Re: How feasible is it to acquire an AT&T 56k 460 ACW for daily use?

Hi, 1) I can't help you that much on prices. I had a few that were somewhat dirty that I sold for about $50 not including shipping. I am not sure what any others have sold for, but I imagine a clean example would go for quite a bit more. 2) I am this Ben person so I can help you with the converter s...

Re: Custom Space Invader Keyboard - God Layout?

I see, it did have quite a few issues. It is unfortunate that recyclers often cut the cables on keyboards. Btw, I noticed the one "bodge" wire. There always seems to be one on the first go :P

Re: [Interest Check] FK-5001/9000 calculator replacement

Apologies for the lack of updates. May was unexpectedly busy. I am still moving forward on this when time allows. I will be building the new pcb revision this weekend and have made the majority of the code updates that will be required. Hopefully I will have a working demonstrator soon.

Re: Contest - $20, 48 hours - Guess the keyboards/terminals

You can use a mild abrasive like fine sand paper or steel wool. It may scuff up the soldermask a bit but won't damage if you don't over do it. You can also try a bit of vinegar and salt solution on swabs to carefully clean just the copper parts. You will then then to wipe with alcohol to remove any ...

Re: Liberty / Morrow BT1200A-1 review (SMK J-M0404 vintage linear)

When it passed through my hands, I took a peek and if I remember correctly, this used a simple serial protocol that sent ASCII character codes. This was pretty common for basic "dumb" terminals as which relayed ASCII data from the keyboard to the host and displayed ASCII data received from the host.

I feel like the offset display would bug me, although with a color matched piece of plastic or the like, that could be severely reduced.

Background Some time ago, I developed a replacement for the stock, failure prone calculator module in the Focus FK-9000. This project was essentially a "two" off that I made for myself and Chyros. You can see the module on Chyros' youtube channel in his "Project F" at around the 10:30 mark . In the...

Re: IBM System 9000 keyboard and picture of unknown Model F

Nice work on the research! I really wish more of these would turn up in the real world. I imagine the total number made was low and the due to their research/lab usage they didn't end up in the normal computer recycling pipeline when retired

Not sure I follow. What do you mean by "US English" layout being supported by ASCII? ASCII predates pretty much any keyboard layout.

Hypersphere's instructions are excellent. I will add that I find having some foam swabs in addition to cotton ones is useful as they come in several sizes and don't leave fibers on sharp edges.

Re: Making a Secure Keyboard

Some of the teensy boards have a microcontroller with a small amount of eeprom (1K), which is persistent, but no other persistent memory. More could be added by connecting an external eeprom or disk storage such as an SD card.
