I know, I know, y'all gonna be like "What has this idiot got himself into now?..." ... Seems like I bought some junk off eBay.
So, I guess several things collided to make this thing come out like it did, One: I am kinda curious about 486SLC. Two: I love love love the tiny boards in this footprint Three: I was idly browsing eBay for something totally unrelated, and saw this listing by accident. Four: It happened to be ending in a few hours. Five: I got the impulse to throw on the minimum bid, fairly sure that some other bidding would ensue and it would get $15 or so higher, or that I would get sniped by a buck in the last minutes.
Thus, now I am the owner of two scruffy examples of this little bugger https://theretroweb.com/motherboards/s/pine-t … hnology-pt-319a though shipping might take a month plus.
They do not look all that bad actually, one had a Varta grenade on it, but it's grenaded rather than nuked, so doesn't look too hard to save. The other looks like it maybe only has minor problems. I think I can get my money's worth out of them one way or another, fixing up or pulling chips and sockets. I do have another similar board somewhere with an SX25 on, I would not mind if that got involved somehow, either upgraded with parts, or donating it's KBC or whatever. I have what I feel like is too many machines around the SX25 area, which need either perking up or liquidated. Another candidate is the janky AST Powerexec notebook that has too many flaws to be restored easily or cheaply to original appearance so might get a restomod with a color screen and a 486SLC.
Of course, just to get 486SLC chips, there was a seller Rose Electronics with them listed for under $10 NOS, but given that they appear to be located right where Helene made landfall, one might want to give it a couple of weeks to find out if they are alive, or to take a shrimping net down there and see if you can fish them out of the Gulf.
Edit: Just finding out that the highly similar but not identical PCChips M396F is a "no battery no POST" board, so that will be something to try.
EditII: Holy guacamole, there's a repro M396F board I could use all the chips on if the varta did it's worst. Re: PC CHIPS/FOXCON M396F ver. 2.6
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
