Can someone identify this S100 SRAM card? I can tell that it's a 16K SRAM
board made up of MM2114 chips. Virtual beer to the first person who
guesses where I found it.

Oggetto: IBM RT memory boards
I've got 4 4Mx32 memory boards here from an old RT
(AFAIR) in case anybody has a use for them.
Each board has 8 512Kx40 (32 bits + 8 ECC) modules
(20 pcs. 4x256).
Edge connector is DS 42+49

I have an RT and may be interested.

Yes, as usual, all such claims are meaningless without term definitions.
What Murray was referring to was arguably the first PERSONAL computer
store, and run as a retail storefront.
IBM did do some retail sales, although they might not have called it
"retail", out of their building.
Even "first" and "store" could use some restrictive definition:
Do sales out of a living room count?
garage?
corner of another kind of store?
(there already seems to be an exclusion of mail-order)
If a grocery store clears space in an aisle does that count?
Did Ed Roberts have a front counter, and handle walk-in?
Assembled working systems? or do kits count?
Signing lease?
Acquiring retail inventory?
Opening of doors to the public?
First retail sale?
First Order? or
First Delivery?

You were very nice to try and work with the person; if they couldn't take that
on board, and in return come to some agreement that you could be happy with,
they're being some combinations of greedy and unreasonable.
I have to agree with other people: an open auction was held, and the value of
the item was determined by that to be.... $5. End of story.

The AC capacitor attached to the ferroresonant transformer can have a
spectacular failure mode where it hisses, sparks, and sprays (probably PCB
laden) oil on everything. As you said, all that will happen is the output
voltage goes low and it probably blows a fuse.

5 reference manuals to give away:
- 64 Sound and Graphics
- Machine Language for the Commodore 64, 128, and Other Commodore Computers
- Commodore 128 Reference Guide for Programmers
- Commodore 128 Assembly Language Programming
- Mapping the Commodore 128
They're in good shape! Pic here:

I'm willing to mail them within Canada or the US. I'd love to see these go
to someone who'll appreciate them. Remove the Commodore computer names and
email me at neilVIC20harvey at gmailC64.com
be interesting to see a list of the first 10 shops?
is there any chronology out there?

I have some slides of the IBM Customer Center from 1980, recently
scanned and I need to put them online. Yes, you could buy things like
system 36/38, Displaywriters, typewriters, printers, etc. Just before
the IBM PC. By 1980 the portable 5100 was not present, but I am sure
you could buy a 5100 from a customer center in 1975. Good point. I
think the original poster was referring to one of the first
independent microcomputer stores. There is a huge bias assumption
towards "first [micro]computer" whatever, conveniently ignoring the
huge volume of mini and mainframes sold at the same time.
