Ok you DEC-heads. What baud rate does the Digital DF02 modem jog along
at?

Hi. I just got a shwrink wrapped copy of this, and wanted to know if anyone
wanted it before I used it...
I'll either sell it or trade it for PC/Apple ][ stuff.
Ciao,

Sorry... By "Mac II-type" I meant that size mb. Both that I have use real
Apple motherboards. One is (iirc) a Mac IIx, the other is a IIfx. Very
nice servers for their time, with great cases.

RT-11 has always been 6.3, RSX-11 is 9.3 IIRC, and UNIX doesn't have any
fixed format - though early versions had a fairly small limit on name
length (12 chars?). All versions of UNIX allow as many dots as you can fit
in the length.

@Get this for humor. The funny thing is, he'll probably get this price
for it!

Hi. Just heard about this, so I dunno really what I'm talking about...
Appearantly, this company is (was) selling liscences for DOS 3.3. I'm
guessing that this is from a deal with MS. Has anyone ever seen this? Is
it available with another product, such as early Windows releases?
Ciao,

OK, to aviod confusion the first system in question is a SMS-1000, with a
PDP-11/73 board, 2MW RAM, RL02 Controller (DL), TK50 Controller (MU), Dilog
DQ606 Floppy Controller (DY). The SMS-1000 has an internal Floppy and HD,
which it thinks are a RD51 (DU) and RX50 (DU). The boot ROMs support DU
(DSA, the HD and Floppy), MU (TK50), and MS (TS).
I'm able to boot off of RL02 by entering in the bootstrap from ODT.
I've got RSX-11M and XXDP RL02 packs, and can boot from either. I've
managed to make a bootable XXDP floppy diskette. I can boot the machine
directly off of the XXDP floppy on power up. I can boot the XXDP floppy
>from the XXDP RL02 pack, and then boot the XXDP RL02 pack from floppy.
However, if I power up and boot from floppy, I can not boot the XXDP RL02
pack. Is this because the Boot ROMs don't support RL02's?
Does anyone have any instructions for a Dilog DQ606 controller? I gather
that it can be configured to act as several different floppy drives. The
drives that came with it are labeled as being a RX-50 and a RX-33, yet
RSX-11M sees both as RX-02's. I'd like to get these changed back to RX-50
and RX-33.
What does the device name 'MS', device type 'TS' stand for? My guess is a
9-Track tape drive.
I've also got a PDP-11/44 that I'm slowly working on restoring. It's in
two racks, one has a pair of RL02's which have been cleaned up. The other
has the CPU, 2 RX-02's, 2 TU-58's, and a battery backup. In looking at the
CPU, it looks as if it has a LED for the battery backup. Does that battery
need to be in the system? I would just as soon remove them and not have
anything to do with them since they are old lead-acid batteries, and I'm
not very fond of such things (spent 3 1/2 years of my time in the Navy
working on UPS's). Is there any reason that I can't just plug the whole
thing into a power source outside of the rack. I'm asking since for all I
know the battery and powersuppy in the bottom of the rack are some kind of
power conditioning circuit.
Also does anyone have any recommendations on how to go about testing out
the power supplies on the 11/44? I'd just as soon not blow anything up. I
have powered up the RL02's, but that is all so far. I'm waiting to test
the power supplies before I get the remaining boards that I need for the
system.
Thanks,
Zane

Hey, not to mention those guys that unpackage their CoCo III's and put them
into PeeCee cabinets to add SCSI, more disk drives, extra memory, etc. etc.
etc.

I'm trying my darndest not to get too involved in this thread, even though
I started it, but I need to set the record straight: The URLs I sent
weren't from ebay, they were from Haggle Online. An online auction that is
totally free to buyers and sellers, unlike ebay, that charges a fee to
sellers. Not that it really matters, since online auctions seem to be the
new "great satan" on this list. I would like to point out though that if
you don't know the true value of an item, why not let the public decide?
What's wrong with making a little bit of money off a hobby? I know this
probably isn't over, but I'll try to stay out of it, regardless.

The smallest I've seen run on 8080 and fits in some 100 or so bytes. It
was published in Kilobaud April 1978 page 102 and yes it was real.
To multitask on most anything all you need is an interrupt and save the
context of the current task and start some new task... the order, where
the tasks are and memory allocation can be somewhat tricky but, for
small tasks its pretty trivial. I've done it in 8048 MCUs where the
resources were 64byts of ram and 1k of rom and the tasks were keyscan,
display, serial IO and code conversion. The timer provided the
interrupt.
