Re: ThinkPad 600 PCMCIA Problems (Win 95)

It's been a long time since I messed with PCMCIA drivers, but as I recall the DOS drivers and programs, or "real mode" was different than the Win95 driver and programs. There are/were warnings in the IBM ThinkPad text documents about trying to use both or one vs. the other. It also had configuration...

Re: 5-1/4" Floppy drive on the 770

Uh... no. No there weren't. There was a half length expansion slot on the original dock from 1992 that you could add a microchannel FDD controller card and attach an external 5.25" but I never saw anyone implement it. Here's a link to the adapter manual: http://www.minuszerodegrees.net/oa/OA%20-%20I...

Re: HDD caddy for the 360

If you look in the "Personal Systems Reference" it states that the IDE disks in caddies for the 755 series will work in the 360 and 750 family. Those went up to 1.2GB according to the documentation. I can verify up to the 1.2GB working (with the BIOS upgrades). I thought I read somewhere that the la...

Re: Contrast/brightness controls on active matrix LCDs?

I'd have to look, but I recall the User's Guide for the 750C stating it was one way for TFT and another for Monochrome, etc. I noticed later production display units didn't seem to follow that convention.

Re: HDD caddy for the 360

The answer is mixed. The ThinkPad BIOS has to know the drive geometry or it will not be recognized correctly. Later BIOS versions will recognize a blank drive up to and including 1.2GB (so the later drives in a caddy from the 755 would be useable in the 360 or 750). Without the BIOS update, you coul...

Sure. There are links from here somewhere to the files at Lenovo, as well as 5-10 sites that made copies of IBM's PC FTP support directories before they went offline.

Re: Hello! I bought a Thinkpad 240 from the Car Boot

I think it may be hard coded in the BIOS as to which CD-ROM it can boot from (i.e. IBM), but it should boot from floppy and read from any PCMCIA CD-ROM

Re: AIX IBM RISC System 6000 N40 Type: 7007

From the picture it looks like it's running AIX version 3 something. I'm sorry I missed the auction. I did Y2K migrations from that version.
If anything went wrong with that unit, I would have no idea where parts or install media could be located to fix it.

There are a couple of issues in addition to dead cells that have made refurbishing the battery impractical.

Yup. Lenovo does the same. You have sub models available for quick shipping or custom orders that end with CTO.

The 701's were all available from March 1995 except for the 7SU/7TU available in September 1995
It was for different CPU/HDD/Display type combinations.

I've only seen marketing flyers of those models. The price would depend upon the collector. If they have everything including original software, I'd think $200 would be reasonable, but that is just me.
