I think I've got that one as well as the 2Mb/sec follow-on one in my
hellbox. IIRC, it sets the DMA/port/IRQ via the ISA-PNP mechanism
(which accounts for the extra logic). If you've got an ISA PNP
inventory program, you can easily verify this. An early version of
PNP, but later ISA-equipped PCs support it via BIOS and there is
usually some sort of manual configuration program for those that
don't.
Otherwise, it's pretty much a garden-variety floppy controller,
though I don't recall if all of the ancillary signals are brought out
to the connector (e.g., DISK CHANGE).
Depending on the exact date code and stepping of the 82077, the card
may or may not support writing FM-encoded data.

I think that they are out of business.. One of there competitors had a
note on their web site to the effect that since needhams is out of
business, they will give a trade in to their programmer. I have not
been able to get on the Needhams page for 6 months or more.

This discussion of chip programmers prompted me to try yet again to find
something useful for programming chips using Linux. I found the software
info page at www.willem.org which states that the DOS version of the
controlling software is kept current. Now, suppose we run FreeDOS on a
tiny x86 board talking out the rs232 port...

Do you happen to know where I can locate one of these drives?

I'm looking at buying a Willem programmer to go with my Data I/O 29B.
Mostly I'll be using it for reading existing ROMs and programming
stuff bigger than the 29B can handle.
I've been looking at willem.org, on eBay, and at a couple of non-eBay
sources. The first most obvious problem is that none of the available
variants exactly match the willem.org board revisions, and I haven't
found any cross-reference information.
I'm probably not going for the new "true-USB" board. Any system I'll
run it with has parallel ports.
So...
1) I know a few folks on the list have willem boards. What board
version do you have, where did you get it (if you remember), and are
there any major pros and cons?
2) Does anybody here have experience with Kee Electronics?
http://www.keeelectronics.com/
I'd rather buy direct than off eBay, and they look like a good
product line.
3) Yes, I know the software's Windows-only. If anybody knows of a
sub-$100 programmer with OS X software, I'd be overjoyed to hear about
it. Otherwise, BFD; I have to keep a Windows box for work anyhow.
Any input is greatly appreciated.
Zane, I'm still getting a 554 reject from citrine.aracnet.com

Hello,
I'm looking for an older version of Ontrack Disk Manager. I need to perform a bad sector check and low-level format for an MFM HD. I actually have 2 legit copies of the program (from the late 1980's), but, of course, I cannot find them now.
Thank you,

Watching a few of the [E]EPROM programmer threads got me to thinking about
my EMP-30, made by Needham Electronics. I have not been able to get their
website to come up for months. Anyone know if they have gone out of
business? I noticed that prices for their programmer accessories (e.g.
family modules) jumped substantially a few years ago which is usually not
a good sign.
If they are gone, anyone know what the latest version of their software was?
I know, it was me asking for support of some older Lattic CPLDs which
pushed them over the edge... ;-)

Hi Errol
just found your post regarding surplus Interak kit. I
suppose it has gone long time ago.
If not email me bacjk and we can talk.

I'm currently looking at the HP50962 SRM Coax interface PCB. This is a
(custom) netowork card for HP9000/200 copmputers.
I can't indentify one the the ICs, which basically links to the Coax
netowrk cable. It's made by AMD (big AMD logo on it), and carries the HP
house number 1826-1388, which I can't find anywhere.
It's a 24 pin ceramic DIL package, and I've identified some of the pins
:
1 - to ground trhough a resistor (maybe soemthing like Rx gain set)
3 - ground
4,5 - to a pulse transformer, the other side of which goes to the coax
connector. Rx inout?
6,7 - ground
8 - Clock input
11 - Rx Clock output
13 - Rx Data output
15 - Tx Clock (output??)
17 - Tx Enable/
18 - Tx Data
19,20,21 - +5V
22,23 - To 4,5 via low-value resistors (and thus to the pulse
transformer). Tx Out?
Looking down lists of ICs, I wonder if it's related to the AM7960 or
AM7961, but I can't find data on those anywhere.
So :
1) Does anyone have the data sheets on those ICs on-line anywhere? (As
ever, please don't send pdfs or other large files to me here, but if you
have said data sheet as a pdf, I can tell you how to get it to me).
2) Any other ideas as to what that chip might be.
Thanks in advance
-tony
