Have VAX 82x0/83x0 console floppies been archived?

[Josh Dersch]

I also picked up a VAX 8350 today (it was a productive afternoon). It 
came with a box of maybe 40 RX50 floppies for console and various 
diagnostics.  A cursory Internet search didn't reveal whether these have 
been archived already.


If they haven't already been archived somewhere, I'll take care of 
archiving them later this week...


Thanks,
Josh

Any info on MTI 240 drive emulator?

[Josh Dersch]

Hi all --

I just picked up an interesting device, it appears to be a drive 
emulator that adapts DEC SDI to either ESDI or MFM drives (I would guess 
ESDI, but no real way to be sure.)  It's manufactured by "Micro 
Technology" and is labeled as an "MDI 240" on the front.  (On the rear 
as "SPEC.MDI-240", P/N "970176-000".)


Mine has no drives in it, just a power supply and two logic boards 
labeled "MSD13B" that connect to the drives.  I can't find much 
information about this unit at all, and just a bit about Micro 
Technology (apparently they were sued by DEC for building this device :)).


I'd like to be able to use this thing (possibly with my VAX 11/750).  
Anyone have any information hiding somewhere about it?


Thanks,
Josh

Only thing I managed to find so far:

Download and unzip that, then start at:
miatasg\dpws_aau\Service\Aaudpwssg.htm

DIGITAL Personal Workstation System Reference and Maintenance Guide

It's a collection of html pages, not a single pdf manual, and not
super friendly, but better than nothing.

Hi,

After meeting up with Kyle Owen at VCF-East today, and booting OS8 via
OS/8 Disk Server on his system, I have renewed interest in getting my 
pdp-8/e more functional.

Does anyone have an extra M8650 (KL8E) or M8655 (KL8JA) asynchronous
interface card they would be interested in selling or bartering?

The original database dump was available online fora while. That dates 
from ~2010 and has ~235 entries with URLs of the form:


  some-prefix.hp.com/legacysupport/

I checked a handful and none are there. Perhaps they've moved to a 
different URL but a cursory search provided nothing.


archive.org has at least some of those docs (e.g. 
https://web.archive.org/web/20050115202903/http://h18000.www1.hp.com/LEGACYSUPPORT/Digital/pdf/xl6.pdf) 
so all is not lost.


Additionally, manx often listed md5 checksums, which suggests that the 
docs have been downloaded and (hopefully) saved somewhere.


Given a mysql database dump, it would be straightfoward enough to check 
which docs still exist and which don't.

Although that manual appears to cover Pentium II workstations and if
the 433au is an Alpha workstation that manual is probably not the one
you actually want.

Thanks Dave.  The parts I studied seem quite clear (as expected).  I was 
thinking I might add IVprime support to DECnet/Python.  Maybe that's a bit 
silly, maybe not.  It clearly is valid to do so even if your interface isn't 
Token Ring, though I suspect it hasn't been done before.

What page are you looking at on Manx which has the broken link? Do you have

That title is a rather generic one to use for searching.

KY11-LB drawing error

[Noel Chiappa]

So, now that I have the 85S68 datasheet in hand, it turns out there's an error
in the KY11-LB drawings. (I just couldn't understand how the circuit could
possibly work, until I discovered that!)

On the two RAM chips (E11 and E27, used to hold the bus address, keypad data,
etc) the "Output Store" and "Output Disable" labels are reversed. (Not the pin
numbers, etc - just the labels.) I.e. 'Output Store' is actually pin 13; it is
tied high (as shown on the drawings for that pin).

I have 'fixed' a copy of that page from the print set, and will (soon) issue
an updated PDF.

There's the T11 Users Manual, and the T11 Evaluation Module Users Guide:

Nothing about Fluke pods, but maybe something more than you have at the moment?

Best of luck

I've been looking at the T11 and I mostly just need to trick a Fluke pod 
into doing most of the T11 control, Address and Data lines so I can 
exercise the RAM and ROM attached to it. I will be experimenting with a 
8086 POD as is has multiplexed Address and Data lines (0 - 15) as well.


Of course there is a T11 adapter for the Arduino CPU test project on 
Github, I am getting that as the T11 test is written for the Atari 
System 2...
