I' ve been intermittently looking (for many years) for a lowercase 2513 for
my ADM-3A. I was really happy to see your post and find that others are
interested in restoring this '70's nostalgia piece! I remember in 1977 how
impressed I was with the blazing 1200 baud modem speeds, since the hardcopy
Decwriters at the Univ. of Maryland were 300 baud.
(Also I have a working rackmount PDP-8/I, with a "University Computing
Company" front panel).
I wore out my keyboard this weekend searching online for a 2513. Pure
unobtanium. GI made them (I believe the p/n was 2513CGR-002 for the
lowercase? -001 is in the socket so obviously the uppercase). Just as well I
didn't find one, I never knew the address lines were flipped.... or am I
misunderstanding and it is the direct plugin?
thanks

Hi all,
I'm currently in a very good mood because I've found a Jupiter Ace in
near-mint condition, complete with 16k RAMPack, intro tape and a copy of the
book "Jupiter Ace FORTH Programming" by Steven Vickers. All this, including
the polystyrene box for the rampack (and rampack instructions) cost me the
rather feeble sum of two British pounds.
Now, there is a catch. The machine didn't come with a power supply. So,
can someone with an Ace, working PSU and a multimeter please tell me what
the polarity and voltage of the PSU's output is? I'm hesitant to power up
the Ace in case I end up fouling up the settings, with fairly predictable
results.
Thanks.

I have old Sparc Sun machine which I would like to run on Solaris 2.4, not newer. I have Solaris 8 from a few years ago when I paid Sun $75 for CDs but I do not want to run this version or the 2.5 I have from another machine. Does anyone have Solaris 2.4 CDs that they could sell or copy for me? Please note that I am not looking to violate copyright law but I do need to get 2.4 and not some later or earlier version of Solaris. Alternatively, does anyone know anyplace where I could obtain Solaris 2.4? (I have watched Ebay for 6 months without seeing a copy of Solaris 2.4 for sale)

I have already responded to Bernd, but thought I should pass the info here.
I have
the whitepaper for this particular board, but nothing else. According to
the paper,
it is B004 compatible (most if not all PC boards are), so the software on
the website
*should* work. Here is the link to the whitepaper:

Cheers,

PS: As a side note, what is a good way to scan documents in such a
way as that the resulting PDF document can resize as large as possible
without loosing image quality. Word documents can resize as large as
possible
without image loss. I hate putting word docs on the website....

This is a common problem with transputer based hardware...

No, but most PC-Transputer-Boards where compatible to the
Inmos B004 interface.
On Ram's Transputer Homepage you should find a lot of software for
this interface (http://www.classiccmp.org/transputer)
I'm writing a Linux based development environment for transputers.
Currently only the B004 driver and the assembler are operational.
If you find any useful information regarding the interface of your
board I would be very interested...

I'm sorry, but if you redirect the printer port to a file, with something
like the dos vprint tsr, no typing would be needed because the print job
would be on the disk already.

I have a spare D780C with a 1983 date code. Mail me off-list if you want
it.
I think the original may have been socketed. It was common to socket
thingss like MPUs, ROMs, etc, in those days, but the 1984 date code sounds
late -- I think the Ace came out in 1982.

You're right. Too long since I worked on this, I apologize. Unless you
specify a read-all or write-all, the RK05 does check at read or write.
I should have kept my mouth shut. :-)

Surplus to requirements: SynOptics Lattishub 2813. This is a managed
10baseT hub, with 16 x 10baseT ports, modem port (for remote management),
RS232 port (local management), and an AUI port. Cosmetically good, in
perfect working order, and I even have the manual, but I've replaced it
with some fancy black ATM/100baseTX kit. Free to collect from York, or pay
carriage (not too expensive; it weighs about 3.5kg).
