Thinkpad 755cx & Mwave

[Guest]

Archived from groups: comp.sys.laptops (More info?)

Hello,

I've been working on/with PC's for many years (since '84), but never messed
with Laptops/Notebooks very much, so all this PCMCIA, PC Card, etc. laptop
stuff is new to me.

I picked up an old IBM Thinkpad 755CX this past winter just to tinker around
with.

Would someone help me identify the model of this old IBM Thinkpad 755cx.
It's a Pentium-75 w/ 540mb HD and 24mb of RAM running DOS 6.22 & Win 3.11.
It's got a Floppy Drive, but no CD Drive. I'm trying to find out more
about the soundcard(?). I noticed that the Users Guide that I downloaded
from IBM's website shows a modem/sound card with 3 jacks (Headphones, Mic
and Modem)... this one only has 1 jack with a music note. What is it?

I've tried everything I can think of... Fresh install of DOS & Windows,
downloaded and installed all the drivers from IBM's website
(http/www-307.ibm.com/pc/support/site.wss/document.do?lndocid=DSHY-3PLMY2)
, but still don't have any sound. Anytime I try to access anything
sound-related, I get an error message saying that the Mwave Sound System
Mixer is not currently installed. I've tried re-installing it, but it
doesn't fix the problem. The instructions said to install the Midi Samples
before installing Mwave, but I got an error telling me that Mwave hadn't
been installed -- so I installed Mwave and then re-installed the Midi
Samples.

One more question... are these Type I or Type II PCMCIA slots??? All of
the website with TP 755cx specs say Type I/II, but one IBM dealer tells me
it's only Type I, while another IBM dealer tells me it's Type II.

Thanks!

Assuming you've reloaded Windows 3.1 (since you specifically said DOS
also) -

I used the drivers from here for win 3.1 -
http/www-307.ibm.com/pc/support/site.wss/document.do?lndocid=GSMH-395EQ2

And then Audio should work - I have one here - just an old machine to play
with. I've installed Windows 95 on a 5 GB hard disk (bent pins 1 and 2 over
so the 755CX will recognize it) - works fine and the audio also works.

For the Modem - I want to remember that this needs to be set up to make some
of the other sound work, but won't be sure on this one.

For the PC Card Slots - Type II - NOT cardbus.

My problem is that the serial port tests bad - and that requires a new
motherboard (not worth it for me)

Hope this helps.

I had (still have, but no longer use) a 755CX. Mine had a 800x600 res
display which I don't think was common to all of them, but I don't
remember. It originally came with a dual boot configuration which they
called Selectasystem (I think). This had DOS/Win 3.11 as one choice and
OS/2 Warp v3 with WIN-OS/2, (meaning it would run Windows 3.1 and its
applications from OS/2, as the other choice. I eventually replaced all
this with Windows 95 and then Windows 98. I recall this to be the best
way this computer ran for me until I replaced it with something newer
and faster.

You must install the Mwave modem in its entirety for the sound system to
work as it should, but I suggest you try doing this with the Windows 98
files etc. if this OS is available to you. I know it had the fewest
problems on my 755CX.

I haven't looked at it for a while but mine still worked the last time I
tried it!

The mwave board may only have been present in the 800x600 version of
the 755cx. There was a 640x480 model that had less stuff in it. When
present and with the mwave software installed, the mwave simulated a
soundblaster and also a 14.4kbps modem. I don't remember if it did
28.8 kbps as well. The software was downloadable from the ibm web
site and somebody had concocted some way to run it under linux, but I
never got it to work on mine.
