If you wasn't aware, around about now is pretty special for keyboards as this is the season that one of the most iconic keyboards is having its 40th birthday! The IBM Enhanced Keyboard (101/102-key Model M) is known for nailing the ANSI and ISO physical layouts sans super keys and the modern...

I haven't tried this in particular, but I have an idea of what to do. The membrane assembly's keymatrix (16 columns, 8 rows) is the same between the two designs (which is true for IBM Enhanced Keyboards even regardless of ANSI versus ISO, terminal versus PC, until ~1995 when this type of PCB was...

I managed to miss that when I tried to search... Doh. Anyway, thank you! Glad to see one.

P/N 1394417 is a 103-key Enhanced Keyboard, so it doesn't have extra (physical function) keys like a 122-key Converged Keyboard would. Pretty much all Enhanced Keyboards of that era (ones that uses Triomate sockets on their controller cards) use the same basic membrane assembly design. The only...

Hello! Yesterday, I was doing a bit of research into IBM x Wang Laboratories to help describe a Wang-branded Model M Enhanced Keyboard variant to go on my website (part number 1397721). Naturally, I ran into articles explaining how by June 1991, a now-struggling Wang turned to IBM for investment...

Hello! Based on the keys you have mentioned, it sounds like it's a membrane/ribbon cable issue. The four keys you gave as an example aren't random, they all share a keymatrix (the 'grid-looking' circuit each switch position is wired into) row trace. On my website, I have a keymatrix simulator...

Are you sure it isn't the Belkin itself beeping? Whilst I couldn't (quickly) find something mentioning this specific behaviour, on page 17 of its manual, it mentions the PRO2 PS/2 can beep for some things, so it might just be an undocumented feature. Most Model Ms don't have anything inside...

Thanks everyone for the warm welcome! Tell me about it. This was the extent of my collection just before COVID. I've since sold and bought a few more since then - my current favourites/I have out of storage are 365ED (favourite laptop keyboard - IBM Model M6-1), 240, 570, A30p (stunning...

Hello there, I'm Kali (aka, Admiral Shark), a vintage computing, typewriter and keyboards enthusiast from Wales, a small but beautiful country inside the UK full of castles and sheep! My interests are mostly IBM-related. I went through high school with what was already at the time becoming...

Yeah, that's one of the professionally-made ones like what orihalcon/Barcode Maverick used to also sell on eBay. Very neat looking, but you would have to ruin its casing to look at its internals, so let's focus on the keyboard first. (For future reference) P/N 1389162 is an IBM 3192 Color...

Could you tell us exactly what keyboard you have, please? The part number (the usually 7-digit number that should be prominent on the back) would suffice or photos if this is missing. There are many different Model M variants, but assuming it's an ordinary 101 or 102 key Model M Enhanced...

Part number 1389162 is an IBM 3192 Color Graphics Display Station Typewriter Keyboard (IBM 3270 family). I've also seen examples with IBM 3179 Color Graphics Display Stations as well since the keyboard should be electrically compatible with both. It is what's commonly called a "battleship" by...

Aye, I'm familiar with them. They've been in the business for a while and are amongst the earliest professional "bolt modders". Brandon (the person behind it) has been helpful with information and photos for my website in fact. Sound guy. But the prices they offer only compounds the hill Unicomp...

The case materials and weight are certainly different, but overall I think Unicomp keyboards are still very good. The switches themselves aren't purposely different, but some difference in key feel can be explained by a known change in blanket (the rubbery sheet between the buckling springs and...

Hope you enjoyed! Thanks! To be honest, what comes out of the terminal presently goes over my head (it's something I'm hoping to learn in the future). Looking at the scancode dictionaries in 5250_terminal.py though, that seems to indeed by the original scancode set used by IBM 5251/5252...
