Thank you in your interest in IBM ThinkPads. I hate to disappoint a customer but I am afraid that in this case the answer is no, due to technical reasons. The showstopper is the BIOS. Each type of LCD panel (TFT color, DSTN color, STN mono) requires the LCD controller part of the video chip to be programmed in a specific manner. Since the 755 has only TFT model and DSTN color model, the 755 BIOS does not support a STN mono panel. The 360 BIOS will not work on a 755 because of various hardware differences, including but not limited to the CPU clock rate (33 vs 25/50/75) and audio (option vs integrated). You may want to note, however, that to the best of my knowledge the ThinkPad 750 series has not been withdrawn yet. Supply of the color models may be constrained in some countries, but the 750 monochrome model should still be available, while supplies last. Thank you again in your interest in our products, and my apologies for the delay in responding.

Perhaps you two can help with some definitive answers. Please reply to the following addresses: antti.kilpinen@abo.fi (The person that asked the question) ychou@uxa.cso.uiuc.edu (The person in charge of the TP750 FAQ) jokim@jarthur.cs.hmc.edu (Me, out of curiousity) Thanks! ---------------------------------------------------------------------------- I need a TP with math-co and a mono screen. Since Tp750-mono is discontinued IBM requires it's customers be more innovative. Actually I want both a 755-mono and a 360Cs (two separate units). Can I (i.e. IBM service) switch the displays of a 360-mono and a 755Cs?. I think the wideo drivers are identical for both color and mono models- how about between 360 and 755 series?. As aresult I would get a 360Cs and a 755-mono. Is anyone on the net familiar with the low level hardware of the TPs?. First, I wan't to know if this is technically possible. Second, I must find someone to do the work so that warranty is not affected) My option is to buy a 360Cs and a 360-mono(instead of the 755-mono) and must suffice w/o math-co. Besides, IBM will loose the price difference of the combinations. Antti Kilpinen, Ph.D (Chem.Eng.)
