@toney: I also bought a 8 digit hand held calculator.  It was 94 cents.

I never fail to find this sort of thing mind-boggling...

@ssidman: If you have the whole kit, and can get that one running again, a simple examination of the saved file should answer questions on compression techniques.

It depends -- the CASIO might uncompress the data into an ASCII format for upload to the PC, then re-compress it on the download ... as you say, if David can get it working, it will be interesting to take a look at the saved file...

Re: TI PS-6560i with 128K & RS232

@bwmetz0: This little beauty had a RS232 docking station for syncing with a PC, thus enabling me to keep CSV files with wiring/network/equipment details for pretty much everyone in the company.

It's amazing how fast things have changed -- I remember back in 1998 when I had a small office with a friend wherte we worked in the evenings after our day jobs. We had one 56K modem and a lying cable that we plugged ino the back of whichever machine we wanted to use to upload files to the Internet -- I was blown away when we worked out how to connect the machines together in such a way that either could access the Internet (one at a time) without having to move the modem cable LOL

Re: HP95 pocket MS-DOS PC

@traneus: I use an HP95 (vintage 1990) pocket MS-DOS PC for writing on camping trips where I don't have access to chargers. The HP95 runs for more than a week from a pair of alkaline AA cells...

Wow -- that's pretty darn good -- but why are you writing while on camping trips? You should be relaxing LOL

My dad bought one of these Casios (sometime early nineties), to store contacts and calendar items. Claimed it was much more efficient than the paper Time Manager he used.

Me and my brothers instantly started mocking him (as you can tell we're liberal eurotrash that have no respect for the elders:-), since we saw that it was extremely cumbersome to use. However he did not back down, so we sat back and waited for what must obviously come.

 

Lo and behold, within a week, I noticed the Casio on my fathers  desk.

with a post-it on it.

The post-it had an appointment scribbled down.

After 15 minutes of disrespectful pointing out how the logical conclusion must be that the thing was impractical and therefore useless, he gave in and went back to the Time Manager.

I bought a CASIO fx-300ES at Wam Mart last week.  It was $10.  I also bought a 8 digit hand held calculator.  It was 94 cents.

@Traneus...you certainly have yoruself well set up.

I got a PCMCIA slot for a desktop PC.  It fits in a 3.5" slot.  My plan was to use my work aircard on it to get internet (we get a 5GB allowance and I hardly use any for work).  However DSL has got so cheap I got that (also it lets the wife use it when I am at work).

Sometime I must try and get the HP Jornada going too, it's a lot more advanced than the Casio, probably more in line with yours.

HP95 add-ons

My HP95 has an infrared output to drive a printer, and a serial port to connect to a modem. I haven't used either of these ports.

Instead of a floppy disk, the HP95 has a PCMCIA slot which takes SRAM cards. These are the original PCMCIA battery-backed SRAM cards, not the later cardbus hard-drive-emulating flash cards. The HP95 works with SRAM cards up to 2 megabytes.

MS-DOS formats the SRAM card as if it was a floppy disk. The first 512 bytes of the SRAM are skipped, and the rest of the SRAM is formatted FAT-12 like a floppy disk.

I built hardware to copy the card SRAM data sequentially into an image file on my Linux box. I mount the image file as a FAT-12 device using the loopback filesystem, and then copy my writings from the mounted image file.

@Ssidman...thanks for that....will have a look tonight (our work net nanny won't let me there now :-)

As you say, the diary has a mode that it can autonomously send stuff out, so will try that.

Found this six year old blog after a 30 second Google search. Isn't the Internet scary? Nothing is forgotten. Anyway, it purports to have serial interface directions and schematics.

LATEST ARCHIVED BROADCAST

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
