Still can't find manuals. But here's what I know and maybe people can fill
in the blanks.
First info - Base model is 45711E, supposedly that designates 110+, 512k
ram, & modem. The memory drawer has a model 82981A, which googling suggests
is 128k ram addon. There's a metal shield over the chips and I don't have
the right torq bit to remove. Upon boot all the ROM ID shows BBBBBB.
First question - going into system config lets me set the memory split
between main memory and edisk. All choices add up to 896k. How does that
square with 128k + 512k?
Second info - The PAM menu shows the following application choices - DOS
CMDS, HP reflection, VT reflection, Memo Maker, Time Management, and BASIC.
However, opening up the software drawer shows the following chips in the
following locations 82863K-Reflection1 (0L), 45504K-MemoMaker/TimeMgt (1L),
82862K-BASIC (4L), 45555K-1/2-ExecutiveCardMgr (5H),
45555K-2/2-ExecutiveCardMgr (5L), 45548K-1/2-Lotus123 (6H),
45548K-2/2-Lotus123 (6L).
Second question - I assume the PAM menu selections for HP reflection and VT
reflection are handled by the single 82863K rom. I am curious why the
Executive Card Manager and Lotus123 don't show up in the PAM menu?
Misc. questions - The built in battery is obviously dead and won't hold a
charge, as the unit won't run at all without the AC adapter. Every time I
boot up though, it asks to reformat the A drive due to memory loss. More
importantly, it has lost the date/time and system config settings
(memory/edisk split for example). I'm curious if the date/time and config
settings are kept by a different battery I may need to replace, or if all of
the above is maintained by the single battery. I will have to hunt up a new
battery.
This 110+ is a really nice box! I'm quite fascinated by the built-into-rom
HP terminal emulator (dumb terminal emulation won't do) as well as VT
terminal emulator and serial port, all in a small package! Sweet!
Thanks for any pointers!

Rich:
I have a running 2000 here, that I can transfer files from. The 2000 does not have a BIOS like a PC. I believe the internal ROMs are just a POST and a boot strap, and the rest of the PC like BIOS is on the MS-DOS boot disk. I have been relayed this information by someone that used to develop and debug the 2000 for Tandy/Radio Shack.
Do you know a way to dump them? I guess if I knew their starting address and length I could use debug. I also have Microsoft's Assembler for the 2000.

PS I still owe you a phone call about the 2000s. I have one that I don't need, but it doesn't work. My suspicion is the power supply, but I've taken no time to verify this. This unit includes keyboard, HD controller, 10 meg drive and one or two 720k floppies, depending on the unit.
All:
I was able to get copies of the Tandy 2000 manuals for what is
going to be a pretty challenging emulation project that I've undertaken.
Since I don't have a 2000 system I was wondering if someone on the list who
has one would be able to make copies of the BIOS ROMs from their machine.
The BIOS/boot software is contained in two ROMs at locations U47 and U48.
U47 is the "odd" rom and U48 is the "even" rom.
Thanks again.

I'm trying to organize my PDP11 setup in a neat and tidy fashion, and I'm
wondering, aside from the DEC transition panels which would be ideal, what
sort of multi medium transition panels are there that I can attach things
like multiple RS232 ports and SCSI connectors, etc to?
The idea I'm after is something akin to the keystone patch panels, but with
things like full RS232-DB25 that just attach with a plate or something, much
like the DEC panels. Anyone seen anything like this?

I have it for Xenix on the TRS-80 model 16, but I don't think that helps much.

Hi All,
I'm afraid that I no longer have the room to keep either my DEC VAX
4000/705A or my DEC AlphaServer 2000. Both are in working condition.
Please note that the Vax is DSSI, not SCSI and has no disks, but does
netboot NetBSD/VAX nicely. It also has an internal DSSI DLT (unknown
condition as I have no tapes).
====
Hardware specs
====
VAX 4000/705A (aka Legacy+)
NVAX CPU (45 VUPS), 256Mb RAM, DSSI, no disks. Running NetBSD/VAX 1.5
ALPHA SERVER 2000 (aka Sable)
Dual 21064 200MHz CPUs, 196Mb RAM, SCSI RAID, 6x 4Gb HDD. Running Tru64
5.x
====
Both machines come from when I used to work at Racal. The Alpha comes
with media and documentation. The VAX doesn't.
I also have a couple of cisco 2500 routers up for grabs too.
Thanks,
Jules.
P.S. my "nospam" email address is real...

Some BCD computers had BCD memory addressing.
Also BCD instructions, though full binary data for
masking.

In a plastic bag at a local thrift I found a Tomy TP1103 blue/white
controller, but I can not find anything on using google. Anyone know what
system(s) this model works with? Thanks in advance for your help.
I've assembled a basic PDP-11/53ish machine from parts. The CPU is
>from a DECserver 550, converted back into an 11/53 by EPROM swaps.
It has an RQDX3 and cable management board, and a Seagate ST-251
(40 MB MFM) drive. This is all installed in a BA213.
So far, I haven't managed to get a load device working. I have an
RX50, but it seems unwilling to work. I'm trying to format the disk.
Jonathan Engdahl describes a trick to bootstrap XXDP utilities using
vtserver:
http://home.alltel.net/engdahl/xxdp.htm
Vtserver does its magic, ODT-ing in the loader, and transferring the
modified ZRQCH0 binary (from XXDP 2.5). At this point, the machine
seems to hang:
@p
Opened xboot.dd read-write
rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr EOF2
45Boot from vt(0,0,0) at 0177560
: vt(0,0,1)
Opened ZRQCH0 read-write
rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr EOF2
Boot: bootdev=06401 bootcsr=0177560
I have to cycle power to regain control.
Help please. Has anyone else ever tried this? Thanks,
De
