Bargain!

I can't help showing off a bargain from that auction site again. This time I found an HP 16500A logic analyser for very few pennies. It didn't have any software with it, but eventually I found that on a site linked from Agilent.

I later found a blogger who had put up details on how to write the software onto diskette, and it went something like;

1) find some 720K 3.5 inch diskettes
2) find a machine that can run DOS and has a diskette drive
3) run the LIFUTIL program
4) format the diskettes to a very strange HP-UX compatible format

5) write the system code to a diskette
6) write the correct code for the options you have on a second diskette
7) enjoy

720k diskettes? Pah! a mere bagatelle. Remember when we used to get boxes of diskettes in perspex holders? I do, and I have a couple of boxes still.

A machine that can run DOS? Well I have an old Toshiba Satellite 110CT, which boots into Windows 98. Close enough. And here it is. Unfortunately the little pigtail cable for the Xircom ethernet PCMCIA is missing. I have two other PCMCIA network adapters, but they are both cardbus and won't fit.

But we do have a USB diskette drive for the Linux machine, so I can download the software and move it over with diskettes! 3.9MB at 720K is five bites. Actually because of the way the files are split up, it takes seven.

And THEN, we get to the point of writing the diskettes with the correct format (77 tracks, not 80, 1024 byte sectors, no interleave).

Wow. Don't diskettes take a huge amount of time to write and read?

Ta da.                                 

New MacBook, old data card

So anyway, I have a brand new (to me) MacBook for my playtime. And work, and stuff. It was a brilliant purchase from eBay (except when it arrived, it seemed to be missing a key) and I am delighted with it.

It took a little sorting out when I upgraded to El Capitan a couple of weeks ago, but I am very pleased.

Then, a couple of days ago I decided to log in when I was at a show in London, with my Virgin Media data card plugged in to the USB. Ah, no device. Tried again. Still no device. Now the USB port knows something is plugged in, and the package to install pops up on the screen, so its not a low level problem. Must be the software, I thought. I go Googling at home, can't find anything sensible, so I decided to phone Virgin Media.

I phoned the number on the web site for mobile data, and got through after a few minutes. I described my problem to the nice person on the phone. Hmm, let me transfer you to the technical department.

Oh, sorry they are busy. I'll just put you on hold, as I want to make sure I pass you over properly (la,l a, music, la, la) Sorry about the delay. To make sure I can pass you over, I need to take some details from you first.

(Go through process of saying no, I can't give you the phone number of the card as when I plug it in, it DOESN'T WORK - followed by my postcode, house number, Nicholas Sargeant - yes, you may call me Nick, the first two characters of my password etc).

Transfer to technical department. Describe problem again.

Technical department tell me that it's not a known problem, but it's usually an issue with Windows 7 migrating to Windows 10. I tell him I am using Mac OS X and I am on El Capitan now.  Ah, ok. Well, it's the same thing. The manufacturers can't keep updating device drivers, so we encourage customers to look at Mifi products now. Really? I ask .. having been Googling in the background. Well, I don't need Mifi, and it seems to be a little more expensive, but would be a lot easier than having a special launcher on the machine, so I say Please tell me more. Ah, yes sir, I'll just pass you over to our sales department.

Welcome to Virgin Media. So we can serve you better, please listen carefully to the following ...

Get through to another person. Lovely girl.

" I need to take some details from you first. " (My postcode, house number, Nicholas Sargeant - yes, you may call me Nick, the first two characters of my password etc). I'm interested in your Mifi products, and wondered if you would tell me something about them.

Yes sir. I will need to transfer you to Mobile Data to deal with your query though. Just let me pop you on hold ..

Yes sir. I am a little new to Mobile Data products, but I will do my best to help you.

Long conversation ensues, followed by me choosing a product I wanted, giving my credit card details and so on. Oh, sorry sir, that one is out of stock. We do have the 3GB per month model available for only 15 quid a month ..

Not convinced, I explained I would need to do some research and come back. Meanwhile would it be possible to cancel the contract on my USB stick, that DOESN'T WORK?

Yes sir, of course. I will just transfer you to Cancellations ..

My new USB stick comes from O2. Works fine out of the box, even on El Capitan on my Mac. They thoughtfully send me an email when I cross 80% of my data usage, so I can either squeeze my usage until month end, or I can buy an additional GB of data to tide me over. So far, I have managed to keep within the allowance. My only gripe is that while the contract comes with mobile wifi hotspots, they aren't all that prevalent, with one huge exception. The hospital where I spend most of my time at work ;-)
