Hi all,
by surprise I got a Tadpole Sparcbook 2 some time ago.
Sadly there seems to be almost no documentation available in the net for
a Sparcbook 2, neither a technical/service nor a user manual, only for
Sparcbook 1 and later models.
I do have the following issues:
- the battery pack is missing.
I found two ressources, e.g. the CHM - but none does have any infos
about the battery pack
- The external power connector requieres 18V - no problem
- After connecting the fitting power the Sparcbook does power up, the
display is lit and the unit is trying to boot from the internat SCSI
disc. Nevertheless the boot process is failing this is a good sign.
- after trying to reboot the unit will be almost dead. While pressing
the power on button the LEDs on the left upper side of the display will
be lit shortly, but nothing else will happen.
- trying to reboot an power on the same as above will happen
If I'll keep the unit several weeks/months unpowered the unit will power
up again - but of course will be stuck again while trying to boot from
disk and the same semidead issues as noted above.
I'm suspecting the TOD chip/battery is deads or are there any other
sugegstions?
Up to today I didn't have a look inside of the unit ...
Does any have the manuals hidden in theirs shelves?

There is a copy of the Convergent CTOS EDL (ethernet data link / packet driver) for the ETH150 (SMC 8416T ISA ethernet) board on Bitsavers.
I am wanting to make use of an SG410P (CTOS EISA Ethernet IOP) but as far as I can tell the EDL archived on Bitsavers is missing the piece(s) necessary for use with an IOP or other supported non-ISA ethernet board.
Has another copy of the EDL survived? Can it be made available? It might be the case that it was included as a separate disk in another CTOS networking software package (e.g. TCP/IP, OSI Transport, or LANce).
Secondarily, CTOS FTP has ISAM II as a pre-req; Bitsavers has (what appears to be) an update-only disk archived, but no “base” install. I’d be quite interested in finding out if that has survived and could be made available as well.
If there’s a more likely mailing list or forum I might also direct my enquiries, I’ll be glad to engage there. Thanks!
ok

Does anyone here have or know of ComputerVision CADDStation input devices (e.g., puck, tablet) that ard for sale? I have started restoring the CADDStation Model 32 that has been sitting in my garage for a while but am missing some pieces to get the full experience.

I was given an ASR-33 complete with stand, read & punch.
This ASR-33 has been modified for RS-232 though a blue perfboard mounted
in the connection enclosure (under the cover place where the dialer
would be.
Is has a DB25 ribbon cable coming off of this board. The perfboard does
not have a label on it that I can find.
The ASR-33 also has a 3 x 5 conductor rectangular connector coming out
of the read of the unit with 6 female contacts installed.
I was able to connect the ARS-33 to a VT-330+ at 110B 8-N-2 and send and
receive on the teletype.
The punch seems to work as well.
The reader will "chatter" then the reader is put in the stop position
and the tape out sensor is pressed but the sprocket does not advance and
the reader pins to not move.
Questions:
1. Why the reader is not advancing and the pins are not activating?
Could this be a read enable contact not being in the active position?
2. What are the outs of the RS-232 DB-25. Other than TX, RX and GND
3. What are the pin outs of the 3 x 5 rectangular connector. I think
this is the current loop and other control signals.
Does any any of the items below for sale or have a 3D model I can print:
1. Roll Paper spindle (the spindle that the roll paper spins on)
2. Paper Tape Punch Spindle (the spindle that the paper tape spins on)
3. Paper Tape Chad feed tube
4. Paper Tape Chad Box
I will be connecting this to either a PiDP-8/I or a PDP-8/E for now and
eventually a PDP-8/L
Thank you,
Mike
Hello all,
I have transferred some simh .tap files to my PDP-11/23+ running RSX11M+.
There I have tried to use VCP to attach them to a virtual device but I keep
getting an invalid record format error. I then realized the simh .tap files
most likely aren't organized correctly. If I attach them to TS0 in simh I
can work with them. So now I am trying duplicate a tape into a new .tap
file created using VCP. I can't for the life of me get it to work though.
BRU doesn't support tape-to-tape and FLX doesn't complain but also never
completes. Is there a process for tape duplication under RSX?
The images were first transferred to my PiDP-11 using ftp in binary mode
over TCP/IP. From there I used NFT in image mode and I tried both record
and block modes.
I have also seen the simh tape tools but there doesn't seem to be a tool to
convert a simh file back to what would be on a real tape.
Anyone have any information or pointers to get this to work?
Thanks!

Swap Meet Update 6/4/25
Weather
The weather on Saturday is being watched closely. A little rain is not
concerning, but the thunderstorms are concerning. We will make a final call
on Thursday at 10PM about what we will do. We will post updates here:
https://vcfed.org/vcf-swap-meet
Food Truck
The food truck cancelled on us and we can't find a replacement at the last
minute. We *may* have some solution to support at least the vendors and
volunteers. The general public are on their own.
Otherwise we have plenty of vendors signed up with lots of interest. We
have been posting daily on Facebook & Instagram to tell everyone about the
event. Lots of engagement, interest and excitement.
Take care!

I have an AT&T branded SCSI enclosure. Two half-height bays with the
drives held vertically (on their sides), with a door that opens to
expose one for a tape drive, activity lights labeled hard drive and
tape, CN50 connectors, the AT&T beige and brown
color scheme I associate with 3B's and 6300 PCs. No model number.
Anyone have any idea what this was made for?

I am going to assume there are other TRS-80 people hanging out
here and go ahead and ask this:
Has anyone here used the DEFUSRx command?
I tried to use it for something I am working on and it
didn't work.
So, I copied the example program from page 115 of the
Model III Disk System Owner's Manual and, guess what,
it didn't work either.
150 DEFUSR1 = &H7D00
returns a Syntax Error
150 DEFUSR1 = 32000
works fine.
Anybody else ever run into this?
I can't believe something as blatant as that could have
gone on for all those years.

It is few years that anybody asks, so here it is again:
ANYBODY has any manuals for it?
On Discord, we have some discussions, I found some of them in my boxes,
but nobody has documentation, and no success to get them working.
Any chance?
