Which RAM Upgrade to you suggest

Post by leon22 » Thu Jan 10, 2019 6:37 pm

Hi!


Is it better to use the STF/M 4MB SIMM - C070789 [0020] Upgrade in combination with Booster 2.3
and STFM KIT DUAL TOS [0131] or 4MB MMU TYPE RAM UPGRADE [0035]?

-> my mainboard is an Atari STFM 1040 C070789 Rev.E!

Are there any differences at all or is it only a matter of how much work I want to invest?! ;-)


Thank you for your help!


Greets,
Peter

Ok, and how do you connect the 16MHz wire to the shifter IC? (it's not the original if
the RAM Kit is applied -> I found no information for this scenario in your Booster 2.3 explanation)

Or let's ask differently: where is Pin 39 of the Shifter IC on your replacement?!


Thank you!

Ah now I see: it's just an adapter for the original IC not a replacement!

Thank you for the quick reply!
