Hi all,
acquired few boxes with 3b1 & pc7300 stuff. Anybody is looking for parts
or complete units?
Cheers,

Philip Pemberton was looking for some things to help him finish his
simulator.

Are any American classiccmp-ers planning a visit to the Land of Earl
Grey and Scones in the not too distant future? :)
I'd really like to get FreeBee finished, but without the timing data
from the memory mapper, it's a non-starter... :(

No, probably won't be coming 'round anytime soon. But what exactly is your need?
An entire unit? No, I wouldn't be paying to ship that. But if there's a specific
part/s you need, let me know.

As a starting point, the base unit, keyboard and mouse. Emulating a
keyboard and mouse might be possible (I have a fair idea how the
protocol is structured) but wouldn't be something I'd like to try.
Display shouldn't be a problem, assuming I can get the
laptop-TFT-meets-scan-converter thing ("Das Frankenmonitor") to lock
onto the signal. I'm not above hacking around with the HDL code and PLL
settings to make that happen :)

I have one 3b1 and one 3b2/400. I'm searching for parts for the 3b1. More
exactly, one Lan Board, one memory expansion and one Hard Disk for
replacement (in case of death of the actual).
For the 3b2 I'm searching for one SCSI board and one Lan board. Other
goodings are welcome too.
In both case I'm searching for one Development System (C Compiler and so) in
diskette format (720k 5.25, If I remember).
I live in Spain.

There are two different, incompatible LAN boards.
1) There is a StarLAN 1 (802.3e, 1base5) adapter, which does 1 Mbps over
twisted pair, and is not compatible with anything but other StarLAN 1
products. This does NOT interoperate with any common 10Mbps, 100 Mbps,
or 1Gbps Ethernet products. In other words, while it is technically a
form of Ethernet, it isn't really the kind of Ethernet that anyone
actually uses. The adapter uses an Intel 82586 chip. The software does
not support TCP/IP. This card is somewhat rare, and IMNSHO mostly useless.
2) There is a 10Mbps Ethernet adapter, using an AMD Am7990 "LANCE" chip,
with a kludgey TCP/IP stack from Wollongong. The board has an AUI
interface, so you'll need an external transceiver (e.g., 10base2 or
10baseT). This card is extremely rare. The software only supports IP
Class A/B/C addressing, and does NOT support subnets (or CIDR).
To deal with the 7300/3b1 and other hosts with ancient network stacks
that don't properly handle subnets, I added a "bozo-arp" feature to the
Telebit Netblazer router, and later wrote a daemon for use on a BSD or
Linux box. It works by automatically generating a proxy ARP response
for any ARP request received on an interface but not within the
configured subnet for that interface.

Thank you, Eric. And I must say ' good job', by the way (with the ARP).

a set of disks (OS) would be most welcome. Although my 7300s h/d does work, albeit
intermittently, it would be fantabulous to have the original media (and I had the original
media, though it was worthless datawise, so I chucked it all. stupid). And I'd even
pay you something for it all. And freely make it available to others.

I know, but I have problems to grab them in diskettes. I probed with HD 5.25
units, with Dunfield (wonderful) utility, with bad luck. If someone can do
the job it would be welcome. And paid for the disturbs, shipping and
handling. Min is one 3b1 with 2 Mb and DOS emulation board.
Oj, and SAME for one ALTOS 586 in working state but with the XENIX kernel
damaged. A pity. A similar lot (grabbed) as the 3b1 set but for the altos
would be agreed.
Both with development system and network and scsi drivers, by the way.
