The micropolos and NorthStar controllers and matching drives were common.
Most any s100 floppy or hard disk system could be used if:
=The controller would work well with a 2mhz 8080 (some DD controllers
would not).
=the controller fit in the available slots (there were only a few)
=The controller didn't use too much power
=The drive had their own power supply

The North Star setup was pretty common on the SOL. I have CP/M set up for
the SOL with a North Star disk system. You'd need a North Star controller
board, and any standard external 5 1/4" drive.

Some of the drives that I've seen actually have the connectors extending
out, as if they're on a seperate piece of equipment alltogether. Now,
anyone know about what type of power connector (small, like on a 1.44MB
floppy, large, like on normal HDDs, or non-standard?) Also, is there any
way to make a 44-pin connector into a 40-pin connector (for a standard
dekstop?) Also, I've gotten into the whole mini-PC idea. So, I want to
build one. The hard drive'll probably end up being a Kittyhawk, I'm
currently thinking an x86 CPU (as little power and size as possible. I know
that the AMD Elan 400 COULD work but I haven't seen them resold, and I'd
need drivers for the built in stuff, etc.) So, if anyone has any info on
this, I'd love for them to contact me personally. (If they could put
"Building a Mini-PC" or something in the subject, so I could know that it
wasn't a ClassicCmp post...)
TIA,
Tim D. Hotze

<SurplusDirect (www.surplusdirect.com) had some 40mb PCMCIA hard drives o

I don't have data on PCMCIA and removable is not a requirement. I will
look at them if I can find data on the interconnect as it's not going into
a PC.

<3.5"? That's a "standard" off-the-shelf IDE disk, isn't it? 2.5" is
<a standard off-the-shelf laptop IDE drive. 1.8" drives are also
I'd rather 2.5 or smaller but a really cheap 3.5 is ok.
<Are you looking for drives that are still produced in quantity? If not,
<the Kittyhawk 20MB drive would be a good one to get (at the website
<mentioned previously).
The is at most a one up for myself(non commercial design).
Allison
The Kittyhawk is pretty small, and I don't know of any machine other tha
<the Dauphin DTR-1 what used it. I don't think it's the smallest though.

As someone building a smaller z280/cpm system I'm in the hunt for a
IDE hard disk with a form factor 3.5" or smaller. I may be able to use
PCMCIA but a forsee them as too expensive. The storage can be small as
10mb and anything over 60-80mb is gross overkill(I'll take bigger but I
really dont need it). My other requirements is known good and real
cheap.
Allison
I have acquired an old "kit" computer, circa 1977. The CPU has a trademark like a double script N, slanted to the right, with one superimposed on the other. Most of the other 10 or so smaller chips have the same mark.
Adjacent to this is the number 804 (the CPU ID?) Other numbers are ISP-8A, /500D and SC/MP.
It is the size and shape of a Z80 or 8085
Anyone have any idea what this is?
Thanks
Hans
PCMCIA drives are 2"W x 3 1/4"L x 3/8"H.
Note that the SyQuest media size doesn't really count because the rest of
the drive was in the PCMCIA card (heads, motor, electronics).
I have a DTR-1 also, BTW...

I finally got the various pieces together that I need to hopefully setup
a shoebox for my 3/50. I have a copy of NetBSD on CD-ROM, the shoebox, and
60mb tapes.
My question is this: what is the best way to setup the shoebox with
NetBSD? I thought about hooking the shoebox and a CD up to a PeeCee and
trying to create a bootable tape (I don't know if this is even possible), or
copying the 68k distribution to the hard disk. If you read the FAQ on the
CD, it almost sounds like you need a bootable system to be able to install
it.
Any thoughts??

Hi,
I have a Sun 2/120 (actually a Computervision manufactured clone) that I
don't have room for. Condition is unknown, but it does have keyboard,
mouse, monitor and a few spare multibus boards. It is big and heavy, so
collection from Cambridge UK is preferred but I would consider
delivering to a location not that far from me.
