Things related to the Z80, 8080 processors
Baby Blue Z80 card for IBM PC
I have two sets of Baby Blue Z80 card docs and disks.
First set from Microlog: The Baby Blue files I have total about 100K. They appear to be from 1983 and include references to Version 2 and version 1. The lable on my copied disk says "Ver 2.04K". I'd charge $2 plus shipping for this disks if you buy this with the manuals. The document is a copy of the Microlog Baby Blue CPU Plus User's Manual, from 1983. Copied as two half-sized pages per sheet, there are 48 sheets. There is also a manual for BSTAM which is some kind of communications program, of 9 sheets. We'd charge $12 to copy this pair of manuals.
second set from Xedex: I also have an original Baby Blue document, as above but from Xedex Corp and labled Version 1.2. It's a different manual with illustrations of a board with a Z80 near the top edge, a DIP switch near but not above the edge connector, and with 8 RAM chips on the vertical edge farthest from the ISA connector (arranged as 5 + 3 chips). this manual is 56 half sized pages so we'd charge for it as 28 sheets copied two pages per sheet. So this would cost $6 for a copy. It refers to similar programs as the Microlog manual. There are two 5.25 inch disks with this "original" manual. I'd charge $2 for a copy of these onto a 3.5" diskette, presuming I can read those disks.
I have a few Baby Blue Xedex cards, untested, sold AS IS. Cards as pictured, or one with a pale blue circuit board but identical layout and chipset. DRAM chips removed on all of them. All TTL type logic chips (type is labled on each board) except one delay line chip. Some have some socketed chips. Cosmetically, they look OK. Ask me about a price on these.
2.4GHz or 2400MHz reciever and transmitter line amplifier Sorry, sold out!
Later on, we picked up some AC "wall warts", which instead of a DC type power connector, have a "type F" RF male connector. Type F is what the cable TV companies use. These are rated 12VDC at 500mA. Are these the "injector" type power supplies? I don't know. I can at least confirm they provide DC power. But you can have these at $5 each plus shipping and handling. I have maybe 20 or more.
DEI TR-711 50-200MHZ AM/FM defense receiver
(Defense Electronics Inc) DEI model TR-711 receiver. Weighs about 50 lbs, roughly rack-mountable size. It has some nice features like bandwidth controls (kilohertz to a MHz as I recall) and 2 switchable plug in IF filters, AM and FM demodulators, triple conversion, My unit has a front end for 50-200MHz. Everything is a plug-in: bandwidth filters, IF filters, demodulators. These units were made around 1970. Seems to be functional with a simple wire antenna, but I need to connect a serious antenna to see what it can really do. Runs on 110V AC 60Hz of course. All transistor, not tubes.
A DEI catalog is
at this link. Here's a GENERAL description of what DEI offered with the TR-711: I have two boxes of 8mm tape data cartridges, new, sealed, as follows: Dual 8mm tape drive, SCSI, in external box two Exabyte 8500 drives
in external case with SCSI-2 connectors. Initial tests are that one drive
accepts 8MM tapes, the other will reject the same tapes. Cannot test further
until SCSI address set to allow use of "good" drive. Looking for offers
before I test further.
4mm DAT tape drive, SCSI, in external box. Drive identifies
as "Archive Python 01931-xxx 5.56", and has a lable "Conner CTD8000E-S".
Has SCSI-1 connectors. Specs say 400Kbytes per second transfer, and 4GB
uncompressed storage on DDS-2 120m tape. Drive tested using Win 95 Backup,
saved and verified 1.5GB on tape. Make me an offer on this tested drive,
with a few tapes included.
Archive EAX6GP-60EP/150EP tape drive. Uses cartridge tapes.
Not tested.
IBM 7208-001 8mm tape drive, EXABYTE 8200. external SCSI tape drive
with AC supply. Original connectors on back replaced with SCSI-2 type
HD50 connectors and cable and terminator. Not working. Castlewood ORB 2.2Gb, orb2se00, scsi tape drives external, 2 units
Syquest EZdrive 135, 135Mb cartridge not included. SCSI external drive, untested.
DC2000 data carts, 40 MB, from 3M: 9 cartridges still sealed, in two boxes.
DC6150 cartridge tapes, unused, sealed. 13 tapes.
6" by 4" data cartridges, 1020 foot length, 250MB. 10 cartridges total
9 still sealed, in two boxes. No brand name, dated probably 1992.
We acquired these in March 2003. They were apparently purchased in 1975, according
to the original boxes they were shipped in from the manufacturer. Almost all are in
original packing in original boxes and those in original shipping box from manufacturer.
These product are currently available from Ferraz Shawmut, A Web search on that name
and the product name (A70p100 or A50p100) will point to a PDF of their data sheets.
Contact me to make offer.

IBM Thinkpad 4MB PCMCIA cards PAR Technologies PCMCIA AndRAM
cards for IBM 340 360 370 Thinkpad. Model numbers C34THKX04 or C70THK04.
Appear to have unique connector, not standard PC card. Ten available (Jan 2002)
a few in packages with brief instructions. Condition not known, sold
AS-IS. Give me a decent offer for all of these, I'd hate to sell them
one at a time! Obtained May 2006. Several spools of bulk multiconductor wire, clean and in good condition, on
original wooden spools. Selling only as spools, not by the foot! NOte weights and lengths.
"Small spool" and "larger spool" are relative sizes for comparison. Looking for offers. Lengths may be short
a few feet from sampling, but no guarantees as to actual lengths. Pictures can be taken to respond to
serious offers. Easy enough to tag a spool and ship it! (some has been sold, we can confirm what is left.) In early
2009 local spot price for scrap bulk wire is 15 cents a pound, $15 per hundred pounds.

>1400 feet of two-pair, high temperature, overbraided "thermocouple (extension?) wire", in original steel barrel. Consists of an outer overbraid 0.4" diameter .03" thick, copper or bronze coated steel. Inside is fiberglass-like braided layer and silica-like filling and a pair of inner braided .25" diameter .02" thick as above. Inside each of those are a pair of .032" (#20) diameter bare wires, grey metal, one shiny one dull, composition not obvious. NO COLOR CODING. Label says "8/27/86 1400' of P.S.C. type 39,
602-4-20SL-5-1 two twisted pair HV Thermocouple cable" and "PSC division, M W Riedel and Co, 300 CYPRESS AVE, Alhambra CA (213) 283-7694". PSC could be Pyro Service Company. In 2008, 300 Cypress Ave. is a location for several distributors of electronics. For information on thermocouple wire,
look at this Omega Web site.
Information from the lab where this wire was obtained, includes the following: "Thermocouple wire XC-E-20 (chromel-constantan covered with Nextel-312 fiberous insulation and braided Inconel jacket" for surface pumping panels, covers...internal vacuum vessel wall." I do not know if this description matches the wire I have. But Chromel is described as "shiny metal" and Constantan as "Dull metal" in type-E thermocouples. Both are non-magnetic. Some manufacturers of thermocouple wire use "20SL" to refer to 20-gauge "special limits of error" wire, a higher grade of wire.
These items were used in Appletalk networks, not very common today. But I have several strips of Mod-Tap RJ45 to telephone 50-pair connector strips.Each 50-pair connector goes to 12 RJ-45 connectors. Most of those connectors have 4 of 8 pins connected; some have all 8. here's one photo and here's another photo. A pair of these
50-pin units can be mounted on a narrow aluminum strip, and mounted on a 19-inch rack. I have a few dozen of these units. Mod-tap numbers include "27-34Y-26" and "27-348-26" and "27-64E-246".

Amp-trap semiconductor fuses, 100 amps
High power fuses
About 12 high-power fuses by GE. THOUSANDS OF AMPS, THOUSANDS OF VOLTS.
Constructed of silver ribbon (one troy ounce each) in a sand matrix. Weigh about
10 pounds each or so. Old but apparently unused, one is dated 1983. Typical model
number and spec: 218A4293P12RB, 4.8KV, 80KA Conversation piece,
I suppose, but they also have an ounce of pure silver in them, so that makes them
worth a few tens of dollars each. The sand is very high grade also.
