I think >the product name was SupRMod or SupRMod ][ or something like that.... If you want to be Captain-Nitpickily accurate, it was called Sup'r Mod, and the supplier's name was Marty Spergel -- the guy who first made himself famous at the Homebrew Computer Club by GIVING away an Intel 8080 chip. ("*gee!*") It wasn't that "Apple could not get FCC certification for an RF adapter," but that they knew darn well they didn't want to, because it would have slowed things up, cost a lot, and maybe forced design changes. Independent certification for a third-party RF modulator was much easier and cheaper. So the ]['s went out with advice to the customer that they did NOT meet FCC spec, and that if interference was encountered, it was the customer's responsibility to interpolate a proper device. I suspect Apple actually subsidized the certification of the Sup'r Mod, and everything after that was gravy -- Apple got off the FCC hook, the ][ stayed cheap to build, and Marty sold a g'zillion Sup'r Mods and got modulatedly rich. __________________________________________ Kip Crosby engine(a)chac.org http://www.chac.org/index.html Computer History Association of California

Beginners Need Help

by photze＠batelco.com.bh

Hello. I'm not so much a classic specialist as a computer specialist, as I love both old and new computers. I'm not a proffesional, but do know BASIC, DOS and all other kinds of stuff which the fast-moving stream of technology has left behind, unfortunately. But anyway, I didn't know jack about computers in the early 80's, other than what the average Joe knew: Keyboard, commands, annoying. But since '92, I've been learning more and more. But I need a basic list of systems that are 1. Easy To Find 2. Important enough to draw attention. Thanks, Tim D. Hotze

Hard drive jumper settings required.

by dseagrav＠bsdserver.tek-star.net

I'm going to attach this to the QD21, so I need to reset the jumpers. IBM 115MB ESDI drive, type 0669, sequence # 104040108 There are 6 DIP switched behind the drive terminator. I'm told I have to use a straight-through cable, so I went and got one. The drive does nothing. With a crossover cable (Where the pins are crossed, a normal PC cable) it went click-clunk, click-clunk, and did nothing. The drive is known good. (I pulled it from a PS/2 which we upgraded to a SCSI drive) If anyone works at Advanced Technology Services, the drive came from Cat origionally and has the ATS sticker "ATS-444862" Another barcode on top of the drive by the air inlet says "B1AF3092241"

Need Jumper Settings...

by photze＠batelco.com.bh

Hello. As you may/may not know, I'm working to get a XT working; but I don't have to many of the origional componets. I have the origional XT's monitor and case, but my graphics card is by Multitech, mostly with Chips by a company called Chips (They made the graphics stuff in the IBM Thinkpad 365ED's.), and it's model number (I guess) is PB85101. It does have a composite video adapter on the end, as well as a monitor connection. There are two large processors identical in size and shape to the 8088 (but it probably isn't), but made by Chips. There is also a bus adapter, chips are also made by Toshiba and TI on this thing. It has EGA stamped all over it, so I'm wondering what I should do. Thanks, Tim D. Hotze

Spectrum case colour

by pjoules＠enterprise.net

Hi, I got a Sinclair Spectrum +2 at the weekend from a car boot sale complete with a light gun and in its original box with about 50 game cassettes for 20UKP. When I used to have one of these many years ago I seem to recall that the case was grey but this one has a black case. Does anyone know if they were made in different colours and, if so, what the significance of the colours was? Regards Pete #include <std_disclaimer>

Franklin Ace 1200

by healyzh＠ix.netcom.com

Well, I just powered up one of my finds this weekend. It's a Franklin Ace 1200, the amazing thing is I got it from Goodwill, and it came with a box of floppies, the CBASIC reference manual, and a monitor all for $14.95. Not only is it the best deal I've seen at Goodwill, but it's also the first complete system I've seen there. It actually has CPM 2.2 and some other software so I've finally got a fully functional CPM system besides the Commodore 128. Now what I'm wondering about is the character set. It looks really wierd, and has me wondering if there isn't some sort of problem with the video board. The best example is a capital B which looks like this ******* * * * * ******* * * * * ******* This is just one of the wierd looking characters this systems displays. On the other hand when it's acting like an Apple ][ with a 40 column display it seems to have a normal character set. Overall it seems to be a pretty nice system. When I picked it up I thought it was just a simple Apple ][ clone. It's ability to run CPM and having the original CPM disks was a really great plus. Zane | Zane H.

Commodore put their name on the board after they bought the company in October 1976. Before that date the boards have "MOS" on them after they have "Commodore". Hope this helps.

Help Identifying RAM Chips

by gzozman＠escape.ca

I have two original Compaq Portables, both of which are giving POST errors when they boot which indicate bad RAM. I have gone through a few rounds of swapping RAM chips between the machines to identify the bad chips, but have come up against a potential roadblock. My problem is that there are a number of different chips used in the machines. As I don't have any data books on these chips, I am not sure if the different numbers are simply different manufacturer's numbers for the same chips, if some of the numbers are simply date codes, or if they are really different, incompatible chips. If someone is familiar with these numbers, or can look them up for me, I would really appreciate it: Chip #1: Hitachi 1818-3006 Japan 8332U HM4864P-3 Chip #2: NEC 8539PF513 D41256C-15 Chip #3: Fairchild (I think; has an "F" with a bar above and below it) MB81256-15 8548 M79 BC Chip #4: NEC 8538PF532 D41256C-15 If you could let me know the size of each chip, as well as the width of the memory, it would help me determine what size of RAM I should be setting the motherboard DIP switches for. Also, would I be correct in assuming the "-15" appearing on most of the chips specifies 15ns? If anyone is familiar with adding RAM to the motherboard on the Compaq, I would appreciate your input on the following: The machine has 4 banks of RAM, consisting of 8 chips each, plus 1 chip for each bank marked "BIT 0". The first two banks of chips (0 & 1) are soldered, the other two (2 & 3) are socketed. 1) Is the "BIT 0" chip a parity chip? 2) Can RAM be installed in Bank 2 without having to populate Bank 3? Any help in regards to the above is much appreciated!! Thanks in advance.

Here's A Great Place for Surplus DEC

by mcquiggi＠sfu.ca

Hi All: For those close to Ottawa, Ontario, I've found a fantastic source of DEC boards and associated equipment: Computer Recyclers Inc. 10 Rideau Heights Drive, Nepean, Ontario K2E 7A6 Canada (613) 723-3135 Fax: (613) 723-4607 I've been to Ottawa 3 times in the past year (work related), and each time they've had HUNDREDS of boards, systems, cables, etc., tons of stuff from DEC and other DEC sites. They are recyclers, i.e. they feed dumpsters and metal recyclers, so prices are great. Dual height boards are flat rate $5 CDN, quad height flat rate $10 CDN. If you need boards, power supplies, backplanes, rails, racks, cables, drives, terminals, printers, etc then this is a good place to check. My finds from last week included 2 TK70 drives and a TQK70 controller for $25. Unfortunately the selection is largely hit and miss as they move systems through pretty quickly. There's currently no inventory, you have to show up and look through their oil drums of boards etc. I did, on my last trip, provide them with the "dec field guide" board inventory document, and suggest to the owner that they catalog and sell their boards on the net, but we'll have to see if they do so. For PC types, they also have some PC class stuff, mainboards, etc but I didn't really look at these. For info of the group, Kevin --- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca

Fido lives!

by photze＠batelco.com.bh

Well, that's okay if you needed to be wordy. It looks like the same story again: Intel stopped the Pentium at 200 Mhz, then AMD made a 233 Mhz chip, which benchmaked the same as the Pentium II at the same megahertz. Then this time, Intel went back and made THEIR 233Mhz chip, but it didn't even benchmark as high as the AMD 200 MHz. AMD's soupossed to be making a 266Mhz Socket 7 CPU, so that would combat most Pentium IIs, but not the 300Mhz. Still, 300Mhz benchmarks are only slightly higher than 266 as of the slow speed of componets. Well on the Compaq memory board, I would check with memory suppliers, not Compaq themselves. I'm using a Compaq, and when I go up to tech support, they say that they will have a "processing fee". Compaq ususally uses non-standard memory on their motherboards, for some strange reason. The Presario CDS 633 has a nice motherboard, as everything EVERYTHING is built in. 4 MB RAM, Video card, 2 IDE slots, 1 SCSI slot, parallel port, 2 serial ports, game port, everything except the componets and the sound card. But the memory is non-conventional for 30-pin SIMMS. Compaq claims that they're better, even though they STILL run at 70ns. The only added feature is that there are 16 MB chips avaible for them, not just the 4MB as with most 30-pin RAM. Hope that this helps, Tim D.

In that time when you knew about it, 33mhz was "THE top of the line" and digs up lot of $ from your moth-eaten pockets so you did not hear much about it but also some people knows about 33mhz but $$$ and Amd was busily cloning the 386 and was successful. Intel responded with massive cutting then short time later killed the 386 and made people buy up all those 486dx and 486sx. That leaves Amd's market to keep selling those 386 because they're still powerful enough and and they're dirt cheap at that point. 386 is a must in that past when running that dreadful and still is, windoze stuff. I had the uncached 386dx 25 (yuk) in '91, then had cached Am386dx 40 1 year later. Finally had my hands on that famed Am486-40 in '94 at aching $350 because of Intel's cost. Longest span since that until early '96 got the P word 100 also is breaking my record of owning that longest second to my 386sx laptop (still have it 4 years). Sorry to say, and now look what Intel is trying to dig Pentiums into dirt again while all kinds of 386 even gasp (!) 286 owners upgrading to P5 not PPro or P5II because they're priced RIGHT. Even highest end with 64mb ram option, 4gb, 200(h)mmx, and everything else barely breaks 2k CDN range and that includes monitor and Asus mobo, few s/w. Average upgrade cost is between 300 to 500. At a bare minimum intel went to 33mhz, I know as I have both the DX and > SX versions. Yes, it is true that Intel officically says so to protect that now famed low end part of 486 from being passed on in those oh old days...sensiable Intel indeed. But little known CPU set (yup it's a set!) is RapidCad and it's from Intel officially rated 33mhz but works well at 40mhz. What so, I have this set as well and what I know is pays to put the heatsink on that RapidCad 1 chip and leave the smaller one called RapidCad 2 bare. Large snip! Troll (this is my nickname of Jason D.) PS when I had problems I had to call to have RapidCad set replaced, their tech support gave me a BIG runround before they get me to correct dept to process properly. Not very easy and not fun especially when one is deaf like I am. The automated system speaks fast, relay operators that I work with could'nt keep up and get stuffed into "musical holds for live personnels" YUK! As a techie guy, I seen this often when calling for components ordering or assistance. But Web is very good "USUALLY"! And I still Kick Compaq for not releasing their much needed info I need even I offered to sign nda form! Any suggestions byond this? Info I need for those compaq SLT 386s/20 memory board module pinout and couple of resistors (smoked and no twin unit to refer to) in that SLT model no 2687 PS brick.

What your referring to is making one physical circuit look like multiple virtual circuits, aka networking. For PCs and minicomputers that is possible between each other but, not as a computer to phone line interface(caveats exist). For phone modems sharing it between phone lines is not an option. For BBSing you need one modem and one phone line for every user you wish to have on line at the same time. The modems do not have to be the same speed and even slow ones can eb useful. Allison

Corvus Concept

by kevan＠heydon.org

Hi, Last night I acquired a Corvus Concept CPU box and hard disk unit. Does anybody have any information about these? More specifically I am missing the monitor and keyboard and have no documentation on the specifications of these. They are both 9pin D connectors and that is all I know. -- Kevan Old Computer Collector: http://staff.motiv.co.uk/~kevan/

More specifically I am > missing the monitor and keyboard and have no documentation on the > specifications of these. They are both 9pin D connectors and that is > all I know. Well, I am sitting here looking at a little book with title HARDWARE DESCRIPTION THE CORVUS CONCEPT You might think that with a title like that it would have connector pinouts, but, um, not quite. Well, it does have the pinout for the bus slots, which are like Apple ][ slots less DMA support. So what can I find about video? The display area is supposed to be 560 x 720 dots. The monitor used by Corvus was a Ball HD series monitor (so says the manual) in a Corvus-peculiar case (so says me). It looks like all the timing is derived from a 16.364 MHz clock that is generated on the memory board. That gets divided by the "horizontal counter" (74163s at U202 then U203 and U204) to produce a 34.669 KHz clock that is the horizontal scanning frequency. There is also a "vertical counter" (at U301) to produce a 50 Hz or 60 Hz vertical sync clock. "The video shift registers comprise 74S299 U106, U206 and 74ls299 U306..U806 for video data. The data is shifted at 16 MHz in two pairs of registers. The output of one register is fed directly into a 74S157 multiplexer U104 which is switched between two inputs at a 16 MHz rate. The other register feeds a 74S112 flipflop U103 which delays the data by 30 ms and then feeds it to the multiplexer. This makes a data rate of 32 MHz." I'm not much of a hardware guy, but I hope that gives you some clues for board-tracing and monitor selection. Note that the system can run the monitor in either landscape or portrait mode (hence the peculiar case, with slots for the base on two sides). I think you are supposed to tell it how you've got the monitor positioned with the VERT/HORIZ switch on the back. That doesn't change the video timing, it changes how the software draws into the memory. Now what about the keyboard? I gather there is a 6551 UART at U310 that receives keycodes, one for each key-down or key-up. Key-down codes have the most-significant-bit set; key-up codes have it clear but are otherwise identical to key-down codes. ... Some other notes. Jeff Kaneko wrote that the operating system was "Unix-like". I don't know, I haven't seen it run much less try to hack on it, but from reading the manuals I'd say it was more p-System like, except that it runs 68000 code instead of p-Machine code. The hard disk(s) could be hooked up over the Omninet (in which case the disk box was connected to an Omninet-attached disk server box) or via a hard-disk interface that sat in one of the Concept's expansion slots. There were also expansion cards to control 8" and 5.25" diskette drives. I'm not sure exactly how the VCR-backup stuff works. From reading another manual (the Disk Drive Installation Guide) it looks like there is an option for the disk to have a "Mirror" built-in. There are four DIP switches on the back that need to be set different ways for different circumstances: no Mirror built in => all closed Mirror built in, NTSC VCR => all open Mirror built in, PAL/SECAM VCR => 1 closed, 2-4 open ... Well, I hope that helps a bit. Yes, I have one of these. No, I haven't done anything with it as yet, save haul the CPU, monitor, and keyboard up to VCF for folks to gawk at. -Frank McConnell

BBS Box

Well, I really want to just have about 5 connections. I don't want to be using the machine for my own purposes, but rather to "join in" on the BBS itself. I think that a 4800 connection would be good... about twice as fast as a 28800 internet connection. I'm really ready to learn, but at this time of writing, I only have the 486/66, and an 080880/8Mhz, which dosn't work. I really just want to make something for my friends and I to meet on... here, Internet is still expensive, and most people refust to upgrade to anything past Netscape 2.0.

I've already got two modems, one a 2400 sendf/9600 recieve, and another a 33.6 both ways.

How many multiple connections? What kind of speed per connection? Do you also want to use the machine for yourself at the same time?

Under OS-9, you may even have enough CPU over to play Rogue (tho not quickly). With a 6309 processor and NitrOS-9, you could most easily do this setup and still use the machine for yourself. (And yes, someone *has* designed an overclocking circuit to run a 6x09 at 4Mhz, except during memory accesses which does gain you a fair amount of speed... ;-) In the IBM world, I'd say for 4 dial up lines at 9600/14.4 you'd need a minimum of a 386DX 25 w/8 Megs RAM, running Dos/Linux (Windows not spoken here... too much overhead) and decent BBS software and you'd have no problem whatsoever.

It's the large kind, like they had back in the early 80's. An ST-251-1 isn't an IDE. It's a 40MB half-height 5.25 MFM drive. It'll run at 1 to 1 (also known as "no") interleave if you can find a fast enough controller; try an Everex EV-332 with fairly late ROMs.

The _encoding_ is MFM. Plenty of 5 1/4" form factor drives (such as the ST-238) used RLL encoding, but the same physical interface...i.e. ST-506/412. You can tell an IDE because it has one 40-pin cable...the ST-506/412 interface required 2 cables...a 20-pin and a 34 pin. ESDI's (rare) took 2 cables (20 & 34) also. manney(a)nwohio.com

'Naked Mini' docs needed

by jimw＠agora.rdrop.com

Just picked up a Computer Automation "Naked Mini" computer (PC board actually), and now need to find some docs on it. I can make a few assumptions based on examining the board, but there a number of option jumpers, connectors, and card edge (finger) connectors on it, and I'd just as rather not blow the poor thing up by experimenting on it. So, does anyone have either a spare copy of the docs, or can be convinced to run a set thru your favourite mode of duplication? -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw Computer Garage Fax - (503) 646-0174

new addition: atari portfolio

by sinasohn＠crl.com

> while searching around town for a mac II video card, i came across this > little machine for $10 at a computer parts store! not long ago, some idiot That's a great price for a portfolio. (Even without all the the expansion stuff.) The portfolio was one of the first handheld computers, and is (afaik) either the first or second handheld PC Compatible. (The other contender is the Poquet PC -- I've never seen a definitive answer as to which was first.) If you want to get rid of it, I'd gladly double your money! 8^) --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad sinasohn(a)ricochet.net that none but madmen know."

A: You were real lucky to get one for $10. B: re "idiot," I bought a Pofo with a cool leather case, two RAM cards and full docs from a Stanford student for $75, two years ago, and recognized it then as a bargain. Today in the Valley a working Portfolio, with case and set of goodies, is $150 to $200. (For most of its life the bare machine sold for $295 new.) __________________________________________ Kip Crosby engine(a)chac.org http://www.chac.org/index.html Computer History Association of California

Fido is far from dead!

by photze＠batelco.com.bh

Okay, let's all try to search for this Tim Jennings and try to encourage him to either re-connect or make a new version of Fido. There are enough of us with enough experiance to encourage him. Imagine! Having a living legend with us!!! I believe that BBSs in a HTML or Java-ized form still have a chance yet. They're 1. fast 2. cheap 3. You can use them for a multitude of services-like you could have 1 server, give it a cheap (sort of) 56K or ISDN connection, and then all users would have internet access. At least we could try to get patent rights if he'd let us. (Which he probably would, as he's not doing to much with it now!), and establish ourselves as a hisoric society (What else could you call us?), and make a few BBSs just to be a part of history. Oh, yeah, I have one more question. If I want to make a BBS (regardless or software), what type of hardware should I have to handle multiple connections? I believe that my computer is BBS-server-sufficent for DOS (2 GB HDD, 28 MB RAM, 486/66 processor), as that's twice as fast as a server would be in 1990, with DOS at it's peak, before Windows started ruining the whole thing :-) .

Outside N.A. AFAIK , it's going strong. Perhaps Bruce Lane could set me straight on this if you will. ciao larry lwalkerN0spaM(a)interlog.com

UK Based CPM machine collectors...

by kevan＠heydon.org

Hi, Are there any collectors in the UK that specialize in CPM machines. Last night I acquired a Philips PC2000 portable (along with the Corvis Concept) and while it is a nice machine (and has lots of documentation including service manuals) I don't have a great affinity to CPM machines because I have never used them out side of collecting them. (and I am trying to limit my collection to home micros, workstations and strange one off machines.) If you would be interested in this machine, and maybe some others I have then email me. -- Kevan Old Computer Collector: http://staff.motiv.co.uk/~kevan/
