There is a program called Apple Drive Setup SC or something to that effect
which will format and prep 'apple' hard drives. (they rigged it so if the
drive does not have an apple ROM it won't format it) but there are ways around
that, check out:

Neither the Mac 800k format is done with a variable speed drive and is
practically impossible to emulate in software (PC users can get around this by
adding a Copy II PC option Board which bypasses the drive's controller for
better flexibility.)
My suggestion is to see if you can get a set of SE Superdrive ROMs and a 1.4HD
drive for your SE then you can use 1.44 meg disks which CAN be read on a PC
(Via MacChette) and also can read PC disks on the Mac (Via Apple File
Exchange). :)

It was the ICOM via pertec purchase and integrated into the altair line.

This is probably not a 10yr thing, but I don't know any other list that's
got this many people that know what they're talking about...
I've got a Wyse WY-50 terminal. From the menus, it's got four modes:
FDX, BLOCK, HDX, H-BLK
After reading (on this list) that the old HP terminals had something
called "block mode", I was wondering what it meant here. Also, what's FDX
and HDX? The first thing that came to my mind was Full Duplex and Half
Duplex, but I don't know how those would apply.
Also, are these terminals just really lacking features or are Linux and
*BSD just not running it right? It seems that tabs get ignored, for one.
And it is just generally awkward looking. (And the arrow keys don't work
in pine, but that's not terribly critical.) It doesn't act in a logical
way at times.
What were these terminals meant to be used with? I got this one from a
AS/400 installation, though I don't know if it was ever actually used for
the AS/400 (they had a whole mess of IBM twin-ax terminals for that).

Hi Again,
The Sun currently has 2x Fujitsu M2322K drives which appear to be SMD
interface drives (on a xylogics 451 controller), is there any way to
interface ohter kinds of drives into this interface?
Also, I spotted an Apple IIGS for sale in a second-hand place down here,
it looked complete but it was labelled "parts only". I asked why and the
response was "It doesn't have a startup card", I assume this means disk.
They want AUS$60 for it, I was thinking about offering them AUS$30, is
this reasonable?
Cheers
Karl

You can use a Commodore 64 power supply on your plus/4 too!
What you need to do is remove the power connector from a dead 64 motherboard
and solder it into where the the Plus/4's power connector is. Fortunately
they are both pin for pin compatible with each other. I have modified one
plus/4 in that way and haven't had a problem since. ;)

I have a really compact "PDP-11/23S" chassis that has an 18-bit Q-Bus
backplane (4xQuad) in it. Although the circuitry for the Q-Bus is on
traces of a PC card, there are also wirewrap pins extending out from
the backplane. Am I naive to assume that I can convert this to a
22-bit Q-Bus by wirewrapping four or so lines? Any pointers on how to
do this or on technique?
Thanks,
Dave
Hello List:
I have some interlinked questions for the Assembled Gurus:
I am trying to understand device adressing in the system as a
whole.. is there a good 'base/vector addr for dummies' document I
could be pointed at? I have looked (sunsite, etc) and I'm still
missing something. I *did* find out how to find the backplane jumper
to be removed when installing the RL11... after I discovered it, I
notice some kind soul put a red sleeve on the CA1 pin on each of the
slots....
Am I correct to assume that RL02s and RK05s can coexist and
co-operate in the same system?
I am trying to construct a 'fully loaded' PDP11 system, and I want
to have the entire range of peripherals available, so that I can
perform media and format conversion, as well as have fun running the
thing.
Will one system support the RX02, 9trk, RL02, RK05, DECTAPE, Paper
Tape, consoles and a few terminals, and maybe an Ethernet adapter? I
realize this will take a one or two expansion chassis... but am I
getting overly ambitious for one CPU? Should there be, maybe, two
closely-coupled '11s sharing the load?
Eventually I am aiming for a VAX 11/750. Would it be 'better' to
wait and use it's resources, whatever they might be?
I want to spend a little less time maintaining and a little more
time computing... and I'm dying to run some of the DECUS stuff on my
Machine.
Thanks So Much (in advance)
Cheers
John
I have just colleected a PDP-11/40 which is said to be working apart from
the fact that the PSU has been removed. If I can find a PSU in the future
then this will be my first 'lights and switches' machine.
I was also given 2 Apple ][ s - 1 ][e and 1 ][Eurostar There is a disk
drive with them, but I see from the notice on the back of the drive that
it is supposed to be connected to an interface card. As they have no
cards in them I suppose I will have to wait until I can scrounge one.
Regards
Pete
Hiya List:
In the process of consolidating/thinning down my out-of-control
collection, I think I will place my 11/04 system up for adoption.
It is: 11/04 w/operator's console
7266 CPU
8265 CPU
MOSTEK memory bd, 8001-H-00, unk (8K?)
Plessey mem bd marked 64K depop to 48K
7856 SLU/RTC
7846 RX11
Plessey DMA? (can't remove w/out getting behind rack.)
ACT Quad serial I/O unit.
Plessey disk controller set and backplane (in seperate BA11 which
I'm keeping to use later..)
RX01 dual 8" floppy
(2 ea) CDC Cealus (Ceali?) top-loading drives, accept RL02 packs
(and probably are the same as RL02s) Plessey badged.
Battery back-up unit H775A
A load of cables, mebbe spare boards, engineering printsets, etc.
I am also retaining the DEC rack it's in.
I have had this machine partially on the air... it boots into ODT
at the console, but I've never tried to boot from the big drives or
the floppy. (This machine was removed from service and stored until
I bought it, so it *used* to all work... it's not a mongrel system.)
THE DEAL: I'm in Southern California. (Malibu). I am looking for a
formatter card to use a standard 9-trk drive in a PDP-11/34a system,
as well as the inteface card(s) to hook up my big System Industries
drive to the '34A. I will disassemble and deliver the above items
within a reasonable weekend day's drive, in return for the two
devices mentioned (or at LEAST the tape card.) [Other gear related to
PDP storage or any MINC stuff will be considered, too..]
If, in two or three weeks, there is no response, I will GIVE the
11/04 system to the person who, IMHO, wants it in the worst way, ie.
whining, importuning, pleading, tantrums, etc. will be
considered..... BUT! given that scenario, you must come and pick it
up and cart it off.
This is a good 'starter' machine for someone (hopefully) on the
list who wants to get going in PDP-land.
Note to the adventureous: the combined weight is about 500lb...
shipping ain't an option.......
Cheers
John

Hmm...why not? I've read that the iCom floppy disk controller
was the first 5.25" disk controller for S-100. Not sure if
that's true though.
