OK - converted these screenshots to a binary image and the attached is what we get.

The ROM entry point is $18E0.

It looks like it''s a fair old size - possibly 16Kbytes from $100x through to $2FFF.

If you have the screenshot time - I am more than willing to punch in the data to see what we get!

The writes to $4xxx would appear to be mirroring $0xxxx - hopefully.

Sorry mate I am unsure about what you need.

Do you want me to "dump" 16KBytes from $1000 to $2fff with my BASIC program?

Please instruct me asap.

Sorry I have to be "pushy" but I need to repack my Salora Manager stuff ASAP (in a couple of days).

I want to make sure that I can help you as much as possible before that date.

PS What do you mean by screenshot time?

OK - today no hangover! - good start :)

OK, yes I would need a dump of the memory space from $1000 to $3000, using the method you used before.

By screenshot time - I mean how long it takes to capture each screen full of data - so if it takes 1 minute - the entire process should take about 16-20 minutes.

I am not completely sure that this will be the final range - and we could be lucky in that it actually starts at $1800 - but best to be safe!

Thanks for putting the time in - it's appreciated!

I modified the program a little bit to dump 128 bytes at a time (256 bytes won't fit the screen unfortunately).
Screenshot time is about 15 seconds to output data, shoot the photo and type a key to continue.
Most of the time was spent in resizing, cutting and sharpening the images and saving them to numbered files. Total time approx 35 minutes.
Unfortunately I have very limited internet data these days so I have to reduce the size prior to uploading the pics to my server.
64 screenshots total, dumped area is $1000 to $3000 as requested. :)
I am uploading the pics into my server. Please download the file from:

* PLEASE CONFIRM ONCE YOU DOWNLOAD IT *

PS: I can dump more tomorrow if you want, then I will have to repack all my around tuesday.

Out of curiosity, how do you convert my screenshots into hex data?

Initial observations

ROM is mapped at $1100 - $1FFF, and from $2100-$2FFF
DISK I/O appears to be through new ports beginning at $1120

The available commands, as seen in the ROM are:
FORMAT, LOAD, SAVE, RUN, KFN, UNSAVE, PROTECT, UNPROTECT, CLOSE, READ, EXEC, WRITE, OPEN, RENAME, DIR, KFN1, KFN2, MSAVE, MLOAD, MRUN

The ROM image is my first pass - so there may be some typos still in there. My priority was to ensure that it was not obviously calling some non-BIOS space, as we are short on time.

Attached is the binary and crappy C code :)
