NCR Tower 32-650 system - Freaknet Museum - museum.dyne.org/

This amazing gadget is a pen plotter, built from scrap parts. The plotting table is a direct-drive record turntable, salvaged from the dump. The pen is driven left and right by the carriage mechanism from a printer. The whole thing is driven from the laptop on the far right, via an Atmel ATmega32.

What lurks under the trapdoor of my ancient A1200!

 

Going by the date codes on the chips, this was made in 1994.

The coin cell is rechargeable to keep the RTC ticking ...

IBM PS/2 E, running the system configuration tool from the reference diskette

The interior of the game diskette package. The disk is not a 3.5" disk nor an Amstrad-type disk. It may be of the miniature disk format used by some old samplers, synthesisers and word processors.

In the 1980s, Acorn developed the ARM CPU (as seen in your iPhone) and a workstation operating system for it named RiscOS. The ARM CPU has evolved into a lot of tiny systems, and RiscOS has become almost free; here it is running on a tiny board named the BeagleBoard. It's a workstation that fits in a pocket.

SGI 4D320 VGX "Twin Tower"

Shot of my Amiga 2000 with her little friend the Iomega Zip 100 (SCSI). I've since moved the drive away from the monitor for fear of potential data corruption.

 

Those are real C= speakers, by the way. :)

Dumping the contents from the varius RL02 diskpack present in the museum archive, using a MicroVAX II clustered with a simh system with VMS, the old PDP 11/34 of the museum, and the RL02 drive from the "new" PDP 11/23.

SGI 4D320 VGX "Twin Tower"

I've been getting some home-made ZX Spectrum programs off cassettes that have been various lofts for decades. Amazingly, most still load. See github.com/blogmywiki/ZXSpectrum for files you can load in emulators.

Running a PDP11 emulator, talking to an ASR33 teletype. It's Unix, but not as we know it.

Assembled and running my PongClock.prc (which you can find here)

The program includes logic which disables the auto-off feature if it finds 2.75V or greater at startup.

This is my second PalmOS program, I wrote CountDown more than 10 years ago. Writing this one in 2010 wasn't easy, it may count as Retrocomputing. The tools I used back then were lost. I ended up using a Metrowerks CodeWarrier Lite I still had on CD. It won't even install on my new (Windows 7) laptop.

An Apple II fitted with a ZIF socket for easy installation of additional ROMs.
