They're so simple and that's why I like vintage technology so much. None of this planned obsolescence constant internet connection garbage they're pushing out these days. At some point I'm actually going to get moving on rebuilding the battery pack of that 5140 and I hope to have my own Green...

the good thing about NiCd/NiMH batteries is that most of them are dumb batteries. For example in my 5140, the battery is so dumb that it just has two wires - the terminals

Looking at the data sheet, the bq2010 doesn't seem to have an overdischarge lock out so theoretically you should be able to replace the cells and it should just work. keep in mind I'm no battery expert

Sorry, my memory failed me. I just looked to make sure and it's only a KL320. I'd definitely appreciate it if you could find one of those Xebec drives though

Nice collection you have there. I've been trying to find one of those Xebec-relabeled drives for a while. Have you gotten your hands on a KL330 yet? I ask because I have one (in Kalok factory not working condition :ROFLMAO: )

I have a Vectra VL in storage so if these are still available by the time I get to look at it, I'll post back whether any of yours are a match

Yep, that's correct

Sounds like quite a rough time. Hope all is okay now and take as long as you need. the weather pattern should have gone towards the desert states, they need it more than us

Wouldn't mind at all. Do you possibly have any that don't show external signs of leakage?

How much would one of the laptops plus a battery be

Oh yeah, I wasn't expecting to ever find a new or working one but was more hoping/expecting to find a dead one to rebuild.

Quick question - does anyone have any leads on a potential source of main batteries for these? I'm interested in buying one but would hope to find a battery, even one I would have to rebuild

Just to clarify, I mean the two images on ibm-pc.org - I didn't catch my mistake before the post edit period passed.

Those two images appear to be the same as the one I uploaded. Yep, they're labelled and I'm listing them below. B33 and F34 B42 and F34 B58 and F73 B58 and F74 B61 and F74 B62 and F74 I have one more but it's in a closed computer.

I did a little more testing earlier today. Swapping the 2764s from one drive to another allowed SpeedStor's write tests to function but attempting a low level format resulted in a "Bad command to disk BIOS" message (and it also made the drive ID as 10MB but manually entering the parameters into...

And these are the BIOS images

Just an update, I got that drive to work long enough to verify that I wasn't imagining that, and I wasn't. This photo is SpeedStor performing a LLF on that drive and to follow shortly will be the data from the 2764 and 27128 EPROMs

That's what I was using and that's the program that let me format that one Hardcard. It's a great program. I can get photos and BIOS dumps up here sometime within the next week. I will admit, some of the boards might no longer be identifiable to me on account of the actual hard drive assembly...

I've been tinkering with Plus Hardcards (most of them are dead for various reasons) and I have a few that will read some tracks but not all. That got me thinking that it was MFM style magnetic field degradation (the style that's fixed with a low level format). Now most of the cards I have...

Are you looking for the ones with the ports at the bottom of the front cover and the oval power button?
