fit MY needs. I've finished to build an Programmer for CY7C291 and Am27C291
Chips yesterday and it has a simple AtMega644P CPU on it.
This way I have enough RAM to buffer the ROM contents + some extra for the
Program on the device.
Could have build it with an FTDI in it, but what for?
I can connect that device to old Computers I'm using, starting with some
CP/M gear (mostly Robotron), an Zilog S8000 compatible System (EAW P8000)
with some Zeus Unix Clone on it (WEGA) and even an PDP11 or a VAX.
Some Terminal Emulator is sufficient to do useful work on it.
Software is mostly the same (excluding the Program algorithms itself) to an
previously build 2708 Programmer that I've build since almost none of the
actual Programmers support them anymore. Next one is for 1702As.
I don't need shiny gadgets with USB, most modern gear has JTAG/Flash anyway..
I have an Conitec GALEP3 to, it has a parallel port. Modern programmers
Okay (although this could have been resolved with
a simple lookup on
USB protocol).
This implies that the USB protocol is simple and that looking it up is
simple. Ever tried googling "USB" and trying to get some useful
results? Skimming the wikipedia page didn't lead to enlightenment
either.
The third term should be obvious.
Should be, but since people were being euphamistic, it wasn't clear
exactly what they meant.
-- from this companies can handle 3,3V Devices, have USB
and a Linux running
in them... who needs that?
