Do you know anyone who wants an early serial number Britton-Lee Data Base
machine. The first of the kind. It can be had for the cost of
transporting it from Los Angels to wherever.

I get a 554 code ?? Thanks loads for the info and I hope this code is not
a bad one.

A couple people (Richard Cini, William Hayes) were interested in the
terminals and requested more information. Here's some blurbs from the
manuals:
First the CIT-101e Video Terminal by CIE Terminals (a C.Itoh electronics
company):
The CIT-101e is directly interchangeable with the Digital Equipment
Corporation (DEC) VT100 Video Terminal. The CIT-101e can operate in one
of two modes, ANSI or VT52. In ANSI mode the CIT-101e is compatible with
American National Standards Institute (ANSI) programming standards. In
the VT52 mode the CIT-101e is software compatible with DEC VT52 terminals.
Standard features include a full and half duplex communication channel,
RS-232-C or 20 mA current loop communication interface, an auxiliary full
duplex port, an alternate character set, and temporary storage of up to
three display pages.
Next, the AT&T Information Systems DataSpeed 4425 Display Terminal:
Hmmm, well there's no real good descriptive blurb to type up like the CIE
manual had. This terminal can be configured in the setup to do VT52
escape sequences. I don't think it has a current loop interface as I
don't see any mention of one. It does have an "integral modem", which is
actually an external box. It goes up to 1200 baud. You can dial the
modem right from the terminal by hitting the F1 key.
Both these terminals can do 132 columns. I don't know if that excites
anyone but I thought I'd mention it.
I'll tell the guy to hold off on dumping them until you folks have made up
your minds. Again, there's also a ton of switchboxes, cables and gender
changers.

I thought it odd that the M-number for the memory card is listed in some info
that I have as "1mb MOS memory card", but Ultrixboot reports 4mb of RAM. I
don't recall seeing a letter suffix, but frankly, I wouldn't have known to
look -- this is my first DEC system, so I'm not familiar with their numbering
conventions. I also haven't yet pulled the cards from the backplane in order
to inspect them. My time has been spent rebuilding the power cable and trying
to get the external RD52 to work.
From "memory", here's the backplane configuration:
Slot TOP BOTTOM function
8 open open
7 {M7954?} open buss extender
6 M8639 {same} RQDX1 disk controller
5 M7502 {M7948??} Ethernet / {slot filled}
4 M3104 {same} serial EIA mux-8
3 M7551 {same} memory
2 M7135 {same} processor 1
1 M7136 {same} processor 2
I can't remember what's in the remainder of slot 5, but since the unit has
floppies, the M7948 is a guess. I'll take a better inventory tonight.
More to come...

this was posted on comp.sys.zenith.z100. $100 seems high to me given the
condition of this machines and the fact that it's a bare bones
configuration - i recently got one of these plus tons of software for free.
these puppies are heavy too so watch the shipping costs.
on the plus side: this is a very nice CP/M machine. S-100 bus; dual CPUs
(8085 and 8088) and much of the CP/M BIOS actually executes on the 8088
CPU! please reply to the original poster (not me). tx.

Subject: z-100 for sale (circa 1984)... cheap?
I'm offering the following dinosaur for sale:
Zenith Z-100 computer (bought as a student at Clarkson College in 1984):
256K RAM (I will also throw in the original 192K chips) Monochrome display
2 5-1/4" "Half-height" Floppy Drives Video memory for shades of grey *NO*
hard drive!
Software for above: DOS, Z-BASIC, Multiplan, Pascal/Fortran Compilers,
Turbo Pascal A few other disks with games and utilities.
Condition: good, a couple of keys don't work too well. Computer has not
been used in the past 6 years.
Price: I'm looking for $100 *plus* shipping but will consider any offer. I
want to get rid of it by December or else it will probably end up in the
computer graveyard.
For more info or bids, contact: John Pfuntner, pfuntner(a)pobox.com.

I know a guy who has a few old dumb terminals which are brand new in the
box (with the original packaging tape on them) circa 1982 or
thereabouts. I bought a couple from him at a weekend swap meet for $5 a
piece. He still has about 4 or 5 more. He also has a bunch of new in
box 3to1 or 2to1 switchboxes, as well as a whole mess of brand new
shielded serial cables, some in lengths of 20' and perhaps 50'. All this
will go to the dump unless someone wants them. He's willing to ship and
will take very little for them. So if anyone wants a brand new dumb
terminal or some cables, let me know and I'll pass you along his number
(I don't have it on me right now). He's local to me and I could arrange
to ship.

I just got some service manuals for the old Zenith system today and will
send you some info as soon as I read them.

Silly me; I assumed you meant "hard sectored disk controller". In this
case, a synchronous serial chip with its SYNC input attached to the drive's
Index pin.

Wayull...I don't deal im Macs, so I don't know prices. I'm just passing

$300!? I know its not april fool's day. I must have got a deal of the

when I got a mac ][cx and 3.5 drive for $25...

This one has a built in Percom floppy (the kind with the big door), so
it must be an H89. It says H88 on the back, but if an H89 is just an
H88 with the floppy controller + drive, then this one has been upgraded
to an H89. Cool, I'll order the H89 CP/M from Don.
The front badge just says "Heathkit Computer".
