That's good. It really is a big improvement over the earlier versions. I haven't been working on it at all recently, since the only features I'd like to add will all be very difficult to squeeze in. But one little extra I may put in is a change to the single step function so it will not stop inside ...

The paste code I put in POM1 is a bit dodgy I'm afraid. The problem is that it is not linked to the emulated Apple 1's reading of the characters, so it just tries to do it suitably slowly. This is fixed in the emulator version inside the Krusader Toolkit, and I would recommend using that. (It also s...

It can run from RAM, but you will need to reassemble from the source. Just set INROM = 0 and it will assemble to $7100 (the complete memory model is described in the manual). The RAM version does not include the minimonitor, and the assembler I use is mentioned on the first page of the manual. For t...

$D0F2 is wrong. This code is checking an I/O address, as described in the Apple 1 documentation. $D012 is the appropriate value. I don't know what address decoding is in place on the original Apple 1 board, so it is possible that the high order bits of the lo word are ignored and so $D0F2 will map t...

That looks very neat indeed. Are you going to add some details about it to your webpage?

Yes - 2ksa was/is for the Kim-1, and is still out there. My initial plan for a Replica 1 assembler was to port it, but I ended up wanting to change so much that it made better sense to write something new - hence Krusader.

Franz sometimes posts here, but is more active in the applefritter Apple 1 forum http://www.applefritter.com/forum/80. I suggest you try there.

The latest code is always available to download from the Krusader website, including a woz monitor format hex version for burning with the simple EEPROM burner.

Yeah - Basic is just awful for structure. To do the conversion that made it able to run so high I didn't need to work out the algorithm in full detail, but it seems to me it is pretty much just doing what you would do if you were calculating each successive factorial from the last manually - i.e. mu...

I use this: #!/bin/sh od -t x1 -A x "$1.bin" | tr a-z A-Z | awk '{ print substr($1,3,4) ":" substr($0, 7) }' > "$1.hex" It's not perfect, but gets it just about right. The output sometimes requires a bit of editing because of duplicate line out...

If you are able to reprogram the chip, I suggest you update to Krusader 1.3 so you can send commands to the Woz monitor directly from the Krusader shell and the mini-monitor.

Yep - that's all fine. The only problem is those last two bytes. I expect when Vince made the ROMs he forgot that although Krusader lives in $F000 to $FEFF, the minimonitor needs the BRK/IRQ vector at $FFFE.

I fear this error could be in quite a few ROMs... :-(

When the BRK instruction is executed, the computer calls a routine at the address specified at $FFFE. That should point to $FE17 (or whereever the mini-monitor code resides in your version of the ROM). Pointing to $0100 is a problem because not only does the mini-monitor not live there, it is also p...
