OK, spring cleaning time again. Free for pickup in the Washington DC
suburbs: strictly first-come, first-serve, and I strongly want to get rid
of the stuff this weekend. Some items are large and
will require a truck (or a truly full-size station wagon.) If interested,
drop an E-mail to me at "shoppa(a)trailing-edge.com" or call on my cellphone
at 202-320-9410.
OK, the list - largely an inventory of stuff that hasn't been used in
at least two years:
40 RL01 and RL02 packs, with various diagnostics and other tools on them.
A Wright-line cabinet with the metal racks for holding the above packs.
6 RL01 and RL02 drives. Rack-mounting rails for the same.
RX02 drive unit.
Gobs of RL01 and RL02 cables. Also, all my miscellaneous RL termiantors,
buttons, unit select plugs, and lamps.
2 Storagetek 1600/6250 BPI 9-track drives, Pertec formatted interface, rack-
mounting hinges.
Many BA11- and BA23-style Q-bus enclosures. Bunch of 11/23-era CPU's
and memory for whoever takes the enclosures.
One pedestal-style BA23 with most (all?) of a Microvax III in it.
One BA123 with most (all?) of a Microvax II in it.
PDP-11/04 in 5.25" high box, H777 power supply.
Several H960 (6-foot) racks will be available, assuming that you
(or someone else) will help me carry them up the stairs.
A bunch of Trimm drive enclosures for 5.25" drives. Styled like BA23's.
Many 5.25" FH SCSI and ESDI drives. Many 5.25" floppy drives.
Many Shugart 8" floppy drives.
Tim.

New subject: ISA/486 Board Question
Most ISA com/lpt/fdd/ide add on boards for 386/486 have a chip like
W83787F or so. LPT and Com ports have pin-assignable irqs, sometimes IDE
has a choice (14 and 15).
Is there an ISA card that has the IDE irq assignable to any IRQ?
U guessed right: I'd like to stick a secondary ide drive (CDROM
obviously) into a 486 that has only one ide (IRQ14)drive, but no plug
for a secondary drive, and no, I cannot use the ide cable as it is a
laptop, but yes, it has the bus connected to a dockstation. And yes I
can stick a scsi card plus drive into the docking station and it will
work in dos, win95 if I find the drivers...but I want to do that with
ide cd's.Is this a doomed idea because the bios wont let me do it?
...the old idea of having 4 ide devices on a single 486 cpu....but with
a twist: the primary ide on the first chip, the sec. on the other....how
do I tell the cpu to look for the sec. ide on the other chipset?

New subject: ISA/486 Board Question
Most of the time the IRQ selection is done something like that :
IRQ out from ASIC -----------+---o o------- IRQ_a to bus
|
+---o o------- IRQ_b to bus
|
+---o o------- IRQ_c to bus
|
+---o o------- IRQ_d to bus
In other words there's one IRQ output from the ASIC for each port, and a
jumper block to connect that signal to the right pin on the ISA
connector.
So if the jumper block is missing, or doesn't go to the IRQ line you
want, you can just cut the track (in this case between the ASIC and the
IRQ14 pin) and connect the signal to whichever bus line you want. You
need an ISA bus pinout, but that shouldn't be too hard to find.
-----------------------------------------------------------------------
Nothing to it: I can actually see the lines from the isa bus to the irq
bank of plugs.
------------------------------------------------------------------------
-----
Don't you also need to change the I/O address of the IDE port on the
add-on card? This can sometimes be kludged (if there's no better way) by
inverting one of the address lines going into the ASIC (but watch out it
doesn't move the COM port, say, to clash with something else), or by
using
some logic to fiddle the addresses when it detects the right addresses
for the IDE port.
-----------------------
now that's more artistic!

New subject: a few Data I/O PROM programmer parts to give away
Hello all,
Today I happened to run across a Data I/O 288 programmer, and it has a few
bits that I don't need. So they're free to whoever does have a need for
them (though reimbursement of mailing would be nice). I have
- (4) 701-2311 PLCC32 ZIF to DIP32 adaptors (1Mb layout?)
- (6) 701-2162 PLCC32 ZIF to DIP32 adaptors (512Kb layout?)
- (1) extra of the gang units (PR32?) with 8 DIP sockets on it, not ZIF but
the TexTool ones the ZIF sockets plug into. The connector to the main unit
is a little beat up, but it seems to work.
Drop me a line if you're interested,
Jim Kearney

TTi seems to have gone away.... I've looked, and can't find anything.
I picked up a couple of 8mm Tape drives the other day (TTi 8210 and TTi
8510) with the cool displays, but of course... no manual !
Must be someone out there that has a manual? or can give a pointer to an

need a hand with.
Thanks!

If you hook them to a reasonably intelligent SCSI interface, e.g. ADAPTEC 2940
or the like, which will allow you to do simple things from the BIOS promt, you
can see what you're dealing with and what effect the switches have.
It's true, Maynard and others repackaged these drives, but if you allowed them
to identify themselves, they appeared as Exabyte drives with correct
nomenclature. The only problem you could run into is that the drives might be
differential. If that's the case, you need a differential controller.

I must take exception. IMNSHO, the Adaptec 2940 _isn't_ a reasonably
intelligent interface. Buslogic, NCR, Symbios, and LSI all had better
contemporary chips, mostly with better detection and more features.
And, it's Adaptec, not ADAPTEC.

I won't argue that. I just wanted to point out at least one reasonably
capable adapter that has a BIOS that enables you, the user, to look at how the
devices attached to the SCSI identify themselves.
BTW, it's spelled ADAPTEC on the box in front onf me ...

I've had some trouble tracking down viable mfg's of SCSI hardware, since I've
developed a somewhat jaundiced view of ADAPTEC. For which busses is LSI
selling SCSI controllers? Since ADAPTEC bought SYMBIOS, and IBM acquired by
buying the company that bought them, I figured it was getting to be rather
slim pickings out there.
Qlogic makes some pretty popular LSI's for SCSI and other interfaces, but I
see few of them on the products in the shops.
