Anyone have one of these development systems?
I've had the manual for a while, and I think I just found a bunch of software for it.
Looks to be Multibus-based from the pics in the manual on bitsavers.
After long deliberation, I have decided to let go of one of my nicest
best machines. It is a 2 rack config and comes complete with spares etc.
For all details & history of this machine, see
http://www.groenenberg.net/download/1135
Please contact me off list for more details if wanted, as well as
offers for this machine.
Please note, no cherry picking, this is an all or nothing deal.
Regards,
Ed

Zeg NEE tegen de 'slimme' meter.
As an FYI, I recently purchased an Ethernet card, 3Com Assembly number
2012-01 (I believe this is a 3c505). It works perfectly.
I am now in the process of attempting to read in as many of the (over
100, maybe 50 or so without duplicates) tape cartridges as I can, and
will forward them off to Al Kossow that CHM when I get them read
(presumably on a DVD).
The biggest issue with the tapes is that Apollo used some pretty cheap
cartridges at time to deliver software (after all, why should they need
to last?? 8^)), and the little rubber belts inside the QIC-24
cartridges have gone bad in many of them. Fortunately, I have some
relatively newer 3M DC600 cartridges that I can use to supply a
substitute belt, and when done carefully (e.g., first manually rewind
the cartridge PAST the load point (but not past the end!) before
switching the belt to avoid problems) seems to be working.
Unfortunately, I blarched a set of SR10.2 install media learning all of
this. 8^P) But, I just read in a tape of 12MB successfully after doing
a belt replacement (a tape with DPCI software, I think - it is still in
the drive).
In addition, many of the tapes I have were left in the middle, which
seems to present data readability issues. We'll see.
You can find these Ethernet cards on:
EBay right now has two of them:
http://www.ebay.com/itm/3COM-ISA-Ethernet-Card-2012-00-RevB-/350290188652?p…http://www.ebay.com/itm/3Com-2012-16-Bit-ISA-Ethernet-Coax-Network-Card-/19…
And also at Pinnacle Micro / EZ-Systems may also still have some. Part
number ASSY-2012-01 "ASSY-2012-01 3Com
Refurbished Assembly 201201 ETHERLINK 16 BIT 30 Day Warranty"
They are $28.75 from Pinnacle, but the minimum with shipping is $50, so
you end up paying $50. Suggest adding a comment that you do indeed want
the "LONG version of the card" (they called me to confirm that). I got
mine there because they offer a 30 day warranty (at least on the one I
bought), which is what motivated me to drag out my DN3000 and try and
read some tapes and FTP the files and test them with the DN3xxx emulator
inside of the "mess" simulator. Even one of the bad SR10.2 boot tapes I
could at least boot from after the transfer, and enough of the tape was
there that some of the programs would run (e.g., calendar, invol, config
all ran).
I saw at least one card somewhere else on the net for a reasonable
price, but I forget where.

Re 480z
Hi Jules
As far as I know the metal case was an inner London education authority variant (ilea). At that time every piece of electronic equipment used in the authorities schools was retro fitted with huge "child proof" casing. This meant that every electronic item had ugly GLC boxes fitted before we could use them. The 480zs were issued to all ILEA schools in this form in the early 80s. I remember using them at that time and wishing we had the BBCs. The rumour was that they'd done a deal with RM.
Hope you don't mind me contacting you like this. You email came up on a search I'd put in for the 480z

Mine is running. Well, not now, I'm typing.
Maximum clock rate seems to be about 1 Hz for reliable operation; I
have not tried ice-tea cooling for over-clocking.
I have implemented a 1-bit + 2-bit adder, output register obviously
the same as the input registers (concatenated), and a 3-bit counter
with rollover.
Pretty sure I'll need a memory expansion to implement tic-tac-toe.
I highly recommend playing with it! No connection to seller, but had
much fun, even without overclocking.

Hi all,
know it sounds weird (but I travel a lot, laptop user on the road).
Anyway, does USB-SCSI adapter exist, if yes, are they really worth the
money?
My laptop doesn't even have PCMCIA slots anymore ...
Cheers & thanks

I was just looking at the picture and googling for any info. I don't
have any experience with this product but the fact that it's called an
"rtVAX 300" suggests to me that it may run VAXELN, a Pascal-centric
real-time application environment.
This may be an application engine for running a VAXELN app. I saw
some presentations at a DECUS or two but never worked with it.
