The hard drive is a proprietary connector, but you can build an adapter or purchase one ready-made (see the FAQ). The Mac Port needs power to boot. That power has to come from either the 6v LA battery or the 9v. The 9v needs to be in good shape though. To use the 9v, remove the cover to the big battery compartment (the cover trips a switch when it's in place). --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Is the mail Lead-Acid battery any good? If the battery is discharged or shot, the computer won't power up at all. This may be your problem. I believe it is a 6V battery. If I'm correct, then one out of a power wheels thing should work to find out if it's a battery, or a bad computer. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 ---------- > From: Marion Bates <Marion.Bates(a)Dartmouth.EDU> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Mac Portable problems (was Re: Mac Portable batt charger) > Date: Thursday, August 20, 1998 3:19 PM > > I checked the backup battery and it read 8.7 volts or something, which I > figured was adequate...maybe not? > > > -- MB

Not that I know of. TSC went under some years ago; we all assumed that it took the source to its grave. Rumour has it that some former employees of TSC *may* possess some sources, but they have not stepped foreward. FWIW: A co-worker of mine was approached some years ago with an offer to sell the FLEX sources. My co-worker wasn't interested, and the guy went away. Don't know who he was. For all we know, it ended up in the dumpster. :-/ Jeff At 02:33 PM 8/20/98 -0500, you wrote: > >< For years, it was *THE* disk operating system if you had a 6800/6802 bas >< system.

Hmmm... Seems that if a Mac Portable battery is dead, you cant power the machine even with the AC adaptor. I'm certain this has something to do with my problem. It also seems that if the Mac Portable battery ever gets discharged below 5.4v it becomes a doorstop. Tony

MCA ethernet cards

by rhblake＠bbtel.com

Still in need of a few microchannel (for PS/2) ethernet adapters with the BNC 10base2 setup. Doesn't matter if they have AUI or RJ45 with it as well, as long as it has the BNC/10base2 setup. I don't need 3270 cards so check any cards you think you have with the BNC connector to see what they are. Looking for donations, trades or reasonable priced cards for a parochial school network project that's overdue. I've gotten a few good reponses and have a couple on the way but I'm going to be about 4 or so short yet. I've also gotten one or two ridiculously high quotes for used cards. This is a project on a shoestring budget so no $30 or $40 cards please. Russ Blakeman Harned, KY USA

Kaypro 4 for trade

The machine itself is complete and working but I do not have any diskettes for it. On power up it displays a "please insert system diskette in drive" type of message. Per my previous postings I'm mainly interested in calculator stuff (and have a detailed "want" list on my Web site). Please write me directly if you have any interest in this machine.

It is "Computer Structures: Readings and Examples" by Bell and Newell. It uses strange notation (for me) and even the table of contents is "virtual". Anyway, it includes descriptions of 2 desktop calculators, both about 1968: an Olivetti 101 (USD$3500) and a HP 9100A. The HP uses core memory, its program ROM uses 16 layer PC board technology. The HP article is a reprint >from the HP Journal. Does anyone have either of these? There are many other computers described, both common and uncommon. Some are valved, such as the UK Pegasus, which was only 3 "bays" large. -Dave

They had many calculators, sometimes the last 2 digits in the model number = calsulator digits. I think the nmost digits I saw was 14, though. Also clocks, etc. In late 1974 their ads were for a 416 which was a 4 channel x 16 led "logic scope" Built in one of those black bakelite boxes. It sounds like one of those oscilloscope "multi-channel" adapters that were popular when CMOS multiplexers came out, like the 4051, but this one used led's instead of am external scope. -Dave

Cleaning RL02 Packs

by healyzh＠ix.netcom.com

Question of the day, how do you go about cleaning an RL02 pack. I'm not talking about the "Customer" cleaning that the user manual talks about. I'm talking about the "Dec Certified Tech" six month cleaning or however it was they put it (read it last night). The six month cleaning sounds like it includes cleaning inside the pack, which is what I"m interested in. I know someone, Tony I think, mentioned taking apart and cleaning RK05 packs. Well that's what I'm wanting to do with this RL02. It's called the pack is visably dirty inside, with a thin film of grim. Any suggestions, recommendations, crys of "are you out of your freaking mind"? Zane | Zane H.

Mathatron & other stuff

by aknight＠mindspring.com

Hello out there in classic computer land, I'm new to the list and wanted to introduce myself and my Web pages to the rest of ya'll. My name is Alex Knight and my Web page, the Calculator History and Technology Archive, is located at: http://aknight.home.mindspring.com/calc.htm My interest is primarily in early-model electronic calculators, but there are some crossover machines that seem to fit the bill as classic computers, and in my searching for old calculators I sometimes turn up some interesting old computer stuff. One of the more interesting machines that I have written an article about for my Web site is called a Mathatron, which was advertised as a desktop calculator/computer and sold as early as 1964. The Mathatron is a very large and heavy (24" x 24", 80 lbs) machine, but it will fit on top of a sturdy desk. I believe it to be the first programmable calculator, and some other people I've talked to consider it to be the first desktop computer (because of it's programmability, available peripherals, etc.). So ya'll take a look and let me know if you have any additional info. on this unit that I may be able to add to my article. Another "crossover" machine that I have a little info (mainly pictures) of is the HP 9830, called a calculator but in fact a computer with BASIC. Also on my Web site is a list of things that I'm looking for and things I have for trading, as I find classic computer items that I put on the trading block I'll send a message to the list to let ya'll know. Have fun, Alex Knight Hillsborough, NC

Charging batteries

by tomowad＠earthlink.net

I have an Outbound Notebook which takes a camcorder-style 12v 2 Ah battery. The Outbound's power adapter, which is used to both run the unit and charge the battery is 22v, 0.82A. Unfortunately, I don't have the adapter or anything similiar. What I would like to know is how forgiving the Outbound and its battery would be if I used an innapropriate adapter. I have an adapter that puts out 14v and 1.2 amps. Am I correct in assuming the 14v would suffice for charging the batter (not running the unit)? What about the 1.2Ah, though? Will the extra amperage do any harm? Thanks. Tom Owad P.S. Anybody have a 22v, 0.82A adapter for sale? -- Sysop of Caesarville Online Client software at: <http://home.earthlink.net/~tomowad/>

Speaking of New Aquisition....

by cfandt＠servtech.com

I got a VMS ver. 5.4 "Grey Wall" myself with the 'Great Haul' a while back. I took an inventory of all the manuals based on the first several pages of the Introduction to the Master Index (found in General User vol. 1) I discovered at least four binders are missing. Not too bad considering there seems to be a total of at least 29 grey binders in the whole of the three manual subkits. They probably were left on somebody's desk at the southern college from where the previous owner obtained my VAX 11/750 back in '90 or '91. Would anybody have just odd parts and pieces of the VMS 5.4 manual collection? If so, would any of you be willing to part with several to help complete mine? Here's the manuals/binders I'm missing: General User Subkit Volume 4, "VMS DCL Dictionary" (may consist of vol. 4A and 4B in one _or_ two binders as hinted by a footnote.) System Management Subkit Volume 3, consisting of : "VMS Access Control List Editor Manual", "VMS Audit Analysis Utility Manual", "VMS Authorize Utility Manual", "Guide to VMS System Security" all in one binder. Programming Subkit Volume 7A, consisting of: "VMS I/O User's Reference Manual: Part I" and "VMS I/O User's Reference Manual: Part II" both in one binder. Programming Subkit Volume 7B, consisting of: "VMS Delta/XDelta Utility Manual" and "VMS System Dump Analyzer Utility Manual" both in one binder. Later, I may ask for help in completing my RSX-11M ver. 4.1 'Orange Wall" when I get around to doing a precise inventory. Seems to be several of those binders missing. (At least my RT-11 ver. 4.1 manual set seems quite complete :-) ) Thanks loads for the help! Regards, Chris -- -- ======================================================= Christian R.

Will the extra amperage do any harm? I don't know the outbound, but I can offer the following thoughts: To charge a 12V battery with a 22V power supply suggests some internal regulation, in which case 14V probably wouldn't work. On the other hand, it probably would do no harm. You don't say whether the 22V is dc or ac - if it's ac, dc might work, but if it's supposed to be dc, ac could damage your machine. Most power adapters are constant voltage, and quote a maximum current. So the requirement is for 22V, capable of at least 0.82A. A power supply that can put out 1.2A (not Ah) would be ideal. > P.S. Anybody have a 22v, 0.82A adapter for sale? I could build you one, but shipping it to the US might be expensive :-) Philip.
