Am 18.5. radle ich (evt. mit ein paar @Datenpunks) von den @acmelabs zum Computermuseum Bielefeld in Senne. Alle sind eingeladen, einfach mitzuradeln!

Wann? Sonntag, 18. Mai 2025, 13:00 Uhr
Wo? Acme Labs, Mühlenstraße 5, 33607 Bielefeld (Nähe Ravensberger Park)

Die Hinfahrt dauert etwa eine Stunde bei gemächlichen Tempo. Nehmt ein Getränk und einen Snack mit! Ich fahre lieber Waldwege als Straße, also nehmt eher nicht das Rennrad.

Spätestens 18 Uhr fahren wir mit dem Rad zurück. Vielleicht gehen manche von uns auf der Rückfahrt italienisch essen im Dakota Inn (Am Flugplatz 1).

Dank für den Hinweis auf dieses Museum gebührt @njumaen.

Today we're expecting a small group of visitors at our museum. I've taken this opportunity to tidy things up a bit and fire up some machines. Here's a look at our Sinclair series in the exhibition.
#ComputerMuseum #RetroComputing

Yesterday I configured two VMs inside #proxmox to run some museums specific software. Learned some new stuff in this great software, i.e. store the backups in a NFS share on a second machine.
First is #PartDB as inventory software for our whole stuff including the library like books and software. And second is #Omeka for additional information about the machines in our exhibition.
It looks like we'll have a long way to go to get our entire inventory in order.

Welcome to the Update Computer Club!

International Open #Hackerspace Day
March 29, 15:00 – open end
Svartbäcksgatan 65, 753 33 #Uppsala

The event is #free and open to everyone.

Programme:
* Take a tour of the space including our interactive #computermuseum.
* Try out, build, design and jam on #synthesisers together with other enthusiasts.
* Beat the highscore on our Asteroids #arcade game.

Today, I visited the Heinz Nixdorf Museum in Paderborn and was amazed. What a huge place! Defo worth another visit for me.

And finally the #TexasInstruments #TI994A is remounted in it's case. And working well after half an hour burn in test only with the circuit boards.

#HewlettPackard #OmniBook #HP600C. What a nice cute little machine. Boots fine from HDD with Win3.11. The most funny thing is the inbound mouse, which flips right out of the case with a button.

Finished my work at the #TexasInstruments #TI994A and at the cutting software to produce a video of it. Sorry, only in German. But it is possible with options dialog to choose a specific undertitle language for automatic translation. And it's not 34€ for the bending tool, it's 3 to 4€

At our annual member meeting yesterday we all plan to make a bit more documentation about our daily work for the museum. Our youtube channel needs significantly more input for staying up to date with the progress. We will see how well this works in the new year. I for myself will start with the replacement of the video RAM of the #TexasInstruments #TI994A
#ComputerMuseum #RetroComputing

We're one step further, the #KneisnerM100 can now finally be programmed in a high-level language like #Pascal.
Say hello, m100 - see picture ;)
Not that we do it, but we can now. It was really tricky to put software to the hdd, but I found a tool called 22disk, which can write from and to #IMSTurboDOS.
#RetroComputing #ComputerMuseum

Today I started to repair our Texas Instruments #TI994A. It shows the wrong characters on startup. I'm unsure, maybe one of the ugly, soldered 4116 the video RAM. Main ROM rather unlikely, because it boots up fine to the start screen.
#RetroComputing #ComputerMuseum

I do several experiments to get a bit more HDD space for the #TurboDOS in the #KneisnerM100. My attempts some time ago were not so successful, but I had an idea last night.

After fiddeling around to find a good terminal emulation program for simulating a #TeleVideo terminal I'm gone back to the roots. ZOC was an alternative, but it does not run under #Linux.
It's also a kind of #RetroComputing to control the #KneisnerM100 with an old DOS program Now the display positions are correct and no annoying ctrl sequences as with VT100 or ANSI.
#ComputerMuseum

Looking through our store of MFM harddisks to find a compatible one, which is bigger as 5MB. Found one Rodtime RO-204, but with bearing damage. Horrible loud and not so reliable at the end. Searching ended with Seagate ST-412 which is with 10MB big enough for the needs of a #Z80 system with a TPA of ~44 kB driven.

Retro-Nerds aufgepasst! Heute hat das Bielefelder Computermuseum (https://bicomm.de) von 14:00 bis 18:00 Uhr geöffnet! Taucht ein in die Geschichte der Computer und erlebt Kult-Geräte aus vergangenen Zeiten. Ein Muss für Nerds, Gamer & Retro-Liebhaber! #Bielefeld #Computermuseum #RetroComputing - Ich werde auch gleich da sein!

Additional news about the #IMSAI8080 clone. Boot from HDD is the past and done. But booting from A: with GOTEK FlashFloppy as 5" ~800k is the next step of evolution. I also connected the original #TVI912C terminal for best compatibility.
On Saturday I'll look for a bigger compatible Winchester drive. Maybe there is something in stock to pimp it up a bit.

Yesterday my media history master courses visited the "#Rechenwerk Halle" museum - a huge collection of #GDR computer hardware and software.

Here you can find a foto documentation of the excursion:

Put the childs in front of an #Amiga500 and load #Lemmings for them is always a good idea. And from the idea and game humor so much better than today's search-and-destroy games.
