Apple II

Advice needed to diagnose Apple ii disk drive problem

I have (or) had a working Apple ii Europlus which I have been using as a benchmark machine to restore a second ii Europlus (my project machine). I arrived at the point where the project machine is fully working and has a Super Serial card on board and has successfully linked to ADTpro. So it was time to get one of the spare Disk ii’s I have working with it. I found that neither of the three drives I have performed as expected and after a little head scratching, noticed that the controller card has a number of chips with ‘black corroded’ legs.

Disk II card ok, Duodisk card not ok

Hi to All,

Would there be any specific reason why an Unidisk card would stop my Apple II from starting up?. (no red power light on motherboard and no screen output, the green power led lights ok though). My II disk card works fine.

Is it just a case of a dud card?

Cheers,

Richard

Pascal differences and manuals

Hi Guys,

I have created the four disk set for Apple Pascal but I get a "no file system.apple" message when I try to boot from disk 1. It seems I am missing a disk or I am starting the Apple up incorrectly. Can anyone point me in the right direction?

I also notice that the disk images were classed as an operating system rather than a programming language so can anyone clarify this?

Ihave since downloaded Instant Pascal and Laser Pascal but I am struggling to find a PDF manual for them. Any ideas?

Colour bleed?

Hi,

I wonder if the composite video output on my Apple IIe (US origin) is too strong for my monitor?

A screen of text is displayed clearly and correctly but the problem lies when color graphics are produced. Blocks of colour show up ok but if there is ant text on the same screen (white letters) there is what I can only describe as random colur bleeding or smudging around the text.

Is this due to an excessive output signal and how can it be lowered or do I need to look at somthing else?

Cheers,

Richard.

Games without Joysticks?

Hi to All,

Being able to create original disks from images is a superb concept, but without user guides for games, I would like to know if it is possible to play them without a joystick but with the keyboard? I realise for most games this would not be ideal but I have not got around to buying a joystick yet!

Thanks,

Richard.

DB-19 Connectors

Hi Guys,

Anyone know where I can buy a DB-19 male connector in the UK?

I've tried a few of the bigger suppliers but no luck.

I need this to make a cable to connect a duodisk to my IIe.

Cheers.

apple ][ (europlus) no characters. beep ok, but only white square no promt.no message

hello
i try to repair an apple ][ europlus.
power supply is ok.
almost all TTL chips new.

if i start up, it beeps once.
but no message shows. no characters at all. only a white square where the cursor should be
i can hit return or any key and the square moves as it should.
also i can type in (blind) a simple programm (forx example 10 print,20 goto 10 ) and run it then the square disapears.
and if i press control c. it returns.

so basic interpreter is working. just no character.
