Earlier today, I had Mintaka (Cromemco System Two) opened up and had her cards pulled so I could write down an inventory of what all she has in her. I noticed that on the FDC16 floppy controller, there is a wire plugged into a 2 pin connector on the card. The other end of the wire is not connected to anything. Any idea what it is supposed to go to? Here is a picture of the wire and connector in question... http://www.oz.net/~otter/Geekware/What-is-This-Connector-0.JPG I also noticed that the TU-ART card has a similar 2 pin connector, with nothing attached to it. http://www.oz.net/~otter/Geekware/What-is-This-Connector-1.JPG Is that where the other end of the wire is supposed to go? And if so, what about that connector in the middle of the wire? Thanks -- Scarletdown

Heathkit H-8

by chris＠blackwidowguitars.com

Hi, I have a Heathkit H-8 of which I know nothing about. I am curious to play with this machine a bit but really I don't know where to start. I believe all I have for the H-8 is the computer - the part with the keypad & led display & a bunch of cables. What can I do with this? How can I test to see if it even works? Any ideas where I could go to find more information about it? Thanks all! Chris Lamrock

OT: Clean steel? more info

by mmcfadden＠cmh.edu

More info for Sellam http://www.geocities.com/darrenmilford/scuttle.html Bayern as raised in 1933. She fetched a scrap value of ?110,000 nearly half of which was profit. The salvage operations on the various ships started in the early 1920's with most of the ships having been raised by the late 1930's. Since then fragments of ships have been raised and since Hiroshima they remain an important source of quality radioactive free metals necessary for certain types of sensitive scientific instruments http://users.accesscomm.ca/shipwreck/index7.htm Radioactivity in the atmosphere has increased over time with the continual testing of atomic bombs of all types. Steel makers need vast amounts of air to make steel so it would follow that steel made nowadays contains certain amounts of radioactivity. Prior to dropping the first A bomb in 1945, steel was radioactive free, and the only source of this 'clean' steel left lies in pre 1945 wrecks that lie on the seabed. Mike

OT: Clean steel? additional ramblings

by mmcfadden＠cmh.edu

Sellam Ismail was asking about "clean steel", here is some of what I know/remember from one of the applications that require it. The trace amounts of radioactive "stuff" in the new steel can swamp out the radioactive particle counters on some experiments. There was an experiment at the University of Missouri to look at the muscle/fat percentages in humans and in cows. There was an especially built building made from "old battleship steel" that enclosed the radioactive particle counter. The "experimental subject" was given trace amounts of radioactive potassium which would be incorporated into their muscle. The entire subject was then placed in a whole body detector to determine the percentage of the body mass that was muscle versus fat. I heard that they had gotten the steel from an old sunken ship. may be entirely myth Thanks Mike

RICM's ZS-1

by pat＠purdueriots.com

Just wandering around the web last night, and I was wondering 'what happened' to RICM's Astronautics ZS-1 ... has it yet been powered up, booted and put through its paces? While I was at Astronautics with Merle, (and everyone else), it looked like a fine machine that would be fun to play around with once it got up and running, and, well, I was just curious if it's been set up and successfully ran any software since it was moved.

I'm inclined to agree that this photo is from the US, but of course the majority of cars in Europe have the steering wheel on the left hand side of the car. If the UK is anything to go by, there are lots of satellite dishes there too...

Need Help Identifying Mystery S-100 Card

by SecretaryBird＠SoftHome.net

If I provide pictures and a descriptions of the various chips, would anyone here be able to help me identify this S-100 card? First, the pictures: http://www.oz.net/~otter/Geekware/Mystery-Board-Front.JPG http://www.oz.net/~otter/Geekware/Mystery-Board-Back.JPG The largest chip is marked: AM9513PC 8148HP (c) 1980 AMD. To the right of the DIP switches are 4 socketed chips... The two smaller ones: F-74LS136PC 7935 Singapore The two larger ones: 74LS244 PC F 8226 Indonesia The other 9 chips, in no particular order... F-74LS368PC 7918 Indonesia SN74LS00n QQ8130 (has Motorola Logo) 74LS02 PC 8221 Singapore F-74LS32PC 8210 Indonesia 435 DM7476N 74LS14 F 8248 Singapore 2630 937 (has Hewlett Packard Logo) 4N26 240F Korea 4N26 231F Korea I'm assuming that this is a homebrew job. But before I make a decision on whether or not to stick it in Mintaka, or sell it, I really would like to know what this card is for. Anyone have any idea? Thanks -- Scarletdown

Wang 2200 web site and emulator announcement

by frustum＠pacbell.net

Hello one and all. For the past three or four years, I've actively been looking for a first generation Wang 2200 computer. I actually have two now, mostly working. Over the past couple of months I acquired/developed all the technical information I needed to write an emulator. The emulator is far from complete, but it is quite usable. Besides the emulator, I've overhauled my Wang web site and added a lot more content. Now that the ball is rolling, I hope to maintain it more actively. The web site: http://www.thebattles.net/wang/wang.html The emulator: http://www.thebattles.net/wang/emu.html The emulator runs on win32 platforms right now, but I wrote it using a GUI/system abstraction toolkit, wxWindows, so it should be pretty portable to unix/linux/mac at least. If you have no nostalgia for the 2200, why is it interesting anyway? The first generation came out in 1973. Because it was designed before microprocessors were available, it is a microcoded TTL box. In many ways, it can be compared pretty fairly to home computers that came five years later. Because it predates Microsoft, it has a rich and quirky BASIC dialect. Unfortunately, I don't have any Wang BASIC documents online yet, but I do have a quick comparison of Wang BASIC vs early Microsoft BASIC. ----- Jim Battle == frustum(a)pacbell.net
