? KIM1-Replika ? Dachte gar nicht , dass der Russe auch die 6502-CPU geklont hat.
Das Teil hat mit KIM-1 absolut nix zu tun. Das ist nur ein 8080 SBC.
Sure, but apart from that, isn't it beautiful?

Die hässlichen Taster sind so eingebaut, dass man diese mittels 3D-Druck kaschieren und anschließend mit einem Label überkleben kann. Ist also zu retten, der knuffige Rechner.
Did you take it? Ebay just notified me that the item was deleted....

I tried this neat trick, writing diskettes with the RX50 attached to my AHA1542.
I made all the diskettes that are around.
Quiet sadly, no graphics extension means no ReGis...
I managed to write some images with Kryoflux and a normal PC 1.2MB drive iirc, but compatibility seems to be "on the edge" (not all copies worked).
Yes, I have found that the Teledisk images on the web are readable on the RX50 written with a normal 1.2MB drive on PC, but when I tried to write the IMD files that were imaged on RX50 drives, I have failed miserably. Another cool thing is RainDOS, that let's you read/write DOS formatted 400k SS80 floppies in a normal 1.2MB drive.

Im a little bit torn about him. Call me envious and yes, sure, casually having an Austin-Healey in your ballroom size garage behind your super rare mainframe next to some other sports car is not a east german kids childhood, but also hes... i don't know. Curious Mark also repairs more rare HP stuff a day then ill ever have, but with him im cool. Its the personality of them, I think.
The point is, regardless of their personalities, they both have - and repair - very rare and unusual machines. So its very nice to see, that some of us - like Nils - also have their hands on such treasures. That's why we are all here. Keep on going nilseuropa and let us know if you also get the UCSD Pascal OS up and running at some point in time.

NTSC?
There should be colors, in fact some programs can output even more colors than the normal CGA palette through artifacting.

VR201
and, done.

I have fixed the memexp. card, now it can run Concurrent CP/M-86 too.
Now onto the peripherals. LK201.
Initial state:
Care
Result
Hand painted keys
Tada

* PSU fixed
* keyboard functional
* rx50 spindle speed adjusted
* we have got liftoff
finally passed
sweet shell o-mine

I will attempt to restore this beaten up DEC Rainbow 100.
I guess I'll have to try one of the retro-bright techniques at the end...
VR201 too has seen better days for sure. Cataracts...
Came with a totally used up LK201. Keys are stuck, labeling worn down.There is an entire living ecosystem inside.
Wow this looks "interesting". Luckily my Rainbow didn't have these Issues inside, but the Monitor had the same Problem. Hence I created an Adapter to connect the keyboard directly to the computer and use a regular composite monitor (http://www.pocon.at/pic/rep19a.jpg).

Verdammt, nun habe ich’s doch getan, wahrscheinlich viel zu teuer und ohne Funktion, ich war aber so fasziniert…fast wie im Rausch ☺️ Mal sehen ob überhaupt und wann ich ihn zum Leben erwecken kann
looking pretty good

Usagi ( https://www.youtube.com/watch?v=Cj3UIqvTReg ) refers to this sync separator:

I just read your other post on the VT240
Seems like we are in the same shoes, looking for a VR241 substitute, right? -
It looks like it is out of sync. Have you tried it with S-Video or Composite?
Manual attached.

What are you up to? Lost your nuclear warhead in the shed?
Hah! You'll be the first to know when I find it, I promise
No worries, I'll know if it comes online; the big red button on my desk will light up.

War innerhalb von 24 Stunden bei mir in Californien - Made in Germany! Guter Preis!
Verkauft sich wohl gut bei Amazon momentan und ist schon im Lager vor Ort... warum wohl?
Auch Jod-Tabletten verkaufen sich bestens... hoffen wir mal dass wir sie nicht demnächst brauchen!
Nicht so ernst nehmen...

Yes, currently for testing purposes I have connected the DO directly, but the problem seems like a capacitive crosstalk from the clock line. It can very well be grounding or routing issue on the panel. We have to get rid of those spikes, either with a small resistor at the source plus a capacitor or with a fast rectifier. Or we could route the clock differently and filtering it cold with a small capacitor.
Anyhow, PC-Rath_de thank you very much for the support, I think we are getting close to the final design.

PC-Rath_de has sent me components and a batch from the new PCBs.
The wiring in the last revision is correct.
Power over parallel port is functioning flawlessly.
The TXB0104 level shifter is also good, BUT
on the SD Card MISO, there are some spikes that translate badly over the PC.
We need an RC filter on that line, and it will work.
Here is my build:

Heute habe ich noch ein bisschen was in der Scheune meines guten Freundes gefunden.
Das Zenith ZDS-625nl Notebook läuft leider nicht an, das Netzteil funktioniert soweit. Mal sehen ob ich das noch irgendwie retten kann.
Die meisten anderen alten Computer und Festplatten hatte ich bereits früher mitgenommen.
Jetzt liegen in der Scheune nur noch meist halb geschlachtete und defekte PC-Kompatible vom Typ 80486er und neuer oder wir kommen nicht dran, da zu viel andere Dinge davor liegen und stehen...
Mein allererster Laptop war ein Zenith 433VL. Ich habe ihn immer noch. Ich habe ihn letztes Jahr überholt, aber die Tastatur ist nicht mehr zu retten. Falls Du dich entscheidest, diesen aufzugeben, würde ich ihn gerne nehmen. So weit ich weiß, ist die Tastatur kompatibel.

So Fazit:
Es läuft nicht. Jeder Kontakt ist geprüft. Mainboard ist mit K6-233 Mhz, getestet wurde mit ECP und SPP auf Standartport.
Karte ist eine 8GB NoName, 5V und 3,3V sind stabil.
Ich gehe davon aus, dass der Treiber mit /d und ohne Portangaben automatisch Laufwerk 1 und Port 378 nimmt? Ich kann allerdings auch keine 5V auf den Parallelpins 5,6,7,8,9 messen?
Edit: ich glaube den Fehler gefunden zu haben: Die Pinbelegung war für weiblich, ich habe männlich aufgelötet und somit ist 1=13 und 13=1
Default port base is 0x378 -- ok
There should be 5V on pins 5,6,7,8,9 -- failDid you create a 32MB partition that is FAT16 formatted on the card?
Also, I can take a look at one of the KITs.
You use DB25F, i use DB25M. I fixed it and use Female + Gender changer
3,8V on pin 5,6,7,8,9 after driver load (it will not work to power it on this computer, so i use USB-C, 5V ok, 3,3V ok).
One logical 32MB FAT16 on NoName-TF and one primary 32MB FAT16 on Sandisk-TF
Then i see the sd port is turn around. So i fixed it and test every sd contact to chip and every IEEE contact to chip. All ok, but don´t work.
Now i test the sd card again (ok) and replace the TXB-Chip. Same problem.
If your circuit plan is right, it can only be, that the TXB can´t do his job (could you please check plan?)
Yes, please give me your adress and i send it to you. Did you have a 25p gender changer or 25p cable (because it would be my last one?)
PM

The Portable Paper
I have not yet tried to power it. I hope the battery didn't spill ( it is a sealed gel, so it should be just fine and very dead ) I read that these are extremely reliable.
Does anyone have documentation for a HP-IL to USB interface or drive emulator?
