Hi,

I just aquired a BBC issue 3, with Opus Disc Drive board and external speaker connection:

There is a mod. to the board under the Opus board

Looks like pin 40 has been crushed...

I have look at the power supply to check or change the capacitors before power up.
Regards,

Derek

In addition to the above BBC issue 3, there these items included:

Quite nice system, once I check the power supply .

It was more like 2 days ago, but I received a Wong's Model B Issue 7. I tried livestreaming the unboxing but it was a bit of a fail, hence the grainy shot and weird pose.

This one's a resto project. Several keys are missing, a couple others are broken, and it gives the infamous Long Beep ... but it was a very good price (in the context of the Australian market) and it's nothing I probably can't fix.

I quite like the home-made air vents in the case, that's a good idea.

Interestingly, the vents appear to be right on top of the PSU. I've seen this mod before, which makes me wonder if there was a template somewhere (maybe in a magazine or user group newsletter?)

Whilst part of me would like to restore this machine to original condition, I'm leaning towards leaving the vent mod as-is. It's part of this machine's story, and the rest of the case is in quite good condition overall. (notwithstanding the black keyboard surround, which has a crease in it between the cassette motor and caps lock LEDs ... I wonder if something heavy was placed on this machine at some point? It'd explain the broken keys and the crease)

Could have been caused by a falling monitor...

Is the ZIF socket lever a bit skew-whiff as well?

How would you do that if you wanted to? Fill the holes with something? If so, what? Or replace the top with one from elsewhere? Where?

Oops. Well, it'll be useful in porting the latest OpenSSH to SunOS 4.1.4. A bit faster than the SPARCstation 5.

Nice pizza box Stephen!

They do come up occasionally for reasonable prices. I scored an IPX with keyboard and Sun monitor for postage as the owner was moving house and wanted rid. It's ex Bath Uni Maths department. Just needed a battery hack for the NVROM and it's a good 'un. I was given an UltraSparc 5 by someone too, but I spoiled that by shelling out for a Ultra 10 case and more memory (£100, ouch).

I use my sun oracle T5000 spare server as part of my shelving system, I never start it as the noise is so loud you have to go to the other end of the house. Perhaps I should have bought a sparc Station instead ...

Now I have the sound meter from the 3D printer tests I should probably start it up and test it, if I can remember the ILO commands

Good luck with the Beeb. If it would help, I can send you the @, 6 and X keycaps from a scrap keyboard I have here. What else is broken on the keyboard?

Don't bother hacking the NVRAM, just buy an M48T02 from RS Components or Farnell.

Two problems with that idea:
1) Finding a M48T02 - out of production.
2) The M48T02 went through at least two revisions, and despite the specs not changing, "newer" versions wouldn't work when dropped in to IPXs.

The NVRAM on my IPX was my first attempt at dremeling off the cap. I damaged the 32.768kHz crystal and ended up with a 24 pin IC with two extra pins at each end. For the battery I initially used a tagged CR2032 that I had lying around (fell off and died during ~10yrs in storage, and have recently replaced it with a CR1220 battery in a holder hotglued to the top. (CR1220 chosen because it fitted in the smaller space and I had a spare one)

The UltraSparc5 uses a M48T59, which you may have more luck with a new replacement. On mine I dremeled off the battery and then soldered/hotglued a CR2032 battery holder onto the device. (CR2032 chosen because there's more space in a U5, and its a common PC CMOS battery)

If you want to go down the dremel route, I suggest buying a set of burrs. ("DURATOOL D00150 Diamond Tipped Burr Set, 30 Piece" was the kit I bought)

Possibly. The ZIF socket lever seems fine, though.

It'd be time consuming, but doable. I'd probably borrow the methods used by a couple of prominent YouTubers: The 8-Bit Guy made a video about filling a large hole in the top of a Bell and Howell (rebadged Apple II+), and RetroManCave made a video where he got a couple of Beebs resprayed. That said, I'm getting used to the vents; it's part of this machine's story.

That's a really kind offer, but I've managed to track down a parts Beeb (it's pretty ratty, might be beyond help). It's got some good parts on it, including a complete keyboard.

Thanks for the offer though ... it's this kind of thing that makes me appreciate Stardot (as well as the Acorn community as a whole). :D

I have seen about all the 8-16-32bit machines between 1980 and 1992
i can confirm that this A3010 is the best look, best OS, best basic, and fastest.

Really?... :-k :-s :-? :shock:

It funny to see how different we all are, for me the A3010 the only one I never wanna have because of his awful look... :(

Apart of this version:

I've not had any of these problems with sun3x/sun4c/sun4m machines. The M48T02s from RS just work in the sun4c as do the M48T08s in the sun4m machines.

True that the U5/U10 etc. NVRAMs are impossible to get though.

At some point I may be brave and take the motherboard out at which point I will have a look at the soldering to see if any of it is a bit less neat and tidy than the rest. Are there any tell tale signs of an upgrade?

Half the DRAM chips in sockets. Any maybe a different batch/date code.
The extra connectors not being the same type/style/make.
The extra chips having a significantly different date date code.
The cut-outs in the rear case for the extra connectors not being as neat as a production B model.

I love reading (or at least skimming!) the old computing books - it was all so exciting and FRESH in those days. Now all "intuitive" GUIs and "AI" etc.

Or am I just hitting peak nostalgia [-X
