Re: [ts-7000] SBC without the peripherals

["Don W. Carr" <>]

I can't answer all of your MIDI questions, but, go to the 7200 page,
click on the tab "Pricing & Options", and you will find qty 1 is
$149.00. 4x4 keypad is $28, lcd (2x24) is $40.

All of your Turbo C code should port over just fine, if you isolated
out the calls for port communications. You should only need to re-write
the hardware specific parts. Yes, gcc with all warnings enabled will
probably tell you about some things you should not have been doing. 

Don't worry about buying the extra serial ports and usb. It really
costs very little since it is built into the system on a chip, you just
pay for the connectors. And, for the USB port, you can connect an
802.11 wireless adaptor which might be interesting for future
applications. Also, with the serial ports, it will be easy to add a
remote screen / keypad (say 50 ft). You can now buy dirt cheap lcd
display with keypad interface and serial port (microcontrollers are
getting cheap). I bought the one below, which is a lot bigger than you
want (4x40), and it even supports up 2 55 keys (5x11) though I used a
4x4. ($165.00 with 4x4 keypad)

If you wanted 640x480 vga with usb keyboard, check out the TS-7300.

The TS-7200 supports compact flash, so you should have all the
non-volitile storeage you want. You might think about the TS-7260 with
SD card option, or the TS-7300 with two SD cards standard.

Well, I can't answer your other questions. Good luck.

I've talked previously about my project to develop a MIDI appliance.

I hope you all don't mind a few more questions about my decision making.

The big question for me is "what is the cheapest and most flexible
design architecture to use given the processing requirements?"

Requirements:
32 MIDI ports (16 in, 16 out)
20x2 LCD
4x4 keypad
10/100 Ethernet with IP stack.
Enough processor and RAM to allow simultaneous reception and
transmission on all 32 MIDI ports, and send, receive on Ethernet.
Enough non-volatile storage to store user settings and OS/application.

Now I could do all of this with my old 1992 developed Zilog Z80 SBC
computer except for the Ethernet and IP stack. Though even if I had
Ethernet for the Z80 I'd still like to keep up with the modern world!
Still, I have a huge amount of MIDI assembler code ready for the task.

Unfortunately, the TS-7xxx series has all of these extras that I don't
need like USB, 2 Com ports etc. Is there a TS board that just has the
flash, the LCD interface, a keypad interface, the processor, the RAM
and the PC-104 interface?

The web site says $119 for qty 100 or more. Just how much am I going
to pay for the TS-7200 as a single unit?

On a completely different note, I have a huge amount of MIDI
application code written in Turbo C (remember that?). How hard do you
think it is going to be for me to port/rewrite device drivers into
Linux? Should I just accept starting from scratch or are all of those
old DOS interrupt calls and hardware calls still somewhat valid in Linux?

Once again, thanks for your help and any input is very much appreciated.
