NEW: SHARP PC-1600 USB-Stick Interface

Message par spellbound »

Hi folks,
I'm happy to make an announcement for a new SHARP PC-1600 hardware/software!
The hardware in fact is not new - it's my Modular Extension Platform (MEP).
But I've created a new embedded software application for it:

A fully integrated USB-Stick interface that is hooked up as a standard PC-1600 file device named "S3:"

Image

That was some intense research including disassembled OS-ROM analysis during this year in order to find out how to implement a proper PC-1600 peripheral file device. But finally it's working!

With this thing you can have a seamlessly integrated, structured mass storage for your PC-1600, that contains all programs, data and videos you will ever find or create 8) What do you think?

If you are interested in more details, here is the full manual:
SHARP PC-1600 Modular Extension Platform r2 - Manual
As always, feedback is welcome :wink:

The manual also contains the description of my USB-keyboard adaptor application, that some of you already own.

I will offer a new batch of the MEP (preconfigured with an application of your choice) in the trading section of the forum as soon as possible. But here's the downer: The current situation at the integrated circuit market is a real pain. Not even the wide spread microcontroller ATmega328P that I'm using is available from the typical dealers. And the other thing is, that the prices are going up due to shipping costs from China, so I'm currently not able to calculate a price for the module in advance.

Lets see how it develops

[EDIT] I created a waiting list for this module:

Meilleures salutations

Hi ,

I have the USB Keyboard interface.
So is it possible to reprogramm it for using USB stick instead ?
Or it's not compatible ?

Ideally with the capability to swicht to KB or USB stick app time to time.

Thanks

Hi,
Short answer:
yes, it should be possible to change the application, but you couldn't go back.
Long answer:
I had to make some minor modifications to the USB-frontend hardware in order to work as a flash drive interface. So there is a new hardware version, that can handle both (incorporating a switch, that the first version that you own does not have).
So the rev2 hardware version can handle both applications, the rev1 hardware version must be modified a little bit.

To switch between the two applications by yourself, you would need an EEPROM burner, an ATmel microcontroller dev board like the dragon and an open ended FTDI-USB cable.

So if you own a MEP rev1 with the keyboard app installed, but want the USB-stick app instead, I can offer you a service. But you couldn't switch back in that case.

If you are interested in the service you can write me a PM

Hi,
Recieved saturday my "old" USB keyboard module serviced by Tom and moved as an USB stick module.

It's work great (after some little time to understand it). No more hassle with software conversion (like bas2wav). No more need RS232 module and terminal.

I was able to use directly all basic or binary from https://www.sharp-pc-1600.de/eng_download_rs232.html. No need to format Usb stick (except if not by default as fat32 or exfat)... I use a 8 GB corsair voyager stick.

It's a pleasure to use directories...

The only thing I'm still currently unable to use is the file browser disckwork.
The soft found on the above site can permit to create a diskwork.bin file on S2. But when launched nothing happen...

Hi,
thanks for the feedback! Thats what counts for me ;-)
I‘m not sure if the DW version you‘ve cited is intact.
I just sent you a binaray version via eMail - including usage with the MEP/USB-stick app.
Give it a try
Cheers
Tom

Thanks discwork work good now.

Sadly seems not take care of directory. I suppose it's need to be updated for that, as directory management was not possible before.

Exactly. Neither DiskWorks nor any other PC-1600 program or the operating system itself has a notion of the directory concept.
But of course you can select a directory on your USB-stick with the CDIR command *before* you start DiskWorks.
Then DW will ‚think‘ that this is the whole content of Y.

Yes and a reserve key for the bload"s2:dw.bin" make all the thing a lot better.
