I've been working on a Linux driver for the Adaptec APA-348, a parallel
port SCSI adapter. This device used to be known as the Trantor T148.
I need to confirm some hypotheses, so I have prepared a small
user-mode program that should be able to detect a 348 and scan its
SCSI bus.
The program is available at ftp://ftp.torque.net/pub/trt.c
You should have a 348 hooked up to your machine, on a port that is
not being used by any device driver (including lp) with at least one
SCSI device attached. Please be sure that the SCSI bus is properly
terminated.
As root, you can run trt giving the port's base address as a command
line parameter. The program should report if it found an APA-348
at that address, and the results of scanning the SCSI bus.
For example:
# trt 0x378
Adapter signature: 6c 55 aa 6c 55 aa
There appears to be an APA-348 at 0x378 using 8-bit mode
0: SyQuest EZ135S 1_10
2: NEC CD-ROM DRIVE:36 1.0
I know there are many people who have been waiting patiently
for this driver. If you have a 348, please do this experiment and
send me the results as soon as you can.
If you have an APA-358, I would also like to know if it responds to
the 348 protocol.
The 358 is an "enhanced" version of the 348, it supports EPP, the 348
supports only 4-bit and 8-bit modes.
It is especially important to find out if all instances of the 348
return the same basic signature string, so if the first three
numbers of the signature are not as shown above, I need to know this.
