I have some experience/documentation on the Draftmaster II,
if it would be of any assistance to you.

A few weeks ago, I got a rather nice PDP-11/34 (34A, turnkey front panel)
>from a scrap yard. They had two identical systems being used in some sort of
electronic testing devices. I only got one system because the other one
looked like it had been hit by a forklift a couple times. It wasn't in great
shape, so I salvaged some cards from it (CPU, memory, DELUA, drive
controller, UNIBUS utility stuff...).
My system is in very nice shape though. And along with the CPU, I also got
two RC25 drives, along with controllers and cables. I've never seen these
before. Can anyone tell me anything about them? They look like nice drives,
but I've never really heard much about them.
Anyway, this will be my third 11/34. Of the other two, I still have (and
very much like) one, and one has been passed on to another list member.
Anyway, more questions on recent acquisitions to come shortly, I'm sure.

This is from the Intellivision newsletter:
INTELLIVISION LORE FROM THE FILES OF THE BLUE SKY RANGERS: THE INTV PC-XT
COMPUTER
Most Intellivision buffs are familiar with the three attempts Mattel
Electronics made at producing a home computer: the Intellivision Keyboard
Component, the Entertainment Computer System (ECS), and the Aquarius Home
Computer System. Less well known is INTV Corp.'s foray into the computer
business: the INTV-PC/XT.
Sold only through a 1986 brochure to those on the Intellivision catalog
mailing list, the computer was touted as "From the makers of Intellivision
...a name you know. We've been around awhile. We manufacture Intellivision,
which brought a new standard of quality to home computer games in 1979.
The INTV-PC/XT does the same for personal computers today."
The brochure featured a half-dozen cartoons by Blue Sky Ranger Keith
Robinson (TRON Solar Sailer) of average people using the computer to better
their lives.
The INTV-PC/XT sold for $999.95 plus $25.00 shipping and handling. It had
switchable clock speeds: 4.7 MHz (same as the original IBM-PC) and 8 MHz.
It came with 640K RAM, IBM PC-DOS, a monochrome monitor, and two 5.25"
floppy disk drives.
In reality, the computer was simply another of the nearly identical
IBM-compatibles that a dozen generic companies were selling in the mid-1980s.
INTV didn't manufacture it, they just put their label on it.
The brochure - and the use of "XT" in the name of the computer - were a
bit misleading. The brochure claimed that "the INTV-PC/XT is a true
IBM-PC/XT compatible." Since the IBM-PC/XT (unlike the IBM-PC) came with
a built-in hard drive, it could be inferred that the INTV-PC/XT also came
with a hard drive. It didn't.
In 1986, over 300,000 people were on the Intellivision mailing list. How
many bought an INTV-PC/XT? We don't really know. If any of you out there
owned one, we'd love to hear from you!

Hey, guys.
I'm having trouble turning up information on the old Bernoulli 10 MB
drives---the ones that used 8" media---that isn't mostly rumor and
innuendo. Anybody want to take a stab at positively confirming or denying
any or all of the following?
1) The Bernoulli 10+10 uses a custom interface. I need the correct
controller card for my PC (or better, my Mac).
2) The Bernoulli 10+10 uses a SASI interface. I still need the correct
controller card for my PC (or better, my Mac).
3) The Bernoulli 10+10 will work on any classic SCSI controller. I need
the correct cable magic. (Describing the correct cable magic earns bonus
points)
Thanks

Tony,
That's the bugger! You just gave me the clue: one of my pdp-15s had the
power supply for the XVM-15 memory box robbed before I got it; 'they' wanted
to keep it for spares for pdp-11s. (It used the same 'black box' regulator
bricks).
Getting the -15 running was a higher priority that keeping my 11/35 intact,
so I 'sacrificed' the power supply from my 11/35 to power the pdp-15 memory.
The remains of the old 11/35 chassis must be lurking in a corner, that's why
I couldn't find it.
This is good news, it means I'll be able to build a 10.5" 11/35 (which is
what I want) out of the chassis of the 11/34 I just bought on ePay... :-) I
had no idea if the chassis/PSU was even vaguely similar... memory failing!
I will of course pay due attention to the regulators required.
Thanks to all who replied
Mike
