DOS laptops up for grabs

Sun Sep 25 18:41:09 CDT 2016

I've got quite a stack (more than a dozen) first-generation DOS laptops that 
are headed for the recycler unless someone wants them.  They re mostly 
Toshiba T-1000 or T1000SE units, but there's a Tandy in there also, and 
probably a another outlier or two.  There are also a few Portege's running 
Win-95, and a few fabric laptop cases.  At one time all of these worked 
(obviously), but I'm sure that most don't now, for various reasons.  A few 
may have been cannibalized a bit, but for the most part all the parts are 
there.

I'm not looking for any cash for these, but I don't want to pay anything 
(like shipping) either, especially since the electronics recycler is less 
than three miles from my house.  If anyone wants to pick these up (I'm in 
San Carlos, near Redwood City, CA), or wants to pay me to ship them (at cost 
only), let me know.  At the end of this week (01-Oct-2016), they'll be 
gone...

I know it's a long shot, but does anyone have a manual for a SpectraGen
4B Video Title Generator?  I am trying to resurrect one, and it seems to
be a Z80-based unit.

I had it on fiche, which I scanned this afternoon.
It should be up on the bitsavers mirrors by morning PDT under pdp11/xxdp
along with rev E of the XXDP+ users guide.

I'll probably also do the RX02 diags if I can find them for Don, though
he may have them on fiche.

The step and repeat fiche scanner isn't on line yet so I used the Canon
manual positioning one. It's tedious, and it gets out of focus easily, but
they are better than nothing.

I was able to get ZRXDC0, ZRZEA0, and ZRXFB0 listings from the fiche images 
on
http://www.retrocmp.com/tools/pdp-11-diagnostic-database
so I am fine for RX02 diagnostics listings.

I will be visiting Albuquerque, Phoenix, Tucson, and various points nearby 
and in-between shortly.Any recommendations on electronics surplus and junk 
shops to check out? ?Some of the most famous, like the Black Hole in Los 
Alamos are long gone. ?Any other must-see attractions for the classic 
computer geek?

Denise sent me the image as well.

dfitoimd has now been renamed to fluxtoimd, as it now supports both
DiscFerret and KryoFlux image input. I've partially added HP M2FM
format; it now correctly decodes the address fields, but I have a bit
more work to do on the data fields. I expect to have it completed
tomorrow.

> - 0xD0: ECC data address mark

Any idea how they use that? Aside from that being included in the list
of address marks in the service manuals, it's not described at all.
Since the 7902/9885/9895 don't do ECC, perhaps it was reserved for
future use.

Wouldn?t you know it, the same day I decide to order a ribbon and some paper 
for my HP 82905B (aka Epson MX80) printer, the AC line filter cap (C1 on the 
MFIL board), expelled its magic smoke rather impressively.  After some 
cleanup, the printer has been banished to the garage until the smell 
diminishes.  It appears to be a 250 V, 0.1 ?F X type.  What manufacturers 
have good reliability for this application, in your opinion?

That?s a common item on Tandy power supplies so I?ve replaced a lot of 
these.  I?ve used this replacement numerous times with great success.

The VMS documentation mentions specification for the Digital Storage
Architecture that cover media formats. I have looked at the DSA folder on
bitsavers and cannot see any document that covers media formats. Is this
documentation available anywhere?

Thanks
