Unfortunately, I cannot get the PCMCIA to work on this thing and I might have the incorrect drivers set for it.

Yep - as a former owner of the T2135/50/55 series, I can totally attest that they are good, solid machines for the 486 era.

I think Toshiba laptops came with Phoenix CardManager software. Did you try it?

Found the PCMCIA drivers from the T1950CT archive and got it installed.

I managed to pick up a Thinkpad 755CD with floppy drive and original manual at a good price ($60). Upon boot up it displays a floppy disk icon and indicates the F1 key to be pressed - nothing happens of course as the hard drive has been pulled! It’s also missing its original AC power adapter.

Apart from a new HDD and power adapter, is there anything else apart from a leaky CMOS battery I should look out for with this unit? Cosmetics look pretty decent for its age but the battery of course doesn’t hold a charge.

Can one still find new / third party power adapters and batteries for the 755CD?

This will be the oldest lap-computer in my entire collection if I can get it working.

I used one as my main machine in the mid 2000's. I had an iGo generic power supply for it at the time I bought at Radio Shack for like, $80. There might be some decent Chinese replacements or used OEM units. You kind of have to hunt for them though because ThinkPad stuff tends to go for a bit these days, usually.

If you want a battery I'd look for that Lithium Ion version, they made these with NiMH and Lithium Ion (I put a new Lithium Ion battery in mine when I got it, 2 hours time). - Just for a cross reference for part numbers - http://www.elec-shopping.com/laptop-batteries … nkPad%20755.htm - $62 at that site, might find better on e-bay or elsewhere.

As for what I use now...currently I'm trying to tweak and tune my NEC Versa M/75 into something that did not exist - the NEC Versa M/75HCP - a High Resolution Color (800x600) with Touch/Pen. And I just ordered a Panasonic Sound/SCSI card for it to give me at least OPL sound for the DOS Games that use it. It'll be really cool to use this thing for pixel art with a pen, as well as play old DOS games on the go since the battery works, and I've also brought one of the 30 year old NEC ones back to life (and the runtime keeps getting longer the more I use it). I might also put new cells in the other two I have if they don't keep growing in runtime as well (complete drain then re-charge). A touch-screen convertible laptop with WiFi, OPL, WSS, and SB Support w/ a SCSI feature, and a dock - were basically looking at the Microsoft Surface of 1994 here. I use Cisco Aironet WiFi cards tethered to my phone for internet when on the go, and it uses so little of my data plan I can use it like that a lot in a month.

From what I understand from the Thinkpad forums, the Li-on battery can only be used with the Pentium 75 version of the 755CD - without some tweaking that is beyond me.

I can’t remember the model but my dad had something from the 1994-1996 Thinkpad line when I was a teenager growing up in Hong Kong and it was one of the defining moments of my computing obsession.

I’m hoping to find a nearby Thinkpad maestro who might be willing to have a tinker and restore the unit for me. It’s a bit out of my comfort zone but I’d love to have a working copy.

Your project sounds like a fun one, I lean towards replicating the original experience as closely as possible and in your NEC case - why not if you have access to the parts!

Hmmm…take a look at the Thinkpad release history on:
https://www.thinkwiki.org/wiki/ThinkPad_History
And see if any of the models seem familiar. The hardware maintenance/service manuals for most are still out there and easily obtainable.

Chances are - if you can read Chinese (simplified or Traditional) there are gurus north of the border with a thing for those oldies posting off sites like 51nb.com, and it’s just a question of whether you trust them or not. The issue here is that for those ~25 year old ThinkPads even the NOS spare parts are probably long gone and dead. That being said, you can often find old laptops for cheap from Japan, often machines that are very well taken care of- you just have to use a service like Buyee to deal with something like Yahoo auctions.

Just to update this thread, the Thinkpad 755CD I thought I had bought turned out to be a 755CX with Pentium 75. Apart from the lack of CD-ROM, I’m pretty happy with it. Love the chunky design, form factor, keyboard hinge and once I get my CF card reader PCMCIA I should be able to do much more with it. If that fails, I have my eye on a copy of the original external IBM CD-ROM.

I have a Compaq LTE 5200 with a cracked display lid (transit bash) which has a somehow fubared the display - a spare 10.4” LCD sits awaiting surgery.

I was hoping the 755 would be a DX to differentiate between the LTE 5200 but it turned out they’re both Pentium - albeit the LTE has the faster 120mhz Pentium.

One of them has to go but I’m not sure which one - perhaps the one I can find a dock for?

This Compaq series is not very good for Dos gaming, cause cheap graphics adapter Cirrus Logic does not allow scaling to full screen. You will get games in small window with large black border around.

755CX is a nice laptop as well. From my experience CD-ROM is not a very useful device, unless you already have a big games collection on CDs. Othervwise, if you use CDs occasionally, you can mount an ISO from PCMCIA-CF in DOS or Windows. CFs up to 2 Gig should work fine on it. And you can even boot form it (sometimes requires some black magic to partition the CF).
The only thing that people usually complain about is the MWAVE sound card, FM emulation, in particular. In case of 755CD (which I have BTW 😁 ) it's compensated by built in MIDI port. I don't remenber, does CX have one?

Yeah, I was thinking of making do with it. It’s in good working and cosmetic shape and the main & bios batteries even hold charges so I can’t really ask for more given its age.

Recently acquired a Toshiba Satellite Pro 400CDT. It'll get repairs and cleaning done before I start to use it. Could use a CD-ROM drive, external floppy enclosure, and a hard drive (got a drive to test).

Nice, I had my eye on one of these for a while but ended up going for an M17x R2 - something about a big, chonky bastard of an Alienware - and dual GPU to boot - gets me going at times 😉

Specs are:

CPU: i7-820
RAM: 12GB
GPU: Dual ATI Mobility 5870 1GB Crossfire
SSD: 500GB Seagate Momentus XT

This thing weighs over 12lb without its power adapter though so it's not exactly portable!
