This may be old news to most. I have never been exposed to the PDP-11
series, but I know a lot of you are big fans. I accidently came across
another RPI alum who offers his PDP emulator free for non-commercial use, so
I though Id post some info about it:
D Bit
Developer of Ersatz-11, a software PDP-11 emulator for MS-DOS PCs giving
emulation speed far faster than the PDP-11/93. The free demo version may be
used for 30-day commercial evaluation, or unlimited personal/hobby use.
Information about commercial versions is available here. Take a live RSX11M+
V4.5 system for a test drive here.
----------------------------------------------------------------------------
PDP-11 Emulation System
Try out a live RSX11M+ V4.5 demo system
Ersatz-11 emulates an entire PDP-11 system in software while running on
low-cost PC hardware. It outperforms all of the hardware PDP-11 replacements
on the market, outstripping them by a particularly wide margin in
disk-intensive applications. Hardware PDP-11 replacements that use a Q-bus,
Unibus, or ISA bus for I/O can't come close to Ersatz-11's disk performance
because they are limited to the speed of the I/O bus for all disk transfers,
regardless of actual disk (or disk cache) speed. Ersatz-11 avoids this
bottleneck since it uses the PC's main memory and takes advantage of the
tight disk-to-memory coupling in modern PCs.
Ersatz-11 is by far the least expensive PDP-11 replacement product on the
market. It quickly pays for itself in reduced maintenance, power, and
climate control costs. Since its CPU is powered by the PC's processor and
not a special-purpose processor card, there's no expensive custom hardware
to maintain, and future upgrades to the PC's processor will make its PDP-11
emulation even faster.
Orders for Ersatz-11 are usually shipped out the same day.

I have no idea if this is new - no idea if the product is good, bad or
indifferent. Just thought somebody might be interested.

i need info on an old ibm system/34 it is operational and i have
terminals for it but they wont connect to it. also i need
to know how i can hook a DOS computer to a win95/98 network and i
have an old iomega disk drive that takes 20meg
8 1/2 inch cassettes i need drivers or info on how to set it up
Y2K compatible dir listing including the TSX+ time stamp, but doesn't
<support all those innumerable switches yet), PIP.SAV and DUP.SAV would be

One possibility is to not try to make DEC compatable utilites and develope
a set of basic utilities so people could develope with and on fuzzball.

Had a pretty good Saturday got the following items:
1. Mac Powerbook 170 with adapter needs a little work but was 29 dollars.
2. Sear Tele-Games Super Video Arcade game with 12 cartridges and 2 paddles.
3. 22- Atari 2600 cartridges, two were new to me. Gateway to Apshai and Haunted House.
4. A Grid 286 and 386 notebooks.
5. About 25 books and manuals for the collection.
6. New in the numeric keypad for the Apple II by The Keyboard Company.
7. Several new mouse pads for that part of the collection.
8. About 10 new cups to add to that part of my collection also.
All in all it was a good day since I also picked up several other items that are 10 years old yet but were too good to pass up.
Hi,
Disk-2-Disk is an old commercial program for the Amiga by Central Coast
Software. There is a demo of it on Aminet (misc/emu/D2D_Demo.lha).
D2D can be used to read data from C64 disks in an unmodified Amiga 5.25"
floppy drive. According to the documentation in the demo archive, reading from
tracks 1-17 is really slow because the program must do some tricks to account
for real 1541 drives having variable speed. (There is a program on Aminet,
misc/emu/1541.lha, which can read 1541 disks but this requires that the Amiga
drive's speed be reduced.)
Does anyone have an original copy of Disk-2-Disk that they would be willing
to sell? If you do, please contact me.
Regards,
-- Mark
<John has also been a list member for a few months :^) Downside of his is
<you have to *OWN* a copy of the OS to use it legally. You can't use the
<Hobbyist Emulator license. That only applies to Bob Supniks emulator.
You can use it to run some of the unix binaries available fromthe PUPS
archive. Though for $100 you can get a source license too.

Here's the deal; I've been offered some PDP stuff in Oakland (details in
forwarded message below) and am trying to negotiate pickup. I'd originally
contacted the company searching for documentation on an obsolete product,
and got much, much more...
I'm in LA and the trip would be exceedingly difficult to arrange for
myself. Anyone in the Bay Area who is interested in anything he's got
and can give me a hand let me know; if worse comes to worse, I'll fly up
and ship it back.
Cheers,
Aaron

Hi,
We have a fair amount of info on that board - I will see what I can dig up
and let you know.
Do you or your group have any interest in more LSI-11 related documents,
boards (CPUs, serial boards, disk controllers, etc) ST506 drives (36-200 MB)
etc? Also, a bunch of DEC blocks and PCBs (I think we still have those) for
building backplanes. We have quite a bit of this stuff lying around and I
haven't been abe to bring myself to throw it all away. New, of course, it
was worth a lot, but now it isn't worth anything except to the knowledgeable.
It would be a regular treasure trove. It's too bad - I have already gotten
rid of the BA11 boxes and things like that, but there are lots of boards,
drives, misc h/w, s/w, etc. Also, a really nice HP plotter, a Pacific Page
plotter, and a few goodies like that. A bunch of 300w power supplies that
are good for building machines up. Any - lots of surplus stuff that would be
appreciated by a group that needs such things.
If you want it, and would give it a good home (whatever that means), I would
be delighted to give it to you. Maybe somebody could drive a pickup up here
sometime and we can load it up. If you don't, but know someone who is a real
DEC '11 freak, please pass this mail on. I hate the idea of giving it to the
garbage man, but I need the space for other things.

This one made me chuckle when I rescued it. It's a "Personal Application
Kit" for the NEC PC-8201A handheld computer. It consists of a single data
cassette (yes, a cassette -- looks just like an audio cassette, too) that's
still in unbroken shrink-wrap and a user's manual.
It's vintage 1983, based on the copyright, and contains the following apps.
Memory Calculator
Text Formatter
Investment Portfolio
Linear Forecaster
Loan Evaluation
Schedule Keeper
Character Definer
Bank Backup
Bank Transfer
Bank Accessor (these latter three seem to have something to do with
internal memory).
Terminal Mode Selector
Bar Code Reader
Music Programs
Tank Game
Snake Game
First person to offer me $8.20 ($5.00 + Priority Mail shipping) takes it.
First-come, first-served, based on E-mail time/date stamp.
Thanks much!
