Or how about Sega Megadrive or Amiga CD32 pads?? I know it would depend on which pins were used for button and direction detection but they might work... I hate using joysticks these days.

Transformer question (only slightly OT)

by cclist＠sydex.com

I have a power transformer that I scavenged out of a 15-year old UPS, so it's probably pretty close to being on-topic. At any rate, I want to use this transformer in a DC power supply. I have three sets of windings: two sets are 120/240v "universal" series/parallel type and the third is 24-0-24v center-tapped. I want to run this from 120vac. Is there any benefit to paralleling the two sets of 120/240v main windings (i.e. 4 120v windings in parallel)? Will it increase the power rating of the unit or is that mostly a function of the secondary winding? Suppose instead of 24-0-24 on the secondary, I'd like 12-0-12. Obviously, one way to get this is to hook the primary (-ies) up as 240v. Is there any benefit to be gained in parallelling the two 240v primaries? Thanks, Chuck

sunos install docs?

by brad＠heeltoe.com

Does anyone have sunos install docs for 2.0, 3.5 or 4.0 on a sun2? for grins I tried the sun2 emulator with the sun2 tape images I found. I made some guesses about copying the miniroot to the swap parition but could find no joy. (that's a joke, heh, with appologies to bill) I could get the 2.0 tape diags to run and put a label on the disk but running the standalone copy to copy the miniroot to the swap (which I assume is sd(0,0,1)) did not allow to boot - it just took an exception. none of the other tape images (3.5, 4.0) seemed to work. the boot would run but the standalone copy an diags would crash. -brad

There were really many Yasbc(s). ;) Yes, it was described in TCJ years ago. It was on eurocard with their nice connectors. I have one I did using a section ISA16 bus and ISA 16 for IO, DISK and herc mono video. It was a hexperiment. ;) Allison

Minimal KDJ11 system

by dbetz＠xlisper.com

I am about to drastically cut back on my collection of PDP-11 hardware. After giving away everything on the list posted in another message, I will have the following QBus boards left: M8192 (KDJ11-A) M8059KF (128KW RAM, two) M8047CA (boot, serial, RAM) What I'd like to do is find a small QBus backplane and power supply that will accept these four cards and then use the TU58 emulation software to boot RT-11 over a serial link to a PC. I understand that this will be slow but most of my work with PDP-11s so far has been with the PDT-11/150 and its floppy drives are very slow. Maybe I'll feel right at home! In any case, does anyone have a small QBus backplane and power supply that they are willing to sell or trade?

OT/OT Software??

by jim.isbell＠gmail.com

I am cleaning up and found some old software on 5 1/4" floppies. I was going to put it on Ebay but occured to me maybe someone on this list would be interested in it. But I am almost afraid to speak since it may be Off Topic? Jim Isbell "If you are not living on the edge, well then, you are just taking up too much space."

Data General AV/10000 worth saving ?

by dm.hunt＠ntlworld.com

I've heard from an NHS (UK public health) source that a Data General AV/10000 is to be scrapped sometime in the next six months. The guy laughed and choked at the list price, ?795,000 ... As far as I can ascertain, it has 32 x Motorola 88000 processors, a huge SCSI disc array and a lot of RAM (could mean anything) and runs a flavour of UNIX. But the whole thing has gone cranky (a technical term ?) and with NPFIT (National Programme For Information Technology) (a ?37 billion government IT project looked set to replace all IT in the NHS) the DG box will become redundant next year anyway. Is it worth rescuing ? Bear in mind I would probably have to pay the equivalent scrap value. It also sounds quite big too, I can't find any idea of the size on Google... There is also a AV/25000 going end of next year, I think that is too new for this list though (PIII Xeon), plus it's probably outside of my price range... Dave ;)
