I was just browsing around the web this morning, and I saw this on the
Auction Web.
DWP 410 daisy wheel printer, paralell interface for the TRS80.
http://www.ebay.com/aw/item.cgi?item=oqb951
Seller's email: jruffco(a)adams.net
I know that some of you collect TRS models, and this item hadn't been bid
on, and the first bid was to start at $1.00. Also, the bidding ends today,
so I thought I would put this out in case anyone is interested. You can
occasionally find some good stuff on the auction web, but of course there's
always that yahoo out there with $1 more than you. Hope this helps someone.

I can definately vouch for Dan here! I've bought the system disks for both
my Osbourne Executive and the Kaypro 2X from him. He's very quick to repsond
to inquiries, and he's also very knowledgable about the different systems. He
posts on Usenet in the CP/M group quite often.

If the 386 BIOS goes by the same keystrokes and such as the Z-248 '286
BIOS, you should hit Ctrl-Alt-INSERT as the machine powers up to access the
built-in BIOS setup.

No, Zenith systems do not use a non-standard keyboard. It sounds likely
that it may not be getting that far.

If you remove the cover and watch the 8 LED's, you'll be able to watch them
progress from all dark, to all lit up as each POST test is completed. I know
on some Z-248's I've seen, there are even little captions silkscreened on the
board next to the LED so that you can tell which part of the test it's on. On
the Z-248 though, the LED's are on the main backplane board, on which the
processor, memory, I/O, diskcontroller, and any other board, plugs into.
Hope this helps at least a little. All of my experiece is with the 286
powered Z-248, but hopefully at least some of it will help you out.

Sorry to bug you guys again but after I post the original
message, the system I use for E-mail crashed big-time and
consequently, all my mail [40+ messages] from that day or
so was lost. I know a few of you replied to the question
and I would *really* appreciate it if you guys could kindly
repost your replies, either personally to me or back on
the mailing list.
Thanks!
Les
This is for all of you that are familiar with the TI-99/4 and 4A and it's
Speech Synthesizer. Does anyone know if there were any of the Plug-In Speech
Modules ever released? Granted, the reported 373 words (from the Synthesizer
booklet) is pretty good, it'd be nice if it were larger. Also, I'm looking
for any cartridges that used the Synthesizer, as the only two I have that do
is 'Parsec' and 'Terminal Emulator II'. I am especially in need of the
'Speech Editor' cartridge.
As an aside, I was going through the different manuals and such I have for
the TI-99/4A and found "Entertainment Games in TI Basic and Extended Basic"
>from SAMS in the Blacksburg Continuing Education Series. It still includes
the manual, TI Basic reference card, and a cassette with the programs on it.
According to the manual, there are twenty programs in all, and it looks fairly
interesting.

Well, I borrowed an eprom burner from a friend and pulled apart some of my
cartridges to see if I could copy one. I picked Atariwriter. Here's where
the confusion comes in. I am not sure what kind of eprom the cartridge
contains, so I read the left chip as a 2532, and as a 2732. I got two
different sets of data. I pulled them both into a hex editor, hoping for a
clue as to which on was the correct one, and they both had legible text that
I could recognize from the cartridge. How in the heck can I tell which kind
they are, or if I am even getting close. I copied both chips as 2732's and
2532's and made a set of 2732's with both sets of data, plugged them into
the original board, and nothing. This is really frustrating. I am hoping
that some one has done this at least once. This is my first time to use an
eprom burner, and I don't have a clue, except what I have read, and divined
>from the eprom burner program. I don't want to sound desperate, but I am
either barking up the wrong tree, or i'm in the wrong forest.
Thanks for any help, and all of the help I have received so far.

Ward,
I have the TRS-80 edition here among my different books, and it is indeed
by the same David H. Ahl. I think my favorite program in it is the Star Trek
game. I remember even getting to play that same game on a Honeywell mainframe
or mini of some type back around 1985 or so. In that version, there was a bug
that allowed you to create energy instead of using it if you put the warp
factor in as a negative number. We used to put it in as a very large negative
power or 10 or so, and that gave us more energy than we could possibly use the
whole game, all on the first move! BTW, on a similar note, I saw a web page
the other day about a reference book in the works, and it covered even all of
these early micro versions of Basic, and cross referenced the commands to any
other variant. I saw a book like this years ago, but it covered the popular
micros of the time such as the Apple's, TRS-80's, and such.

I saw this in comp.sys.tandy a few months back. I do not know the
disposition of the system. I would love to have it myself, but it
will be years before I could get the resources to properly open a
facility such as it deserves. The Boston Computer Museum has no
sense of _real_ history, IMAO. I did several of the mods Dennis
described, both those for the TRS-80 Model One and for the Color
Computer.

Hit a couple of thrift stores this weekend. Here's the stuff
I didn't pick up - if anyone wants any of it let me know and
we can arrange something.
2 Commodore 64's (9.99 US$/ea)
1 Blue Chip 5.25" Disk Drive (7.99)
^Can anyone tell me what this is?
1 Apple 2c (9.99)
2 IBM PC's (19.95)
1 Commodore Cassete Drive (7.99)
As for stuff I did pick up:
1 TI99/4A with no stuff - just the basic unit. I've never had a
TI99/4A before so this should be fun. My main question is - what
is the input voltage? I'm going to need to mod a power supply to
it before I can get anywhere with it.
Also an Aquarius Personal Computer Model 5931R from Radofin Electronics
(Far East) Ltd. Has anybody ever heard of this thing? I sure haven't.
It has small blue rubber keys and a template with basic commands
written all over it. It's about 30cm x 18cm x 4cm. On the back
there are three ports labelled Print, Cass, and TV. It has a big
cartridge slot (but came with no cartridge :(. I cracked it open
to see what's on the board but it has a big shielding cage soldered
all the way around the board edge and I just didn't have the time
to tackle that. Plugged it in and attached it to a composite
monitor but got nothing. The power light did come on. I'm guessing
it probably doesn't operate without a cartridge. Any info on the
thing would be much appreciated.
