TMC-885 Jumper Settings

Future Domain was bought out by Adaptec several years ago, and have two locations where you can get information of the cards from:

http://www.adaptec.com/support/overview/scsiha.html
ftp://ftp.adaptec.com/pub/BBS/FutureDomain/
** Default Setting

BIOS Memory Address - W1 & W2

W1	W2	Address
Open	Open	CA00:000 - CA00:1FFF **
Open	Closed	C800:000 - C800:1FFF
Closed	Open	CE00:000 - CE00:1FFF
Closed	Closed	DE00:000 - DE00:1FFF

IRQ Selection - W4

The jumper settings are read with the card in the upright position. A ':' means that the jumper is removed, and a 'X' means that there is a jumper in that position.

IRQ	Jumper
3	`X:::::::`
4	`:X::::::`
5	`::X:::::` **
10	`:::X::::`
11	`::::X:::`
12	`:::::X::`
14	`::::::X:`
15	`:::::::X`

Zero Wait State - W5

Open	Zero Wait Disabled **
Closed	Zero Wait Enabled

Floppy Address - F1

This jumper selects whether the floppy connector is the primary or secondary controller.

Open	Primary Floppy Address **
Closed	Secondary Floppy Address

AT Hard Disk Controller - F2

Open	No AT Hard Disk COntroller is Present **
Closed	AT Hard Disk COntroller is Present

Future Domain 25 pin connector pinout

The Future Domain SCSI card has a non-standard SCSI pin out on their cards. They look the same as the connectors used by Apple Macs, but are different.

Used on TMC-830/845 and TMC-850/860/885.

Note: Use the Macintosh pinout below for TMC-850M, TMC-1610M, TMC-1650/1670 or MCS-600

Pin 9 is NOT CONNECTED

Macintosh Plus SCSI Connector Pinouts

Note that this connector is NON COMPLIANT WITH ANY SCSI STANDARD! The grounding is insufficient and does not allow for proper twisted-pair transmission line implementation. It is recommended that a short adapter cable be used to convert to the more common Centronics style 50 pin connection rather than extend the 25 pin connection any further than necessary.

Pin 25 is NOT CONNECTED in the Mac Plus implementation. Newer Macs
connect TERMPWR to pin 25, but are otherwise the same.
