[Guest]

yipee the plugs arrived from the state's !!! sorting office too collect
lets hope they are right!!

[Guest]

the connectors are perfect
the mach210's i will order and pay for on tuesday done and sent for programming
they get sent direct to be programmed the test pcb is on its way
so all going well and i get some cheep ttl ill be rocking with a completed board in a week
two weeks later {10 days pcb turn around for 50}
ill start to have the first batch of 25 done

here is the costings and details too pre order one or more {first batch of 25}

Hello.
Im interested for a Magnum card, too
Simbo2, can you write me an PM ? - Im a new User and so I could not write you directly that time.

Thanks

[Guest]

you can email me direct if you like at vsmlibs@talktalk.net

[Guest]

if people pre order a board youll get it in the first batch of 25

also this helps me complete and pay for all the bits

this will be done anyway but takes longer as i need too pay my bills
and ill place i suppose something like 20 or 30 on ebay

100 simm sockets
£70 decent price but need more preorders to cover may add it too needed lump sum

not needed payed will arrive soon i hope
--------
its amazing the price dif between the vert and angled
some £1 and more per socket
terrible !!!
lucky we need the cheaper ones
70 quid for 100 this ia great !!! if i ordered 100 vertical
ordered and ill pay the guy in a week


done...!!!

[firyembers]

2 Units just prepaid,..

[Guest]

bits so far
the caps i have on a big roll

the simm sockets still too arrive , pcb and mach210's are still in production

[warp12]

I have a 16mb Atari board, with page mode simms. Not sure what specs those are.

What is the speed of this board in comparison, with EDO?

[Guest]

old 30 pin ram is no good
if you have a working ttram board and want more ttram sell your older ram

i think the 50 boards will make wont make a dent much in the tt ram market
only people with hungry ram setups will use tt ram so much
and others who want too load tos etc to fast ram and begin the track to the hungry user

edo and nibble modes have a common speed and what they do
you can use edo 128mb i do !!
the magnum is default burst
so will treat all dram as inserted as burst mode blocks

so edo is better if you get a source of edo 128 or even 64mb 72 pin 5Volts io and supply
ps 2 ram as fast page is plenty and fine fast fpm is plenty 60 or 50ns{rare} 5v i/o
you can even find new ram too spec


i see other boards that support burst mode some 20 % better but 75% less space {dont forget this stresses the chipset !!!!}
so perhaps this maker needs to share his sources to the common but i dont see his schematics or sources
so symmetric FPM or EDO like 32x32 etc
but must be 5v i/o this is essential too use other ram would need very major design reform
you need too look for 'server ram' at the time big companies had 128mb 72pin 5v edo 1995??? but most
low end builds used 3.3v {too roll it out see what happens with 3.3v and the old copper mine tech 10nm tech chips} atomic migration paramagnetic resonance
at least we get too use up to 256MB TT ram and load roms and resident and etc to fast ram post boot

so

do you want one or not .... ?

with jookies basically all rasp pie coming up this is the only project im doing and investing in

to get a holiday perhaps ????

i think the trick here is too look for a pair of 32 a pair of 64 and a pair of eventually 128

dont go for the big first

[Guest]

basically if people want ports added and changes made


tell me NOW

otherwise it goes to bed soon

ive not made the test board yet

its arrived but ive not populated it till next day or so

so....


now is your time.... and ill change it if needed

[Guest]

members should sell a known set of say 2 X 32MB etc if they have upgraded

HERE

then at least new comers have a pair of known to go with

for a few quid

[Cyprian]

Simbo,
can you do a memory test with Nembench? I'm curious about the difference between your board and standard Atari TT-RAM.
Here you can find Nembench figures for other TT's: http://www.atari-forum.com/viewtopic.php?f=27&t=17970

[Guest]

sorry i just dont have time do benchmarks

i think it will show in nembench around the same but more ram ,,, as is intended

[frank.lukas]

I think there are no differences with the Speed ...

[Guest]

what worries me is asking for benchmarks
this just stresses the chipset
and takes time has too many variables ie do we load tos to fast ram prg to fast ram
what o/s etc
dont see the point unless you know also what revision etc etc
na im not killing my tt board old man of the road
its like walking up and stabbing someone then start a stop watch
and see if they survive and how long it takes them to get back on there feet ???
ie can you all kill your machines a bit because im ' curious '
anyway...
looking at the posts in the thread this work has already been done in this post
http://www.atari-forum.com/viewtopic.ph ... 70#p211677
in the post it mentions that this board gave the best results

benchmark utils only give a relative output much like cars
a car comes off the production line
the next one might look the same but will be 100% different
so this is never a true test of performance
and like a car thats now some 20 odd years old
its getting a bit long in the tooth to drive round a race track over and over

[frank.lukas]

… here we go for a Speedtest ->

[Guest]

the point is there is 43 left out of 50 magnum TT boards being made

the more 20 quid preorders i get the less the weight on my wallet...

page 11 is where youll find this post http://www.atari-forum.com/viewtopic.ph ... 73#p248073

it has all the details about whats on order been ordered and arrived

as youll see over 90% of stuff has arrived

if you want one or two or more for a group order please post or pm or email

or follow the topic and prepay £20 per board {best way} and ill post you on the hall of fame pre pay guys this helps me
esp this time of year as i only start back to work now and end in november so im a bit skint

so far im on track for about 50 quid a board made up and tested and postage is included

so ive had to revise when stuff will be ready

as i am just waiting for programmed ic's and pcb now

the test board is mostly built now and ill test it at the weekend but this isnt an issue for me

)))))lol
ordering 50 boards will be and will cost like half a bag of sand {500 quid sterling not yer english money and £}
last time i checked the place of sterling was in scotland !!!!
so the english must join the pound sterling not the Scot's))))

all the bits except 10uf caps and programmed mach210's has arrived now for 50 units

i have about 100 VME type 3 row 32 pin connectors not right angle

if someone would like a couple to play around with the vme bus or tt ram or even one or two for the stram sockets

send me PM and ill post a couple limit is 4 per person or get your own from i believe warehouse 2 pallet 2 from best usa

[jok]

Payment sent for 2 unites. Best Jo

[Guest]

remember people its about so far 50 quid a board pre order is twenty
for instance today i sent £45 to wolfram for programming fees and pos customs fee tracking the mach210's
so this bit is on route
well done too the pre order guys its keeping it flowing
im confident too sell all 50 with members pre orders etc coming first
then an ebay sale as 50 quid a unit

anyway so far more than 10 are gone !!
so its 20 quid to preorder one
dont send postage the final price will defo be £50 per board inc post to you
£5 for every board goes to the forum
£5 mostly postage {some will take less some more so will even out}
cost to make per board is around £22-£25 all parts depends on exchange rate to make the 50 boards who knows i may get a better deal
just now its £420 sterling to get 50 as a 10 day or 20 day 4 layers gold plate very nice silk screen etc
one tester board cost me 81 euros as a 10 day service its populated fully
so i also decided to mount the TTL ics in low profile sockets and found them at a good price and its worth adding them
as you see there isny much in it for me other than making them up and a trip to largs with the profits ,.,,

best this is transparent in process then you can 'see' how much it all costs and there is no illusions
i now have ALL parts except mach210's {not arrived to program yet ??? perhaps a problem lets see }and 10uf elec caps {arrive tomorrow or monday}
then i have all the parts test board is aok so far with my controller from my own mach210 magnum it works with a pair of 32 MB and a pair of 128MB edo 5v io
great

so this is good news
so ill scrape beg borrow or steel to get 500 euros for 50 boards now
dont worry this is done i have half {£250} and will borrow the rest

[Guest]

The programmed mach210's are on there way

the test board i built worked fine
so ive placed the order for 50 boards {10 to 20 days they are with me}
five days to fab 25 boards , test , and we are done!!

[Guest]

so i go to check on the price for 50 board and its gone up 100 euros
so the design is aok
i need to fab as cheep as pos in a month time scale 20 working days or so
50 boards
who has a decent maker from cadcam for 50 boards 4 layers 35um copper all layers is ok { i can take the scrap fab boards also for a second run of no more than 25}
so far they are up to 579 euros for 50 11 euros each { a tenner give or take }
too much i want them for like a 5 er each i used this one http://www.wedirekt.de/index.php/pcb/2
quite good but no cigar...

surly i can fab them in china for far less and prob better quality
i want gold nickel .5mm tools .6mm tracks 4 layers 1.6mm board top screen only resist top btm

so if you have a fab you use that does
spec:
12cm by 5.5 cm 4 layer cheaper than 500 quid then"the jobs a better an.,. "

however so far in the stinking uk {England mainly even Ireland }
its costing like 2 grand for 50 and the cheek to charge VAT
the same quality as the german ones ...
and they are not now cheep !!! over my limit of 500 euros a quarter the price anyway ....
last week it was 458 euros {just within but no cigar}

the Spanish were a grand euro... inc tax post etc

the English need to get real no wonder they drag the Scots down the plug hole
my limit is like 300 quid for 50 4 layers i want to get as close to that as pos

if you can help let me know china 30 days is cool or even china 60 days service
as long as we all save a bit uk 2 grand eek where in the uk ?? mostly England SE
perhaps we need in Glasgow to invest in a pcb making spread instillation to fab pcb

i will endeavor to deal with a company ive used before in china mainland

[Guest]

well the mach210 cpld arrived programmed today from germany
so just pcb lot of 50 to order and wait on then a 2 or 3 day fab of 25 3-5 days post
so everything is back inline
if someone knows a good china maker for a cheep price let me know by pm
so far ive got it down to around 440 euros £400 or so for 50 boards + overun for 25% cost
perhaps 20 -25 boards are spare at production of a sheet or two will do for the next batch if needed

[Guest]

if you ever need a mach210 programmed see wolfram what a nice guy
he even put some nice stickers on the chips for us

excellent you see this is why i see the experts
when i cant program a chip family
i can do gal and pal eproms eeproms any pic etc... 130,000 ic;s just not mach types
one of the good guys
nice touch the labels check it out!!!
as i said 100ns ic's so will be vfast to support fast 60ns edo 5V io and supply dram
if you get looking for dram now
for 64 and 32 MB you find many more of these than 128MB
best get a pair of 64 or 32 that work
then look for a pair of 128MB when you need more ram
you can place a forsale wanted for this and sell a pair of say 32MB to another member as a good known to work type
why reach for 256MB till you find a good pair
took me three attempts and i found edo 5v io and supply
i have a pair of 16MB spare
and four pairs for level tests
the proto board worked as the same as the original

for 128MB and less the rules are FPM or EDO but must be 5v i/o and 5v supply {ps2 dram from a server .... ebay.com best bet}
so look or request the actual chip number type it to google and look for its datasheet.pdf
look at the type on the chip
chips are marked like a header .... then an ident like V or R or Q or C then a code as there size like ....C4096 etc
look for symmetrical dram simm config like 16X16 or 32X32 etc
you may need to also play with the jumpers
ill place the simm on board resistor config this usually tell the mach what type it is
sometimes you need to either change the simms resistors or blank out a pin on the simms
the best move is to alter the resistors on the simms board to tell the mach its a 128MB
as i say ill pub some info ive gleamed from some data sheets on a common 72pins simm config resistors layout {two bit +- gnd}

think the rule is fit some use it ? need more then = add it

[Guest]

waiting for pcb then the fun begins

had an issue with the simm sockets
resolved

so back on schedule

perhaps as little as 20 days to get the first batch built and sent out
