Is A2091 compatible with 80pin or 68 pin with proper adapter ?

[lazyeye]

so as the topic says if i had the proper adapter could i use the 2091 with 68 or 80 pin scsi drives?

my A2091 has the 6.6 rom revision wich i know is limited to 1 gb drive sizes, am trying to get guru rom or 7.0 rom, if i understand what i read right the 7.0 allows upto 4gb drives but guru rom can use drives larger then 4gb, if that is true what is the ceiling for the a2091 with guru rom ?

also has anyone had success using a 4.3 to 4.5GB 68pin scsi drive with adapter on the A2091 v7.0 Roms ?  Reason i ask is i found a place that has either 68 or 80pin drive in the 4.3 to 4.5gb range for cheap if they will not work i would have to get 2.1gb from them

i also read about the pro file system, if i had that that would it remove the limit of partition size and drive size ? of course saying i got the hardware to support big drives :-D

Maybe. You will be trying to run 16bit wide drives on an 8bit bus (should be ok, the spec allows it). Ensure that the SCA (80pin) adapters are decent, not the cheap crap one finds on ebay.

HMM, actually, given what you are trying the cheap ones might just be fine; the above advice is standard when using on an U2+ chain. But do see f you can get decent 50-68pin adapters, preferably ones which terminate the high byte.

Also, I'd advise having an 8bit narrow device as the last device on the chain, and a good active termintor at the very end.

Vs the ROMs, I got so confused with which version of what ROM supports what partition size, I gave up. I must did my A4K out and get it up and running again though.
