I obtained a Data I/O 2900 programmer at Dayton in rather grotty but
serviceable shape. But it is missing it's little old floppy (the
disk, not the drive). The Data I/O website is silent on this.
Anyone know where to find one?
Also, to add to Ethan's Dayton report: I saw several Ultra 1s
[one going for $5 at the end of Saturday] but no DEC, No SGI
and certainly no Xerox Altos.
This, my friends, is truly, truly hilarious and awesome...

Anyone got some space and 3 phase ?
Browsing Wappingers Falls, NY, USA salvation army today and walked past an
Apple Performa 6115 and an Apple PowerPC 7200/120 with 10/100 Ethernet
add-on card! Both work and there is an Apple 14" monitor, keyboard and
video cable adapter too. Talked to the manager lady and she said she'd let
it all go for $14.99 US. I don't do Apples too much and don't have the
money to spend, but if anyone in the area wants em, they are still available.

Just wanted to say thanks for the people who have contributed knowledgebase
articles to the classiccmp knowledgebase (www.classiccmp.org/kb)
I do know that one person here is working on a really good article, should
show up there soon!
So, who wants to spearhead putting in a short knowledgebase article about
hooking HP-IB devices, given the recent discussion :>

And they did put effort into front-end terminal concentrators on the
models of those systems.
TOPS-10 had a significant influence on the user interfaces of some of
smaller operating systems (RT-11 and RSTS for example), as well as CP/M.
Google for discussions on alt.sys.pdp10 for why this wasn't true for
RSX and VMS.
I suspect that the driving force for tools (esp in TOPS-10) inside DEC
because much of the software development inside of DEC for other CPU
they converted to VAXen was done using cross-development tools on their
timesharing systems (MACY11, etc.) and because 10's were THE machines
to have in
universities (MIT, CMU, etc, etc) if you wanted something that had a
lot of good
tools for a moderate amount of money.
Well, I have good news and I have good news... (and just a little bad news)...
I have now erased a bajangle of eproms, I have quite a few Basics burned
and lots of spare blank carts, so they'll hit the mail soon. I have
tomorrow off, so I'll prolly pack/address/ship then. If not, definitely
over the weekend. Tuesday nite was going to be my "Pack'em up nite" but the
wifeypoo got a line on a good job, so it was transformed into "Rewrite the
Resume nite." Wednesdays are a PITA for me (to work at 7:30am, get out
at 8:30 pm or later) so I rarely feel like doing anything after work. Of
course, my LCD monitor "went blank" Tuesday nite, so I had to figure out
the cause of that last nite... I was a grumpy dude by 11:00 pm. ;-) Turns
out the LCD monitor died... :-( I grabbed my wife's monitor and am using
that temporarily until I can get a new one in.
I did test a basic cart in my HHC, and it seems to work fine, *except* I
think my RAM's a bit wonky, as once I create a program, then exit BASIC, it
thinks I have 2 bytes of free memory left. Weird. It might also be a
limitation as to *which slot* the chip goes into - I didn't diddle with
that. Or... I don't believe that the internal batteries are functioning, so
it might be a power problem causing the wonkeyness... Anyway, the Basic
itself comes up and it takes immediate commands just fine, and I've entered
in 2-3 line programs that run fine until you exit basic, then it thinks
there's no free memory left. Like I said, weird.
Anyway, I'll send out individual emails tomorrow with the status of each
order, but I wanted to let everyone know I didn't forget 'em!

I'm trying to repair the tape drive in an HP 9825. The roller has melted
(no surprise there). It seems like I could just get a bit of silicon
tubing or something that has the same diameter and guage as the existing
I know this has been discussed before but I can't find any specific
messages (by the way, the CC archive search is broken, Jay). Can anyone
provide any tips or guidance so I don't have to re-learn mistakes already
Any tips for cleaning off the existing material? Isopropyl alcohol? Any
thoughts of using heatshrink tubing and applying multiple layers until it
has the same thickness as the original roller?
Thanks for any help. This will be a candidate for adding to the knowledge
base once I've successfully replaced the roller.

Since the 380Z seems to be popular at the moment, does anyone have info
on 2 bits that are not properly described in the Information File?
The first is the dual cassette controller. The pinout of the 7 pin
cassette socket is given, as of course is the schematic of the VDU board
that contains the cassette circuitry. The controller seems to contain a
couple of relays to control the recorders (were these powered from the
system 5V line or a separate power supply?) and switching to allow either
one recorder to be used, or two with one used for recording the other for
playback. It's possible to make some guesses as to how it was wired, but
some real details would be nice
The second is the SIO-2 board. This was a bit-banged serial port using,
IIRC, 3 lines of the user port. 2 ouput lines for TxD and thr reader
control relay, one input for RxD. At least knowing what port bits were
used would be a help...
