Nice 8) . If you want the contents of the EPROM chip with the uncovered window not to decay, it's best to cover the window with either a paper label or black insulation tape.

Yeah I noticed that. I'm guessing that whatever is/was on it wasn't that important to the previous owner

A very nice boxed issue 4 beeb with all the leaflets and original guarantee (and an Acorn cassette player)! Not fully tested yet but boots up fine and all keys work.

I now have a boxed beeb for each of my kids once they are old enough. They *will* get into retro computers!

Glad it arrived intact.

I'll take this opportunity to raise a potential problem for AP5 kit units:

The 2 x 20 way connectors, for the User Ports, are new - old stock. I've noticed, when I've been building them, that the pins have become 'aged'. So I've been pre fluxing them and activating with my heat gun, before soldering. So I'm recommending something similar for kit builders. e.g. Check they're soldered correctly!

Thanks - Dave H :D

Actually, wouldn't an EPROM be OK in practice if it was inside a Beeb that was kept closed? I doubt much light would get in there!

Yes, if no, or very little light can get in, it does not matter. But it does depend on which case he has (different cases have different sized slots at the rear). And where it is kept. And this assumes the lid is fitted most of the time.

Thanks to a suggestion from prime I received some solder. Couldn't they have found a bigger box though?

I think this is probably as much solder as I will ever use!

Last week I was chuffed to receive this. The price was pretty reasonable, and I was expecting the green first edition. According to Elminster earlier in the thread, this is "much more rare", so I was pleased to receive the updated version!

The green first ed usually appears more often. I have both just in case, there was some useful extra stuff in the Orange one if memory serves me.

Got this from eBay - looked interesting. One of many beeb games I had never heard of.

At some point I may even get chance to see if it works!

Edit - tested and working although my Master only seems to be able to run the 40 track side. The 80 track side loads and then goes wierd with flickering colours on the top half of the screen.

Two GoTeks arrived a couple of weeks ago, also LED and OLED screens, switch and rotary switch soon after. The LED needed some resistors but soon all were set up as second drives on my Electrons' Plus 3 drives, replacing 3.5" HD drives.
They are powered from molex 3.5" splitters connected to the Plus 3 floppy drive connector.

Finally got bored of using T-Pieces to build up my Econet, and made up some boards that let me build the main bus out of RJ45 patch leads...

The boards from OSH Park:

Very nice! =D>

Reminiscent of these - http://www.beebmaster.co.uk/Econet/PBSockets.html, which I’d been wondering about copying.

Would you be prepared to share your pcb design on the OSHPark site? I’d like to build some of these for my growing Econet.

Nice idea, I did something similar (with only 2 sockets) viewtopic.php?f=41&t=5594&p=157254#p157254
My clock (based on the now "standard" Simon Inns design), also has an RJ-45 - viewtopic.php?f=3&t=11196&p=160889#p159071

My pin-out is based on the original Phil blundell design - http://www.beebmaster.co.uk/Econet/PBSockets.html

It looks like yours are using a different pin-out. I suspect it's unlikely you'll ever try and plug your boards into other RJ-45 Econet implementations.

But if people like this idea, can we agree a standard?

(I must get around to actually getting some t-piece replacement PCB's made - http://www.beebmaster.co.uk/Shows/Bolto ... 16-30.html)

It turns out I've managed to leave a ground pad isolated, despite having a ground plane across most of the board base, so not quite ready for sharing yet. I'll fix that at some point next week, and publish the design once I've has a set come back I know is correct. Given the size of the boards, it's only $16 for 3.

My Cat5 pinout is based on the published Econet wiring colour code for blue and orange, mapped to the Cat5 EIA-TIA568A scheme

Code: Select all

5-pin DIN number	Signal		  Colour					Cat 5 Pin
1						Data+			White/orange			3
4						Data–			Orange			  	 6
2						Ground			(other copper)  	 1,2,7,8
5						Clock–	     Blue				     4
3						Clock+	     White/blue			  5
