Altera MAX 7000S series strange LCELL behaviour

Submitted by frozen signal on May 4, 2024 - 10:08pm

Though this is not strictly Apple II related, since the Altera Max 7000 series CPLD is popular here, I feel I have a duty to warn.

I can't find the exact quote from UncleBernie, but I remember reading him telling about "in his days" people having their expectations about CPLD/FPGA being 'reajusted' by reality. The last couple of days have been such days for me.

Replace HAL chip -Apple IIe Plat?

Submitted by kent5 on April 24, 2024 - 2:20pm

Hello all,

 

I'm new to the AppleII world, and am trying to resurrect an Apple IIe Platinum, but am having an issue.

 

The problem is that the machine boots fine when cold (and is able to run some very simple BASIC  programs), but in a few minutes after startup, it freezes.  Rebooting at that point brings up "Apple IIe" title screen but NO command prompt.  Once I let it cool for an hour or so, it boots normally again.

OS9 Editor and C-compiler

Submitted by jbforrer on April 23, 2024 - 12:11pm

Greetings,

Now that I have built up and have my 6809 Co-processor running,I'd be grateful if anyone can point me where to obtain the EDIT and C-Compiler software for Apple II OS9.The OS9 images from the Asimov archive are missing those parts. I assume it was not in the original distro.

I'd also appreciate suggestions how to transfer software to and from OS9 system.I'm aware of Luca's github page descibing the Os9-Conv_Tool.Perhaps someone has made efforts to do this.Thanks in advance.

IIc RAM Troubleshooting

Submitted by DigitalNZ on April 23, 2024 - 5:44am

Hi All,

 

Apologies in advance for yet another Apple IIc RAM related post! Bit of a story for background and what I've already tried doing. 

 

Background: 

About a year ago, I bought myself an Apple IIc on TradeMe, a local auction site here in New Zealand. While I've got a rather large decent sized Mac collection, this was my first venture in to the Apple II lineup.

A2 Term power mod

Submitted by Wayne on April 23, 2024 - 1:58am

I’ve never had a need of the term power mod on a Apple II SCSI card but now I have a situation where it’d be handy. The diagram for the Rev C SCSI card says to connect the diode to the front end of C16. I’m thinking that they meant C18 as C16 is on the far end of the card.

Apple IIc That Ram Test Runs Over and Over

Submitted by KLund1 on April 21, 2024 - 1:15am

I have a IIc that now has a ROM4x installed. It previously has a 255 ROM.

With the keyboard unpluged, and then powered on, the Ram test starts.

But is never finishes. The System OK message does not appear. 

Before this, there wer 3 bad ram chips I replaces with sockets and previously testing good ram chips.

When I plug in a good keyboard and then run the Ram test, I get the System OK message.

Do I need to worry about this?

Thanks

AIIc Floppy Drive Door/Latch/Lever wanted

Submitted by KLund1 on April 21, 2024 - 1:08am

I have another AIIc with no gray/tan FD door/latch/lever, and no spring

Does anyone have an extra they would be willing to part with for a reasonable price?

Or is there a store site that might have them?

None currently showing on evilbay.

If this is the wrong forum for this type of request please let me know.

Thanks
