I was wondering if anyone here has experience with the FD55-B with head
load solenoid.
I have a few working ones, but this one is not, and when I look at it,
it differs from the others in that the head "wiggles" up and done on the
side nearest the solenoid.
I can see it is tight on the rail oppose the solenoid, but on the side
nearest, the back of the head does not connect with the rail on the back
(which seems correct, as there is a piece of that extends out and looks
to slot into a sensor.
But, I'd assume the front mount would hug the rail, but it only does on
the top.
By pushing the head close to the disk in use, I can get it to work, so I
think this loose head issue is the only one.
I guess:
* Anyone seen something like this?
* Is this a broken rail mount on the head, or something else?
* If its broken and probably can't be fixed, anyone have a parts FD55-B?
* Can one replace the head on these (it looks like you can, but I admit
I have never changed parts in a drive mech.

I have some 3.5" PATA drives. One WD2500 250 GB drive and two Maxtor
Max Line II 320 GB drives. All three passed SMART long tests.
If you need any, they're yours for the price of a PDF shipping label.
Hi, located in Eastern MA, I already have a couple of interests, but
I'll see what comes in. Multiple q-bus boards that can easily ship, a
VT103, a BA chassis 9x4 I think and two RX02 units.
Hi Everyone,
I'm new to this list so please let me know if I am doing something
incorrect. Anyway, I have a bunch of Qbus stuff (RXV21s, RX02s, memory
boards, 11/23s, etc) and I am getting to the point in my life that it
all needs to go to a new home. I would like to know if anybody has
thoughts on where I should post the list or sell it. I could always do
Epay, but I'm not sure that is the best place. I thought here or
Vintage would be better but I'd like to hear thoughts from somebody that
has already been there.
thanks in advance
Joe Heck

A very left field question, but many moons ago I wrote some software using Nescape IFC. For those with long memories that was an early GUI library for Java that predates Swing.
For no reason at all I'd like to get this software running again, but noticed that I probably need a 3rd party library that was produced by Indius. These IFC add ons provided a fantastic grid and tree component.
The software was I believe finally released with a GNU license in the 00s but despite searching on archive etc I've not been able to find it.
Does anyone by any chance have an archived copy ?
Netscape IFC was quite a big thing when it was released by the way, and many books were written about it. It was also bundled with Netscapes browsers in the day, so available wherever they were installed.
I believe the team that created IFC went on to make Swing, which is in many ways similar, but added a lot of bulk which at least in the early 00s made things slow.
Thanks
Ian
Hi all,
I'm dreaming to build sometimes my own Bit Slice CPU (when I have spare time)
and I have collected several IC's in the last years for this purpose.
Today a small antistatic bag with 4x IDT49C402BG84 and two IDT 49C410J
fell in my hands while I was sorting some stuff.
I know what they are and what they could do, they are able to help me
to build a Bit Slice CPU w/o very large PCB's connecting hordes of 2901 etc.
Besides of that they are CMOS and should draw much less power.
But I have a problem with the 49C402: All datasheets that I could find
until now, don't have the pinput auf that nice PGA84 package, there are
DIP68, LCC/PLCC68 G68 or PG68 and QE68 "Cerquad" pinouts listet in every
datasheet, but I have 4 chips in a PGA84 housing...
This ebay page has pictures: https://www.ebay.com/p/10020043211
I don't have anything todo with the seller.
Can anyone help finding the pinout?
The chips itself don't seem to that seldom...
Kind Regards,
Holm
