Picked up some Apple IIgs boards yesterday and I need some help with them. First is a Q-RAM GS memory board. This looks like it has 4 meg on it and the only thing here I'd like to know is what the 2 switches are for and what sizes of simms will it support. Any doc would be helpful. There others I'm not sure what they are. The first is labeled as "Quickie Controller" "Vitesse Inc." "P/N 121489" There is a cable that goes to one of those round plugs like the the serial and printer plugs on the IIgs. What's the official name of those connectors? The other is from Apple but I don't know what it is. It has a cable off the back to a 25 pin connector. On the board is "Apple Computer 820-0153-A" Over one set of chips it says something about "sandwich II". I don't know any of the chips on it (never was great at IDing more than a handful of chips). Could post pics if it would help. Anyone know anything on any of these boards? Thanks. ----- "What is, is what?"

>I've heard of those too, and was thinking about getting one for some of the >older macs I had, before I decided to get rid of 'em. IIRC they weren't the >most elegant of things, and drivers were a problem. I've used the Asante ones without a hitch for years. No driver problems at all. You just need the Asante driver (last I knew, it was still available on their web site, just burried). The driver hasn't given me any problems up thru OS 7.6.1. I don't know about OS 8+, but any Macs that can use OS 8 have an alternate means in which ethernet can be added. I have used the "Mini" which is the one that needs SCSI Bus power (and so can't work with a Mac Plus), and I have used the "Micro" which is the one that has the HDI-30 connector and is designed for powerbooks. The only problem I have ever had with these is when I dropped one off a desk, it stopped working. Other than that, there was a minor config problem in using one with IPNetRouter, but that was a known issue with IPNR, and IIRC, was actually a problem with IPNR and not with the Asante Driver (they work fine with IPNR, it just needs to be on the local network side, and not the internet side of a dual ethernet firewall/nat setup). I am hoping to lay my hands on a "desktop" version shortly, so I can use one with my Mac Plus (the "desktop" version has an external powersupply and doesn't need the scsi bus power to run the device). -chris <http://www.mythtech.net>

>Would they call common network connectors "8 pin RJ-11"? >Or would they call them "8 pin telephone connectors"? Neither, 8 pin RJ's are an RJ-45 (11 is a 4 pin, comes in either standard or handset sizes... can also have just 2 pins for "cheap" cords... 12 is a 6 pin, same physical size as a standard RJ-11) Ok, now you can hit me for being a wise ass ("not in the face, not in the face" -Arthur "The Tick") -chris <http://www.mythtech.net>

It's a small 5-port repeater, with one of the ports being AUI. It's meant to extend an existing hub, but it can be used as stand-alone. It's line-powered, too, I think. So you might need to have something plugged into the AUI port (eg a computer with an AUI drop cable). -- Pete Peter Turnbull Network Manager University of York

I've no idea how on-topic it is, but... This last week I rescued a "Asante NetExtender Hub" from the trash. In looking at it, it would appear to be a combination Ethernet Transciever/4-Port 10BaseT Hub (yet it's smaller than most 10BaseT Trascievers). Is it what I think, or is it something different.

Tonight's S-100 find detailed inventory

by erd_6502＠yahoo.com

OK... first of all, let me say that an XOR box weighs a ton. Second, here's what I have - more cards than a single computer needs. I wish I hadn't given away _all_ of my 68K S-100 stuff to a friend years ago (but at least it's in good hands) In the backplane when I got it: o COMPU/TIME UFDC-1 floppy disk controller, c. 1983 Labelled jumpers for drives A-D, each with "5/8", "S0" and "S1" 1 34-pin connector 1 50-pin connector WDC FD1795PL-02 FDC chip no docs o COEX 64K static RAM board, c. 1984 32 Hitachi M58725P 2Kx8 SRAM chips no docs (but jumpers are labelled) o COMPU/TIME SBC-880 CPU board (c) 1980 no CPU chip Loose boards... o QT Computer Systems RAM+65 SRAM board, c. 1981 32 2114 SRAMs (16K total) missing IC49 (near the S-100 fingers, probably a 74LS240 or 74LS244) labelled DIP switches no docs o Vector Graphic 8K SRAM board, c. 1980 64 2102 SRAMs no docs o Seals Electronics SRAM board, (c) 1976 64 2102 SRAMs (8K) no docs o SSM VB1C video card, c. 1980 docs o SSM VB2 video card, c. 1979 chips still under plastic docs o Cromemco TU-ART Digital Interface, c. 1982 2 parallel 2 serial NIB docs o Vector Graphic Bit Streamer serial card 8251 SIO chip no docs o MITS 88 UIO "Universal I/O Card"(?) c. 1977 M6850 AY-5-10134 26-pin Berg-styled connector 10-pin .154"(?)-spacing single-row connector (P-2) no docs o Unknown-brand mystery card (video?), c. 1979 8212 2 x 2708 EPROM (each marked 'FW II Gen', one with down arrow, one up) 4 x 2114-3 SRAMs 6-pin .1"-spacing single-row connector U42 missing (24-pin .6" DIP) no docs o SSM CB1A CPU board, c. 1980 INS8080A 2 x 8212 2 x 2708 (marked "0-3V" and "4.7V") 2 x 2114 docs o SSM 8080 Monitor V1 docs command summary listings So, all in all, a good night's work. I'd love to learn more about what I have, especially the stuff with no docs. Some of the docs I do have, have schematics, but some of it is assembly and rudimentary test/programming instructions. I would appreciate any and all tips to online versions of docs for this stuff. I would also appreciate any tips for getting an OS for the box with its COMPU/TIME cards. I suppose one way would be to receive a 5.25" image, reconstitute it and boot the system off of mini-floppy, then format a disk or two on the 8" floppies and go >from there. -ethan __________________________________________________ Do You Yahoo!?

Digital Rainbow 100+ PC

by ajwotherspoon＠shaw.ca

For Sale or ???: DIGITAL RAINBOW 100+ COMPUTER This early 1980's machine is designed to boot DOS, CP/M and as a DEC Terminal. CPU - Model PC100-B2, Serial #WFC3514 - with dual 5.25" floppy drive and full height hard drive Colour Monitor - Model VR241-A, Serial #Y31-008107 - with video cable Keyboard - Model LK201AA, Serial #B033602238 - with cable [plugs into video cable] Printer - Model LA50-RA, Serial #TC73817A - with printer cable Circuit boards in CPU are as follows: 5416206 5416205-01C1 [PC100-B MOTHER BD] 5415961 5015960-01C1 [PC100B MEMORY EXTENSION] [27 sockets for DRAM; 9 populated with 50256-150 chips] 5415688 5015687-01J1 [No description on board] 5415482 5015481-C1P1 [PC100 RX50 CONTROLLER] [Floppy Drive] 5416019 5016018-A1 [PC100 RD51 CNTLR] [Hard Drive] The hard drive is a Seagate ST-412. No documentation. No diskettes. Includes 3 power cords. In working order (except do not know how to test printer which seems to POST OK). CPU will boot from hard drive into CP/M but not DOS. Plastic cases are quite suntanned (i.e. yellowed) except printer. Pictures of the machine may be viewed at http://members.shaw.ca/ajwotherspoon/rainbow/. Located in Victoria, BC, Canada. Shipping (including cartons), insurance and customs broker (if required) are your choice and cost. Using a bathroom scale the approximate weights are: CPU - 32 lbs. Monitor - 36 lbs. Keyboard - 4 lbs. Printer - 20 lbs. Cables - 4 lbs. Total - 96 lbs. (plus shipping cartons) I have a box that could be used for the printer if packed in Styrofoam peanuts. The hard drive should probably have its heads parked before shipping but I will need instructions/software. This is a collector's item, I am sure, but I have no idea as to its value and I am not a collector. It was purchased new here in Victoria from Computerland about 1983. I found it at a garage sale a few weeks ago. I would hate to see it scrapped but I can't store it much longer! I will not separate any components - it's all or nothing! For my efforts I would like a few dollars in addition to the shipping/insurance but not an outrageous sum. At www.omnicorp.net/dec.htm (in New Jersey) I see the CPU is listed at US$85, the monitor at US$95, the keyboard at US$50 and the printer at US$75 (all tested and guaranteed). I am not looking at anywhere near these prices. For further information or to make an offer please send email. This machine was posted on December 19, 2001 in the comp.sys.dec.micro Newsgroup and I have had one expression of interest so far. Alex

Seagate ST32550N vs Quantum XP32150 - which is better?

I can't tell you anything about the XP32150s, but I've set up probably three hundred ST32550Ns and have had very good luck with them. Their write caches ship set to "disabled" by default, though, so it's usually a good idea to stick it on something that'll allow you to edit the contents of Mode Page 6 to turn it on, if my memory is correct. -Dave -- Dave McGuire St. Petersburg, FL "Less talk.

VAX 4000-200's on eBay.de

by wilby98＠yahoo.com

On my quest to get more "stuff" of a classic nature I came across these items on eBay in Germany. http://cgi.ebay.de/aw-cgi/eBayISAPI.dll?ViewItem&item=1311492128 Now, I do not speak German and in fact know very little about VAX's in general. But for some reason the notion of having one is appealing. Also, these items are "relatively" close (me being in Holland). Time is running out on these but it looks like they have a minimum acceptable bid. Does that mean that if the bid is not met you can negotiate a price outside of the auction? (I don't know much about eBay either). How do they look to you VAX owners/operators? Bill Amsterdam, NL

VESA Bus Multi-IO cards

by mythtech＠Mac.com

If anyone is interested, I saw in at the local thrift store 4, what appear to be brand new, Data Technology DTC2278V2 VESA Local Bus Multi IO Cards. They have two serial, 1 parallel, FDC and IDE. I think the price was $10.00 per card (I didn't write down the price in my infinite wisdom, and I saw them about 6 hours ago, so like most of the rest of my day, the info is slipping out of my head... but I think it was $9.99). I don't care about making money off them, so the cards will be actual price (price + 6% NJ tax), plus shipping. Figure they will be about 1 lb when packed, shipping from 07450. If anyone wants me to pick one up, let me know (I remember there was a VESA discussion going on here not too long ago, so I figured some of you might have an interest in one) -chris <http://www.mythtech.net>
