Card info wanted

[John Le Febvre <John@klatch.demon.co.uk>]

Hi folks.

Picked up a bunch of Apple II interface cards at the weekend (28!)
a few of which I'm not familiar with.  Can anyone help me out?

Apple II interface cards

Manufacturer   Description                            Connectors
------------   -----------                            ----------
Apple          Graphics Tablet i/f                    PB6 & PB5
               Is this of any use without the tablet?

Apple          I/O Controller x 2                     D19
               Disk controller?

Apple          IEEE-488 i/f                           IDC26
CCS            7490 GPIB IEEE-488 i/f                 IDC26
               I know what they are, but does anyone
               know of anything useful to do with them?

Microvitec     No model/make marked on card           PB8
               RGB card?  This is a UK company.

Tecmar Inc     AD 211 x 2                             IDC50
               50 way = SCSI ???


Also 3 ROMs in plastic packaging

341-0036       (c) Apple '79
342-0077A      (c) Apple '78-'86, (c) Microsoft '77
AE RamKeeper 1.6


As well as that little lot, there was a II+ console, 2 disk II's
and a DuoDisk unit, but seemingly without it's controller.  What
does a DuoDisk controller look like?

Thanks in advance,
