Lexicon PCM 80 memory upgrade

I'm trying to upgrade the memory on my PCM 80. I bought the proper SIMM
chip (30 pin, 70 ns, 4MB x 9). I've installed it in the slot. However,
there is a jumper and every way I reconfigure the jumper, the unit either
doesn't recognize the memory or doesn't power up (I get an error message
that says "E7 "). There is also a second chip slot, so maybe I have to
intall the SIMM in pairs.

Any help is appreciated. Please e-mail me privately - wa...@planet-3.com

Thanks -

Walt

Dear Mr. Elvis

You need to fill both SIMM slots and set the jumper so it will "see"
the additional RAM. The E7 error is probably because both slots
are not filled. A quick call to Lexicon will verify that this is the
case and they even have a cool technical support section that will
most likely answer your question.

Wandering into Usenet and asking if the Mac or the PC is better is
sort of like wandering into an Irish bar and asking if Catholics
or Protestants are best. You might learn something about religion
in the process, but not much, and you stand almost certain to be
injured in the crossfire.

you have to fill them both! I received E7 even with two 9-chip Simms
in the unit, two 3-chip Hitachi-Simms of newer date work perfectly.
BTW, two simms of 1 MB give you up to 10 sec stereo-delay, do you need
the 42 sec. possible with 4 MB???

Yeah, somebody was kind enough to e-mail me with the info.

As far as Lexicon goes, when I called them (on Friday, June 4), the tech
support staff was, according to a voicemail message, "away at a group
function". Their web site had zero info.

Much thanks -
