The modem is a cherised hand-down, but like many hand-downs it had its quirks. It came with dead speaker. I was in a hurry to get it working (and poor), so rather than buy a spare, I drilled the shield, wired an old 3.5mm jack and used an external speaker cone I'd mounted on a cardboard box.

 

This is an internal ISA bus modem, so it contains both a Hayes-compatible smart modem and a serial port adaptor for it. The white stickered chip in the foreground is almost certainly an Intel 8250 UART. The smaller one is a fully integrated serial smart modem controller. I mean, yes, there was large scale integration. It was the 90s, we weren't total savages.

 

the two smaller black packages on the left side are the address decoders that mapped the UART to COM1 or COM2. You set that using the two jumpers.

Magnetic core memory from the 50's.

Every ring = 1bit.

No way to fit my photo-archive on it! :-)

This is one of my earlier computers, an Apple 2c. The huge dot-matrix printer is on the right and the compact keyboard seems so alien compared to keyboards I'm more familiar with. Just below the monitor on the left, is the 5.25 inch disk drive. Now, there's some high-end technology for you!

Here's the inside. Yes, that's a passive backplane with a basic power supply and five cards. There's almost no logic in there, which makes sense, since this is a dumb modem. It just MOdulates the serial port levels to sound for the speaker and DEModulates the sound from the microphone to serial port levels.

 

It's built like something that's about to be launched to Mars.

This morning turned into some fun moving computers, or something like that.

 

We decomissioned an IT suite, meaning we had to strip down these 32 venerable HP DC7700 machines so they can make their long, long overdue visit to the recycling centre.

 

Then we had to move the 32 computers from the room next door into the one we just cleared.

 

All good fun.

 

This is in preparation for some demolition that will be happening that requires some teachers to move classrooms.

 

In January.

 

Maybe.

computers computer history "silicon valley"

In 1984 Sinclair launched the ZX Spectrum+. A fully suitable name, because the 'Plus' was nothing more then a face lifted normal ZX Spectrum, the big bang for Sinclair that was launched two years before.

 

The Spectrum+ tried to solve the biggest minus of all Sinclair computers so far: the awkward keyboard.
