Which Apple II programs are able to use more than 128k ram?

Submitted by RyanM on January 21, 2020 - 1:43am

Is there a list of Apple II programs that take advantage of upgraded memory over the typical 128kb? With all the 1mb, 4mb, 8mb ram cards out there for hobbyists, I'm just wondering what these cards can do for running software. I know some use those cards as ram disks, but I'm strictly looking for answers about software.

Apple IIe PAL - Does not boot

Submitted by nrg13 on January 21, 2020 - 1:31am

Hello!

 

I have an Apple IIe model A2S2064. This has mainboard 820-0073-B, B607-0264-F.

 

This is the PAL version of the Apple IIe, and it's a UK model.

 

I removed the machine from storage, and on initial poweron, the PSU was ticking. I reseated the 80col expansion card, and the machine booted OK.

 

However, when I powered on the machine yesterday, the machine went immediately into the self diagnostics, and reported "KERNEL OK". Rebooting the machine with CTRL-APPLE-RESET starts the diagnostic again.

What is the lower-case modification?

Submitted by Fuji on January 19, 2020 - 4:42pm

I've always wondered what the lowercase/shiftkey modification is. Obviously it adds lowercase characters to the otherwise uppercase Apple II, but how does it relate to my II+ clone? Let me explain.

 

My clone keyboard (partly pictured below) has a lockable pushbutton switch with a red LED in place of the regular "Power" light. In normal 40 column mode nothing happens when you press it, but in 80-column mode (Videx Videoterm card) I get lowercase letters when it's pressed down, and to get uppercase you use the SHIFT key.

Transferring and converting files (II+ to Mac)

Submitted by Fuji on January 19, 2020 - 9:18am

Having had success with ADTPro in audio mode (Apple II cassette IN/OUT transfers) I'm eagerly awaiting a USB to serial adapter (FTDI chipset) for transferring more of my 5.25" II+ floppy disks over to my Mac. I intend to use them with an emulator of some kind (haven't decided on any in particular but have played around with Virtual ][ in trial mode but I know there are others as well.

Vsdrive problem?

Submitted by jlafleur on January 17, 2020 - 9:01pm

No matter what I do, ADTpro from either:

 

Apple //e - Enhanced with SSC

or

Apple //c

 

will boot ADTpro, then VSdrive, then BASIC ... but then go to PRODOS BASIC and not load VSDRIVE.

 

Both give errors when I type in "-vsdrive" one saying something along the lines of "out of range" on the //c and "device not connected" on the //e.

Both load ADT properly, and I can transfer software to floppy.

 

Any thoughts?

Colour output missing (Apple II+)

Submitted by Fuji on January 16, 2020 - 4:49pm

For some reason I'm not getting any colour output from my II+ clone. The monitor (composite input) is attached to the video output on the back of the computer. Other than that there are no other issues with the video (it displays fine, but only in black/white), and everything else appears to work on the computer.

 

So I looked up the Applebox diagram (which illustrates what each IC does) and I've swapped the following ICs, alas without any difference:

ADTPro beginner questions

Submitted by Fuji on January 15, 2020 - 5:04pm

I've got ADTPro (2.0.2/Mac OSX 10.9) working great with my II+ using the cassette ports (it took a while to get the audio levels right, but worked fine after that).

Now I'm ready to move on and speed things up with a USB to serial adapter on the Mac connected to an Apple Super Serial card. I have a few questions:

Hard drive for the Apple II

Submitted by wment on January 15, 2020 - 3:32pm

I have a Corona Starfire 5 hard drive for the Apple II that has been in a dusty closet for over 20yrs. The other day I plugged it in to a IIe and to my suprize it booted. It appears all of the 33 partitions are readable. Wow... Who would have thought. I have a short video that is too big to up load here so I put it on Youtube. If you search for Corona Starfire you might find it.

 

If anyone has any docs or the origional s/w for this please let me know.
