I've got a TZ30 working on a pdp-11/93 at home, and working just
fine... In fact, I used it to load 2.11BSD, and RT-11 V5.7...
The TZ30 SCSI implementation seems to be more stable than the
TK50Z one...
It may depend on the board you use... I used the RQZX1, which was
qualified with the TZ30...

I've got a set of these I got some 15 or more years ago... I sure
do remember them. I used them to help my son learn a little about
computers and programming in BASIC (if you're lucky, flames regarding this
will be ignored)

While it's true that ensuring that no money changes hands except between
buyer and seller will remove the incentive on the part of the site owner to
support needless price escalation, that mechanism won't be effective to
encourage sane pricing unless there's a powerful mechanism, probably one
stronger or at least swifter than the legal system, to ensure that the
bidder and seller are held to their obligations.
My problem with eBay is not that the prices are unreasonable, though I've
felt they are. My problem is with the 70% advertised successful completion
rate of transactions resulting from completed auctions. This means that
only seven of ten auctions in which a bidder offers an amount equal to or in
excess of the buyer's demand, result in a transfer of funds for the
merchandise at auction. This doesn't include those auctions which result in
the buyer receiving a brick, and may (?) not include cases wherein the
seller receives a bogus check. It only considers those cases in which one
of the parties backs out.
Unfortunately, I don't see a reasonable method which can be used to fix this
problem. The free market says that an item is worth what someone will pay
for it. How can one depend on the likes of eBay to set the price when there
is no mechanism to bind the parties to their commitment to the agreed-upon
transaction? How can we improve on it? What could we do if we had a site
dedicated to the exchange of computer antiquities and oddities, to prevent
falsely imputed prices resulting from transactions, faked in order to make
record of prices at which commodities can not reasonably be traded?
Before we become too critical of eBay, we should, I think, have a positive
construct which addresses their shortcomings. EBay is, I believe, a good
idea, implemented as well as can be, though perhaps not, which, like our
form of government, is by no means perfect, yet is superior to whatever else
is available.

Lessee there are some points of order...
Alpha Micro AM100 was a sorta LSI-11 in that it used the same chip set and
was similar but not compatable in any way.
The Western Digital PASCAL Microengine was a P-machine and operationally
as well as programativcally very different from DEC PDP-11. It did however
use the same chipset.
The chipset is WD13 and it's functionality is determined by microms
(microprogramming roms). Alpha micro was very close to the PDP-11 but
far enough away to avoid copyright problems. The WD P-engine was oneof the
few direct P-code executing systems (a stack machine).
All very interesting machine as they were pushing the microcomputer envelope
for the time.

I missed the opening of a thrift sale that still had some possibly
interesting leftovers. Anyone have any info on the following:
1. Televideo TS0806/20: one floppy, one hd, z80 (I think)
2. Televideo T806H20 same case as above containing just a hd
3. DecServer 200/MC
4. Digital TK50Z-GA (can this be used on a Micro pdp?)
Would consider trades with anyone looking for any of this stuff
specifically.
TIA

Today I picked a copy of the Secret Guide to Computers (20th edition), I
remember reading these years ago when the guy offered free help over the
phone on any computer topic. Anyone else remember these books. John
Does anyone on this list collect Intel stuff? I've recently picked up two
Intel 5 slot rack mount multibus I chassis (this is the 2U size box), an an
iSBC 86/35 and an iSBC 86/05. The former counts as a singleboard computer
as it has ROM and RAM on board, the latter expects RAM to sit on the P2 bus
if I recall correctly.
I would prefer to trade for Q-bus stuff but reasonable offers are welcome
as well.
--Chuck
If you're interested in the GRiDPad 1910's I picked up, please let me know.
After I get this first batch out, whatever's left is going on ePay to try
and make back what I paid for 'em, perhaps even a little extra to cover the
hours I've spent testing them. Cost is $15 for working ones, $5 for
non-working (plus shipping). E-mail me off-list for more info.
(I'll only send progress updates to those who have said they want one (or
more) from now on. Thanks for being patient!)
