Decided to display the VAX-11/750 at the @revspace open day yesterday. All the hard work repairing it seems to have paid off, managed to get 14 hours of uptime out of it before shutting it down at the end of the day! #unix #retrocomputing #dec #vax11 #minicomputer #unixhistory #bsd

Row of historical computer equipment: Hp7475A plotter, VAX-11/750 with a VT100 terminal atop it, TU80 tape drive with two fujitsu 8" harddrives below it, VT55 terminal resting on a stack of club mate crates.

Screenshot of a telnet session on the VAX showing a 4.3BSD-Quasijarus shell session, uptime output 17:26 hours, 7 users, as well as a vmstat output and a (truncated) proces list

What am I doing today? Oh nothing, just strapping a tower cooler to my Intel SBC because it was getting too hot to touch before. #MiniComputer

A large aluminium tower heat sink screwed to a 3d printed bracket to attach it to the aluminium back plate of a small single board computer.

I used the University of Leeds' Prime 750 computer (then very new) in 1980 to write a programme in, if I remember correctly, Fortran 77. The editor I used did not automatically number lines and the default to move from one line to another was to type, eg, -7, if you wanted to move 7 lines up.

Does anybody recognise this editor. Could it have been "ed"?

If you know people with an interest in 1980s minicomputers would you mind boosting? Thanks.

I've had minicomputers on my mind lately, particularly the old PDP-11. I just came across a special issue of the Bell System Technical Journal about a minicomputer Bell Labs built to shoot down nuclear warheads

An illustration showing four system components, a flat panel long range radar at the top, a data-processing system to the upper left, a missile site radar (MSR) in the middle (the first three connected with squiggly communication lines with arrows at the end.

At the bottom right a short missile (SPRINT) and a long missile (SPARTAN) are linked to the MSR with a communications link.

I got tired of not finding antennas for this thing so I did what I do best and built some out of LEGO ✨ :blobfoxfloofreach:
(I encased the laptop antennas)

#SBC #miniComputer

Single-board computer in a rectangular metal case with antennas made of LEGO sticking out on both sides

Today at the #HomeComputerMuseum repair department, a big minicomputer-like thing from the early 80s. Made by Compudata, a Dutch company that would later rename itself to Tulip Computers. We haven't really been able to find anything about what it is, despite having the faceplate with a name on it.

Also, with it came a big chonk of a hard drive, capacity not known. The hard drive seemed to include controller hardware, and consisted of a whopping FOUR separate PCBs stacked on top of each other. Thankfully the top two could be tilted upwards. The hard drive has some electrical issues so we're not sure if it still works.

Not shown are an equally large second computer case, containing two 8-inch floppy drives.

#RetroComputing #Minicomputer #Compudata #TulipComputers

A large metal computer case, about 50 cm wide, with the cover off. The box is divided into two halves. On the left is an exposed power supply, with an 8 inch tape drive mounted below it. On the right are the two motherboards, one hidden below the other. Below the motherboards are a large open space to fit the hard drive.

The face plate of the computer case, which says "CD-MULTINET 2000".

The hard drive unit from the computer. It is an 8 inch model like the tape drive. Two of the PCBs are folded upwards, the remaining two are still attached to the drive. A large hub for the drive mechanism is also visible, as well as the brake pad that holds the platters still while the drive is turned off.

A sticker on the hard drive showing the information about the drive.

@soulscircuit They look amazing! 🤩 I really love the design, but I do have one suggestion: would it be possible to move the ports to the top next to the screen? Having them on the bottom left near the keyboard might be a bit inconvenient or annoying for left-handed users who hold the console with their left hand. 🤔

As for the color, I'm a bit boring, but I think a metallic silver or gray (like options 2 or 6) would look great. What do you think? 🤗 #PortableConsole #Pilet5 #minicomputer

A new module is about to drop. Any idea what it might be?

#Ireland-based #RetroComputing and #VintageComputing folks might be interested in a stash of #IBM, #DEC, #Wyse and other #mainframe and #minicomputer #GreenScreen #terminals, most dating from the 1980s and 1990s (without keyboards, unfortunately), as well as copious sealed #Windows95 CDs ("with USB support"), sealed 3½ inch #FloppyDisks, sealed and unsealed memory modules in the tens of megabytes range, sealed IBM branded PS/2 ball mice, vintage toner cartridges and ink ribbons. There's a single #Amstrad monitor for use with the #CPC454, an intriguing #Apricot-branded machine and some VGA-era monitors. Many of them will need work. There's a functioning #Windows98 machine.

The stash is located in a shed in the village of Rathdowney. You can contact the seller via adverts to arrange to see it: https://touch.adverts.ie/monitors/vintage-monitors-mobile-phones-etc/33899224

The seller is prepared to power on devices for you. I left with only a few handfuls of floppies as I already have more DEC terminals than I need.

[edit: 3¼ to 3½]

Four CRT monitors, probably all green-screen terminals. One of them is a DEC VT220 terminal.

A pile of five computer terminals. The one in the foreground has a brown bezel and may date from the 1970s.

Olivetti and Mitsubishi branded CRT terminals.

Hi, wenn ich einen #Minicomputer betreiben möchte, der
- #Python ausführen kann
- #WLAN hat
- Programmausführungen plannen kann (#cron oder Aufgabenplanung)
- leicht zu erlernen ist
- quasi keinen #Stromverbrauch hat
- 7 x 24 laufen kann
- mit Sensoren wie Temperatur, Luftfeuchtigkeit etc. arbeiten kann (evtl. direkt anschließen?)

was würdet ihr mir empfehlen?

I think I will attempt to reply to the initial post of my WordPress page, whenever I write a new post concerning the design of my #DWMC16 #DIWhy #Minicomputer.

Which for some reason does not manage to ever get a clickable link... >_>
