I would like to get a Tek 4404 computer going but lack any service
manuals. The system turns on but has no curser on the screen. Has
good power from the Power supply and heater is on in the CRT.
Has a row of LEDs on the mother board. Does anyone know how
to read these.
- Thanks, Jerry

time warp.
I found the manuals and software I bought in 2010, still in the unopened box
yesterday, and since then I got a base unit (no storage box).
Unfortunately, the firmware that was sent to me that I uploaded to bitsavers is
mostly FF's. Fortunately, I could read the eproms in mine, the lights blink, but
there is no video.
If someone has the scsi storage box, dumping the 6502 floppy eprom would be really
helpful (and maybe taking some pictures of the board).
Firmware and pictures of the inside of the 4404 going up on bitsavers today. I'm out
of time today to read the floppies, there are a lot, for 4404 and 4405, OS, C, Smalltalk,
and Lisp. Hopefully, readable.

turns out that one was good. the Adaptec 4000 dump was the bad one

the challenge will be bootstrapping without a tek scsi floppy.
Maybe I can borrow Paxton's if he still has it.
I'll work on reading the floppies today. They were in boxes and sealed in
plastic bags by the seller, so I'll try a couple that I have duplicates of
to evaluate their condition.
I've also sent a note to the MAME developers to see if they have any interest
in simulating the system.

OK. I misunderstood. There were no firmware listed in the adaptec/firmware
directory so I thought this was the problem. I also have the ACB-3530, the
ACB-4070, some Xebec S1410A and some OMTI bridges if there is a need for a
firmware dump.

yea, I should start filling that stuff in. It would be good to get your images
to start that.

I think I have the manuals for the ACB4520, ACB4000A and the ACB4070 in
addition to the ones that already are on bitsavers. Unless these are
already digitized somewhere else I could look them up and try to scan them
if there are interest.
BTW. The filename for one file is wrong. It says ACB3350A rather than 3530A.

thanks! it doesn't look like i have the 4000a or 4070 scanned, a little surprising
since I know i have them somewhere. 4520a is in the backlog

So far everything has been readable. They are double sided 40 track 8 sector 512 bytes
I've uploaded 4404 OS and C release V1.5 and V2.0 to bitsavers bits/Tektronix/4404
and am just finishing up V1.1
There are several revs of smalltalk releases with demo systems, lisp and utilities
collections
for the 4405/6.
