Hi, there is a Sharp PC-7000 restoration video in YouTube from Tech Tangents () where he is talking about a solution to connect a HD but there was no progress so far.
But in his video you can see the original video adapter.
Maybe he can help to get more informations about the upgrade video card.
Hi, are you gone sell these ram modules?
I have one SLT 286 and one SLT 386 and i'm looking for ram upgrades.
On the 286 i have one 1MB module and on the 386 i have one 2MB module.
