All,
In my ongoing effort at clearing space, I must part with my beloved IBM
RT-PC. This is a desktop form-factor with the "enhanced advanced CPU"
(don't you love 80s marketing-speak) running at a stunning 16Mhz. with 8MB
of memory on-board.
I have upgraded it with a 1GB ATA drive and an Adaptec SCSI adapter and
it's currently loaded with AOS / BSD 4.4. Has ethernet adapter and was
in-use on my own network.
Other items:
- A bookshelf or two of documentation
- One or two of every expansion card ever made for the unit
- Extra mouse and keyboard (non-standard connectors)
- Multi-Port serial card for POS systems (?)
- Complete software distribution of AIX 2.x
- Complete AOS / BSD 4.3
- The semi-mythical BSD 4.4 port w/ sources
- A couple of ESDI drives (original hard disk)
- The "academic" OS high-resolution grey-scale monitor w/ video adapter.
This supports X10 R-something under AOS.
And probably many, many other goodies that slipped my mind.
I'm open to negotiation on price, but the kicker is:
You Gotta Come And Get It. There's enough stuff to fill the back of a
small van and I'm not even going to address shipment.
I'm located in Burlington, VT. Please, someone give this a nice home?

Wow! I was working at IBM when the RT-PC was launched (1986?) I
actually have (acquired much later) a 6150 - the desk-side RT-PC. I
like the system, and I wish I could spare more time to work on it (well,
that's true of most of my systems, I suppose).

Wow again!
Other items:
- A bookshelf or two of documentation
On those weird square-page manuals in ring binders?
- One or two of every expansion card ever made for the
unit
- Extra mouse and keyboard (non-standard connectors)
Since I lack a mouse for mine, can I put in a plea that whoever does
adopt this system consider selling / trading me the mouse? 10 years ago
IBM told me the 6150 mouse was no longer available, but there was a
replacement, for which quoted me 150 pounds. They wouldn't tell me the
part number of the replacement, but I am pretty sure it was just a
Logitech PC mouse and an adaptor to plug it into the 6150. I tried
making my own connector (from a Compaq laptop power supply connector,
iirc), but had little success.

And that really is the kicker. Wrong side of the Atlantic, as usual.
:-( :-( :-(
I haven't a hope of picking this up, even if I had space for it, but I
really think someone should save it!

The same! Many boxes of them, I'm afraid. System, AIX, programming -
even the assembler reference :-).

Philip, if you think this will work on your 6150, you
are welcome to try
it. I don;'t have the mouse pad (and as I said it's optical, from the
time when you needed a special mouse pad for optical mice), and it is, of
course, untested..
Maybe if someone comes up with the protocol (or some reference for the
original mouse, like...schematics :oD) I can help in doing something like a
PS-2 converter :)
3:48 p.m.
It is a 6 pin IDP connector. Rectangular. One can make up a tail to
get to it by using a 6 pin IDP and a short ribbon cable.

I don't think it is. I agree it's the same spacing (I thought it was
smaller, but I just measured the one on my 6150 monitor), but I don't
think there's room at the ends for the clamps that hold an insulation
displacement block together.
It's polarised by the overlap of the metal shell, and the rubber
moulding around it, not by any of the keys normally found on IDCs.

Since you're the only person likely to be plugging it in, can;'t you just
mark it 'Top' or something?

Same as the connectors on the PCJr?

I don't think schemaitcs would help in this case. I'll
bet the original
mouse contains a microcontroller, and the firmware of that is what
defines the protocol.

Amazingly I've found it. The label on the bottom says :

The 5277 mouse is used with the 5271 PC/XT (or 5273 AT) 3270/G and
3270/GX. I believe it may connect to the top DE9 port present on some
models of the 3270 PC keyboard interface adapter.

I have -- somewhere -- an IBM optical mouse. I know nothing about it
other than it's 3-button, and IIRC the cable ends in a DE9 connector.
Inside is a microcontroller (8051). and not a lot else. I think I once
traced out some of the wiring back to the DE9 and came to the conclusion
tha the microntroller ran between the -ve supply line and something 5V
positiove wrt that and there was a transsitor buffer to make the output
RS232-like.

Unlikely, certainly the ones I've come across don't. You may be
thinking of two-button mouse operation under Linux; the driver can
detect simultaneous pressing of both buttons on a 2-button PS/2 or
serial mouse to emulate the middle button, but that's not what a real
3-button mouse does.

I've had zero response to this offer. The system is going to end up in
recycling if no one claims it by January.

Damn, I wish I was nearby. A plane ticket puts it out of my price
range. I'll check a map to see if anyone in the vicinity owes me a
favor.
