Blizz 1220 4 mb Simm hack...

B1220+4M.lha

Anyone here know of a better DIY then the one on aminet ?
I can't make heads or tails using that. Maybe some one here can explain it a bit ? (Not to tecnical please. I do know how to solder just not how to understand that description)

I don't think it is worth the trouble, as 020 "accelerators" for the A1200 with simm sockets that accept 8 MB, or even EC030 M-Tecs are dirt cheap this days -> 10-20 EUR. I rather look for the original 4 MB Expansioncard as a collectoritem. If anyone has one to sell I'd be interested. I'd take an attached B1220 too someone does not want to sell it seperately

It's worth the trouble if anyone know a better description. I have lots of 4 mb simms laying around and i have a 1220 in one of my two 1200. I got the 1200 for free and don't want to spend any money on it right now. I will just use it as a Game machine with WHDLoad. (wich i registerd some days ago  :-D )
But 4 Mb fast is just enough to run most games. 4 Mb more would be ultimate.

Yes.

Look at the _4MEGA_0 pic, it's a 'simple' pin->pin wiring job.
The numbers in blue underneath the gold SIMM contacts show what pin it has to goto on the 1220 expansion header.

eg. SIMM pin1 ->Pin30,Row A
      SIMM pin2 ->Pin27,Row B etc.

Yes! Thats it :-D
Thank you very much.
Is the pins on the Simm the same on both sides ?
