TT030 System Board Images

[dexterslab]

here's two images of two TT system boards, the one is a much earlier design, very few SMD. Both are 32mhz models. It's surprising how many patch wires there are on the later board though, you'd think the atari corp engineers would get better with time!! I can't see any revision marks on either of them.

If anyone else has some images of other versions maybe you could post them up too?

Very nice pictures.
Is that a SLR you are using?

[dexterslab]

no, just a cheap canon compact, i keep my nikon slr for proper photos

My TT motherboard.


TT-ram


Tried to attach, but just hang there... so when back to imageshack.

[dexterslab]

neat, which st-ram board is that?

[wongck]

The ST-ram board is on the same side and just above as the dips switch.
You se 2 rows of 8 dram chips - that's the 2MB extra. The other 2 MB is located on the motherboard itself beneath the st-ram board.

yea, reason i ask is it's different from both of mine. I think some are easily upgradeable to 8mb

[wongck]

It's an original Atari part. I seen somewhere that they are upgradeable by just replacing the drams.
But I have not really checked on mine. I think 4MB+32MB is plenty for an Atari.

An early one that I am cleaning up at the moment. Possibly revision B with a 32Mhz Daughter Board fitted by Atari to "cludge" up to 32MHz from orginial spec of 6Mhz. From a knitting factory believe it or not!!

[wongck]

Yeap.
Looking more similar to the one circa 1990 in OP.

yes the top one of the topic is a rev k-j
has the vme fix and also the clock fix so is a rev H board
most are rev h with various fixes
ive seen my own rev h has none of the revj-k fixes
frank lukas sent me five board and a scrap
two are rev J with the wires
so im plodding through repairing the boards
however both have halted mpu so i need atleast one 030 32mhz ic
no good!!!

ill add a doc as it seems my trails around all the sites show no service docs for later board fixes
in wires
ill take some photos and show the wires and where they go
in schematic form however if we can find a later than rev B schematic

for h -jk conversions
best is holding out becouse prob knowone bought it from him schematic for rev J would be an orgasim for sure
i think this is a needed mos for h- j-k
like me

ill stick on some cash if some people want to go share
for the schematics for rev j
share on a board fund basis

if it takes payin a couple of homboys to go around
then so be it...

above all the TT is a more rare machine than a bog standard falcon
there is only two revisions to a falcon and they only involve production critera changes with the pcb and method
{watch for rev a or b combel}
but with TT watch for REV a-b mcu as they carry the same details
but inside are not the same

its cheeper to buy a 2mb riser card on ebay and take its mcu off
than buy a known good one!!!
or so from best..!

in all honesty i wish i had my own with daughter card pga rev b and add all the fixes
then again the later rev j-k kicks ass...

a rapid share to all docs i collected

Close up on that "Atari 32 MEG DAUGHTER BOARD / PGA" baby.



Surely the possibilities for hacking are in abundance? What are the mods I should do for this board revision?

Also, has anyone ever thought about using a 040 or 060??? I assume that Atari left this off do to cost, availability and as they would ideally have a 'range' of branded machines at various capacities. For example they wanted a 030 and 040 Falcon model, and the 040 was to be the top of the line workstation.

So what do I have to do to sort this out? For a fact, I think I am going to have to put some heatsinks on the U3 and U2 as they are uncomfortably hot in use, and this is worrying. I have not yet had time to read up what they are for.

Once I am done with the heatsinks (can anyone recommended any?) I bet there is some serious overclocking potential here on this hotrod! ... I think we should let Falcon owners know what they are missing out on!!!
