Shiny model M backplates are mostly (but not always) found in keyboards from 1986 - 1987. I hardly see the shiny back plates on keyboards after 1988. For example https://clickykeyboards.com/product/1986-ibm-model-m-1390131-made-by-ibm-17-jun-86/ https://i2.wp.com/clickykeyboards.com/wp-content/uploa...

The buckling-spring and hammer assemblies in the Model M and the Model M2 are the same and they are interchangeable.

Nice keyboard! I remember the lore and the competitive hatred that Wang Industries had for IBM.. especially in this 1985 Super Bowl commercial. https://youtu.be/doaBK6ge9FU The Wang founder (Dr. An Wang) died in 1990 and then someone in Wang corporate in 1991 decided to use adopt the model M keyboar...

Neat find. Your 1397651 looks similar to this https://clickykeyboards.com/product/1991-dell-model-m-old-logo-1397651-07-19-91/ 1397651-001.jpg 1397651-002.jpg 1397651-003.jpg 1397651-004.jpg Back in 1991, Dell was a much smaller company than the ubiquitous company that it is known as today. I think ...

If you are already a fan of the IBM buckling spring model M keyboard (like the 1391401).. then you might consider the IBM 71G4644 model M. The 71G4644 shares many of the same parts as the buckling-spring model M keyboards.. but instead of 101 individual springs, it uses heavy rubber domes to remove ...

I would also recommend to leave it in place and do no harm. I have seen the layers glued together in many of the earliest model M keyboards like the 1390120's and 1390131's from 1986. Later models from 1988 - 1999 never had this as a build feature. (I might have two or three from 1987). Good news is...

Excellent model M cleaning and restoration job.

Industrial gray model M keyboards with the black badge with silver IBM logo looks particularly awesome.

May your 31-year old keyboard (2018-1987) have yet another 3 decades of life to look forward to.

Very clean, elegant and tastefully done. It is nice to see how much detail work it must have taken to apply masking tape to the internal barrel plate to ensure that the individual key stems do not stick or rub on the added layers of paint. Glad to see that you used 6mm long screws applied from the i...

IBM model F
IBM part # 4176203
Date: 27 SEP 84

weight without cable: 3.06 kg

Let me know if you need any reference weights and measurements for any of these keyboards

6110347 (122 key model F, IBM 3180?)
4176203 (83 key model F)
1395249 (50 key model M)

After IBM designed the Personal System/2 computers in the mid 1980's and built the model M with the Enhanced Keyboard layout as a standard, all the other PC manufacturers of the world then and now copied and cloned and model M and not the model F. ibm enhanced keyboard.jpg source: (1986) "Hardware N...

I have been exchanging emails with Marcin Wichary https://aresluna.org since June 2017. He had some very thoughtful questions about model M keyboards and we were happy to share our expertise, experiences, and anecdotes. It is always good to work with good storytellers who are careful about their cra...

Also.. since we are talking about prices from the 1980s, it is also important to factor in 25+ years of the cost of inflation of the US dollar. https://upload.wikimedia.org/wikipedia/commons/3/34/US_Consumer_Price_Index_Graph.svg Using online CPI calculator for US Bureau of Labor Statistics https://...

Shipping containers, industrial pallet jacks, and 48" x 40" x 36" double-walled cardboard boxes on wooden pallets.. all important components of effective keyboard inventory management.

Thinking about this a little bit more. I think many people have equated the terms "IBM Enhanced Keyboard" with "IBM model M keyboard". https://deskthority.net/wiki/IBM_Enhanced_Keyboard The IBM enhanced keyboard was a design change from the earlier 83-key keyboards used with the IBM-XT and the 84-ke...

Very interesting unicorn. Definitely the outer IBM box, the documentation, keyboard case plastics, IBM labels all look original for a 1986 model M keyboard that was packaged with an IBM PC. These pieces do not look like fakes. Based on these, I would have expected there to be a 1390120 model M keybo...

NO FUCKING WAY am I going to hard-mod one of the first Model Ms ever made xD .

This is a '93 Model M? But it's obviously the inner assembly from one M, put in one of Unicomp's surplus blue-logo Industrial cases (the only blue-logo Industrial anything, AFAIK)— For the record, another industrial model M keyboard with blue-logo would be the Model M-13 06H4173 with trackpoint. ht...

Without seeing additional photos, this is probably NOT a clear case of broken or missing plastic rivets. First, try to take off the key cap covers for the up and down keys and swap them with 2 other keys. It would be easy to determine if you just need replacement key caps. I have seen a few rare cas...

"There's an oddity about this keyboard that I only discovered during the disassembly: this particular SSK (1391472) has 1-piece keycaps EXCEPT the F and J keys, which are 2-piece (stem+cap). At first, I only noticed this about the F key, which made me think that perhaps someone had switched it, but ...

Among my favorite model M keyboards are those early ones from 1985 and 1986 with shiny curved "chromed" metal plates.

I have seen references to Compaq, Lexmark and NMB all using this technology in a few keyboards in the 1990s. https://youtu.be/UTWxEeX-QTU?t=2m25s Found this trademark info on US patent and trademark website http://tsdr.uspto.gov/documentviewer?caseId=sn74368270&docId=SPE20070820185932#docIndex=1&pag...

Great model M variant and nice model M bolt-mod.

Here is the original IBM product literature mentioning the model M keyboards with Erase-Eaze option.

Yes, we do have a limited number of spare black keys with white lettering for the Model M13 that are still in good condition. model-m-parts.jpg In addition, we keep alot of other original parts for many model M keyboards (1985 - 1999). If a specific part is not listed on our site, contact us directl...

That's interesting, I didn't know about the plate thickness. Now of course you'll have to weigh all the individual parts... :twisted: P.S. How many rivets fell off during those measurements? :mrgreen: No keyboards were harmed in the making of this analysis. Any missing rivets (less than 4-6) were d...
