project where I'd like to animate five 280x192 HGR images with a utility I found from Beagle Bros, Extra-K. It comes with a program called Extra.Screens that utilizes 128k of memory from the IIE and the Extended 80 column card. Attached is the manual with the needed info (pages 26 to ~35).

Forum Observation

I'm new to the Apple 8-bit and new to this forum.  When you first come here the wealth of information is terrifc, with detailed comprehensive threads that are iinvaluable resources.  And it's also a source of much orignal information and products.  But after you're here, the day-to-day discourse is pretty sparse.  Is that normal for this forum?

ADTPro question by barely above beginner

So, I have "mastered" connecting my iMac to my Apple IIe by serial cable/USB adapter, running ADTPro on the iMac, and bootstrapping ADTPro to the IIe.  I have even been able to use the bootstrapping method to transfer disk images to the IIe and create boot floppies of various programs, by placing those images in the ADTPro "disks" subdirectory on the iMac and then doing a ProDos Speediboot, and selecting the image on the IIe.

Unidisk 3.5" Drive (A2M2053) not detected? IWM issue?

Hello hopefully someone can help diagnose an issue with my Unidisk 3.5" Drive (A2M2053) the smart version with onboard cpu is related to its IWM or something else? I suspect it may have been connected to a Mac by po who had mostly mac computers, the issue is it is not been detected by the LIRON card in our IIe? Have confirmed LIRON interface card works and mechanics of the drive function.

 

From my research the IWM in the drive is a PROM (model VLI VF4060-001 344-0041-B IWM PDIP28) can I use the IWM on the LIRON to test?

How to create/use an ORCA/C header file

I have a question about how to create/use a 'header' file on the Apple IIGS using ORCA/C

 

This topic is related to how to create, implement and use a user-defined function in ORCA/C v2.2 on an Apple IIGS.

 

 

The above function works within a program using it as a function prototype:

 

int gotoxy(int x, int y);’

Help with creating an Apple II Disk

Hello,

I'm trying to create a DOS 3.3 disk for my FloppyEmu through CiderPress II or AppleCommander, but it doesnt seem to work. Simply putting the files into an image and using the Emu gives me an error of "File Not Found." I assume the process isnt as easy as just placing files in the .DO disk, so what am I doing wrong?
