Early Industrial Model M

[Falkenroth]

Good evening,

I took some pictures of that early Industrial Model M that came with an IBM 5170 system I purchased recently. The pervious owner said he almost threw it away along with the 5153 monitor. Well they both survived and here are some keyboard photos for those who might want to check it out.

Best Regards

That is one great looking keyboard! This early industrial model, along with the black M13, are arguably the best looking ones in the entire Model M range.

The gray doesn't look quite as (for lack of a better word) corny as the off-white/beige you see with so many retro keyboards. That color is a good middle ground between slick and retro.Gotta' love that IBM badge in the top right-hand corner too!

CONGRATUALTIONS!!!

This is getting competitive fast!

For me, while those are great, the best looks are the SSKs. Pity there wasn’t a white on black SSK, that would be the big little boss.

Those are pretty cool too, but still no black M13 SSK. The True Maverick.

Regrettably I am missing an Industrial SSK.

Getting better.

Can’t anyone do that with SSKs? Has there been no chop?

I took some pictures of that early Industrial Model M that came with an IBM 5170 system I purchased recently.

Interesting. Was the 5170 a standard model or 'industrialised' in some way? If you're wondering what it originally came with - IBM 7531 Industrial Computer, as per IBM doc ZA86-0135. Technically, that was an industrial version of 5170 internally but was a tower computer instead. Anyway, there are also some rest of world versions of this keyboard mentioned in that doc too:

* 1388069 - Spanish
* 1388071 - Italian
* 1388073 - German
* 1388075 - French
* 1388077 - UK English

What's interesting is that ISO 7531/7532 black-square industrial Model Ms with similar P/Ns have been found before but are consistently minus 1. For example, a 1388072 German and 1388076 UK English are known. The well-known US ANSI black-square industrial Model M is quite different at 1388032. Not sure why that is.

Just a standard IBM 5170 from what I can tell. I haven't actually dug into much as of yet. Don't know how the keyboard ended up with the computer. I was told from the seller he was selling it for the original owner. Who knows.

So it it originally came with a IBM 7531 or 7532. Interesting. You would think there would be more survivors. Thanks for the info.

One other with an odd part number that was not added to the wiki

https://www.modelfkeyboards.com/product ... 1-1388032/

"Part number 1388081 (a factory customized version of the 1388032 – it appears like the production run was so small that IBM just affixed the part number label over what is likely part 1388032!). The only noticeable difference I can see is the square silver logo on this keyboard instead of the square black logo on the 1388032."

Is it normal to have those notches above the date sticker? After I posted this I went and looked and it appears it is normal and my keyboard above is the odd one out. Interesting

It seems that these notches are not present until the tail end of 1985.

[Falkenroth]

Thanks for digging those up. I saw around 1995 on some Lexmark keyboards the holes were also filled back in. Probably around the time they filled the speaker also. This is fun.

One day apart. That's awesome.

I have a feeling this part number had a very short run seeing we only know of two so far.

Thanks for sharing.

[JP!]

Since there are no pictures of the inside for this part number I figured I would share what I have.

The first thing I noticed about the inside of this board is that the metal plate is bolted to the frame unlike later Model M's which you could just take out. This one is bolted on the left side unlike the example that Chyros has which is bolted on the right side.

Besides these minor alterations noted earlier, the top and bottom case appear standard for full swing production for 1985 and onward. Even earlier examples such as the one Chyros has do not have as much reinforcement to secure the keyboard assembly.

Very nice.

Thanks for posting some photo's. I will have to open mine up one of these days and compare.

Need to check to see what the rivet condition is anyways. Typing feels good so I don't expect to be missing much.
