Want th have an (emulated) Elf?
Look at the screenshots at the bottom of the page![^] Do you see Tiny BASIC?
There is no screenshot, but the emulator should also have an image of one of my first running programs for the Elf II.
I have lived with several Zen masters - all of them were cats.
His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

Use it as a decoupler for the plasma relays.

I would say it is time to get a new board and solder anything anew... The components (like the ROM) may be in good order, but an old, trembling connection may fry all...
And in any case - do a copy of the ROM content... It may come handy if the ROM dies despite all your effort...

In those days they actually were so nice and printed a hex dump of the ROM on the back of the schematic. Still, the first thing I did was to save the content of the ROM onto a cassette tape - using the code in the ROM. When I find the time, I will sample a WAV file from the tape and import the code to my PC. Then I can make a disassembly and extract some code which I am going to need.
First I get my new Elf running, then the old Elf gets an overhaul. 40 year old bus connectors obviously tend to be a little loose.

Yes, we already know you are a wizard, now you are just showing off.

You mean this is not the wizards' guild here?
Nobody here reads books which no normal people can understand?
Nobody here then does stuff which normal people don't understand?
Then no computers do things which normal people don't understand?
Nobody here then comments the results in a way that normal people will not understand?
Nobody here who those normal people don't expect miracles of every day?

Nah. Showing off is just for those normal people. Here I hope to find someone who understands what I'm writing about.

Yes we do - but now your doing stuff that we non-normal people don't understand.
There is a limit you know!. (or at least there ought to be).

Look at a computer magazine from 1980[^] and see for yourself how much wizardry has changed since then. Let me assure you that this used to be fairly common knowledge.
I had this issue back when it was new and read that article about those new shiny 16 bit processors.

I remember in the days of the Commodore PET, when chips weren't soldered onto the motherboard but were mounted in whatever-you-call-it thingies that it made it easy to replace the chips, every 6 months or so, when something stopped working, I'd lift up the lid and make sure all the chips were fully seated, and connectors given a wiggle, and presto, the problem would be solved for another 6 months or so of thermal cycling.

Heck, if it's that old, I might even have one in a box somewhere around here, along with the data sheet. What's the part number?

All the usual suspects claim to have a datasheet, but once they have lured you to their pages, they admit that they don't have it.
Edit: Found a datasheet[^]

Man, even with the correct wording, that sentence is so run on an obfuscated, it's no wonder software development sucks so much nowadays, what with communication like that.
And yes, while I woke up on the right side of the bed, by the time I'd read through the morning emails at work, I can definitely say there was a mood transition to "why the pluck do I work at this job? I just want it to pluck off!" The irony -- poor communication is at the heart of this mood as well.

And what I always find amusing is that it can take a week to create a useful and important feature, and 30 seconds or less to demonstrate it. There's no justice in that!
