Title: IBM 122-Key Model M (PT NO 1387001 - DATE 26JULY85 - ID NO 00219)
Post by: joc on Sun, 26 October 2014, 21:06:11: Hello, I found this unique IBM 122-key Model M. This is the first 122-key Model M I've seen with the old style barcode label. Also, this 122-key Model M has one of the lowest serial numbers I've seen on a Model M. I'm assuming that it's rare. I'll probably put together a Soarer's converter to check if it still works. Are there any keyboards similar to this one documented online? I couldn't find much information about it online.

that might be the earliest M I've seen

I know DV has a really early one too, but this is up there

nah mine's a 1390120 march 1986. The IBM I have that's really early is my F122 which is january 1984. It's ID number is 00363

of note is the serial number (ID number) of this one is even lower: there are only a few IBM keyboards I know of with serial numbers that low.

I'll have to look up the previous contender for oldest model M. i think killerbee had it. part number is 1386303 or 1386304

hal9000 has this (https://geekhack.org/index.php?action=dlattach;topic=60029.0;attach=69362;image) from this topic (https://geekhack.org/index.php?topic=60029.msg1381510#msg1381510)

killerbee's was from june 10 1985 serial number 01137

Note that buckling spring over membrane was introduced in december of 1984 on the wheelwriter typewriters.
