Need Help With Apple IIGS Memory Error

Submitted by Ahow77 on December 31, 2019 - 4:44pm

I have a rom 1 IIGS with a 4mb expansion card and I'm trying to get a music program called Sonix to work with it. I'm using Floppy Emu rev B to load the image. I get past the initial ProDos 8 title screen then it shows this memory error:

"Allocate 0101
***MEMORY ERROR***
Must be user #1
De-allocate all managed memory "

Then it gives me a command prompt and I don't know how to proceed. Any help would be appreciated.

* SC-02

* Arctic-02

* SSI-263P

* SSI 263AP

* 78A263A-P

 

any pointers would be appreciated, thank you for your time.

Getting a DuoDisk unit working again...

Submitted by joel_graff on December 28, 2019 - 3:23pm

I came into posession of an Apple IIe with a DuoDisk unit.  It sat for years in a barn and is caked with mud dauber nests on the inside.  As I'm cleaning it out, I've torn down one of the two DuoDisk drives and I want to establsih two things:

 

1.  Whether or not I need to do the DuoDisk mod to the analog board

2.  How to test the stepper motor before putting everything back together.

Apple II Plus Power Supply Failure

Submitted by Samuel Pickwick on December 28, 2019 - 2:03pm

I powered up my Apple II Plus for the first time in probably over a decade last night (which I bought new in 1980). After running for a while a burning odor was detected; I shut off and uplugged the unit, removed the cover, and detected a thin stream of smoke coming out of the power supply. Is there a list of compatible and available new supplies to be used as a replacement? I was going to survey the damage but could not easily/quickly remove the p/s cover, it seemed like it was welded shut.

I appreciate any advice!

Thanks.

Apple ][ europlus PAL card issue.

Submitted by CheshireNoir on December 28, 2019 - 5:47am

Hi All from this Oz Apple II owner.

I've just got my first Apple II. It's a Europlus, with the Language card in slot 0, an I/O disk card in slot 6 and a PAL card in slot 7.

 

I've got the disk drives working (Had to make a 19 to 25 pin adapter as that had gone missing) and I've fixed the bootup garbage issues it had (It was the 6502 of all things! I popped it out of the socket while looking around for faults and the pins were black. Some Deoxit and a hard eraser fixed it up a treat) but my Google-Fu is failing me with the final issue.

PC Transporter - IIe Keyboard Adapter

Submitted by Moonferret on December 26, 2019 - 6:18am
Hi Folks! I've recently aqquired an AE PC Transporter. I've managed to get it running just fine in my IIe but I have to use an external PC keyboard. There is an adapter that allows the use of the internal IIe keyboard but I am missing this part. Does anybody have one or even a schematic for the board (Looks to be pretty simple) Here is a photo of a Transporter. The board in question is the one in the top left.

RIP Chuck Peddle: Father of the 6502

Submitted by MacFly on December 23, 2019 - 4:42pm

Sad news - only saw it now: Chuck Peddle, the "father" of the 6502 CPU, has died:

https://wdc65xx.com/in-memoriam-of-chuck-peddle/

 

With his idea to create an "ultra-low-cost" 8-bit CPU (for only $25), creating a whole new market for personal/low-cost computers and the business of mass-producing CPUs, he has certainly permanently changed the world - for the better!

 

So, switch on your Apple //s (and ///s) and make "his" 6502 spin for a few extra cycles in his memory!

 

RIP

Apple IIc Plus video problem

Submitted by phoenix1031 on December 21, 2019 - 9:34am

Hello, I recently got this apple IIc Plus. When I turn it on, the screen shows characters in red/blue color instead of white.

It sometimes shows white characters, but after a few seconds, it switches back.

How can I fix this? Please help me.
