Agree here. I loved the 68K and have fond memories of writing programs in
it. But

Look at the segment:offset architecture of the 8086 and of course it's single
interrupt (without the separate interrupt controller chip) vs the 68000
somewhat orthogonal 32 bit archi
cking faster
than the 6809.

➢ That said, you'd think that DMA would make a 1:1 interleave controller much
more feasible. And Bjoren also mentioned

Perhaps his son? Or the guy returned to DEC, or listed his career
differently on LinkedIn for other reasons? It's not a common name.

Maybe a different guy, since Pro development was in the late 1970s to early

Probably. Still would be interesting to see what the board actually
is/does, I wondered why they never did DMA transfers for the Pro, maybe
being a single user system it was pretty much pointless

Hello Retronians,
I just saw some interesting DEC Professional items on eBay from
smhelectronics261 (https://www.ebay.com/sch/smhelectronics261/m.html):
1. Pro-350 (and presumably -325) video board
https://www.ebay.com/itm/294933607768
2. RD (hard disk) controller https://www.ebay.com/itm/2
