Picked up some cards

[gospodin@clubi.ie (Vincent Quinn)]

Just browsing through the local junk market the other day I spotted a box
with an original label reading Apple II Pascal - inside were parts of the
original Pascal package (manuals, leaflet, packing list and registration
form, but no disks) and - six interface cards. So here are the questions:

there are two Corvus Systems Apple Interfaces - one is revision J, the
other revision K1. 34-pin headers but no cables. I suppose these are Corvus
hard drive controller cards - am I correct? Can they be used for anything
else (for instance, will they act as universal drive controllers)?

an Aristocard parallel interface, manufactured in England by Simon
Computers. Printer cable attached. Works OK. There are four switches,
1-2-3-4: anyone know how these should be set for Epson emulation? As
currently set, 1 and 3 are on, 2 and 4 off.

a card marked VIA I/F CARD made by Glanmire Electronics. Two chips -
R6522-31 and 74LS74A, one capacitor, a 26-pin header. So I 'phoned
Glanmire, who are still around and based about four miles up the road from
me. I'm told it's a "general purpose interface card for electronic
equipment". Any suggestions what it could be used for? I'd like to try
setting up a home automation system - any info on this around?

finally, two cards the like of which I've never seen before. Just a four
inch x two inch black box mounted on a card; there are 19 connections from
the box to the card's interface with the slot (to card pins 1 to 9, 25, 26,
42 to 49). There is a stick-on label with the original owner's name and
"Place in Apple Slot 7". Screened on the card is U-NSCRUMP   MADE IN
ENGLAND   U-MICROCOMPUTERS LTD and the serial number - the first is no 01
(an attempt has been made to remove this, but still - ha! a collector's
item?), the second no 240. What on earth are they?

Thanks in advance for all responses
