*heheh*

Indeed couldn't resist it, (the title... :roll: )

Okay... after a few talks and chats with people whom bought a GVP Jaws or Jaws II and as we all know getting the memory SIMMS is not only next to impossible, it is also damn expensive!!!

well in this day and age this shouldn't be!! especially when one can buy the components at less that a 10th of the cost!!!

So I am appealing on behalf of GVP JAWS owners out there, if anyone could donate a 4MB or 16MB 64PIN GVP SIMM for me to... dismantle record the design and then rebuild it.

The process SHOULDN'T destroy the SIMM, however i cannot guarantee this, but, the data I gather will allow me to develop clone boards of the memory VERY cheaply, and of course the donor of the SIMM will get not only a replacement should the original be destroyed, but also another clone SIMM

I will also post the finding of this project on Aminet as well as on other forum sites, so if anyone is feeling generous just reply here :D

Re: Want to Dismantle :) GVP 64Pin 4MB or 16MB SIMM

Hrmph. I have two 4MB GVP SIMMs on my A1230 Turbo+ Series II, but I'm reluctant to part with one of them unless I can find a 16MB replacement... or better yet, two 16MB replacements! :LOL: If/when I do find the 16MB SIMM(s) I'll be more than happy to pass along a 4 mb module to you... :)

Re: Want to Dismantle :) GVP 64Pin 4MB or 16MB SIMM

I have eight 64pin simms..

P/N: 10021174 0A
PCBA. SIMM. 32MB DRAM WITH WHITE STRIPE

I do not know if these would be compatible - do you know Zetr0 :?: or would you like one to play with :)

Re: Want to Dismantle :) GVP 64Pin 4MB or 16MB SIMM

be aware people i can remember there were some 64pin simms that looked like GVP simms . They were not volt compatible though as they came for printers and stuff .. so i would try to tack down some information about imnogeek¨s simms before putting it in my acc ... But one can only hope they are compatible...

Re: Want to Dismantle :) GVP 64Pin 4MB or 16MB SIMM

@imnogeek

Hello there, thank you for replying to the thread.

From my research thus far the GVP cards only use 4 OR 16MB 64pin Custom SIMM's, these are not to be confused with Apples 64Pin varient as the pinout is completely different.

Coze has helped me out with some 4MB sticks to disassemble and re-build and in truth it wont hurt if you have one or two spare for comparison and perhaps conversion ? :)

all info is good info.

again thanks for your help. where about are you based?

Re: Want to Dismantle :) GVP 64Pin 4MB or 16MB SIMM

@Zetr0

since you are pretty skilled with electronic stuff have you noticed there's an schematic for using 4MB simms as 64pin GVP simms on Aminet? Perhaps with your electronics knowledge could find a way to convert 16MB simms into GVP ones.

Or perhaps you could build some kind of adaptor.

Maybe it would be possible to do 4 small cards with connections like GVP simms that include cables to a small board with a simm socket for a 16MB/64MB simm. A pair of jumpers could be used to activate 1,2,3 or the 4 virtual gvp simms (for GVP cards with only 2 or 3 gvp simm sockets).

Re: Want to Dismantle :) GVP 64Pin 4MB or 16MB SIMM

@Crumb

hello there, first let me thank you for kind words :)

I have reviewed the files on Aminet that you link to, infact I have a huge A2 prinout of whats in the package, however its missing some inportant information that I could use.

I looked into making a 72pin SIMM adapter, unfortauntely there is not enough room to make one fit inside a desktop model A1200, perhaps A2000 upgrade though.

My plan is simple thought.. research, revise and then re-implement. my hope is to get SIMM boards manufactured very cheaply and have a lot of them made, say atleast 100, and then populate them with chips and sundry and sell them on for cost :)

I plan to re-use memory chips from 72pin SIMMs both 4 and 16mb to keep costs at an absolute LOW

if you want a stock of chips I have a silly amount of 72 pin simms which are at your disposal, FOC :)

You need to get to know us better; most of us have UBER amounts of various types of memory in our stocks / junkpiles / whatever...... :mrgreen:

I have two old sticks of 166-pin PC-66 memory from a Compaq Armada 4000 series laptop, they are about the right era and memory speed for Miggy applications, but I can't find anything out about the pinouts, could you help me out here? The Compaq part number is 218071-001 if that helps.

This part no. shows 16mb (2 x 8mb) 70ns non parity, not sure on pin outs but the chip no. may help

most of us have UBER amounts of various types of memory in our stocks
I was thinking more for the project mentioned where a stock of the same chip may help eg...

IBM B1D13600A 4mb EDO (1mb x 36) with 12 chips on each, Qty 36 = 432 identical chips

@Zetr0

Do you have any detailed specs of a GVP 4mb and if so can you let me know please?
Thanks

Re: Want to Dismantle :) GVP 64Pin 4MB or 16MB SIMM

@imnogeek

not yet.... but I WILL :LOL:

and when I do, I will post these details far and wide..... and also on Aminet LOL....

I will then put up a complete pinout datagram, and I think from this it should be possible to work out the 16mb version (we shall see)

to which I will also post, with complete eagle files to make your own, or atleast have the PCB's made for you on the cheap.

Hopefully, it would be nice to see the difference of the Apple 64pin standard and the GVP 64pin standard see if its possible to convert these with out to much fuss....

Re: Want to Dismantle :) GVP 64Pin 4MB or 16MB SIMM

Unfortunately University is whipping my a$$ at the moment, being the roll-on year for my MSc theres a ton of work,

My hope is to get a weekend soon :)... oh... that would be nice.....


heres the main reason why my time is so eaten up...

I get up at 04:30am make breakfast for me and wifie, cycle into town for 06:00 (its a few miles from my house)

get the 06:15 bus to the city, get off the bus at 08:15 get the next bus to University get at univeristy at 08:45 lectures start at 09:00

now I get home on average 18:30 - 19:30 pending on traffic and any extra work I may of put in... last Thursday I got home at 20:15... that was a looong day.... you know its a good thing i suffer insomnia LOL i would never be able to get the time to fit it all in LOL.

anyway I do the above 4-5 days a week pending on group seminars etc.

I think worse thing of it all, is that I have my work area preped and ready for much hackery... but it sits there in its little pool of light without any time for me to do anything... sigh.... a weekend soon.... must have one :)

Re: Want to Dismantle :) GVP 64Pin 4MB or 16MB SIMM

@ZetrO: do you still need GVP simms? I have a couple, and since i also have Blizzard cards (which accept more memories), i could donate you GVP simms for you to futher investigation if that helps in any way

If you are interested, let me know please, send me a PM with you address and i will send you the simms

Cheers

Sebastian
