Looking for...MSDOS OEM Adaptation Kit

by rcini＠msn.com

Well, another bee in my bonnet... I'm experienting with an x86-based hobby robotics controller, but I'd like to graft certain functionality onto old MSDOS (don't ask why), including a ROM monitor, etc. I remember that MS carried a special version of MSDOS for people who need to modify the code for specific hardware. Certain portions of DOS are provided as source and the rest as object code. Does anyone have a copy of this?

IBM 360 and 370 control panels available

However, the price for any "collectable" is what the buyer and seller negotiate. That's why you need to contact Data Sales for asking prices, and then decide whether you want to make a counter-offer. They've been listing prices and minimum bids in their eBay offerings. However, you will note that few people are bidding on things, and Data Sales has a lot of "headers", TCM's, etc.. On the other hand, Jim at Data Sales is aware of the 360/50 control panel that sold on eBay for considerably more than $500, so that may raise his idea of what his inventory is worth. Note that I've very uncomfortable discussing prices like that for computer equipment. My motivation for acquiring what I've got is emotion (affection, nostalgia, respect for those 1960's engineers, etc.) and it feels icky (technical psychology term) to put dollar values on that. However, much of this stuff wouldn't exist if someone hadn't salvaged it, transported it, warehoused it, etc. I think that those people are entitled to reasonable compensation, and again, "reasonable" is defined by negotiation between buyer and seller. -- John

More on the RCA Studio II

by ethan_dicks＠yahoo.com

I know it's bad form to reply to your own posts, but here it is. --- Ethan Dicks <ethan_dicks(a)yahoo.com> wrote: > > Today I finally picked up an RCA Studio II home video game... > ...it uses the RCA 1802 processor (and the 1861 video chip). > > Does anyone out there have any pointers to internals information? I just opened it up... some previous owner has scrawled lots of notes in pencil about what does what. Address lines labelled, component symbols (on the solder side), memory address ranges, controller key numbers... Lots of good info. The board itself resembles the Quest Elf in its layout style - lots of room and waves of curved, parallel traces. Outside of the RF cage are the CDP1802CE, an RCA TA10171V1 (the video chip), four 1822 256x4 SRAMs ($0800 - $09FF), four 1831 ROMs (512 bytes each) [$0000 - $07FF] and the glue logic: one 4042, one 4001 and one 4515 (which I think is the latch for the game controllers). The timing and power section is a 555 and a 7805, pretty pedestrian stuff. The date codes suggest a timeframe of 1Q77. The ROM carts use a .154"-spacing single-sided 22-pin connector, so RatShack has boards I can use to make my own. It's just stunning to open this up and have this kind of documentation in place. The 1802 is a simple beast. This guy obviously did what I was going to do - start with the known CPU signals and work out. What I _wasn't_ planning on doing was marking up the original. I'm glad he did. One odd thing about this design - DC power come into the RF switchbox that clamps to the TV. There is a single RCA cable that connects the switchbox and the game unit. It appears as if power goes one way down the cable and video data goes the other way. Strange. -ethan ===== Infinet has been sold. The domain is going away in February.

New find: RCA Studio II

by ethan_dicks＠yahoo.com

Today I finally picked up a device I've been searching for since I was a lad - an RCA Studio II home video game. It is especially precious to me because it uses the RCA 1802 processor (and the 1861 video chip). Does anyone out there have any pointers to internals information? I'd love to pull the ROM and disassemble the code, but with no idea of which I/O port the video is on nor how the game controllers are interfaced, it makes reverse engineering the code more difficult (of course, knowing what the code does can make reverse engineering the *hardware* much easier ;-) I'm also interested in picking up any game cartridges for this thing. I've seen a few, here and there on the web. I can probably find some with Altavista, but I thought I'd check here first. Enjoy, -ethan ===== Infinet has been sold.

Tube experts! - I T WORKS!

by dylanb＠sympatico.ca

ITS WORKING!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Special thanks to Tony's idea of hooking up an isolation transformer (6.3V but rated to 3000V).. Okay, I did some of Christians tests and I found that the Transformer indeed was arching into the main supply. (I won two of these scopes on EBay). Here is the funny part.. I rarely go into surplus stores but tonight I made an exception. I told the guy at the counter what my problem was and he had a box full of 6.3Volt isolation transformers rated to 3000KV HAHAHAHHAHAHAHAH.. I could not believe it. I bought a few and tried one out. The scope now has a perfect trace. On XY the dot is crisp and very stable. I have to align the scope.. but will do so after I get all brand new tubes in it. Second funny part, As I was leaving the store I went over to his lightbulb section (get the hint yet).. Yes, brand new bulbs [equivs] for my 8/S and my 8-I still in the package! What a day... I can't wait to get spacewars up and running. Thanks for the info Chris and Tony, I have one more scope to restore and have placed orders for another 8 of them... so I have some serious tube work over the next couple of weeks.

An odd request...

I just had a kind of odd request. This one's for the Apple gurus on the list: Is it at all possible, through hardware, software, or 'other,' to read 5.25" floppies written on an Apple IIe on a PC? Taking that one step further: Has anyone heard of the word processing program 'Zardax,' and if so, do you know if it's possible to convert its files to a more common format? Thanks in advance. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.

OT: Need PC MB help!

by edick＠idcomm.com

It's quite possible that the cache supply voltage and the main memory supply voltage were set to different values while the board didn't know that and hooked them together. I did that about 5 years back. That same mobo used a cache simm which could be plugged in backward. That wasn't good either. Trying to fix the thing will take a lot of time and won't yield results worth having. Best to follow the suggestions below.

OT: Need PC MB help!

by siconic＠jasmine.psyber.com

DAMN DAMN DAMN! I'm putting together a PC for my nephew. Everything is going fine, then KAPOW! A power transistor on the motherboard blows. I have no idea why. All I know is the last thing I inserted before it blew is the cache RAM DIMM thingy that goes next to the Pentium processor (at least that's what I think it is). Anyway, I have a bad pentium MB that I'd like to use for parts. The transistor that blew is HB1084 5C (what is that?) The one on the salvage MB is D45H2A. Are they compatible? I'm hoping one of you electronics gurus can help me out. I have to get this system rady cuz Santa's got to deliver it tomorrow. Any help will be greatly appreciated and will be rewarded with amazing amounts of karma!! Please reply to sellam(a)siconic.com.

Something went wrong to blow the transistor. The transistor became a fuse. Replacing the transistor doesn't fix the problem. When the second transistor blows, you will receive enlightenment. - John

Info wanted: Wilson Laboratories TX-1200

by rigdonj＠intellistar.net

Does anyone know exactly what this is? It appears to be some kind of a tape drive tester. It has switches for 7 vs 9 track, PE vs NRZ, single or dual gap, six different block sizes, six different speeds, FWD and REV and lots of test points and status indicators. I picked it up in a load of stuff from NASA (first picture). It has three ribbon cables that terminate with sockets for card edge connectors. One is marked "Read", one is marked "Write" and the other is marked "Control" (fourth picture). Here are some pictures: "www.intellistar.net/~rigdonj/misc/tapecase.jpg", "www.intellistar.net/~rigdonj/misc/tape-opn.jpg", "www.intellistar.net/~rigdonj/misc/tape-rt2.jpg", "www.intellistar.net/~rigdonj/misc/tapeconn.jpg", "www.intellistar.net/~rigdonj/misc/tapetst2.jpg".

To anybody & everybody who needs 8" & 5.25" floppy disks.

by netsurfer_x1＠hotmail.com

A recent trip to an office supply store turned up boxes of 8" & 5.25" floppy disks. Two of the 8" disk boxes (original IBM!) are opened, one is almost full, the other only has 1 disk in it. There are also 4 or 5 other boxes of disks (3M) that are *still factory sealed* They also have many boxes of 5.25" floppies, some are opened, & come in a variety of different manufacturers. Here is the Phone #, E-mail, & address of the store where I found them: Address: Hengst Printing & Supplies 155 West Travis La Grange, Texas 78945 Phone Number: 1-800-468-1270 E-mail: Graphtex(a)aol.com Better act fast! Because when the disks are gone, they are gone! ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

IBM 360 and 370 control panels available

by dylanb＠sympatico.ca

"NOTE--These panels are from machines that have already been scrapped, many more than two decades ago. I too would have liked to see these machines in running condition, but given their size, power and air conditioning requirements, etc., I doubt that there would have been very many takers." Your kidding me, right? I am partnering in with someone on this list to restore/sell the next 360 I get and I and my partner have received *very* serious offers. Please e-mail if you ever find any 360/1401 parts. I am sure to need them. john http://www.pdp8.com/

The Computerist's Video Plus board

by jlewczyk＠his.com

I just dug out an old single board computer which was made by a company called "The Computerist" which is called a "Video Plus", probably around 1981-82. Its a 6502 based board with the same form factor as the Kim-1 and I believe the same pin outs on the two 44 pin edge connectors. It has some 6522 vias and some video signal generating chip, a composite video output, sockets for eprom, four 2114 ram, etc. Does anybody have documentation on this board? I lost mine years ago when I sold off my old KIM-1 stuff :-( and would like to resurrect this board. Its in very good shape, but is missing some socketed chips. Need docs though to get anywhere. Any leads would be appreciated, even a contact to someone who ran the company or worked there could help. They had a lot of neat products! The COMPUTERIST, INc. P.O. Box 3, S. Chelmsford, MA 01824 Thanks! John Lewczyk jlewczyk(a)his.com

new addition: modified <?> PCjr <!>

by SUPRDAVE＠aol.com

in addition to getting a very clean PS2 80 and 65, i found a pcjr with strange modifications. a switch was added to the front of the jr that says: OFF/ON PC MODE. the computer sits on top of a case that's about XT form factor and it is called an EXTEC 1. It appears to have a hard drive, serial port and RJ11 jacks on it. a wide cable connects the jr to the extec. the jr also has 3 carts; one is jrVideo by pc enterprises, the second is pcjr clock cart by integrity tech, and one that says hardbios jr by MSC (HDD BIOS routines for the jr and RIM HD system it says) . also got an adaptor made by synetics sw and systems that allows two carts to plug into one cart slot. havent tested it yet since it rode home in the back of the truck and needs to acclimate to room temp before testing.

MicroVAX 3 Question

by allisonp＠world.std.com

<OK, question of the day, how many RAM boards can a MicroVAX handle? It's <living in a Sigma Rackmount chassis. You have three limits. Available power, max address space and Q/CD slots. I cant tell you home many Q/CD slots you have or how much power. The max address space for the Microvax depends on version. So you can in many cases run out of addressable space if the other two parameters are not a limit. Microvax1 4mb (Q22 limit) MicrovaxII 16mb (implementation limit) MicrovaxIII/Cvax (32 or 64mb I forget which) Allison

Is it something as simple as current/voltage, or does the bios actually have to receive some kind of recognizable signal >from the keyboard? I have a vintage ThinkPad that doesn't like my external keyboard, yet it works fine with other external keyboards that I've tried. Mine works fine on another system...

Oldest machine I've ever seen for sale...

by f.bonomi＠agora.stm.it

It seems that nobody has noticed that on ebay is going for sale an IBM 604 calculator. This is the oldest electronic machine I've never seen for sale, and if it weren't for an ocean dividing me and it... The IBM 604 was launched in 1948, and kept in commerce up to about 1953. It's about 2000 pounds total, 1400 tubes, a programmable calculator reading programs out of an punch reader (offered in this sale). There is a specimen of this machine at this dutch computer museum, with a photo of the little thing: http://www.wins.uva.nl/faculteit/museum/604.html This is how IBM depicts the 604 in it's own history: http://www.ibm.com/IBM/history/timeline.nsf/products2 The specimen on ebay has the 521 card punch/reader. This is the description of the seller: >IBM 604 weights 1300 pounds. LxWxH 52 1/4" x 31" x 60". >IBM 521 weights 740 pounds. LxWxH 41" x 25 1/2" x 50". >They require 220 volts & draw 36 amps running & 30 amps >at idle. These 1950s era EAM machines have around 1,000 >glass tubes & will heat up a room quickly. Sold as is, >may not be complete, some manuals but no parts catalogs. >This pair probably has not been used in 20 years. I repair >IBM card punches but not these babies! The machine is in Santa Fe, Texas, and the current bid is $224, ridiculously low if you consider that a single IBM tube of that series has been sold for up to $170 on ebay, and there is one currently going for $50. There are 1400 of them in the machine, and if somebody here does not act I am afraid the machine will be bought and cannibalized to sell pieces! There is still 1 day, 5 hours to the sale close! This is the ebay URL: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=219958046 Ciao Francesco Bonomi (from Italy) PS please let it be clear to anyone that I am not the seller; I just would like to be the buyer, but I can't becaus of obvious distance problems!

DEC/Compaq Collection arrives!

by spicer＠computerhistory.org

Hi Everyone! Just an update on the great DEC/Compaq collection that arrived last week >from New Hamsphire. Over 90,000 lbs of historical DEC hardware arrived thanks to a generous grant to cover shipping from Compaq. Mike Zahares of TransTech, our North American Van Lines agent, did his usual brilliant job of making sure everything was handled with kid gloves over the 3,000 mile journey! Thanks to the many volunteers who helped in the receiving of these rare artifacts, they now have a permanent home (the artifacts, not the volunteers! Although some volunteers _do_ seem to live here!) :_) Special thanks, therefore, to: Lee Courtney, Bill Pitts, Bobbi and Steve Rabinowitz, Charlie Pefferkorn, Jake Feinler, Mark Schaeffer, Ron Mak, Rob Shaw, Ken Sumrall, Al Kossow, Grant Saviers, Joe Frederik, John C. Green, Sam Ismail, Mike Baxter, Eli Goldberg, Ed Thelen, John Francis, Wayne Chin, Bob Joslin, Thomas J. Ackermann, Mike Zahares, Len Shustek, Mason Brown, Bud Warashina, and LaFarr Stuart. Forgive me if I have forgotten anyone! And History Center staffers Karen Mathews, Wendy-Ann Francis, Jack Hotchkiss, and Chris Garcia all pitched in and made sure the project went off without a hitch. Without all the hundreds of hours of help from these volunteers, who believe so firmly in the preservation of computer history, we could not have done this! Pictures of the arrival are available at: http://www.computerhistory.org/events/latest/ Note: photos of actual machines will be posted at this same URL on or about January 13th so check back then--we are creating a new exhibit on the DEC contributions to computing that opens to the public on that day! Thanks everyone for your support! Hope to see you at the Center or on-line soon... Sincerely, Dag. -- Dag Spicer Curator & Manager of Historical Collections Editorial Board, IEEE Annals of the History of Computing The Computer Museum History Center Building T12-A NASA Ames Research Center Mountain View, CA 94035 Offices: Building T12-A Exhibit Area: Building 126 Tel: +1 650 604 2578 Fax: +1 650 604 2594 E-m: spicer(a)computerhistory.org WWW: http://www.computerhistory.org <spicer(a)tcm.org> PGP: 15E31235 (E6ECDF74 349D1667 260759AD 7D04C178) S/V T12 Read about the latest History Center developments in "CORE," our quarterly on-line newsletter: http://www.computerhistory.org/events/core/1.1/
