Anything on the flip side?

It looks like a PCChips m507.

Note that there's no L2 cache on it. If you want the best performance out of that board, you should buy a compatible COAST module

not really - otherwise id have shown pic on both sides
theres a number 9546-16

after searching for "coast module" on google i got a link back to another vogons thread:
New Socket 7 Build

seems to be the exact same motherboard i have! with some slight differences.. but alot more similiarities then differences

it does say v1.1 on the board so i guess this means its a PCChips m507 v1.1 ?

https://web.archive.org/web/20030223182645/ht … cchips/m525.htm

hmm ok that board seems to have 4 pci + 3 isa.. + 1 dimm slott so that cant be right

its still very similar despite those differences maybe its an diff revision?

the m520 seems closer..

but still has 1dimm slot so no

ok maybe this is it.. PCChips m519 v1.1

still some differences with the IDE ports.. so its not a exact match - so its not this oen..

https://web.archive.org/web/20160808091248/ht … cchips/m507.htm
ok this might be it i think.. because it has the printer port next to the ide ports !!!!

http://www.motherboard.cz/mb/amptron/pm-7600.htm
this looks like a closer match too

I think you have found it. PC Chips M507 and Amptron 7600 are the same board. It was also branded as fugutech, pineview, etc.

the only thing i see is the absence of the keyboard bios on the drwing.. sucks that the web archive didnt pick up the image for that board
actually the m507 cant be right because it doesnt show the VRM either on the drawing.. could that be human error?
err wait - the other diagram i posted above does show the vrm..
https://web.archive.org/web/20160808091248/ht … cchips/m507.htm
confusing

so whats the best cpu for this board... will it take a p200 MMX? or does it need a regular p200?

any advice on what cpu to replace the p75 with?

I have 2 of these. IIRC the no vrm version tops out at 200mhz while the mmx cpu's require the vrm's split voltages. Both mine came with Cache sticks even. Mine are running P100's but a normal 166 or 200 would be a perfect fit.

Your board doesn't have VRM installed. The board in the drawing doesn't have VRM installed either. Without VRM you can choose:
1, K6-233 ANR (3.2V) or APR (3.3V), fast, cheap, common, might need BIOS update
2, Pentium 200, cheap and common, supports 1.5x multiplier, but no MMX
3, POD MMX 200, if you want MMX from genuine Intel, but rare and expensive
4, IDT Winchip, slow, cheap, common, not recommended

With VRM you can choose anything up to at least K6-2 with BIOS update.

i thought the VRM was that jumper block ting next to the cpu?
ok so as long as i get a p200 (without MMX and 1.5 multiplier) than i am good?
theres no COAST modules on ebay atm

VRM looks like this and it can be inserted into the jumper block.
Yes P200 should work out of the box.
Buying COAST is tricky because many sellers have no idea what they are so they just list them with genetic names such as computer cards, memory stick, etc. Same with VRM.

trying to find a case now that fits this motherboard.. as its just sitting on my desk
its about the size of a peice of paper 8.5 x 11" so i think its a BABY AT form factor?
cant seem to find any vintage AT towers for sale in Canada

You should be able to mount it in most early ATX cases. There are usually mounting points for AT and ATX in available.

what year is early ATX?
1997?
i kind of either want to do this "Right"
and make it look like a proper pentium 133Mhz or 166mhz (its got a pentium 75mhz right now)
hopefully with a little LCD readout that can be configured to display the mhz..
ike one would have looked in 1995.. either a tower or a desktop
any links to cases for sale are very greatly appreciated!
