Grandstand 6000 - ADMAN 1978

Post by CMcDougall » Wed Apr 25, 2018 10:05 pm

Got my first ever 'games' console out again, as sure it was colour BITD not black & white per yesterday :(

outside
this was bought for me 5th December 1978, still have original box & the receipt for £23.90 !!
newest chip is dated 1978 wk34.

anyways, since I have lots of 'new' capacitors loose in a bag, thought would change them out to confirm if was colour.

firstly, after a bit of research, BITD printers / manufacturers could not print the 'u' on them, so instead most still had 'mFD' printed :shock:

inside
back 3 = 100uF 10v, 220uF 16v, 30uF 10v & front 2.2uF 16v

i did not have a 30uF to hand, so will do it may be in another 40 years time....... :o

good news, it back to colour :mrgreen:

noticed on new TVs, with auto tune, it found four of its channels on Analogue. 3rd one it found is best.

I wonder what the 28pin chip is, it says "AY - 3 - 8610" ,
does anyone know if I read this into my beeb by anychance, or will it cook it? :?:
must be an early 4k (2732) or even a 2k (2716) or 1k (2708?)?

No Col, deffo don’t plug it into a Beeb rom socket, it isn’t a memory device, it’s a bespoke game-on-a-chip and you’d probably bust it!

^cheers Martin, just been away for a quick google, and yes seems only goes to the RF input box to make TV signals.

so the 'GI' company must of been the pioneers of the 1970s decade.

also, seems they only go for £5 unboxed, and £36 tops with all the original stuff like mine minted.
..... goes to work again tomorrow, flip! #-o

So did replacing the capacitors get the colour back?

If so =D>

£141.56 !!!

That thing was £141.56 in today's money. You ought to be soldering that back together with gold.


I can't believe there's been this much inflation only in that space of time. But there it is: http://www.thisismoney.co.uk/money/bill ... -1900.html

Yep, I read that part but wasn't sure it was directly related to the capacitors or some other magic you did! :D

I've got our old Radiofin somewhere, doubt that's worth anything either ... :(
