I am playing around right now with a Tandy 2000, but it has no floppy drive. THE
HD works fine, but I'd love to get the information off the HD, and that is
difficult right now :). I tried a couple of standard 360K/1.2MB drives before
Googling around. Does anyone have any information about what can be used as a
replacement drive?
Interestingly, the information I've seen indicates that the Tandy 2000 runs a
modified version of MS-DOS 2.11 but the version on this machine is 2.0.
I'm picking different pieces of various leftover /34 systems to make mine. I
have a question about the regulators in the back of the /34's ba11k.
Exactly what regulators are required as a minimum for a /34 that is just a
dd11-pk with no expansion? Assume just a processor, one memory board, RL11
controller, one DL11W... nothing heavy. I have one ba11 with regulators in 4
positions and one with regulators in positions 1-3. However, one had a RK11D
which I'm removing, one had a DD11-DK addition which I won't be using... and
I would prefer to remove regulators that won't be used so they can sit on a
shelf as spares and not be powered up all the time.
I've looked in the 11/34 user manual as well as the ba11k technical manual
and I can't seem to put together this info. Can someone point me in the
right direction?

Aha. Now that makes sense! Thank you :)
What that means to me then is that in the /34 the 9302 should only be
plugged in to a the AB unibus out slot and NOT in a MUD slot, otherwise, you
get a funny smell I bet :)
So what about the 9312 in the /34 then. I assume it can only (no matter HOW
it's jumpered) be put in a MUD (AB) slot, never in an AB unibus slot (Unibus
in or Unibus Out). ??
Then, this of course brings me back to my dearly beloved (sarcasm) /45. In
that machine, the cpu doesn't terminate anything from what I understand,
hence the 930 at the front in slot 1AB. I assume in the /45 then, you CAN
put the (appropriately jumpered) 9312 in the last slot (unibus out), and
that you don't put another 930 in that slot and put the 9312 in a prior AB
slot. Is that all correct?
Thanks so much!

actually we are both wrong, the macro was used to make the call external if needed. The near declaration was required to tell the assembler what addressing to use. If the label was in the module being assembled, then the assembler knew what size to use.

Hi,
I posted this to the rescue list but have had no response :<
So, I'll try again, here...
------
I've been trying to move my various peripherals into
611-type cases. Hopefully, get things a bit better
organized.
These stack nicely with ~12" (WIDE SCSI) cables to
daisy chain from the OUT of one to the IN of the next.
But, some *other* cases aren't quite as well-behaved.
For example, stacking anything atop a 711 case requires
a slightly longer cable to tether the 711 to the 611.
Likewise, a 622 (?) needs a "cable stretcher" to span
the gap to an adjacent 711/611/etc.
Did Sun make *slightly* longer wide cables? Like 18"?
Obviously, I want to use short cables to keep the chain
as short as possible...
And, can anyone suggest a good source for the ~12"
and similar cables?
Is there anything else I should be wary of?
Thanks!

Okay, I got curious to see if he was selling anything. Checking all of his
listings going back to those that closed a month ago, not a single item has been
sold. This starts to restore my faith in the human race again :). I didn't check
to see if they had a website and if they are using Ebay as inexpensive
advertising to divert people to their website.

I found some interesting things to buy, but then saw the prices... not only
are they ASTRONOMICAL but the seller lists almost every item, even ordinary
keyboards, as "Very Rare"... I wanted a Canon X-07 and a Toshiba T100 but he
posted them at $299 and $399 respectively. What the hell!?!?!?
My lord, that's a HUGE wad of code for something as simple as
MS-DOS... How the HECK can an OS that fits on a floppy with room to
spare have 20 megs of ASM source. Does the wad include the tools that
M$ ripped off like Doublespace and the like?
