Got my 4D/25 TG running (Thanks, Robert) with a new 3010 FPU. I have
IRIX 5.3, but even in 32MB it's somewhat slow and a bit unstable. Has
anyone on the list used 4.0.5 or 3.3? I have talked with someone in the
area who has a set of 3.3 tapes, but I don't want to bother him if
there are usability issues, and I haven't talked with anyone about
4.0.5. Is there anyone who has used these? All i've seen are
screenshots and the fact that 3.3 is SysVr3+NeWS(?) and 4 is
SysVr3(+some r4)+X11, and that the IDO is needed for any practical
work. I have v5.3 & v6.5 Indigo2s, so I don't need it for 'serious'
work, just looking for recommendations & pointers.

A few people asked me for copies of the original Psion Organiser manual. I
finally got around to scanning it and posted a copy at
http://www.snarc.net/psion1.pdf for open perusal.

Hi,
I know this was an old posting I saw on the web. I just wondered if you still
have the CCS 2422 controller.
I have one and am in need of the U22 and U23 IC's or what is programmed into
them I am also looking to buy another card in any condition.
If you can be of help, I would really appreciate it!
Thanks!
Rich
I've never seen a proper spec or
anything (unlike for SCSI)
--
Because the standardization process is what created SCSI.
Look in the Xebec, Shugart, and DTC manuals on bitsavers.
There will be another batch of Shugart 14xx manuals up soon.
The big difference is SASI has no notion of deconnect/reconnect.
Once a transaction starts on SASI, no other device has bus access.
Anyone have service information on the Epson HX-20?
Specifically looking for information on the LCD driver.
I have an HX-20 in which the LCD has grown very dim ...
appears blank from normal viewing angle, but is barely
readable at very low angle...
Also, anyone on the list with a working HX-20 who would
be willing to open it up and take some voltage/waveform
readings for me (you will need an oscilloscope)?
Regards,
Dave

I'm setting up a YE-data 8" drive (YD-180) to use with a PC. I have
a couple of candidates, as far as which computer I use, but I need to
make sure that the onboard FDC will read and write FM disks.
I'm assuming that if I can write an RX01 image to floppy on the PC
and boot it on the PDP-11 (RX02 drive), I'm good to go?
Is there a list of FDC chips known to support FM?

I have a VT-131 suffering from video circuit problems. The logic
seems to be ok -- does a self test, led dance, emits a normal beep,
and ends with the on-line led lit. The crt filament is glowing.
Key click happens when keys are pressed. No screen display.
I've turned up brightness in set-up, flying blind. Haven't twiddled
the pot yet. So far, I've just taken the lid off, and am looking
into the still-assembled chassis.
The video board has some very charred-looking spots around the solder
pads of one component (cap? spherical white ceramic-like device with
two stout leads) down and to the right of the brightness adjustment.
The tech manuals from bitsavers and vt100.net don't give me enough
info to identify the component in question.
Anyone have prints they'd be willing to scan bits of for me? Or read
off to me by e-mail? Or have "replace this, kid" or "you're screwed"
specific knowledge of this scenario?
TIA,
De

Actually it gets hot due to the cap shorting or going leaky. Then
the diode and an associated resistor start heating excessively till
the cap shorts completely or the heat causes the diode to short.
It's a single point failure that was due to a underrated part (cap).
I was with TSG (Terminal Systems Group) when they discovered they
were getting killed by field failures of 1.7 years in service
(average age) VT1xx video modules. All because someone wrote
50V not 100V for the electrolytic used.
