memory refresher on PUTR

Should the PC drive be a 360k floppy or a 1.2m floppy? Ideally, neither: 80-track double density. An RX50 is only single-sided (80 tracks, 10 sectors of 512 bytes per track), but obviously a double-sided drive will do, and that includes a "1.2M" drive if it's capable of doing DD as well as HD. > Wonder if there is some story as to the history of "disc" vs. "disk" :) HP > always used "disc". "disc" is from the Greek "discus", and is (or was, until recently) the more commonly accepted English spelling; "disk" is an Americanism which has spread to the UK. Acorn always used "disc" as well. -- Pete Peter Turnbull Network Manager University of York

DEC cards available

by kd7bcy＠teleport.com

I got these cards a while back(I think I asked what they were here on the list back in 2001), mostly MicroVAX II cards I think, all Q-bus. I'm mostly interested in getting these out of the way... I have no plans for building or keeping spares for a MicroVAX or anything beside my 11/84. Not sure what they're worth, and keep in mind they are untested. Make an offer plus actual shipping - I'll also consider trades for Unibus cards for my 11/84. Whatever the list doesn't want I'll probably put on eBay(I'll give you guys a week or two for those that don't keep up with their email very well). National Semiconductor NS638 - memory card with a 50-pin connector on the front Sigma Information Systems DZV11 clone unknown Emulex - marked TU0210401 M7551-CA MSV11-QC Q 4-Mbyte 22-bit parity/CSR MOS RAM M7164 KDA50-Q Q-bus SDI adapter 1 of 2 M7606-AF MicroVAX II CPU M7608-BC not in guide?

Mac SE/30 revived! woot!

by cb＠mythtech.net

>Now I go hunt for an SE PDS ethernet card. (Anyone have a spare?) I believe the SE and the SE/30 use a different PDS slot ethernet card. The SE/30 card is compatible with the IIsi, but I do not think it is compatible with the SE. However, that doesn't mean you can just buy an ethernet card for the IIsi and use it in the SE/30. The IIsi also supports NuBus ethernet cards via a PDS to NuBus adaptor card. That style can't be used in the SE/30. So double the cards before you buy yourself the wrong card. (and BTW: I've seen the SE/30 cards on ebay for around $10.00) -chris <http://www.mythtech.net>

Garage sale, DEC 3000/500 $50, HSZ40 $25, ...

by gschadow＠regenstrief.org

Am I crazy to sell a DEC 3000/500 server (desk side) for $50? I believe it's got all the RAM it can fit and disk in and lots SCSI plugs out. My HSZ40s go for $25 a piece. My HP9000K400 with 2xDDS2 drives and 30 GB (?) RAID array and HP Terminal all in one rack go for $100. Am I crazy or just fed up about stuff taking space in my garage? If you are in the Indianapolis area and want to get some stuff, go for it as long as supplies last. -Gunther

VAXen available.

by cmcmanis＠mcmanis.com

A number of VAXen are available this week from www.auctionbdi.com. I gave them all of my "spares machines" which I cannot store and no one in the Bay Area wanted. The good news is that BDI will ship them to you pretty much anywhere in the country and the minimum bid is $25. The lot to look for has 3 MV3400's (in BA213 cases), one VAX 4000/300 (in a BA440 case) and one MicroVAX II in a pedastal BA23 case. I don't recall how complete they are, I do thing the 4000/300 is complete except for some DSSI plugs which I needed to bring my 3800 on line. Two of the 3400's have the front "door" (one says MicroVAX 3400, one says VAXServer 3400). If you've got a 3400 or 4000/300 there are plenty of parts to "enhance" your system. I believe the 4000/300 has 192MB of memory but can't swear to it) There is also a MicroVAX 3600 in a H9644 rack. This one I've never looked at in depth other than to note that it has a 4 SCSI drives and a tape but a gap where the SCSI controller had been. Given that it couldn't talk to the disks I pretty much ignored it. Finally there are some PC parts with a nice 17" NEC 5fg monitor (including the special NEC VGA cable). The monitor is nice but not an "Energy Saver" (it stays on as long as power is applied, no standby mode) Probably not of interest to this crowd but I thought I would mention it. --Chuck

Help! need 400k/800k Mac os 6 or 7 diskettes!

by cb＠mythtech.net

>btw I can't seem to get www.mythtech.net... is it up? >it could just be the Nameserver I am stuck with. Its up now, it was up when I tried it. So maybe it was down and fixed itself, or maybe there was a failure elsewhere. Feel free to try again. -chris <http://www.mythtech.net>

Betr.: Morely Electronics Teletext Adapter.

by e.huininga＠sozawe.groningen.nl

The users guide can be downloaded here: http://www.retrocomputing-world.com/biblio/computer/acorn/doc/MorleyTeletex… Furthermore you could check http://www.8bs.com/ and The BBC lives (http://www.bbc.nvg.org/ ). The latter should have an archive of ROMs, which almost certainly should have the ROM for your adapter. Cheers, Eelco >>> Tony Duell <ard(a)p850ug1.demon.co.uk> 10/05 7:24 >>> While looking for Econet bits, I found the above-mentioned unit (Morely Electronics Teletext Adapter). It's clearly a BBC periperal. On the back is Belling-Lee coaxial socket (standard TV aerial connector), and a piece of 6 way ribbon cable. This splits, 4 wires go to a 20 pin 2-row IDC header socket (presumably BBC User Port, the connections would then be +5V, Ground, and 2 lines for I2C SCL and SDA). The other 2 wires go to a plug to fit the BBC's power outlet socket, to get 12V. Inside there's a single PCB with a TV tuner module mounted off one edge. The PCB contains a TV IF strip, CITAC (Computer Interface for Tuning And Control) chip (to select the TV channel under computer control), and a standard Teletext chipset (SAA5240 based IIRC). Does anyone know anything about this unit, and more importantly, anyone know where I can get the software to use it (it's certainly not compatable with the Acorn Teletext unit). -tony
