BIG RGB monitors and cables

HP SureStore CD-ROM tower on Ethernet! This HP product J3277A has seven CD-ROM drives in a network server for Ethernet networks. Tested and worked with Win98 SE system. Downloaded drivers from HP. Ask if interested.

other workstations and related items

Some of these have been moved to our DEC and other equipment page.

Texas Micro or Radisys single card Pentium board. Texas Micro P54C 946 F23463C, may also be Radisys EPC-2102 SBC. Single card PCI/ISA board with ultraSCSI controller, four 72-pin SIMMS, Socket 7 Pentium 133MHz processor, ISA and floppy, serial and parallel ports. Also have passive motherboard with ISA and PCI slots. Disassembled after running OK. Modest price for these two cards, ask. Radisys Web site has online manual for their model.

Things related to the Z80, 8080 processors

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.

RF amplifiers, radios

Cisco AIR-MP20B 802.11b radio modules. I have about 25 or more of these. They fit into Aironet AP1100 or AP1200 series wireless access points. They are apparently left overs from upgrades to the MP21G, the 802.11G modules which is what is described on the box and docs. The docs say something about a "mini PCI connector". These are small circuit cards with a small edge connector. In original boxes, in antistatic bags, with installation instructions. Do not include the antenna which is part of the WAP products.

Panasonic RF-4900 3-30MHz receiver

Panasonic RF-4900 3-30MHz receiver, plus AM & FM. Photo is of another unit, mine is in good cosmetic condition. Seems to get all 3-30MHz bands OK, plus FM (mono) and AM bands. Has numerous controls for volume, BFO tuning, treble and ass, RF gain, narrow/wide band switch, BFO off/on, and the meter switches between battery and RF. Can turn off digital display of frequency to save battery power I presume. I tested with a three foot solid copper wire for an antenna, in a basement. I got WWV at 5, 10, 15MHz (barely but consider the conditions). AM and FM stations were good, some shortwave stations. I see this radio for sale on the Web at up to $200. But this one needs a little work on the knob (details below), and I got it cheap, so I'll sell it for $129 plus shipping. Shipping weight 25 pounds packed.

Large reciever, weight about 20 lbs, about 19-inches width, built in the late 1970's, all discrete transistors. Also known as the DR49. Both versions have a fluorscent digital display for frequency. The RF4800 model has a numeric LED display and is less desirable. Takes 12V input and holds 8 D-cells. Manual not included.

Outside clean, inside fairly clean, slight dust. Only obvious problems are that one grain of wheat bulb is out on one of two band displays, and the band tuning knob is broken in the rear which makes it a little loose and fussy to turn. The knob is geared for pull to tune fast, push to tune slow, that's difficult with the rear broken. But the gearing looks OK but the back mounting plastics seem to be broken, you can see that visually when the covers are removed, but likely repairable. I THINK that the tuning control can be fixed by a simple plastic washer perhaps 1/8 inch thick.

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:

> TR-711 plug-in plug-in telemetry receiver, solid-state
> 105-2300MHz 10kHz-3.3MHz state and nuvistor, slots
> for one tuning plug-in, two IF filters, one demodulator,
> and one SDU, triple conversion, 30MHz, 4.3MHz,
> 455kHz IFs, rack mount 7" high

> Tuners: IF filters
> T-711(?) 105-140MHz 10kHz

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.

Fuses

Amp-trap semiconductor fuses, 100 amps

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.

Fiberglass package is about 1.5" diameter, 4 3/8 inches end to end. Studs (ferrule) at either end 1" wide, 3/4" long, with 5/16" dia hole. Center to center on holes is 3 5/8". No guarantees on these measurements but they are pretty close.

quantity about 140: Shawmut Amp-trap A50P100 type 4 semiconductor fuses. Packed in boxes of ten. fast acting fuse, 100 amp, up to 500 volts. Fiberglass package is about 1.0" diameter, 3 5/8 inches end to end. Studs (ferrule) at either end 3/4" wide, 3/4" long, with 5/16" dia hole. Center to center on holes is 2 7/8".
