Recommendations for an Eprom Emulator |
|
|
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?

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. 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..

EPROM emulators are hardware. They are RAM with some logic, pretending
to be an actual EPROM. You download the data into them through another
port (such as USB), which is where his Win2K/XP comes in. The target
system reads the data as if it was connected to an EPROM, which is
where the size and access time specs come in.
Here's one from a Taiwan-based company and sold by a UK-based company:
http://www.gwmicros.com/public_html/pages/products/iproducts/EPROM_Emulators/Leap_ROM_Emulator/EPROM_Emulator_Leap_WICE-M4.htm
(I hope the Denbighshire company knows more about supporting such
products than they know about using apostrophes with possessive
pronouns).

What is the target MCU?
You make find and old second hand ICE for it rather than an EPROM

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.

It's been quite a while since I used this type of device, but I was
very happy with Tech Tools, www.tech-tools.com. They had inexpensive
devices that ran off a parallel port under MS-DOS, Windows 3.1, and
Windows 95 (yeah, a long time!).
They also provided excellent technical support. I damaged one of
their emulators and their policy at the time was to turn it around
within a very short time, 24 or 48 hours if I remember correctly. And
if you managed to break one through your own fault, if they couldn't
economically repair it, they'd sell you a new one for half the price.
Of course I can't say if their policies are the same today, or whether
they have USB, but I'd recommend you check their web site to see if
they fit your needs.

Thanks Chris,
Various CPUs. I like to "repurpose" older electronics I find at my local
surplus shop. I look for boards ideally with socketed EPROMs so I can easily
extract the code and make changes. This started a long time ago with a
Defender video game. I have recently worked with the 6809, 6502, Z80, 8085,
68HC11, HPC46003. The clock rates on these older processors are slow 1-20MHz
so the demands on the EPROM are not so great.

I looked into what one of my favourite Forth Vendor's was selling these days
and found that they currently sell the PROME-ICE device. This is a more

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. |

I agree with you Go for am Eprom emulator... You may find old ICE for
some one or two of those but an Eprom Emulator is the best compromise
for that lot.
Have fun.
BTW a lot of the older eprom programmers (Dataman s4 for example) also
had an emulation mode.

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.

Try www.alptex.com. They make a very quick Ethernet based emulator with
3/5V support and plenty of memory. I use it here almost daily.

While that is true, they only do one EPROM emulation at a time. If you need
to stack emulators for multi-prom devices then it becomes a somewhat more
expensive solution (eg 16 bit systems). I have the S3 as well as the
stackable system run from the parallel port.

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.
As it stands, it is for the OP to filter and evaluate the various
suggestions that have already been made.
