Hey guys, you know what I just got given?

It took me a while to work out what it is. It calls itself a PD 
cartridge. But it turns out that if you slide the bit plastic shutter 
back, there's a CD-ROM inside it.

Wow! I haven't seen one of those for, like, years! Damn, surely they 
don't even *make* these any more. Heh. Maybe I should denate it to a 
museum or something? :-D

I think I still have some. From the days when optical disks started. I 
think they were physically compatible with existing optical disk (have 
some of those too) while internally they were just CDROMs. Best of both 
worlds. BTW last week I found an 8 inch floppy, anyone remember those?
I also have some tapes for a tape drive and probably we still have a 
20MB removable hard disk for a PDP-11 somewhere in the department.

Advanced! LOL.

Ooo, are those the "floppy" ones?

Guy at college was telling me how glad he was when those went out. 
Apparently the ladies used to like to fold them up (!!) to fit in their 
handbags - and then wonder why they didn't work the next day.

And who says stupidity is a modern phenominon?

I think you are referring to the 5 1/4 inch ones, at least those were 
more common when the concept of a PC was introduces. I really mean an 8 
inch one.

You bet.  Used to do system backups on an IBM System/34 using 8" 
diskettes that were loaded into a 10-disk magazine.

Have you ever seen a Laser Disk?  I used to watch videos on them.  They were basically
12" CDs.

I used to repair typesetting equipment that used 8" floppy drives.  We used to have to
break out an oscilloscope and Dysan disk occasionally to align them.  Those were the
days, huh?

They were indeed.  We had an 8" drive in our AS/400 because payroll data 
was on the S/34, and hours were tracked on the AS/400.

I remember doing backups on a PDP-11 as well once upon a time.  I think I 
was 12. :-)

Yeah. But analogue, appparently. No, I've never seen one, only heard 
about them...
