'Parallax ClearView Mathias sold off???'

I ordered a Parallax Clearview from DigiKey today at work, and was told
that the module required for 16C74 support was "discontinued". I called
Parallax (after seeing that it was still listed on their web page) and was
told that the Clearview line was sold off (I forget the name of the new
owner) but that Parallax would still be supporting it. I was able to get
the necessary module directly from them, as they had [at least] one left.

BTW - Any comments from users of Clearview? Did I make a mistake buying one?

I used a friend's, and didn't like it at all.  I'm using the IcePic now,
which is
- better constructed (the emulator pod board doesn't fall out - its
internal - easily accessible, though))
- has an easier to use and less buggy PC-Windows program
- has adjustable com port speeds.
- has support for multiple files, and in general works better with C.

You get reasonable dialog when you email them.  I'm not sure if this is the
case with Parallax

I have one and have been very satisfied.  The support (at least by the
distributor in Oz) has been very good.  I haven't used any other
emulators so I can't make a comparison.  I can say that having used
an emulator I wouldn't ever write code without one!  You certainly
didn't make a mistake - they are wonderful devices.

Hiya Chris,

I believe that Tech-Tools bought the Clearview line -- at least they are
selling the Mathias in their latest ad. I just saw this ad in the latest
issue of Circuit Cellar INK.

Hey, if it works for you, your money was well spent. If Digi-Key has a 30-day
money back policy, put it through its paces and make your decision.

Best wishes,

Ken Pergola

I have been using the Mathias for 1 year, mainly ' 74 and of late ' 73 &
CCS C Compiler and it is working great for me!

Jerry Merrill at tech-tools tells me they have scheduled a first release of
their software for Mathias April 1.  (hopefully no joke) They are asking
for feedback at
.....mathiasKILLspamspam.....tech-tools.com for on-going development.

Actually, this will probably be its salvation.  THe new owner is
http://www.tech-tools.com and they're pretty well established.  They are going to
have to do some layout changes, though, because Microchip is changing all
the PGA -ME chips over to PLCC.  I wouldn't be surprised if that's what
prompted Parallax to sell off.

FWIW, I would get the '77-ME part instead of the '74.  The differences are
fixes to the BRGH=1 bug and more RAM.  If you remember that those things
are different (only use BRGH=0 if you're emulating a '73/74, and don't go
into the extra RAM) you should be ok using that part for both.  I have the
'77-ME part now (windowed, too!) so I know it can't be too long....

I get excellent support from Parallax for all their products.

I've been using a RICE-16 from Advanced Transdata for the '74 and '55
and the CCS "C" compliler.  I've experienced some unreliabilities.
The emulator sometimes doesn't really run when started and I halt and
restart and it works.  Also I can't go beyond 10 Mhz with the
RICE-16.  Has anyone seen similar problems with a mathias?  Can you
go above 10 Mhz with Mathias?  What about PICmaster?

Shawn:

I know nothing about the Mathias; maybe Andy Kunz can answer that
part of your question.

The PICMaster will emulate 16C5x devices at up to 20 MHz, and it
(well, the -CE version, anyway) will emulate 17C4x devices at up to
25 MHz.  Emulation of other devices is currently limited to 10 MHz.

Yeah, but what about the reliability?  Any better than RICE-16?

Shawn:

The PIC-Master is supremely reliable; if cost is no object, it's the
best emulator available for the PIC family.

I hope you appreciate this <G>.  I had to clean off a space from my taxes
(fun day today 8-( NOT) to plug it in and see.

It gave clocks up to 20 MHz for a '5x.

For a '62-'74-type-chip (74-ME installed) it topped out at 11.0592.  Same
with a '711-ME installed.

I didn't check the '84 because I'd have to remove the '711 which is what
I'm working with right now - please forgive.

You can always try asking Parallax or Tech-Tools to provide a specific
frequency.  I did at one point and they sent a table to include my
frequency.  Only problem is, they didn't make that part of the release
table, so as soon as I upgraded my PDE, the new speed disappeared.

There are probably physics limitations on what they can give for
frequencies, though.

Glad to hear it!  I haven't personally contacted Parallax, but my friend
who owns it has, and is far from content with their responses, so far as
the feedback didn't result in desired bugfixes.
