While I did expect DEC-anything would attract more interest, I was figuring
people would have read my message from earlier in the day, here's the
extract/backgrounder:
So my house sold yesterday after < 3 days on the market (the market
here is nuts).
I have about two months to move, so a bunch of stuff has to disappear.
Location is the Vancouver, BC, Canada region (Port Moody more
precisely).
Most of this stuff is larger and I'm not going to have a lot of time to
pack & ship, so local pickup is expected.
If there is competition for something I guess it goes to the one
willing to offer the greater number of bucks,
otherwise items are free as the alternative destination is
recycling/scrap.
Any bucks involved are not because I expect a lot (or anything), but
just to sort out who 'values' it the most
if there is multiple interest in an item.
I reserve the right to be whimsical in any decision.
At this point three (distant) parties have inquired about this item.
No, I don't want to scrap it, but I can't make promises for shipping something
this size at this time.
If someone is "really interested" (you have the other bits for example), let me
know.
Shipping just the CPU board may be another option.
(There has been no interest in all the other stuff at this point except the
TRS-80 M100 and a question about the XT-clone.)
