i dug out an old ITT 2020 (apple II for europe before the europlus came out) from my dads collection of old computers.
After reseating some chips it boots just fine and basic basic-commands work.
However i can't load games from http://asciiexpress.net/gameserver/
I hear a beep at 4s of the hifi or lofi audio file but when it reaches the 9s mark i getERR ?Syntax Error in 49352
for the hifi file andERR ?Syntax Error in 803
for the lofi file
listening to the audio files this seems to be the end of the first data block befor it goes to a short sin sound again.
So i'm completly new to the apple 2 and have no idea where to look for a solution xD
The ITT 2020 was not 100% compatible with western software. For one thing, it ran on PalSoft BASIC, so AppleSoft BASIC software may fail, particularly for graphical instructions due to the different bit width used for the PAL video.
Integer BASIC software may fare better.
The ITT disk drives and controller are also only viable for 13-sector diskettes. We had one of these back when they came out. (I frankly wouldn't mind getting one again for its nostalgia.)
I am uncertain if the genuine Apple II 16-sector cards work in the ITT 2020, if you were to scavange one from a EuroPlus.
Grab some casette images here, to test the system:
P.S., Moderators: It may be prudent to add an [ITT 2020] flag to this topic title.
Thanks for the link,
final found time to test it.
The integer basic casset did work. So there is no issue with the casset-in.
Is there an guid on the internet on what is and isn't compatible?
The dreagon maze casset for example didn't work. Does it need some extension? (only one of the extension slots in m itt is actually populated)
Please be more specific than 'didn't work'. Once you load it, use the LIST instruction. That will show you all of the instructions if it is a BASIC programme. (You will need the monitor / prog aid if it is not.)
Most tapes would in general only have a RAM requirement, and AFAIR, none need greater than 48K. If they are written in integer BASIC or AppleSoft BASIC, your ROMset is what makes the difference. Tapes use whatever BASIC you hae installed in ROM or that you load via a language card (if available).
Please post a photo of what is in your system slot, if you would like me to identify it.
If the actual LOAD instruction fails, then the cassette may be bad/damaged, the volume slider not at the right setting, or any number of factors. The actual ITT-2020 cassette 'images' should all work.
Keep in mind that there are a number of differences betweeen the ITT-2020 and an actual Apple II or ][+, and the later Europlus. These are porrly documented, especialy given how brief a period the ITT-2020 was on the market, that it was replaced by a genuine pple product, and that a number of developers in PAL regions used the NA Apple ][ systems to ensure compatibility/colour for a worldwide market.
When i tried to load the dragon maze image it displayed errerr after like 5 seconds or so and gave me a command promt again.
I currently don't have it at hand, it will be some time till i can look into it again. (I'm currently fixing up the next pc from the collection, an old ms dos pc)
But thanks for the help again ^^
Try adjusting the volume. What is your output stream source?
Laptop, mobile, actual cassette deck?
