Nothing to test this on, so I am coding blind :shock: However try the attached. This version of NFX.COM has (in theory) two differences from Andy's one: On start-up it reads an optional configuration file NFX.CFG containing one to four lines: IP address - Defaults to 192.168.1.123 if no configuratio...

Thanks for the link to the W5100 data. That is a lot to emulate, a 32K address space!

Andy's source may include sufficient information on the hardware interface, I will have to take a look.

Network clients are generally slightly easier to write. A client is typically only dealing with one transfer at a time and so can often be single threaded, whereas a server has to support multiple connections so almost has to be multi-threaded. However, given that Andy has already written the HTTP s...

I thought that this discussion needed a more meaningful title :) Except that changing the subject line does not change the title of the thread :( It might have been better to have started a new one. There are many possible protocols that can be used to transfer files over a network: HTTP - Hypertext...

I suppose that most users with a 3.5 inch SDX are aware of the bug in the SDX ROM, which overlaps the allocation vectors and the directory checksum vectors for the drives. This can cause failures when attempting to save files. The bug can be demonstrated in MEMU. Start MEMU with the following comman...

The system variables give the address of the end of the program also the end of variables. TapeView uses that to know how long the following BASIC data block should be. However it was assuming that the start was always at 0x4000, hence over-estimating the size of the block for programs saved from an...

And a screenshot of "LUNAR1" on MEMU:

It took a revision to TapeView for programs saved from an MTX500 (starting at 0x8000) rather than MTX512 (starting at 0x4000). The code now checks LSTPG so should work for either case. A few other minor issues also tidied. Revised code attached. The audio files show some bad fades in places, however...

No documentation other than the notes in this thread. For some scan modes, the "Up Cross" and "Down Cross" values are shown as horizontal lines on the plot, and are thresholds for change from Low to High or High to Low. For the various High-Low modes they are the minimum level ch...

Progress so far (UPDATED): Side 1: Contains four programs "LOGRAPH1", "3DORBIT1", "3D-ORBITS" and "3DORBITS". Scan mode = High - Low, Up Cross = 0.1, Down Cross = -0.1 produces an MTX file which will load "LOGRAPH" into MEMU. The above settings do no...
