Looks like a surveillance device from a sci-fi episode...

Careful, don’t upset it, or it may fire an energy beam at you :lol:

With any luck, Dr Who and Sarah Jane will turn up any moment in Bessie for a bit of sonic action to make everything good again :lol:

... some BeebSID and ATOMSID boards :D

My first experience of ordering from PCBWay!
IMG_4744.jpeg
Arrived just in time for me to get on a plane for a business trip abroad :?

I'll make up a couple of boards before I offer them to other forum members (I am just wanting to cover manufacturing cost and postage, not for profit)


Hopefully I'll report back in a couple of weeks and bring them to the Cambridge event.

Best wishes

Andy

Here’s a video to show how good X68000 Street Fighter 2 sounds :)

NICE :-)

I have a Yamaha MU10 hooked up to my main PC (Does Roland GS, Yamaha XG and standard Midi 1/2) and I have a Yamaha PSS233 in storage :-)

I really should get around to converting more BBC Music to Midi, I did Cold Tea & Disk user ages ago then never did any more :-)
Been around I.T. since the Beeb was born, maybe you've seen me around :D

I used this way back in the day to learn all about electronics. :D
IMAG1769.jpg

My father bought it to help him repair things electric around the house. I just liked it for the radio circuits;
IMAG1768.jpg

When my father died I had the contract to clear out his shed and I rediscovered the book lying unloved and mouldy in a pile of junk on the floor of his shed. It really was unreadable. :( Since then I had been looking on and off for a copy of it and managed to track one down recently.

Now for a good, nostalgic read. :lol:

An Acorn Atom. This belonged to a man that was great with electronics as well as engineering.

The Disc Pack seems to need some TLC and the Atom currently does not work. I'll change the socket of IC31 and see if that improves things. It is fully expanded memory wise, I just removed some of the video memory in the process of fault finding.

Current symptoms: starts with the usual screen of random characters, Break has no effect. Applying pressure to IC31 produces all kinds of graphical effects which do not include the "ACORN ATOM" prompt.

The PSU is a beautiful hand made cube and works perfectly.

The disc pack has it's power lead cut off, which is a bit of a worry. If the pack PSU would have deemed been beyond repair for this man it would be a challenge to fix.

There is a stack of floppy discs included and some tapes. I'll look into them later. The floppy discs could well be for different systems, the seller (son of the late owner) just assumed the might be for the Atom. They are only marked with numbers and the only index I found only referred to word processing activities. From the activities that the previous owner was engaged in they could also well have to do with systems control. I don't expect any games.

The ram/rom boards have batteries on them that don't seem to have leaked. The RTC is powered by two AA batteries that are also intact.

Very nice, good to know they are safe.
Are those boards known or have you also received a couple of reverse engineering projects ;)

Those are well known boards:

* A Big Benny real time clock
* A 16kB ram extension board
* A bank switching from board (schakelkaart)

Nice Atom btw😀

It may be the case that the mains lead was cut off to use on something else.

Apart from the transformer, everything else in the PSU should be replaceable. The only difficulty with the transformer may be finding an equivalent with the same electrical specification of the same format and size. But transformers are normally very reliable (unless severely overloaded).

I also tried to buy this one. However I am glad it came to a StarDotter :D

Do you known who the original owner was? Perhaps we know him....

I found a piece of “insulation” in the Atom that confirms this list nicely.

Well, I replaced the power lead and cleaned up the 5V power plug. It works fine. :D

My first idea was that perhaps the Atom was too power hungry for the PSU in the Disc Pack to cope with and that the home made power supply was intended to power the Atom as well as the Disc Pack. There was a led fitted in the 5V plug on the Disc Pack. But the disc drive needs 12V as well as 5V so that would probably not work. Bit odd. :?
