Jeff,
I tried a ST-251-1 but it wouldn't work. Here's the story:
I picked up a HP 9133XV drive with a bad drive in it. The XV is the one
that you can partion into 4 so that it looks like 4 HP 9895 floppy drives
to the system. It's the only hard drive that can be used on the HP 85, 150
and some of the others. This one has a Seagate ST-419 drive in. I replaced
it with a Seagate ST-251 that has the same number of heads but more tracks
and is smaller and faster. The system recognizes if but it won't format it.
It says that the drives are bad. I'd like to get it running again since the
XV drives are hard to find.
The 251 does have fewer sectors (17 vs 32). I don't know if that's why
it failed or not.

Latest buy from the Resource Shop attached to Glenorchy tip was a box
containing 6 Atari 2600 consoles, plus 40 odd C64 floppies & about 20
cartridges for the Ataris. I'm keeping the C= disks, but if anyone in Oz
is willing to pay postage, they can have the Ataris & carts (I don't
collect 'em - but for $10 I couldn't say no :-) ) Oh yeah, there's a
Dick Smith VZ200 put aside for me as well, again, I don't really want
it, but will forward it to someone who does (they want $8 for it,
includes tape deck & two joysticks).
cheers,
Lance

I wish I had a MINC... I have a couple of Mini-MINCs (as the PDT-11/150
with the EIS/FIS was referred to, apparently). It is a pdp-11, so it
runs RT-11.

I'm afraid that I haven't found any documentation that could help me
understand how to use OS278 or PAL. A few specific questions, if there's
no online users' guide of any sort:
How do I access the second floppy drive?
How do I make an empty file?
Please give me an example of what command you would enter to make a PAL
'Hello, World!' program, save it, and run it. Thanks

I opened up the 419 drive, No wonder it failed, someone drilled a 5/16"
hole thru the cover and all three platters! This thing was mounted under a
circuit board and inside a steel case. Everything was very neatly put back
together. Who would go to that much trouble to wreck a drive and why?

I have a noisy ST 251 hard drive. It sounds like the bearings.
Is it heretical to think I may be able to lubricate the bearings?
They appear to be easily accessible on the bottom of the drive.
Thanks,
Dave
The Dayton Hamfest is a fabulous show. It is THE LARGEST amateur radio convention [it's "official" purpose]. The Hara arena is a very good size facility, I'd guess in the over 100,000 sq. ft. range (perhaps WAY over), and it's all indoor, heated/air conditioned [not that it works with 35,000 people in the facility], and all commercial vendors, many, many of which are used computer and surplus dealers (there is lots of new stuff also). It's about 60%-70% computer, the rest general electronics and communications [radio] equipment.
The flea market takes up the entire parking lot, in excess of 2,500 vendors. There are many commercial exhibits in the parking lot also, you will find a number of very large tents (10,000 square feet range each). Mendelson surplus always has a large tent, and almost every year Radio Shack [as in Tandy] collects their entire surplus and returned merchandise stuff from all over the nation and sends it all to a big tent at the Dayton Hamfest where it is sold for often ten cents on the retail dollar. However they didn't do this last year, for the first time I can remember, but they still had a huge indoor exhibit with many items, new, at 25% to 50% below normal store and catalog prices.
The show is logistically difficult to attend for several reasons. First, it brings in so many people [over 25,000 plus a large local population] that poor Dayton, which is hardly a tourist mecca, is complete swamped. You can forget about finding a hotel at this point, the people who do this show get their reservations a year in advance. You may have to stay in Columbus or Cincinnati [both about 70 miles away], fortunately both are directly on an interstate highway and it's not a bad drive. The other problem is parking, since the entire lot is flea market there isn't any ! There are some LARGE fields around the complex that are used for parking, expect to pay $5 to $10 per day, and they are not paved, or very close, which become a real issue in bad weather. Then there are remote lots with busses, but that's a hassle also.
The show is May 14, 15, 16.
Here is an alternative, the Dayton Microcomputer association has a twice a year computer show at the same site. It's just about as large as the Hamfest, and it's ALL computer. There is no flea market, the parking lot is used for - surprise ! - PARKING ! It's almost like having 3 Dayton Hamfests a year, except that two of them don't have the flea market. This year's dates (it's only a two-day show):
Spring: March 13-14
Summer/Fall: August 28-29
I plan to attend all 3 events.
I don't read German But the pictures are perfectly understandable...
