Hi,
I have one of the earliest IBM PCs. I don't know if this is something
you would be interested or not. As I recall, it was upgraded from 64k
of memory to 192 and it has a single-sided 5 1/4 disk drive. It is in
my mother's attic in Baltimore.

Note from the description that it is probably NOT "one of the
earliest" which had a motherboard with 16K chips and was available with as
little as 16K, upgradeable to 64K. But it COULD be one such, and later
had a 128K RAM card added.

I'm pretty sure that the single sided drives were long gone by the time
the 256K motherboard came out.
Of course, I've already proven the worth of my memory, so. . . :)

Good point

I really don't remember the IBM sequence, since I used aftermarket drives
(same Tandon drives for ~$200 v IBM's $540)
I do remember that I was using double sided drives with the "leaked" patch
for quite a while before IBM made them available along with support in
PC-DOS 1.10.
I have no idea when they changed the motherboard from 16-64K to 64-256K.
For the machine in question, the 64K to 192K upgrade could be either:
1) filling two more rows of RAM on a 64-256K motherboard
2) adding a 128K RAM card to an already full 16-64K motherboard.
BTW, when somebody says "64K motherboard", do they mean the 16-64K or the
64-256K?
Did IBM ever OFFICIALLY support the 640K conversion of the 64-256K board?

Not really. Somewhere I have an old IBM order form and it shows that you could get a
lot more variations of IBM PCs than you'd expect. Including one or two SS or DS
drives, various cards, different amounts of RAM, etc. There were quite a few
combinations.
Despite my sarcasm I too am fond of the IBM PC. I regard it as THE single machine that
legitamized the entire personal computer movement. Altairs and all the rest had some
significance but it was the IBM PC that was the first truely usable machine for anyone
other than the hobbiest/hacker/programmer. It's just that there are so many of them
out there that I get tired of them. I just pitched two a couple of days ago and I still
have an early 64k model w/ 48k RAM and a monochrome monitor.

I contacted the email listed but haven't yet heard back about this
historical old machine.
I, for one (and maybe the only one, it seems) have a lot of respect for
PCs (PeeCees) and what they mean to the industry as a whole. I can
sympathize with some of those that might have some contempt for the
"typical" PC user or who may not appreciate the role of the PC today,
but I recognize the power that they have helped disseminate and their
place in history, at least.
I'll always add another old orphan to my collection.

Actually, I have a 64k cassette port IBM PC in my collection. It was
given to me by an older gentleman, a doctor who had purchased it new,
but was scared of it. The original MDA display that has to be plugged
into the pass thru on the power suppy and an oroginal IBM keyboard that
sound and feels like a Selectric typewriter was included. It has spent
the first 20 years of it's life sitting on a table, covered with a heavy
vinyl cover. It's as dust free as new inside. I estimate it's probably
only had a few minutes run time in it's entire existance. I fire it up
for a couple of hours each year at our office as part of an exhibition
of our medical software, from beginning to present day.
