But the entire screen is green with a flashing cursor.

 

I type in anything , hit enter get a beep

 

Cant see any characters - Just a green screen with a flashing cursor

 

the direction keys work

when i boot it up with the disc drive card installed it boots a game ( choplifter screen) but then freezes.

Apple IIe USA Motherboard in Apple IIe Pal case+Powersupply

Submitted by robbo007 on February 25, 2020 - 7:21am

Hi all,

Is it possible to use a USA Apple IIe motherboard with a Apple IIe Pal Powersupply and case?  I gather all apple powersupplies step down the voltage to something less than the 240V (in the PAL version) or the 110v ( in the US) versions right?

 

I'm thinking aobut replacing my Apple iie pal board thats blown with a USA one off ebay.

 

Thanks,

Rob

Trio-Disc

Just an assembly of assorted parts into a coherent unit for my CloneE.  Switch selectable boot device either floppy, or floppulator. Plus  a second drive mounted like a duodisc.

 

Switcheroo the device select, lets you hook two items to one Disk II channel and switches the device select

Apple II Disk Drive After Reset

Submitted by gobblebit on February 20, 2020 - 6:37am

I've been tinkering around with an Apple II emulator after writing an NES one (they share 6502 processors) and have it reading disk images, displaying graphics, and generally playing whatever games or software I throw at it. One difference I can't explain however has to do with the boot-up sequence and how it interacts with its disk drives.

I have an AP-64e Eprom programmer, and want to do a test on my Apple II+ (64K)

Is there any software for this card ,(Disk.dsk) or this card only uses the program inside the eprom  ?

Thank you very much!

Apple II crystal question

Submitted by Corey986 on February 17, 2020 - 5:30pm

OK so I'm working on this Rev-0 board and I think it was modified for PAL.  I don't own a euro system so I have nothing to compare it to.   I removed a whole load of jumpers and other crap on the back and repaired some cut traces.  I got weird video out of it, so I checked the crystal and it was an M-TRON 14.25045 MHz which is wrong for NTSC.

 

I replaced it with a spare no-name 14.31818Mhz crystal but still messed up video....

//e enhanced that won't run or list

Submitted by MajorMar on February 14, 2020 - 10:17pm

I recently acquired an Apple //e Enhanced that had only a few minor issues, or so I thought. It only has a disk controller card in it and I did find one bad ram chip which I replaced. However, for some reason, I cannot run the commands "RUN" or "LIST" in either the built-in basic or ProDOS. I can load programs from the disk drive just fine but can't run any basic programs. I haven't found anything yet in my searches to point me in the right direction. Has anyone seen this before?

Early Apple II (Silver) power supplies and load for testing

Submitted by Corey986 on February 14, 2020 - 5:40am

So I am restoring an Rev-0 Apple II supply for someone. I was told it wasn't working and It was missing the power connector, so I replaced that. I opened it up (it already had screws, I know older supplies were riveted). Visually everything looked good, nothing leaking or bulging. I checked the fuse.

OK basics done before I dig into real troubleshooting.
