Doublespaced, iirc, with Win3.1 loaded. Memory is available, though not always cheap. I don't know much about the motherboard specifics though. >One Mac IIcx - what good about this one? The IIcx is a 68030 (I think!) but doesn't include the onboard video of the similar but slightly later IIci. It was introduced in 1989 at $4669 and discontinued in 1991 at $4699 (according to "The Mac Bathroom Reader".) --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Does anyone have information on a 4-bit microcomputer called the KX-33B . Back in 1979 , with the purchase of a Pet computer you could have received the kx-33b for free from Ancrona . Also I am looking for information on a programmable digital computer that NRI schools offered during the 70's . The front panel of the unit appeared to have sixteen rows of on\off switches for machine code entry . I am guessing that the kit utilized possibly a couple of 7489's for ram . Also any info on units that had similar 16x4 or 16x8 machine entry would be appreciated . thanks, Frank

Is there some special trick required to boot Fuzzball?

by DSEAGRAV＠toad.xkl.com

I have my 11/23 (The DEQNA isn't in it yet, it has RT-11 v5.04 on it, I kermitted over the distribution, followed the directions in in readme.txt, and did @sysgen. Then I had to go to class. (The 23 is at school) I came back an hour later to the . prompt (No error messages) So, I followed the rest of the directions, put everything on the DU0: (10MB EDSI drive on a QD21) and modifed BOS11 for my config (Commented the QNA driver, added RX02 lines as per the example in some other config), renmaed it to BOS1 and built that. No errors. Put that on the DU0: Now, I do RUN BOS1 and it sits there. Doesn't halt, just sits. It's been sitting 20 minutes, what did I do wrong? Oh, and I fudged, the drive is 120MB. I'm using MM to send mail, so I can't go change it. RT-11 seems to work just fine, btw. I boot from rt11XM normally, but to load fuzzball I did BOOT RT11SJ, then ran it. Not enough memory to do it under XM. Anything else I'm supposed to do? -------

No not quite, it was the first of the line if anything and early on to boot as I had it in my hands by January 15! Last was supposed to be list. < That's my point. The IBM was already being produced at that point and <being delivered shortly thereafter. Altair was still using the prototyp <machine and just starting to sell bags of parts as "kits". Keep in mind the cover of PE was composed and at the printer in in september-october 1974 time frame if not earlier to meet the publication schedule if it was to arrive in my home by mid December 1974!. I should point out that the 8080 by then had been in production about a year at that point. Allison

Paperclip (Was: Re: Free IBM system 36)

I've tried crossing the numbers on the ROMs and > can't learn anything. Does anyone have a schematic of a PET mainboard? 2732 on practically all PETs. Early ones (ROM=6540) had no spare sockets Early ones (ROM=2316) also had no spare sockets, but could take 2716 chips in place of the system ROMs Late ones (Model = 8296) had some sockets that could take 28-pin 2764s, but I think all the spare sockets were 24 pin for 2332 and 2732.

Free System/36

by Philip.Belben＠powertech.co.uk

> actually, what i meant by the power-user comment was a person who is > not afraid to use a black-and-white command prompt if it can help > him/her do something. So, would a System/36 be good for me? If you don't mind learning OCL (the minicomputer version of JCL) and typing all the // commands at the command line of a text only terminal (probably green rather than black and white :-) ) then yes, give it a go. But first find out what size it is. There were desktops (5364), desk side (5362) and huge monsters (5360) plus some others (odd numbers) (after my time). The 5360 had a version of my favourite diskette drive, but I have spouted at length on this list about this in previous posts... Philip.

<was in full production and delivery while the Altair was still deliverin <incomplete bags of parts and even those were months behind. In fact, mos <Altair "kits" were delivered in installments spread over almost a year. Y <got parts for one section at a time. I DO have that ad handy. I shoul <scan it and post it. As some one that built ans has one... MITS offered the kit of the month as a way to get Altair into the hands of people that couldn't cought up $1000 at the front. I was doing engineering at the time and making a good buck with out marriage so it was doable and I had mine in about 4 weeks after the order (took UPS 10 days to deliver it then!). I may add it arrived on a tuesday and I used my evenings to set up for assembly and that weekend I started soldering and didn't stop till sunday night when first powerup occured. I had a working machine. Three weeks later I would get docs listing some 10-20 mods to make it more reliable! FYI the SN was in the 200 range. Now the much better IMSAI machine was nearly a year later in arrival but was actually better developed and a far more reliable design from the first. It was a marker machine as it also used S100 bus making it the Polymorphic -88 and the SOL-20 amoung the first to use the same bus and the swtp-6800 started the ss50 bus. Back then an open and standardized bus was a advantage to the person that owned the system and they werent locked to one vendors board and the price competition was fierce. By 1978 memory board were denser (8k static vs 4k dynamic) and half the price of the boards from MITS (88-mcd was ~400 for 4k). Allison

< He's got to be thinking of the HP 9800 series. I'm not sure when the I gotta get that sex change. It happens it's MS Allison and I don't have the problem of the wife objecting. Anyhow 9800 series it was most likely as when I'd seen it it was not new and I was doing 8008 design when that part was $180 each! Allison

SMS 1000 aka PDP-11/73

by healyzh＠ix.netcom.com

OK, I've powered on both of the systems with the PDP-11/73 processor boards in it. I now know that they are apparently "SMS 1000" machines, but I've been able to find nothing on it on the net, except for a web page that has a picture of one in a 'tower' case http://staff.motiv.co.uk/~kevan/collection/manufacturer-sms/1000.html Mine is in a rack mount case though. It has 5 buttons and a small alphanumeric LED display that gives some system info when the system is powering up. I'm quite honestly not sure how to proceed. I've connected a laptop running TELIX for VT100 emulation. This gave me some trouble initially, but it started working once I added a "Null Modem" adapter I had (trust me you don't want to see the console cable I put together with three adapters). The display and buttons are layed out like this. +-----------------------------+ | DISPLAY | +-----------------------------+ +------+------+------+------+ | MENU | < | > | * | +--+---+---+--+---+--+---+--+ | RE | RUN | WRT | | START | HALT | PROT | +-------+------+------+ On the one with the 5.25" floppy I get the following when it comes up. SMS 1000 BOOTSTRAP 256KW MEMORY 11/73 CPU BOOTABLE DEVICES: DEVICE DEVICE UNIT NAME TYPE NUMBERS DU DSA 0-15 MU TK50 0 MS TS 0 ENTER DEVICE NAME AND UNIT NUMBER: AUTO - BOOT BOOTING FROM DEVICE 0 ***THIS VOLUME DOES NOT CONTAIN A HARDWARE BOOTABLE SYSTEM *** 000034 @ On the one with the 8" I get HELLO MIKE BOOTSTRAP 256KW MEMORY 11/73 CPU BOOTABLE DEVICES: DEVICE DEVICE UNIT NAME TYPE NUMBERS DU DSA 0-15 MU TK50 0 MS TS 0 ENTER DEVICE NAME AND UNIT NUMBER: AUTO - BOOT BOOTING FROM DEVICE 1 BOOT-U-CI/O error 000724 @ I played around and they both appear to default to the correct device numbers for Hard Drives. It gives me a *** DEVICE NOT IN SYSTEM *** if I try to access MU0 or MS0. Well, MU0 is no surprise, I know it doesn't have a TK50 in it, but I've no idea what the TS is, or how I would, or if I could boot from floppy. The 'C' in BOOT-U-CI/O error is actually a wierd c like character with a little squiggely under it. I'm assuming the first simply doesn't have an OS, and that the second has some sort of hardware problem, most likely a dead Hard Drive. I've tried to ensure that all the connections on both are good. I've learned that typing in 173000G at the @ prompt will get me back to the "ENTER DEVICE NAME AND UNIT NUMBER:" and that I can then specify a device instead of letting it go with it's own choice. Does anyone have any suggestions as to what I can do at this point? I'm guessing not much until I can scrounge an OS from somewhere. Is it possible to attach the RL02's from the /44 and see if I can boot off of those? What kind of a card does it take to interface with a RL02? Zane | Zane H.
