Hi all,

I'm looking for an RM Nimbus PC, a working one, please!

For those who don't know what one is, here's a pic of one:

I live in the UK and don't mind picking it up.

Cheers

Re: WTB: RM Nimbus PC

I believe that I have at least one of those hidden at the back of my shed...

I'll have a rummage around tomorrow and let you know :)

Not sure if I have the original keyboard or not though, although I'm sure I have one that will work :)

Re: WTB: RM Nimbus PC

I'm sure I have the nimbus somewhere around, but I just can't find it!

I've found a mouse and a basic manual to go with the nimbus, but no idea where I've put the machine itself.

If I come across it I'll let you know.

Re: WTB: RM Nimbus PC

Wow last time I saw one of these I was still in school
just as a matter of interest what was the spec on this machine I remember using a program called mail box a primitive mailing software and it got me into a lot of trouble
these machines ran BBC basic and as the teacher removed all the games I decided to type a bbc game out it was snake just like the nokia version but in color and mailed it to everyone teacher was not impressed :D

Re: WTB: RM Nimbus PC

They had an Intel 80186 processor (probaly the only machine I knew that had one) and had 640k RAM.
No HDD (although later models had one) and they had a 720k floppy drive.

@woodycool

Bit OT but here goes, The BBC Master DOS 2nd processor carried an 80186 too.

Re: WTB: RM Nimbus PC

Re: WTB: RM Nimbus PC

That's why it was easy to port BBC basic to it
Thats what got me into trouble

Re: WTB: RM Nimbus PC

I've made some enquries at work (which may or may not be a certain two letter establishment) - apparantly these are like rocking horse poop and therefore there aren't any kicking around. You might get a bite by posting on one of the UK Education ICT forums - I'm sure I've seen the odd Nimbus floating around in a server room or two on my travels, you just need to find the Network Manager/Technician that's using it as a footrest!

HTH!
 
Re: FOUND: RM Nimbus PC

I've finally found one of these.
It works (it boots from the floppy disk) but I don't have the correct monitor cable/adaptor.
Does anyone know what the pinouts of the colour monitor connector (8-pin DIN) are?
 
Re: FOUND: RM Nimbus PC

@woody

I can't believe you found one working :shock:

Well done mate, I'll have a look around see If I can find the pinout. I'm pretty sure it's going to be TTL video levels though so we may have to go down the route of attenuation resistors for a regular scart or analogue monitor.

BTW -- Do you get the proper monitor with it ????

TC :D

Edit - Found this quote..

"The video output was either a BBC standard 5 pin DIN plug or a 9 pin Sub-D plug giving a CGA level output. The 286 and 386 versions had VGA 15 Pin Sub-D plugs instead."

So my guess is std CGA (TTL) pinout will apply :wink:
 
Re: FOUND: RM Nimbus PC

Are you sure it's a 8 pin DIN? I thought Nimbus PCs came with either 5 pin DIN (like the BBC) or 9 pin sub-D connectors; the output is CGA standard, if that helps.

Could you post a photo of the connector?

Edit: not quite quick enough on the draw - TC got there first!!
2nd Edit: 8 pin, not 9 - :Doh:
 
Re: FOUND: RM Nimbus PC

Shucks, 8 pin.....

@ TC

Do you think Woody might get this to display on an EGA monitor? If so, I may have one (an old IBM) in the loft.
 
Re: FOUND: RM Nimbus PC

@Merlin

Possibly

EGA is defined as Digital Input which is basically TTL levels for R-G-B and then a control signal for intensity....Analogue. The Line frequency may have been different though, can't remember this is all to long ago :LOL:
If he has a Beeb style 5pin socket then this can be configured to work with any 15Khz screen by the use of some clever limiting resistor's ala Beeb.

Truthfully anything can be hacked to work one way or another :twisted:
Lets see if woodycool has the original monitor first...

TC :wink:
