BlaudioHi #Fediverse, ich suche Menschen die sich mit dem P8000 auskennen, ein alter Computer aus der DDR.

Herzlichen Dank!
Bitte nicht nachlassen.
Großartig.
Auch bei der @guug_de gibt es ggf. im Sommerworkshop (evtl. 8/25) einen Vortrag zu IT-Archäology.
@stefanhoeltgen ist als DER Retro Guru weiter an der Forschung v.a. #Basic Games (Richtig Stefan?)

Christian Pietsch 🍑Wer braucht noch fabrikneue #Z80-CPUs? Bis zum 14. Juni 2024 könnt ihr die letzten ihrer Art bei #Zilog bestellen.
Ich bin berührt davon, dass der #Mikroprozessor, auf dem ich 1986 in der DDR zu programmieren anfing, immer noch hergestellt wird.
Der Vater eines Schulfreunds arbeitete im VEB Mikroelektronik »Wilhelm Pieck« Mühlhausen, wo der KC 85/2 hergestellt wurde. In dem steckten der Z80-Klon #U880 aus dem Funkwerk Erfurt und ein BASIC-Modul.

steve#retrocomputing-Frage:
Warum hat die #DDR mit dem #U880 einen #Z80 nachgebaut, aber keinen #mos6502?
@Rp12Biker 
Early Sunday was used to solder the last lines of the #KramerMC memory expansion. All lines are beeped, correct and not shorted. Now I have to wait for my memSIM2, which is in repair in the moment. The voltage regulator was melted, no one knows exactly why.

After some searching I found the problem in #KramerMC. The #DS8286 on the cpu board gets in the way. In addition, it is installed incorrectly because the inputs and outputs are bridged. When I leave the socket empty it runs fine. Wonder if the computer ever worked the way it was intended.
Since I still had two of the plug-in contacts for the bus system in stock, I'm starting to build a RAM expansion to 64k. With address decoding to spare out 0000-0fff (ROM 2732) and 0fc00-ffff (display RAM). Because of the simplicity I decided to use 64k static RAM.
I'm also curious if the buddy might bring a new CPU board today, I'll be surprised.

You like some #KramerMC news? After the last try it doesn't work properly again. Which doesn't surprise me with the catastrophic condition of the CPU board. I'm tired of looking for broken wires/cuts again and again. We decided that a colleague in the museum would etch the whole thing again from scratch. And I would then build a "new old" one, of course with the original parts.
At the moment I'm revising the layout scanned in 1200 dpi in GIMP. It's always a bit of a loss when it's 35 years old and printed on extreme eco-friendly paper.

Today's afternoon in the museum wasn't really successful at all. I carried my EPROM simulator (memSIM2) with me to make a few tests with the real #KramerMC. But the beast wasn't thankful using it after a sleep of two years. Nothing broke, but it doesn't do what it supposed to do. A small test program filling the CRT memory with various characters. But I used the time and revised my git repo so that now all required programs under DOS and Linux with their instructions are part of it.
But I won't give up that easily. But the others asked me what I would do if one day the computer ran without errors 😂
