Hello Richard!
On Tue 06 Jan 1998 at 08:40 you wrote the following to All:

 RT> How does this "boot"?
Designed to put an EPROM in there, for diskless boot machines. It'll load a 
small OS off there, or something.
 WH>> That would be for the shared memory area, which this type of card

 RT> Shared with what please?
Transfer area for the network data. Rather than using an IO port, it can use 
a shared memory area. I think. May be wrong, because I don't know enough 
about PC hardware as I should...
 RT>> It has a network address sticker with 0000C0 7F1307
 WH>> Ethernet hardware address unique to this card by the sound of it.

Probably.

It seems you've got a RJ-45 connector for 10BaseT networking onboard, while 
the card has a BNC and an AUI.
Ah. Not easy, you could buy a protocol convertor to convert 10BaseT 
(RJ-45/phone connector) to 10Base2 (BNC/coax), but it would be cheaper to buy 
a combo network card for about 20 quid new.
You'd use a UTP crossover cable (not a straight patch cable) to connect the 
two machines - they're available from Maplin's, etc.
If you want to use more than two machines, you'd need a hub for 10BaseT.
