It is available in a PLCC package which makes it easier to accommodate on a smaller board - it was used in the Atari ST machines so there is a fair bit of old stock around.
That sounds better than DIL and would allow a solution without PLD - probably an advantage for tinkerers. The driver changes to initialize and use this chip has to be compared with the driver changes to get rid of highres timer dependencies - hard to say what costs more time.Pr0f wrote:It is available in a PLCC package which makes it easier to accommodate on a smaller board - it was used in the Atari ST machines so there is a fair bit of old stock around.
Maybe Dave or Derek can answer this. From the routing issues involved, I think it's likely that the outer board is not flipped by the mini backplane.Pr0f wrote:does the mini backplane flip the top board that comes out from the QL - I know it flips the board that would be entirely within the case?
HI Dave,Dave wrote:The upper out facing port is usable with lower profile cards like the SQB, but no with the SGC etc. The in facing port is inverted.
I have none of these left but can whip up a batch if there’s enough interest.
I do like the idea of a Q68 compatible Ethernet card.
Could the VSYNC signal be used as a fast timer?
