The sound comes from something caled IBM "Soundwave" which is a combined modem and sound card with some midi capabilities and Sound Blaster 1.5 support which to my ears sounds very good

Unless it's something different from the desktop version, it's called MWave. And it's one of the most notoriously frustrating pieces of crap ever made, both as a modem and as a sound card... IIRC there was even a class-action lawsuit over it at one point. But... if it works for you, great.

Let us know how that IBM sound works. If it works. 😀

Also I'm wondering how the LCD is. Is it yellowing? Also, for that price it should be an active matrix screen. Fortunately.

Yes, I stand corrected..it's MWave 😀

What were the issues with MWave back then?

The sound works, have tested it in pure DOS with some games
But I haven't figured out how to activate the midi stuff yet....when running the sound config in DOS (FASTCFG.EXE) it just says it's disabled and there's no way to activate it.

Nope, no visible yellowing 😀

In the manual the say it's a "TFT" screen...I thought these screens were called "LCD" back then?

TFT (active matrix) LCD screens were then marketed heavily because older LCD screens used the DSTN (passive matrix) technology. TFT displays are superior to DSTN ones as DSTN can look washed out, a little murky and generally have bad response times (resulting in ghosting).

let's put some emphasis on that. 😁

dual scan/passive matrix = bad response time
more properly referred to as blur mush sludge. The high viscosity LCD hehe.

d**n thats an old laptop i've playing around with the Toshiba 2800 and 2805 satellite series, i almost know them inside and out like the back of my hand. hhmm i wonder if i us AS5 how well would it over clock or how badly will it over clock, hhhhmmm.

Haven't found any info on how much RAM it takes

or flip it over get the model number and google it with the words specs

Got a the dock for this laptop with another broken Thinkpad 755CX

What's interesting about this dock is that it has an ISA slot 😀

Haven't decided what to put there yet but if I can disable the crappy mwave soundchip on the Thinkpad I'll use a Sound Blaster 16 in the dock

I want a PowerPC Thinkpad. 😁

PowerPC? but what you want to run on that? must be horrible for retro gaming but great if you're a linux-nerd or something 😉

Woah an ISA slot now thats cool and interesting that opens up some possibilities.
