Hi Sellam, I have an Amiga 500 with a Commodore 1084 monitor. The cable I use is a DB-25 to DIN-6 (5 pins around the outside, one in the center) - this does give me color. IIRC, the RGB output on the A500 is the rightmost DB25 connector when viewed from the back, however, I'm pretty sure it's marked RGB or something like that. The Atari ST's use a honkin big circular connector - I recall it's something like 13 pins (3 rows of 4 plus 1) - Best thing for the Atari is to use an Atari SC124 (mono) or SC1224 (color) monitor. If you don't have one available, you can build an adapter for a mono display on most PC SVGA monitors (I build one before I found the monitors, and it does work). Some of my ST's have RCA connectors for RF out, which you can display on a TV (not nearly as nice).

SCSI cable

by fire＠dls.net

VaX enthusiasts, I finally managed to get QBus SCSI card for my MicroVax II thanks to Ebay. It appears like it will fit in fine. It says KZQSA M5976-SA on the side. It has two Centronix-50 Female connectors on it. Question is what is easiest way to connect this to internal full-height DEC SCSI drive with standard 50-pin connector. Get a f-f gender connector and a cable with Centronix-50 F connector on one end and ribbon with internal connectors along it, and terminator at end? I cannot recall what model DEC drive this is, but I thought it was 4GB. How do I find DEC Drive model? I see numbers 74046725-0 A01 GM on side rail, 70-2988501 on top of drive, Model DSP5400S Rev RH12E-CY A01 on back of rail, and another label on the back of drive reading KB34426075 R-75. Board says 54-21265-06 A05 and ZG40516250 and 74P6 and Side 2 5021264-06 A01 I used to like programming in C and Fortran on this machine and the drive died a few years ago. I was hoping to load VMS on to the new big disk and have lots of space to play around in. Thanks for your assistance, Bradley Slavik

HP logic analyser questions

by philpem＠dsl.pipex.com

Hi all, Does anyone here own or use a HP 1650B (or 1651B) logic analyser? Do they need DSDD 3.5" disks or can they accept DSHDs as well? I ask because someone has just offered me a HP 1650B - system disk, a few pods and a 1650B analyser - but doesn't have any manuals or know what type of disk it needs. I'm guessing DSDD-only, given that the system disk is supposedly DSDD. Is it possible to duplicate the operating system boot disk using standard hardware (i.e. a PC or my RISC PC)? Anyone got PDF versions of the Operator's Manual, Service Manual and/or Programming Manual? Sorry for the OT-ness of this message - sure, it's not a computer, but it meets the 10-year-rule - the power-on selftest screen displays "COPYRIGHT 1987", so that would make the firmware, what, 16 years old? Thanks. -- Phil. | Acorn Risc PC600 Mk3, SA202, 64MB, 6GB, philpem(a)dsl.pipex.com | ViewFinder, 10BaseT Ethernet, 2-slice, http://www.philpem.dsl.pipex.com/ | 48xCD, ARCINv6c IDE, SCSI ...

Stupid Amiga Tricks

by vcf＠siconic.com

Why does everything have to be so difficult? I'm trying to set up an Amiga 500 for tonight's Computer History Museum event. It's got a DB-23 RGB output and a Mono out. I've got an Amiga 1080 high resolution color monitor. It's got a Video and Chroma input, plus a DA-9 RGB input. I've got an Amiga RF Modulator that plugs into the DB-23 on the back of the Amiga and has a composite Video and Audio out (and an RF out). Then I have several video cables. One is a DB-25 to a DIN. Another is a DIN to three RCA leads. And then there's the DIN to DA-9. At least one of these might be for the Atari 520ST (which I also need to set up). None of this connects up in a way which gives me colour on the display. Is it too much to ask to have products designed by people who are not insane? -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

None of the All In One macs supported NuBus (at least not directly, I believe I read somewhere that the SE/30 could use the IIsi adaptor card, but even if it could, you woudn't be able to close the case with it installed).

floppy low level format question

by dwight.elvey＠amd.com

Hi Jules The formats for MFM and FM are mostly well defined but they are not the only formats out there. There was a problem with one of the early controller chips ( I think it was the 1791 ) that had problems with all 0 gaps or something. In general, FM is FM and MFM is MFM. The clock rates are different for 8 inch and 5-1/4, single, double and quad. There are at least two other common soft sectored formats that I know of. There is the Aplle II format and there is M2FM that Intel used. Hard sectored formats used all kinds of encoding. Most use a simple return to zero type clocking. Sector headers had any number of different combinations. Anyway, going directly into the port is always going to be tough for a PC. PC's are busy with a number of things and don't make particularly good "real time" processors. I'd been thinking of the same things you've been thinking of. There is another way. A while back there was some modem boards called "softmodems". These were made by Cardinal and DSI ( later bought by that sound board company? ). These have DSP chips that run quite fast enough to bit-bang the data from a floppy. One can load code into these boards and run fast enough to monitor the data stream of a floppy. I've hacked the ones used by Cardinal and DSI to use for some DSP projects. I've been considering doing the same to capture images of disk. I'd though it would be easiest to use the disk controller in the PC to deal with select, track stepping and head loads while using this board to read the data. Once the timing data is captured, one can store or decode at ones leisure.

Prerelease Mac Portable?

by cb＠mythtech.net

I noticed this on ebay tonight: <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=4610&item=510057941 2> Seller thinks it may be a prerelease model because the FCC sticker says it isn't approved and can't be sold. Possibly they are correct, maybe it was a review model sent out before they hit the stores. I'd love to have it, opening bid of $9.99, but I'm sure it will go above my price range before it closes (and now that I've pointed it out here, that's almost a sure event). -chris <http://www.mythtech.net>

With regard to being able to FORMAT > a drive with an RQDXn controller, normally special XXDP programs > from DEC are REQUIRED! The RQDX1 and RQDX2 do tricks at startup to try to figure out what kind of drive they have connected (things like selecting unusual head numbers, seeking to high-numbered tracks) and if the results aren't what they expect, they won't recognise the drive. You can use many non-DEC 10MB drives with an RQDX1, given a suitable (early) version of the ROMs, but other sizes are tricky (and a drive that works with one version won't necessarily work with another). All the relevant drive parameters are fixed in the RQDX1/2 firmware. Things are much easier with the RQDX3, as it stores the drive parameters on the drive, so if you can once format it, it works. The table of values for approved drives is in the formatter program. In the later versions of the RQDX3 firmware, there is the capability to accept a new table entry from the formatter, and later versions of the XXDP formatter (ZRQCG0 and later) allow you to feed it values. If you do that, you also have to tell the formatter NOT to read the defect list (because there isn't one on a non-DEC drive, and when it tries to read it near the end of the 15-30 minute format operation, it will fall over). Working out the right values, however, is non-trivial. I've done it twice. The first time, in about 1990, it took days to work out what some of the entries meant. Now I just use drives it knows about already. You can also format a drive on an RQDX3 on a Vaxstation with VS2000 diagnostics. I don't know if that lets you bypass the UIT (Unit Identifier Table) as well, but I expect so. -- Pete Peter Turnbull Network Manager University of York

Blame it on the environment :) That wasn't the case for the one near me (pay to dump garbage... in NJ? BAH! We love toxic waste, we like to build sports stadiums on it). The one that had been near me told me they wouldn't take them, because they got sick of people expecting support, or wanting to return them when Windows crashed. Since they had a strick "All Sales As Is, All Sales Final" policy, they were simply tired of pointing that out to people. So they stopped selling CPUs to avoid the headaches. -chris <http://www.mythtech.net>

Only the third version is -YA, which supports RD52. The first version has problems with RX50s. V.7.0 23-238E4 and 23-239E4 V.8.0 23-264E4 and 23-265E4 V.9.0 23-042E5 and 23-043E5 M8639-YB is not RQDX3, it's RQDX2. There were three versions of the ROMs for this, and only the last two supported RD53. The difference between M8639[-YA] and M8639-YB is a diode and some hackery in the top left corner; this too could be done in the field so don't rely on the handle number. The purpose was to eliminate the "must be last card in backplane" problem. V.9.4 23-172E5 and 23-173E5 V.10D 23-178E5 and 23-179E5 V.10E 23-188E5 and 23-189E5 The RQDX3 also had several versions of its "microcode", and the first doesn't directly support RD3x (it has other problems too). The first three or four have problems with anything bigger than an RD53. ??? 23-166E5 and 23-167E5 V.1.10 23-216E5 and 23-217E5 V.2.? 23-243E5 and 23-244E5 V.3.? 23-285E5 and 23-286E5 V.4 23-339E5 and 23-340E5 (RQDX3-F002 / EQ-01532-02) I'm not sure if the 23-166E5 and 23-167E5 really exist; I have every version of the RQDX3 ROMs except those, and the numbers may be a typographic error (as implied in one of the FCOs). Or else they were so bad they were replaced before or very quickly after the RQDX3 release. I also have the RQDX1/2 ROMs versions 7, 8, 9.0, 9.4, 10E, but not 10D. -- Pete Peter Turnbull Network Manager University of York

Apple LaserWriter questions

by msokolov＠ivan.Harhan.ORG

As an alternative to DEC LPS, one other possibility I'm considering for a perfect PostScript printer would be an original Apple LaserWriter. But since I'm NULL in apples, I need some help. 1. Are all LaserWriters 100% pure PostScript printers, speaking nothing but PS? I know the very original one was, but I'm not sure about whatever happened later and whatever they make now. 2. Were there any LaserWriters made with duplex printing capability? If so, what's the earliest duplex LaserWriter? 3. The original LaserWriter had a serial port. But given the assault on serial ports coming from all directions, I don't expect the current ones to have one, or do they? When was the last LaserWriter made with a serial port? Was there ever a LaserWriter new enough to support duplex printing but old enough to have a serial port? 4. Are LaserWriter serial ports standard EIA-232 DB25 or something Apple proprietary? If the latter, what kind of adapter would I need to make? MS

Looking for Pittman's Tiny Basic

by bob＠applegate.org

Tom offered to send me a paper tape if I could read it. I asked on this list and got a lot of offers to help... thanks to everyone who wanted to help! Today I got email from Tom again. He moved several years ago, and just went to look for the tapes. The box labeled TINY BASIC had paper tapes, but not for Tiny. He's optimistic that he might still have the original tapes somewhere and he plans on looking for them. The only version he found so far has been for the 1802. In the mean time, if anyone on the list has any version of Tom's TB, he might appreciate getting copies, even if it's just the binaries. I'm desperately seeking the 6502 version, so hopefully someone can get a copy to Tom. He must have sold quite a few copies, considering they were originally $5 each ($5 for software? Amazing!). Hopefully someone has some old copies laying around. Bob

HP serial card

by pete＠dunnington.u-net.com

I've been tidying up (ahem) the workshop and came across a board I'll surely never use. It's some sort of Hewlett Packard serial card, about 8.5" long and 4.8" wide, with a 50-way edge conector at one end and a brown-painted panel, labelled "RS-232-C", over a DB25S, on the other. Part number 02670-60068. I've no idea what it's off, and no way to test it; yours for the price of postage if you can use it. -- Pete Peter Turnbull Network Manager University of York

I don't know about getting past the copy protection, but there is at least one fairly vast archive of Apple II software available online. I never remember the exact address, but it is something with asimov.net (the A2 newsgroups usually make mention of it from time to time) Your friend can always check there to see if the software he needs to transfer has already been made into a disk image that he may be able to use with the emulator. -chris <http://www.mythtech.net>

Cheetah Cub memory board For Sale or Trade

by doc＠mdrconsult.com

:-) Seriously, I have no use for the board and it looks to be in excellent shape. There's no point in letting it languish in a box for several more years. Specs again: ISA bus memory board Cheetah Int'l. Inc. "Cheetah Cub 2Mbyte Fast Memory" 4 banks of 18 256Kx1 socketed chips There is a set of DIP switches per bank, but there is no labeling and I have no docs. I've also never tested it and have no way to do so. For sale - Steve Thatcher says the memory chips are worth $0.75/each, and the baseboard probably sold for hundreds of dollars, so I figure $200USD. When you finish laughing, make me an offer. ;) For trade - GVP SIMM32 1MB or 4MB modules or 1Mx1 DRAM chips, or other ger for an Amiga 2000. If you have trade beads that are worth more than the Cheetah board, let me know. I'm not allergic to letting go some cash. Doc

The Lear Siegler ADM3 story concludes.....

by d_cymbal＠hotmail.com

They were there.......they weren't there.......they were there. After removing a rather large dumpster's volume of *stuff* (literally - should give you an idea of why we couldn't find them in the first place) from my father's storage shed we uncovered some of the little pale blue friends hiding in a back corner after all. There were not as many as we had originally thought (only 4) but they were there. 1 is already sold, 1 has a screen issue and I still need to test out the other 2. Anyway if you are local to Methuen MA and are interested let me know. I would prefer not to have to deal with shipping hassles unless I can't move them locally. I am thinking $10 for the unit with the screen prob and assuming the other 2 test out ok, $25 each for those. I also have a bunch of Visual Technology model 55 and 310 terminals if those are of any interest to anyone. Thanks for humoring me throughout this ordeal.

LF: Cromemco System3 boot floppy & HD info.

by dave04a＠dunfield.com

Mike K. and I are working on resurrecting a Cromemco System 3 This is a large S-100 rack-mount unit with dual 8" floppy drives and internal hard drive. Got it powered up yesterday, and all DC supplies appear normal. Managed to get it working to the point where it tries to boot from the A drive (floppy) - unfortunately we have no boot diskette. We able to get into the 'RDOS' ROM monitor for which we have no documentsion. Discovered the 'BA-BD' commands which try and boot: BA accesses the first 8" floppy, BB accesses the second 8" floppy. BC&BD just "hang". Also discovered an 'I' command (IPL?) which also hangs... We were not able to get any action from the hard drive - I don't know if it would be booted by 'BC', 'BD' or 'I' (or something else). I did note that the HD power was disconnected when we opened the box, so I do not know if the hard drive even works. Q1) Does anyone out there have a boot diskette for a Cromemco System 3? I'm pretty sure that if we had a boot diskette we could bring the system up. Q2) Can anyone tell be exactly what needs to be done to boot the hard drive? Are there any diagnostic procedures that we can use to confirm that the HD is operating? Any information or pointers to information on this system would be very much appreciated.

It is probably an EXPANDED memory card unless it has two bus connectors then it might be EXTENDED memory (didn't we just have a conversation about PC memory...) Ehh? 256K? So either the board provides 16MB of RAM, and the 2Mbyte silkscreen is just the shipped configuration, or somebody was wasting 87% of their money? BTW, the 10ns was a brain fart. I dunno much about DRAM, but I can read the -6, -7, and -etc extensions... :) So, more relevant to me, is the board itself worth anything outside the DRAMs? I have a friend doing a 68000 SBC project who could use some, and I think some of the rest would look fabulous on my Amiga 2000's A2091 board. One note - It looks like the DIP switches can be set per bank, but without docs, I'm guessing that taking any of the RAM off will render it inoperable. > It is more than likely one of the two memory standards and will work in any OLD PC.

Help to ID Unibus board

by squidster＠techie.com

Hello list, I've recently acquired a PDP-11/04 which in its past life was the controller of a CNC precision drill/router (not the network kind) system. Inside which have 2 boards (Unibus of course) described as below: First clue: Upper left hand corner says it's from "Advanced Controls Corp.". A quick search points to http://www.acsmotion.com as they seem to be in the same field, industrial/machine controls. Alas, their tech support doesn't even have a clue as to what a Unibus is... Both boards appear to be the same model/type, but one is a earlier revision with a lot of reworks; i.e. jumpers and 2 smaller daughterboards, of which the later revision board doesn't have. Each board have 2 BERG-like male connectors (50-pin and 40-pin) which (guessing here) connects to the actual drill/router itself. The board is made out of SSI/MSI/LSI TTL ICs. The most complex/prominent are the two 12bit Analog Devices DACs from the DAC80 variety, both made in the late 80s: DAC #1 - ADDAC80N (24-pin) - CBI-V - 8802 DAC #2 - ADDAC80D (24-pin) - CBI-V - 8811 I guess these are for the X-Y positioning, but of course I may be WAY out here.. Board #1 - S/N 11926 (sticker) - P/N 18992-103R (scribbled on handle) On the upper left hand corner: - Advanced Controls Corp. - PCB Detail No. 17795 Rev. H - ASSY No. 18992 Rev. - Replaces 17750 Board #2 - S/N 0000005077 (sticker) - P/N 18992-102R (scribbled on handle) On the upper left hand corner: - Advanced Controls Corp. - PCB Detail No. 17795 Rev. D - ASSY No. 17750 Rev. If anybody can positive ID these boards, it'd be great! If anybody has the programming docs for these, it'll be even greater! :-) /wai-sun p.s. These boards seems to have last tested OK on Oct 28, 2002 (from a "tested" sticker)! -- ___________________________________________________________ Sign-up for Ads Free at Mail.com http://promo.mail.com/adsfreejump.htm

Cheetah Cub board

by melamy＠earthlink.net

the little guys are only 256K by 1, so it takes 9 of them to make a 256K byte bank. PC memory has always been spoken off by the byte. As for the Amiga, it will take 8 (or 9) to make each 256K byte upgrade. Of course, getting nit picky, 256K bytes could be thought of as a 2meg bit upgrade - it sounds impressive and it what a saleman would have said...

I thought you meant 256K per chip, or 4MB per bank (16 * 256K plus 2 * 256K for parity). So are these 256K per bank, or 256K per chip? IOW, if they turn out to be compatible and I install 16 of them on the Amiga A2091, will that be a 2MB or 0.25MB upgrade? I'm a complete retard at memory components.
