Hi everyone
I picked up a vt102 from eBay that would not power on. I opened it up, cleaned it out and inspected everything.
I may have got lucky as the fuse holder was cracked and the fuse broken.
FYI if you need to replace it, the one below is nearly identical. You will need to solder one wire on (or add a crimp connector) as one lead is soldered on the OEM one. The other is just a crimp terminal connector which fits the new one. The fuse for 110 is a 1.25A
Now I have the vt102 turning on and I get a fairly clear picture with no burn in.
On the screen there is a flashing 4…which reading the technical manual appears to be a keyboard error - this makes sense as I do not have a keyboard.
Before I go on what is likely a very expensive hunt for a keyboard, can anyone confirm that this is indeed what it looks like with a keyboard unplugged?
Also any leads on a replacement keyboard would be appreciated, even if homebrew or non-authentic. I took a look online and it looks like someone converted one to usb, however the website with the actual info is now dead. Reading the tech manual, it seems possible to emulate (which is why I was hoping to see the code of the usb one) but this is a bit over my head. If it was a simple rs-232 protocol I do that with a pico and a max232 - but having a combined transit/receive line in addition to an integrated clock signal is a lot to digest.
