Re: Test equipment

I have a Bitscope Micro. It works GREAT, and their Linux support is pretty good too ( which is improtant to me ). http://www.bitscope.com/product/BS05/ They have other models with more features, and higher prices. But the Micro does everything I need it to do. - Derrik That's a neat little gadget, ...

Test equipment

I'm curious as to how many of you have used the Saleae Logic analyzers. https://www.saleae.com/ I bought their first generation Logic 16 analzyer when I was working on my first microcontroller project. The Saleae logic analyzers aren't the fastest out there, but are a pretty good bang for the buck (...

My Pocketterm is up and running (mostly)

I can see the config screen, but can't test the two serial ports yet because the DB-9 connectors are female.
I need to stop by Frys and get some gender changers.

Re:

Here's multi-maze from Pg. 88. Pretty cool little program.

Re: My 6502 disassembler- not working on the paper tape dump

Uggh From the spec The check-sum is calculated by adding all data in the record except the ";" character. My interpretation of this is- everything between the ; and the last 4 checksum bytes are used to calculate the checksum. However, your definition of a record (above) is that the checks...

Re: My 6502 disassembler- not working on the paper tape dump

Every byte within the square brackets gets added as a 16-bit big-endian sum. If the sum exceeds 16 bits, it was usually allowed to roll over with no carry, though in this case rollover isn't an issue.


Did you add these a nibble at a time, as per the spec, or a byte a time as you've posted above?

Re: My 6502 disassembler- not working on the paper tape dump

Is there a specification for the paper tape dump?

My 6502 disassembler- not working on the paper tape dumps

I'm writing a 6502 disassembler- just for the experience of writing one. I'm using some of the Micro-KIM paper tape dumps from this forum as test cases. I'm encountering some problems with the Battleship game-found elsewhere in this forum. I've noticed that almost all of the lines begin with the sam...

Problem with PocketTerm assembly

One of the pads for the 100 ohm resistor adjacent to the PS2 connector is too close to the metal shield for the PS2 connector. I can probably peel away the shield a bit on the PS2 connector, but I want to find out how others are dealing with this issue. I didn't see any warnings in the manual on how...
