I'm trying to find a reasonable IBM 8525 all-in-one system. I've seen
the ones on ebay ($200! before shipping, for a computer from the late
1980s that were in high abundance) if anybody knows where I could get
one reasonably (preferrably close to illinois) please let me know,
thanks! picture: http://www.recycledgoods.com/images/s_p_20127_1.jpg
For small pulleys, check out a hobby shop that deals in radio controlled model airplanes and cars. For small gears, try www.nwsl.com. They also have small drills, bolts, and metal rods (e.g., 1.5mm x 6"). In England, try http://www.ultrascale.co.uk/ for small gears.
See the following forwarded message. If you're interested then contact me
and I'll pass on the e-mail address. I don't want to expose it to the
world which is why I'm expunging it in this posting.

Subject: amiga 1000 computer
Hi: My name is Joan Curtis. I live in Huntsville, Ont. Canada. I have
an Amiga 1000 computer in original box with a compatible printer (Star
NX-10) in original box. Plus I have Books -User Guides -(Binder) Book -
Amiga Enhancer Software Featuring Amiga Dos Version 1.2 Kickstart 1.2
Extras 1.2 Includes Revised Amiga Basic and PC Utilities. Also the book -
Amiga Dos Inside and Out. Also a book - An in-depth guide to Amiga Dos
and the CLI. I also have Magazines - Creative Computing 1985 - Commodore
Business and Amiga User 1986 - Amiga World 1987 - Amiga World 1988 - Amiga
Users Guide 1989 - Amiga +Plus 1990. I also have 7 games - Sky Fox - Rogue
- Hardball - Borrowed Time - Mind Shadow - The Faery Tale Adventure - and
Dejavu. There are also 43 discs with case to hold them. I saw an article
in the Toronto Star in Feb. 16, 2003. Would like to sell this collection,
but do not know how to go about it.

I have 3 3.5" floppy drives with configuration jumpers (and 5 times
as many without :-) ).
Ons is a Chinon FZ-357, and has jumpers for: MD, RDY, MM, DC, and
Another is a TEAC FD-235HF and has jumpers for: H HO, OP, LHI, HHI,
and a position (but no header pins) for FG.
The last is a Sony MPF520-1 which has 2 rows of 3 pins... and I have
no idea what they are for.
I understand some abbreviations... RDY (ready), DC (disk change),
but not MD, MM, TTL/C-MOS (assuming this is for interface logic
levels?), and the TEAC ones I don't know at all.
The Sony one is a mystery, and a google search hasn't turned
anything up... don't know if the headers are for selecting D0-D3
only... or more than that.
Can someone fill me in/point me to web pages on these 'magic' jumpers
for these drives ?
One again, I'm getting the grumbles over Ebay's policies: its impenetrable
policies on how much much I pay for what, lack of protection against
insane buyers, a constantly changing look and feel, and so on. I tried
out chasethechuckwagon.com for selling a couple video game carts and I
like it. Their whole fee structure is generous and easily explained in
one paragraph. The only problem is that I don't sell that much in the way
of video games. I don't know what a good alternative for classic computer
stuff would be. Right now I'm looking closely at ebid. I think this week
I'll run a few things there and see what happens.

If I needed to go from IDE to MFM I'd go to my junk box and pull out a
WD1003 (or one of the smaller versions) and fake the interface of
IDE to ISA16. The two are so close its only the matter of the
IO address lines to resolve them down to CS1 and CS2. Command wise
the 1003 was the prototype for IDE command set.
During cleanup I found 3 unused RK06 heads, Dec partno 74-14130-12.
They are still in their original box.
Next to that I have a few more RK06 heads, new, but not in a box,
as well as 3 or 4 RK06 servo track heads (these have an extra
cable + connector). Maybe this is Dec partno 74-14130-13 ?
Make me an offer.
I've been trying (unsucessfully) to get various flat screen
monitors to display the output from a sun monochrome frame
buffer. This is proving tricky.
The monochrome fb outputs 1152x900 if I recall correctly and
its proving difficult to get any monitor to sync to this. Note
the output is analogue not the older ECL (?) type display.
Old CRT multi-sync monitors that sync on green handle this
Can anyone recommend a modern flat screen that will work with
this kind of framebuffer?
I do have various video processing units that can scale and
process the output, but I'd rather not use these as they
are already in use for other tasks.
