Looks like this IC is a direct replacement for TMM2063

Will be looking into that board again soon . I know it takes RCM a long while - but we`re always SO busy with SO much to do! :D

GENERAL RETRO CHIT CHAT / Making the most of the iPlayer
« Last post by MiniMort on March 15, 2017, 08:08:43 PM »
So I've just been on the BBC iPlayer to catch up on the Real Marigold Hotel but when I typed in 'Ma' the series popped up 'Making The Most Of The Micro'. I don't know if it's only on iPlayer or if they're airing them on BBC4 but the episode I saw is in really good quality considering it was on TV in 1983!

HARDWARE/SYSTEMS DISCUSSION / Re: Commodore Amiga Keyboard Membranes

It might have been a while since this topic was started, but now that AmigaKit has run out of the NOS A1200 keyboards, we can now supply A1200 keyboard membranes (as well as the A500 and A600):

GENERAL RETRO CHIT CHAT / Atari Inc. - Business Is Fun (Book)
« Last post by Gary6581 on March 15, 2017, 12:31:40 AM »
I downloaded a sample via Kindle after seeing a post on Facebook,thought it was interesting, so am now abouthalfway through the full book.

Just wondering if anyone else has read / is reading it, and what your thoughts are?

Not being born until 1982 (I often think I was born about 15-20 years too late, given my interests!), most of it is a little 'before my time', but I'm enjoying reading nonetheless.

ARCADE / Re: I dun got me a Q*bert!
« Last post by WW2GURU on March 15, 2017, 12:00:12 AM »
A slim chance you'll see this but this is the only place I've found that has a picture of this board. Could you tell me the values of the 2 large resistor bars by the 44 pin connector. Someone removed mine before I owned it. Can't go into game mode :(
Thanks in advance

Rokay - will eventually put up a repair log as the sound system doesnt work, havent fitted the control lines to my harness yet so I cant confirm if it plays or not, but... here she is....



Its probably a bootleg, although it could have been a licensed board, its looks rather well made for a bootleg, but the pinout is not the original Qbert and the original is slightly harder to JAMMAify as you need to build a circuit to take the separate horizontal and vertical sync to make composite sync, thankfully this board already outputs csync.



One 8086 CPU, rarely seen in arcadia, probably coz it was so expensive, the majority of early boards are Z80 based.



Very old RAM chips, 64 x 9 bit capacity, that's bit not even kb!! You can see where the battery used to be in the top right corner, lots of corrosion, lots of tracks rotten through, the SRAM is probably the sound RAM and there is almost certainly a whole world of rotten tracks under the top chip. Hopefully the chip itself is OK.



© 1979 AMD!! Tho this board is almost certainly from 1982 or early 1983 - which makes it older than my wife!!

So a basic harness was made for it, comprising 5V, -5V, Ground and the 4 video signals and power applied, I was expecting the worst, what I wasn't expecting was this...



I need to ground a pin on the edge connector to put the game into game mode, but when I did the colours were all wrong, the background was orange, Qbert was blue etc etc. Went back to the test mode and fired up the colour test..



Turns out the pinout online for the 44 pin Qbert is wrong when it comes to the RGB channels so a quick swap around fixed that, regrounded the "run" pin and...





 :D

Would love to build a replica orange cab for this game, I have the screen, not sure its something I would ever get round to doing tho.

GENERAL RETRO CHIT CHAT / Nostalgia Nerd (YouTube Channel)

Greetings.

Just wondering how many of you are familiar with Nostalgia Nerd on YouTube?

I don't spend a great deal of time hunting or browsing for retro system / company vids, but this chap usually produces decent stuff, especially if you're after a bit of historical context on top of actual system details

http://www.youtube.com/user/nostalgianerdvideos

Worth a look if you haven't already.
