My team has used PROMIce emulators for over 10 years.
While the emulators are well built and reliable, in the past
couple of years the company seems to have contracted or changed
ownership, to where it was difficult to get a salesman on the phone, and
the web site was unreliable.
Unlike virtually every other development tool, PROMIces have never
gotten less expensive, and as near as I can tell, still don't support
USB. The parallel port driver required for use with NT/2000 is
difficult to install correctly, and, for me anyway, caused BSOD
(although the serial link is very reliable, although slow).
Rather than offering 3.3V emulators, these require a level-shifting
adapter, which makes the already fragile cabling to the embedded device
a complete pain.
Your mileage may vary.
It's not one I am using (my old set-up from my Forth vendor is still working
for me from the parallel port). I guess that I should probably consider an
update to an ethernet connected one as legacy style interfaces become rarer
on available PC hardware.

That is the problem the disappearing parallel and serial port. so many
bits of kit used the parallel and serial ports.
I could make all sorts of gizmos with an RS232 interface but I can't
just "knock up" something with USB or ethernet. A great pity.

As the probable Forth vendor for the Leburg EPROM emulator,
which used an ISA card in the PC, let me comment on EPROM
emulators.
These days, EPROMs are mainly a legacy issue. Emulating Flash
is just more expensive because of the variety of pinouts. In
addition, most Flash is surface mounted, and a large number
of CPUs use JTAG for programming external Flash.
If you really want an EPROM/Flash memory emulator with
an Ethernet or USB interface, a good one will be expensive.
Most of our clients still using Leburg emulators keep an
old PC alive to run them.

Hi,
It occurred to me that it might be a good idea to make up some NEW PC's
"for Engineering use".
IE 3.5" and 5.25" floppy drives with 2 parallel and 2 serial ports on
them along with one or two other useful IO and the ability to triple
boot into DOS 6.22/Win3.1/ win98SE and probably Win2K. Thus they could
run all the old programs and talk to all the old peripherals.
Obviously you would need a CD drive as well but I don't think it would
need a particularly lard hard drive. In those days if it came on 4 1.2
MB floppy's it was HUGE!
It might be worth pricing up as a stock item.
What does anyone think?
I do have 2 PC's with 5.25 and 3.5 drives on them "just in case" Also I
ALWAYS have serial and parallel on all the PC's.
It takes a few moments to do an RS232 link to a peripheal... some one
emailed me and said it is not difficult to do USB with an XYZ MCU....
However I don't have one of those and most MCU have an rs232 port or can
do easily. Most PC#s have a terminal program and the RS232 code is easy
to do at either end (no enumeration etc)

Hello,
Its time for an EPROM emulator. I would prefer USB, >1MBit, fast down
load,
Win2k/XP compatible tools, <40nS access time. What's everyone using out
there? Anything to recommned/Avoid?
Bob
What the ? An EPROM emulator ? Now I gotta admit that I've currently dropped
off from what you're trying to achieve. As far as I know, emulators are
pieces of software that emulate specific devices.
No. an Emulator (or an ICE) is hardware
A simulator is software.
From this description, I
understand you want an embedded device which has a software code that can
act as an EPROM emulator, right ?
I don't think any such devices exist, but I'm not absolutely certain..
- Antti Keskinen
An Eprom Emulator is a piece of hardware that was popular in prehistoric
times.... about 5 years or so ago and back. This is when Eproms were in
DIL packages and took 40 minutes to erase.
It was in many ways the JTAG of it's day.
Although I used our real HPC emulator on occasion (until it died), I did
a great deal of my HPC testing and debugging using a row of DIL eeproms
and a UV erasor. Since I only ever need to make minor changes to old
HPC programs these days, I use trial-and-error with that most oxymoronic
of devices - the OTP EPROM.

SST makes flash devices that directly replaces EPROMs. They can be
programmed in an EPROM programmer, but can be electrically erased
before re-programming.

Some one sent me an off list emails saying: "USB is easy use the FT232BM
chip."
As it was one of these numbered aol accounts it is probably from some
one who works for the company that makes them.
The part in question is about 6USD and is a LQFP.....
So as I said: It is much easier to use serial, rather than in this case
use serial and then add an additional QFP part to convert to USB.
If I wanted USB I would use a micro with USB on it.
