How do you think I got to be like this? :-)

You don't want to know how many ST506s, ST412s, St225s and D540s I have
around here doing not much. And they are all good!

And you have to know that little detail beforhand. Then there is the
matter of formatting as some can't (require the disk to be formatted else
where) and some require special software if they can.

Hey, are these Apollos the ones with the *GIANT* SMD disk units?
The ones I saw were *HUGE* 9" CDC's that had been refurbed by
Seagate! They were mounted in a big tray (kinda like a SABRE,
but bigger), with a powersupply, and some controller electronix.
This whole mess was about a foot square, by maybe 2 feet deep.
DOes that sound like it?

Yes, the VS2000 format (and RCT table) is compatible with the RQDX3. You
can do the formatting on the RQDX3 as well, with the right diagnostics.
Of course, there are also machines with floppy drive systems that cannot do
a low-level format. The most classic 8" floppy drive systems (specifically,
the IBM 3740) can't format floppies, for example. There are also 5.25"
floppy drive systems that can't format - for example, the RX50 on a DEC
Q-bus or Unibus controller. (On some Rainbows, it is possible to low-level
format RX50 media directly.)

Hi!
At the moment I’m rather an unhappy user of an old PS/2 laptop computer. Why
unhappy? I’m not able to boot it up, alltrough i tried everything, started
>from disassembling it to the smallest part to changing the 3,5” floppy disk
drive and so on. I would really appreciate any information or hint about
starting it up. O.k, these are the specs of the machine:
Machine: IBM PS/2 Model L40 SX
Proc.: i386DX @ 20 Mhz
RAM: 2 Mb on-board
(the two blue memory slots are still free)
HDD: 60 Mb (Conner, Model CP2067, no OS on it)
FDD: 3,5” 1.44 Mb
(Panasonic, Model JU-237A03W, P/N 72X6074) < !
The problem is that the FDD activity LED does not light up when the computer
is started, even when a disk is in the drive. Only the LCD symbol of the
3,5” disk drive on the computer panel goes on, but nothing happens. I never
had the chance to work on PS/2 computers and so I don’t know what to do now.
I’ve checked all connections and all cables. It seem like the FDD doesn’t
get any power input from the board, but i’m not sure. I think that the
problem is somewhere else. Later when the BIOS tries to boot up from the
hard disk, a message in Danish appears telling that the command interpreter
(COMMAND.COM) couldn’t be found … (The computer has a Danish BIOS on-board).
Please help me, I need help as soon as possible. Mail all hints and/or
advices to evilnet_genesis(a)yahoo.com or evilnet_genesis(a)hotmail.com. If
nobody can’t help me then please give me some links or adresses, where I can
find informations.
Thank you!

The HP 3000/70 is a stack-based CISC machine that runs MPE. No, it can't
run any version of Linux or anything else. It's about 6' wide, 4'high, 2' deep.
It dates back to about 1983 or so.
BTW, I thought I had the TM on "Mr. Sledgehammer", see:

They are. Two are optional BASIC and the other is optional Assembler.

Hi Chuck and all
I've posted some pictures of the NCR core memory that I have
on http://ccii.dockside.co.za/~wrm/ccc/index.html. There's
also a picture of a PC network card (large thing with a Z80
on) that I'd like to identify.

These 24 pin chips sound to me like ROM's.

Tim:
Thank you so much for this, and the earlier, message regarding
the RS11. I will look into my handbooks, though I must admit to
having only a few (like three) such manuals, and in them I have not
found descriptions of all the hardware that I have to date obtained.
