IIc+ internal drive being seen as external! How to change?

Submitted by Word Juggler on August 4, 2019 - 12:25pm

This may be an issue of using System Utilities version 2.1.1 on an Apple IIc Plus.  However, what happens is that it thinks that the internal 3.5" drive is the first external one!

 

For example, I pick choice 7 from the menu:  Identify and Catalog a Disk.  It asks me:  Where is your disk?  The first choice is BUILT-IN DRIVE, but that looks to the attached 5 1/4" external drive.  If it's not attached, it balks, not finding the disk or drive.    I have to select choice #2:  EXTERNAL 3.5" DRIVE for it to read the internal drive!  

 

Weird, eh?!

machine ID?

Submitted by Howard59 on August 3, 2019 - 12:57pm

Hi from an apple novice, who had one forty years ago and put it away soon after... Finally got it  out of store and it all seems to work, (after replacing the exploding PSU capcitor) Question is what exactly is it?

Photos attached - I have the original box importing it into Europe and it says Euro mod plus

The mother board is dated 1978 and is Rev 4

Serial number is 30272 and the board has a sticker with 8020 on it.

the keyboard does not have the open/close Apple keys. The screen comes up Apple][ only

Schematics for a Apple IIe international NTSC motherboard - 820-0188-E

Submitted by mamejay on August 2, 2019 - 1:57am

Hey everyone,

Does anyone have a schematic for a Apple IIe International NTSC board?  820-0188-E

 

Want to know what the solder jumpers are for.

I am in Australia and managed to get a proper NTSC crystal and now have colour on my CRT TV but cannot get colour on my other LCD screens which do support NTSC.

Wondering if the solder jumpers have anything to do with setting the system correctly to NTSC

 

Thanks

Proper cable for ADTPro with Apple IIc+ and MacBook Air? Or, iBook G4?

Submitted by Word Juggler on August 1, 2019 - 2:39pm

            It's been several years since I've done ADTPro transfers and my equipment has changed.  I'm now using a MacBook Air.  What happened was that I discovered that my venerable Keyspan Twin Serial Adapter no longer works with modern Macs.  I'm on OS 10.12.6 Sierra.  I've ended up with several questions.  This gets a little long (apologies for that) as I left in details of what worked and didn't as a help to others in the future.

 

Question 1:  I was wondering if there is a MiniDin8 to USB cable that would work for connecting the IIc+ and the Air.

Apple II plus - yet another scrambled display issue

Submitted by gjbl on July 28, 2019 - 5:25am

Hi everyone,

I have been following this forum for some time now, but this is my first post. Recently I bought an Apple ][+ from an auction site. After some work on the PSU I was able to proceed to the garbage screen phase :-) What happens is:

1) The power is fine, the keyboard lamp lights,2) there is a beep,3) the screen looks as attached, the contents are more or less random, but some 8-column pattern emerges,4) pushing reset on the keyboard does nothing.

14.31818MHz Crystal required - Can anyone help?

Submitted by mamejay on July 23, 2019 - 7:52pm

Hey everyone,

I am trying to convert a couple of Apple IIe NTSC international motherboards to true NTSC.

I live in Australia and as such cannot get colour without replacing the crystal.

I understand that the system was very picky with the crystal and it needed to be just right.

Can anyone sell me a know working crystal or 2?  If so please message me.

 

Thank you!!

Looking for NEC D416D RAM chip

Submitted by mnemonic on July 19, 2019 - 7:11am

Hello,

one of the RAM chips in the middle memory row of my rev 2 is different from the others, which really bugs me when looking at it :-)

Does anyone know where I could source one of the gold ones (NEC D416D)?

 

Thanks for any help,

 

Carsten

Execute binary file on boot-up

Submitted by gobblebit on July 17, 2019 - 8:31am

I have a binary file (asm program) that I've been using AppleCommander to place onto a DSK image, which I can then load into AppleWin. The program runs as I'd expect it to, but to use it I need to "BRUN <program>" from the initial Applesoft prompt. I know that the HELLO program on the disk is executed on boot, and that INIT can place the current BASIC program as the HELLO program and thereby run that program on boot. However, I'd like to run my binary file at boot up as if it were HELLO.

Testing Ram on apple II Plus.

Submitted by NovellNetware on July 17, 2019 - 1:17am

I used the following program.

 

C050 C053 C054 C057 N 265:FF N 266<265.BFFEM 266<265.BFFEV 265:0 N 266<265.BFFEM 266<265.BFFEV 34:14 (Return)

 

came back with serval numbers.  All the original apple chips have some stuff on them. But not down into the pin socketts. Of all strange things. I would just like to replace the 48k total with all new memory due to this. If somebody can point me in the correct direction. I would appriciated it.  The numbers on the chips are tm-s4116-20nl. So Texas instruments 20n ns? chips.
