Firefly dual processor card

[Mark Kahrs via cctalk]

Against my better judgement, I obtained a DEC SRC Firefly dual processor
card.  If i read this* correctly, then this card is interfaced to the
shared memory bus (MBUS) as opposed to the QBUS (the card uses a Q bus
format).

I realize it's probably hopeless, but I'll ask anyway: Are there any
schematics or specifications on the connectors anywhere?

*IEEE Computer, also available on Bitsavers as a technical report.

For Sale: RCA COSMAC VIP with SC/MP II co-processor

This is a very cool COSMAC VIP that has been slightly modded to act as a

front panel for the SC/MP as well as some interesting add-ons for the VIP
(PROM programmer, Tiny BASIC ROM card, CDP1855 math co-processor) and more.

Full description and links to photos here:

Well, the vast majority of computers 'back then' numbered bits (and byes)
from left to right - which is why in numbers in TCP and IP, the bytes go from
left to right (necessitating byte swaps on most current architectures before
sending a packet out into the network).

The majority of computers being attached to the network when TCP/IP was being
defined used that byte order (I think PDP-11's were the only exception, but
I'm too lazy to check a copy of HOSTS.TXT to make sure), and so that's what
we're stuck with now.

So, I can see, centuries in the future, the bytes in a word on the Internet
(and it _is_ capitalized) still being in an order set by long-dead computers.

Kind of like how rail gauge today still mimics the width of Roman carts (yes,
I know the story is only half-true, but it's not wholly wrong).

The minimum legit voltage swing for RS-232 is supposed to  be plus and minus
5 volts and the
maximum allowed voltage swing is plus  and minus 25 volts.  The problems
occur when gear didn't
bother to  do the negative swing to minus 5 volts.  Plus and Minus 10 volts
is  more than adequate.

The  ribbon on my 43 is a reinking type.  The ribbon loop is maybe  18
inches?  I have a new in bag
ribbon which I am sure is also  dried out.  I used a drop of thin oil on the
reinking roller the last  time
I messed with it and that seemed to work.  You probably want to  use
something that will lubricate
because the pins on the dot matrix  print heads do need that to keep them
from rusting and  wearing
out.

The "stutter" you mention is normal.  The printer  electronics buffers a few
characters during the slow
carriage return and  prints slightly faster than 30cps so when a new line is
started it goes at  full speed
until the buffer is empty at which point it goes into the  stutter mode.
This eliminated the need to send
nulls after a carriage  return that was necessary on the earlier purely
mechanical  printers.

DEC rack-mount AlphaServer 2100A

[Paul Birkel via cctalk]

If there's anyone out there with a rack-mount DEC AlphaServer 2100A - the
one with the underslung pair of power supplies -- I'd appreciate your help
in determining the 15-pin control-cable configuration for J3.  It may
require examining the other end of the "power supply control cable assembly"
P#17-04014-01, which is 24-pin (to handle the dual/redundant power supply
configuration).

 

Available hardware documentation is pretty sparse.  Physical examination of
an AlphaServer 2100A system backplane (54-24129-01) would certainly help!

 

While I'm pretty sure that I've figured out the +5V +- sense lines (pins
3-4), and the +3.3V +- sense lines (pins 15-14), I've failed to determine
the purpose of other control lines - most particularly which one(s) turn it
on.  Pins 10 is suspect, but there's no obvious reference point for voltage
measurement or evidence whether it should be shorted to another pin, or .
something else.

 

There's no control relay or other obvious mechanism.  The PCB is
dense-packed with surface-mount components on one side and power components
on the other; tracing circuits is a bear.

 

Applying AC starts up the 24VDC fans, but none of the four switchers kick in
:-<.

 

Thanks for any clues!

Anyone remember ZOSO disks?

[Amardeep S Chana via cctalk]

Back in the 80's I had some archive disks (maybe SIG/M or CPM/UG or maybe
something else?) which had files on the disk named like ZOSO.022 (for disk
#22) which was the Star Trek basic game disk.  I'm attaching below the text
from that file (best viewed with a monospace font).  I seem to recall this
person who went by the moniker of Zoso had written others as well, but I
can't find them right now.

Just curious if any of you had seen those and if anyone knows who this
mysterious Zoso person was?  If I find others I'll post them.

THIS DISK CONTAINS THE FOLLOWING FILES:


STARTREK.TXT THIS IS THE ORIGINAL SOURCE FILE FROM WHICH THIS PACKAGE WAS
DEVELOPED. IT IS PURPORTED TO RUN AS IS WITH MITS 8K BASIC. IT
CONTAINS ALL THE REMARKS, AUTHOR CREDITS ETC. IF YOU HAVE THIS
BASIC WITH ASCII-LOAD CAPABILITY, TRY IT !!

BIGTREK.ASC THIS IS THE RESULT OF HAVING TRIED TO TRIM THE ABOVE SOURCE SO
AS TO GET IT TO RUN (IN A 64K SYSTEM) WITH MICROSOFT'S MBASIC.
IT PRESENTLY IS ALMOST SHORT ENOUGH, BUT NOT QUITE. BECAUSE OF
THIS, THE OBJECTIVE BECAME TO MAKE IT SUITABLE FOR TDL'S DISK
BASIC RUNNING IN 64K. IT RUNS QUITE NICELY THAT WAY. ALL OF THE
FEATURES OF THE ABOVE PROGRAM ARE RETAINED, AND A COUPLE OF NEW
ONES HAVE BEEN IMPLEMENTED.

BIGTREK.BAS THIS IS THE COMPACTED MACHINE CODE OF THE ABOVE FILE WHICH
LOADS ABOUT 50 TIMES FASTER THAN THE ASCII VERSION (TDL DISK
BASIC ONLY). THE PROPER STEPS TO LOAD THIS ARE AS FOLLOWS :
(ASSUME YOU HAVE LOADED TDL BASIC INTO A 64K SYSTEM)...
1 - OPEN#1,"I","BIGTREK.BAS"   
2 - LOAD "B"
3 - CLOSE#1,"I"
4 - RUN

TREKINFO.DOC A BRIEF TUTORIAL ON THE RULES FOR PLAYING THIS, CROSS-REFER-
ENCED WHERE POSSIBLE WITH THE FAMILIAR COMMANDS OF THE MORE
COMMONLY AVAILABLE 'STARTREKS'.

TREKMOD.ASC SEE EXPLANATION (IN POST-SCRIPT).

STRTRK/2.ASC THIS IS INCLUDED BECAUSE I LIKE THE 'COMMUNICATIONS' AND 'MIS-
SION-PROGRESS-REPORTS' THAT HAVE BEEN IMPLEMENTED IN THIS MUCH
SMALLER (STILL > 20K) VERSION.

NO MATTER HOW YOU GO WITH THIS, IT IS LIKELY THAT YOU WILL NEED 64K (PERHAPS
60K IF YOU USE 8K BASIC) TO RUN IT AT ALL. ONLY GUARANTEE IS THAT IT WILL
RUN
WITH TDL DISK BASIC/64K AS IS.

SINCE I CAN RUN THIS, I LEAVE IT TO SOMEONE ELSE TO GET IT WORKING WITH
EITHER
MICROSOFT DISK BASIC (OR BASIC-E). ONE SUGGESTION FOR THE FORMER PROJECT
MIGHT
BE TO PARTITION THIS PROGRAM INTO TWO MODULES. THE FIRST WOULD CONTAIN ALL
OF
THE LINES RELATING TO GALAXY INITIALIZATION, DIMENSIONING STATEMENTS, DATA-
TABLES AND ALL BEGINNING OF GAME DIALOGUE - IN OTHER WORDS, LINES NOT REFER-
ENCED AFTER GAME IS IN PROGRESS. THIS FILE MIGHT BE CALLED 'STARMOD1.ASC'.
THE
OTHER MODULE, 'STARMOD2.ASC' WOULD CONTAIN EVERYTHING ELSE. THE LAST COMMAND
(TO BASIC) IN 'STARMOD1.ASC' WOULD BE: MERGE"STARMOD2.ASC". BOTH MODULES
WOULD
HAVE TO BE RENUMBERED IN SUCH A WAY THAT AT THE BEGINNING OF THE 'MERGE',
EACH
NEW LINE OF 'STARMOD2' WOULD WIPE OUT A LINE OF 'STARMOD1' WHICH HAD THE
SAME
LINE NUMBER (UNTIL EVERY LINE OF FIRST MODULE WAS OVERWRITTEN BY A NEW LINE
FROM SECOND MODULE). ONE CHANGE WOULD BE NECESSITATED IN THE SECOND MODULE:
IF
A PLAYER REPLIED 'Y' TO THE QUESTION, 'ANOTHER GAME ?' A BRANCH WOULD NEED
TO
BE MADE TO A LINE WITH THE FOLLOWING COMMAND, - RUN "STARMOD1.ASC". THIS
SOL-
UTION IS A BIT 'KLUGEY', BUT PERHAPS PREFERABLE TO FURTHER TRIMMING. SEE THE
'P.S.' BELOW; THE MICROSOFT MANUAL IMPLYS (BY NO PROHIBITION) THE LIKELIHOOD
OF SUCH (ABOVE-MENTIONED) ARTIFICES BEING EFFECTIVE. THE DISAPPOINTMENT THAT
MR. DOGGE ENCOUNTERED SHOULD BE ATTRIBUTED TO HONEST EXPERIMENTATION
COMBINED
WITH (THE TYPICALLY) INADEQUATE DOCUMENTATION.



HAVE FUN !!! - ZOSO


LATE NOTE:  THE EXPERIMENT WITH MERGING TWO OR MORE MODULES HAS BEEN TRIED.
I
AM SAD TO REPORT THAT THIS APPROACH APPARENTLY DOES NOT WORK. IT SEEMS THAT
THE EFFECT OF THE 'MERGE' FUNCTION IS TO DESTROY DATA (IN ADDITION TO
CERTAIN
LINE NUMBERS). MY THANKS TO MR. E. DOGGE FOR THIS INFO. E.D. ALSO SENT A
'TRIM-
JOB' OF 'BIGTREK' CALLED 'TREKMOD'; IT PLAYS THE SAME GAME, BUT LACKS THE
'SCO-
RING' AND 'VISUAL' FUNCTIONS. NOT TO DEMEAN MR. DOGGE'S EFFORT, I CAN'T PER-
SONALLY SEE HOW THIS PARTICULAR 'STARTREK' CAN BE MEANINGFUL WITHOUT THE
SCO-
RING ROUTINE. IF THIS WERE MY 'BABY', I WOULD (IF NECESSARY) REDUCE EVERY
BIT
OF (TEXTUAL) CONSOLE OUTPUT TO A 2 DIGIT CODE SO AS TO RETAIN 'SCORING'; THE
'VISUALS' ARE CUTE BUT NON-ESSENTIAL. SEE WHAT YOU THINK. ALSO !!! THERE ARE
(IN THE 'BIGTREK' FILES ONLY) SOME CRUCIAL ERROR TRAPS WHICH I INSERTED.
LOOK
FOR THESE AT THE BEGINNING OF THE 'NAVIGATE' AND 'IMPULSE' SUBROUTINES. THE
COMMON STARTREK PRACTISE OF INPUTTING A '0' WARP-FACTOR (DISTANCE) TO ABORT
AN IMPROPERLY ENTERED NAVIGATION ROUTINE WILL, WITHOUT THESE TRAPS, GIVE YOU
A 'SUBSCRIPT OUT OF BOUNDS' ERROR, AND THE GAME WILL HAVE BEEN (LITERALLY)
LOST. I SUGGEST COPYING THESE EXACTLY IF YOU WILL BE TRYING THE 'TREKMOD'
IM-
PLEMENTATION.

FWIW, the power supply looks too professional/commercial to be part of a 
prototype; it looks like it's meant to slide into its chassis/cabinet, with a 
handhold to allow pulling it out and a spring-loaded latch to lock it into 
place.

But it's also quite possible that the PS and the backplane don't even belong 
together.

Re: Any PDP11s for sale in the UK?

[Aaron Jackson via cctalk]

Maybe an 11/23, 34 or 73?

Thanks,

Aaron.
