16 bit Intel ABOVE memory board in XT computer

Yup, this is the response that I received for the BBS files:

Hi Chuck,

Unfortunately, JDR's BBS is no longer available. We have changed our
Entire Date Base last year and none of those old services are available.

Sorry for the inconvenience.

This is the board i mentioned earlier

$(KGrHqQOKokE3F!V(bN4BN7KIG!(eQ~~_12.JPG


I bought it, because else a other one does..

And i did first some research on it..
The advertisment said:

RamBank

MCT-EMS

Made By Modular Circiut Technology

Many older chips

RamBank Expansion Memory Board 8 Bit ISA Taiwan

Its a Taiwan board as the titel says..

So i tried to found out the manual / more information on stason.org.. And finding this one:

http://stason.org/TULARC/pc/memory-cards/MODULAR-CIRCUIT-TECHNOLOGY-Memory-MCT-EMS.html

and

http://museum.ttrk.ee/th99/i/M-O/51046.htm

and

http://jdelliott.org/wiki/index.php5?title=MCT-EMS

I did also search on google..

Found some infomation on
http://books.google.nl/books?id=C6V...q=MODULAR CIRCUIT TECHNOLOGY MCT-EMS&f=false

The price was 129,95 USD for this board..in the time of release / when it was available on the store.

Only had to need a driver for it.. Because of the help of chuckG (thanks) i found a driver, that should be for this board.

If found it also here:

Now waiting if the card arrives and the drivers working.. Then iam a very glad vintage computer user..

Thanks anyone for the help.

Iam a little bit further on this problem.. I tried those drivers out for the MCT_EMS board but can get them work..

It seems, the board is the same as: DFI MEMO-2000X EMS board.. But MCT had sold it on his own name.. But the drivers that i had found on the JDR site are buggy..

Now my question is.. Does anybody having the drivers for the DFI MEMO-2000X EMS board.. Then iam trying does out and hope it would be a hassle free installation this time.

hello
Chuck do you know my version (you can see a picture at the -> Thread: "Intel Above Board 8-bit Drivers" )
...I think it can manage more memory then the DIP chip versions (?) :)

...and indeed it do! from auction no 190744478143, I can see the version I have can handle 32 Mbyte RAM . Well I still am short of the driver....:huh:
/cimonvg
*edit(again): my card is labed "INTEL classic" do have SIMM, but not the same card as above mentioned.

Just opened a tread on this...do you know of a generic DIP SHUNT that would work on this boards?
...Have my eye on one but without the DIP SHUNT would be useless in my XT.
 
Thanks HAL, et all!
This is awesome, we know have a far clearer idea of what are some of the DIP SHUNT options at hand for anyone willing to opting to install these cards in an 8 bit bus yet missing such a critical piece.

I know this is a very late reply to this thread (8 years likely not the record) apologies if it’s covered anywhere else - if so please signpost me! I’m going to be buying an Intel Above board to hopefully be used in an XT 5160 alongside an Inboard 386/pc. You’ve already guessed it the dip shunt is missing and long forgotten. If I opt for one of the above options are the switches actually set to a value to bridge the connector in some way. Those digikey options look to have dip switches embedded. If so could someone possibly share the switch order eg on / off / on etc.. or am I missing the point of it? I suspect there is some bridging in some way if not all the pins.

I know a number of forum members on this thread are still active (all being well) you don’t ever really leave the hobby like this..

Thanks in advance Mike

same here, I looked around trying to find that chip in the intel above board 8 plus I/O and from some photos online it seems it's just this one with everything set to on (if you are using the dip switches one) https://www.ebay.com/itm/124319525148
I could be wrong but this post seems to confirm that https://forum.vcfed.org/index.php?threads/intel-above-board-14-pin-dip-shunt.49937/
 
Thanks Saif I guess it will be a voyage of discovery. Looking at NC_Mike’s picture it looks to be a straight shunt across the pins. I did message Mike also to ask and the other posts confirm it. If you get to try this with your card do let me know I likewise will update when I try it as yet I don’t have the chip so will likely need to order or make one..

I'm still running one in an XT clone. No problems, although there's something tickling in the back of my skull that says a V20 is necessary--but that could be only for a related application. Too long, too long...

Hey @Chuck(G)

It’s time for me to get one of those chips ordered then, so can you confirm it’s a straight bridge chip for u111 to swap to 8bit ?

Eg:
IMG_8600.jpeg
Pins have a connection between
1 to 14
2 to 13
3 to 12 etc…

Assuming it’s straight across

Thanks in advance!

Mike
