Yes, at first only one floppy working, or a: and b: the same image, but then I realised reading the HXC istructions that when using twisted cable from PC floppys a: and b: are selected in the two midle jumpers(J3)...

Now I have:

Of course, you can see it on the screen in the fist picture i've send.

Here is what reads on both screens once the system hangs:

The card is formated with Windows fat32. I don't know if it is important. The HXC emulator doesn't have that option, does it?

Probably some file system error on the card before reformating? (Don't ejected from PC after write?)
I will try to add more verifications.

Anyway what you think about the manager? Any suggestions?

It is will coming built in disk directory and program loading.
Thinking about search function for find specified game.

It works great, but....... at exit, whether F1 or STOP pulsed, the floppy emulator "forget" the previous settings or the made ​​with your manager, and I must reselect the images... Any clue?

I've been looking and can't find any more fault in my mounting.


On the other side it would be great if the manager could allow to launch programs directly from the SD card...
(Edit: I forgot to read the last sentence.)

Or if you do a resident handler for the Floppy simulator to function as a slow HD from a partition on the SD...32Gigas are so much free space...




you've achieved things more difficult

Another bug, not very important and easy to implement: your manager lets the user to assign any file as an image, without even looking if it terminates in ".HFE". Search for a valid image could be very slow, I think. May be scanning the header.

Checking header at selection is on my to-do list :oops:

You have a free ROM socket for the ROM version. It will be more comfortable :)
Do you have an EPROM or Flash ROM programmer?

But something resets the floppy emulator when exiting from direct access(your manager). It`s only to me? The emulator config can be wrong? Tomorrow I will show you the actual settings, just only for reasuring.

Burning EPROMS is something always has intetested me, but seems complicate, doesn`t it?

What you call as reset? "Reading FAT", etc? It is a normal.

No, it is a very simple, especially with the modern programmers (the sw know all parameters more than 1000 IC types).
Only complication the erase: need a UV lamp to do it. I have a germicidal tube which are looking a neon tube. I used a normal neon sockets and ignition switch for build EPROM eraser, putted all in a home made closed box (UV light dangerous for the eye!).

Todays FLASH ROM ICs (29xxx and 49xxx series) and a older EEPROMs (28xxx series) are electronically erasable, more comfortable than the old EPROMs (27xxx series)!
The FLASH ROMs use only single 5V supply for the erase/programming, then it is can be used in the Enterprise system!
I already do it :-)
For the MX/AMD 29F0xx series I wrote programming routine.

If soldering few wires not a problem for you then adding FLASH ROM chip to your card are the easy way to test ROM programs.

Let's see if I can explain the problem:



At the exact moment I press F1 or STOP the HXC emits a long beep and its screen asks me again for a disk image "Choose a file". It is for that I call it a resetting.



Neither the image selection for a: nor b: are preserved, so at the moment your HXC Manager doesn't help me much...

Edit: your manager remembers every time it runs the last selection made inside it, not the previous made by me manually with the HXC Screen Buttons. I don't know if it is another bug or a consequence, but running your manager it should read first what the current images are and then present them in the bottom of the screen before let me do a selection.


"Reading FAT"?  Where is it supposed to appear? I have not seen that...




------------------------------------------



I like what you say about burn and erase ROMs directly from the EP. Also I have an unused connector on the expansion card(you planed it for IDE). Looks like those movies in which a robot repairs itself...

 I'll be able so to upgrade any rom which becomes outdate. I understand replacing the actual chips 27X (ultraviolet erasing) with modern 28X, 29X or 49X. They are all pin compatible, really?



Can you send me the schematics?

Can you save your SDCARD to .VHD file? For example with WinImage or other disk imaging software.

---------
Yes, all type of ROM chips have a very similar pinout, only few pins difference. I will start new topic with the details.

Not necessary. I´ve found the error in the saved configs:

I checked the "Disable diskdrive selector" and all begun to work as desired. As a "side effect" HXC now loads the last installed image disk at power-on and your HXC Manager shows right the previous state of selection.

This HXC is a little but very complex thing...

This is the normal operation, image selection stored in the HxC CFG file.
