BTW: I've still got one - fully loaded - Acculogic RAMpAT! card collecting dust here.
It expands any 286 to the maximum possible 16 MB RAM. It's loaded with 4x Siemens 4MB SIMMs 70ns, configures itself automatically (single boot from an included disk is required) and is highly compatible - can even be used as EMS. I've sold quite a few of these in early 90's and they were the best. The card is in excellent shape. This one came back to me when I replaced the mainboard with a 486 one.
It comes in the original box (a bit beaten up), disks (3.5" & 5.25") and manual. Photos on request.
If you're interested make an offer, hardware preferred.
