Micropolis 1203-I disk drives available

by John.Honniball＠uwe.ac.uk

I also found two Micropolis 1203-I disk drives in the loft. They are 8-inch hard disks, +24V, -12V and +5V power requirements and connected to an ICL "formatter" dated 1989. The formatter has various chips from the 8X300 bit-slice system all over it. They're in Bristol, UK, if anyone wants them. -- John Honniball Email: John.Honniball(a)uwe.ac.uk University of the West of England

VAX power supply H7100B available

by John.Honniball＠uwe.ac.uk

I finally dug out the VAX PSU that's been in my loft for a while. It's a 5Volt, 100Amp power supply dated 21st Feb 1980. Model H7100B, with 240V 6A 50/60Hz input. No idea what model VAX it's for, but it was most likely a big 'un. The PSU is in Bristol, UK. It's very heavy, and 240V, so it's probably only useful to someone in this country. Anybody want it? -- John Honniball Email: John.Honniball(a)uwe.ac.uk University of the West of England

TI-99/4A

by CordaAJ＠nswc.navy.mil

I always thought the TMS9900 was a neat chip (having a PDP-10 background may have influenced me :-) Having the register set show up in memory gave me a nice warm nostalgic feeling. I wouldn't blame the poor performance of the 99/4A on the CPU. The architecture had a lot of nifty things in it. Most of the blame for the poor performance of the 99/4A falls on the low-end save-every-penny-you-can design criteria for the machine. I ordered the technical manual on the 99/4A from TI... What I saw in the manual made me gag... aside from a very small amount of memory actually on the system bus, any add-on RAM was accessed _serially_ (i.e. 1 bit at a time) via what TI called a "CRU" interface (basically a high speed serial port) I believe we can all appreciate the crippling effect on any machine's performance when the bulk of it's memory is only available through a 1-bit serial interface. BTW, I also had the technico board... a really neat product that never quite took off. :-( > -----Original Message----- > From: ajp166 [mailto:ajp166@bellatlantic.net] > Sent: Tuesday, January 30, 2001 8:30 AM > To: classiccmp(a)classiccmp.org > Subject: Re: TI-99/4A > > > From: Ross Archer <archer(a)topnow.com> > > > >Correct me if I'm wrong, but I've heard the 99/4A suffered > something of > >an unfair rap for being slow due to the fact that its TI BASIC was > >dreadfully inefficient and sloppy, and that little or no > blame for its > >slowness rested on the actual CPU or hardware.

Beetle-Net

by mmcfadden＠cmh.edu

Manual transfer of data was the only way to go in the "old days". There was bike-net also. I used to take my 800 bpi tapes over to the computer room and knock on the back door, they would sneak them in. The official way was they logged in tapes twice a day, slow turn around. There was a slight risk of bike accident especially if I was not looking, perhaps distracted by scenery :) The risk with Beetle-Net was that if you left the top down some wacko would walk off with your tape. One of my fellow students came back to his car to find the tape unspooled down the hill, somebody stood on one end and rolled the reel down the hill. We tried manually re-rolling the tape and decided there was to much dirt and grime on it. Later in the 80's I held the local record for awhile, I carried 10 LMSI 12" 2GB optical disks from one end of the hospital to the other, they had planned on doing a network transfer via ftp. The sneaker was faster. 20GB/10 minutes = 2 GB/minute in 1985. Mike mmcfadden(a)cmh.edu

(Windoze >users may spot a parallel here.) >;) Partially correct. there were many issues. One the 9900 is 16bit wide data bus demuxed to 8bit (costs a lot of cycles!, penalty 1), it's run at less than maximum speed for the time and BASIC {internal} was interpreted as an end language {penalty 2} and the BASIC interpreter was interpreted {penalty 3}. Those things really hurt speed. The other side was it did have one of the better from a capability standpoint Basics in the standard console. >The TMS 9900 CPU actually used a "window" in RAM as its register space, >with an internal pointer register to locate its base address. This was >actually a great idea at the time, because CPU cycles were long enough >back then it made no difference whether you stored temporary values in >internal registers or external RAM, as either could get you your data in >the 1 cycle time available. Actually many of the older DEC hardware also used part fo ram to implement the registers including early PDP11, DEC-10s and previous machines. The idea was not new and was to save logic in the CPU as FlipFlops (memory) were costly in hardware back then and even in late 70s were costly on silicon. The other factor is the 9900 was a single chip recreation of the TI990 mini (not unlike like the 6100{pdp-8}, LSI-11 and DG MicroNova). >(And interrupt latency can be really short if you can make a "fresh" >register bank with one register load!) The ability to context switch fast was one of the strong points. Compared to Z80 or 8086 it was a nicer cpu to program save for the 32KW memory limitation. In many respects it was more similar to the minis like PDP-11 or Nova than the micros of the time. It was rich in general registers, Addressing modes and IO. I have a Technico Super starter board and it runs the TI9900 at 4mhz with 16bit wide memeory and rom really fast compared to the Z80 (comparison made on both machines I still have from 1979!). I picked up the TI99/4a and was sadly disappointed save for the bundle of really good and inexpensive software for it. Still, it plays a mean game of Parsec!!! Allison

I still have 4 of them. HAving hacked one rather severely the CRU interface was IO only. Ram was either accessed as: 128 words on the 16bit bus (pair of 6810s) this was fast ram relative to all other. 32KW in the Expansion box, this was slower due to the word to byte wide conversion logic (adds at least 2 waits for every access!) Grom, byte parallel, sequential access, you wrote to a register in the GROM to set the starting address and every byte read would increment an internal counter. This was slow at times being both on the byte wide bus and the higher software maintenance. Mostly used for internal Basic and the plug in carts. Vram.... 16k or 4116 Dram on the video refresh bus. This was also used as general storage for the internal BASIC and was a byte wide access via the 9918 VTAC and also CRU IO (setting a pointer). Horribly slow, cool graphics for the time! I have a severely hacked one with 32KW of 61256(32kx8) and 32KW of Eprom both 16bits wide and clocked to 4mhz... it screams. Nothing standard and doesnt run any of the TI stuff. Nice package though. The CRU interface for IO was actually pretty fast in practice and had flexibility that was not available on most of the 8bitters. >BTW, I also had the technico board... a really neat product that >never quite took off. :-( IT's interesting that it was one of the first 16bit cpus and was not well supported by TI at that time.

Sharp PC7000

by cfandt＠netsync.net

Hey folks, who's got one of the above subject machines? I found one over at the Salvation Army store. Looks very clean and complete: has the Operator's manual in a slipcase, MSDOS manual (DOS v.2.1), keyboard, printer, vinyl slipcover, cables, some floppies of s/w. They want $50 for it which is probably a little high. Maybe I can negotiate it down to something better. Found several hits on a NorthernLight search. One good photo to help show what I'm talking about is at: http://home.plex.nl/~hwrsoft/11.htm Some list members' collections show as hits too, but no descriptive info was to be found in those links. Anybody have any comments about this machine? How was the screen clarity?

Does anyone have any ideas? Jeff, I've got a very similar setup. NeXT '040 cube, NS3.3 w/Y2k patches, crossover ethernet cable to a Mac Powerbook 3400 running MacOS 8.1. The NeXT will respond the Mac *if* the Mac is already connected and running when the NeXT boots. Of course the Mac has to be set up for TCP/IP to the ethernet port, etc. I usually hit the NeXT with Fetch 3.0.3 from the Mac first, but I have also succeeded by firing up CAPer on the NeXT first then looking in Chooser..Appleshare on the Mac. The NeXT setup is the same as it was in my office, on an ethernet internet hookup, so it's possible there are some settings in there not the same as yours. For example, during the NeXT boot process, I get some message about "not being able to find a server ... hit c to continue or see my administrator" (or similar) and have to hit c to continue. If that's the problem, email me direct and I'll post the NeXT Networking setup. http://www.peak.org/next/apps/internet/www/OmniWeb/ for a more recent version?

Some time ago, a seller on eBay mentioned in the item listing for some IIfx SIMMs that they also work with Amiga accelerator cards made by GVP (Great Valley Products). Has anyone tried using IIfx SIMMs with a GVP card? (One which takes 64-pin SIMMs, obviously.) While the connector may be the same, I'm sceptical that they are compatible; a few years ago I tried an AST 64-pin SIMM in my GVP card unsuccessfully. -- Mark

Hardware Emulation (was Re: Spectrums, Ultrix, feeling old :)

by cmcmanis＠mcmanis.com

One of the 'toys' I recently purchased is an eval board with the Xilinx Spartan II 200K gate FPGA on it. My plans for this are classic computer emulation. (there is already a PDP-8 VHDL description floating around and I'm looking at doing one for the PDP-5, PDP-11, and PDP-12). But this board includes bits that let you drive a VGA display with it if you choose and it has PS/2 ports etc that you can also use. So I figured wouldn't it be cool to actually try doing "new" Atari 2600 hardware or something like that? It should be pretty easy to design a PONG equivalent game, the original was all TTL gates anyway. All I need it another hobby I don't have time for but it helps motivate me to learn the tools if I've got a project to work on. --Chuck

Please help identify S-100 boards

Hello all, I just obtained three S-100 boards that I thought were floppy controllers, but on inspection, may be something altogether different. I have no documentation on these boards, so here's the description: All three are marked "DYSAN (c) 1982" Two are marked "Wear Tester Cert. Bd." One is marked "Model V TrackWriter Certifier Sub." All three have 34-pin and 50-pin connectors, and all three look to be the same PCB layout, but with different components present or absent, and slightly different silkscreenings. For example, the two "Wear Tester" boards have ByteDAC chips in two sockets, but the "Model V" has those sockets empty. Most of the other chips on the boards are either standard "74" logic, or Op-Amps, or the aforementioned ByteDAC chips. All three also have a National LH0032CG in a can (don't know if that's significant or not). If anyone can identify these boards, or more importantly provide documentation (including schematics), I would surely appreciate it! I am willing to trade $$$ for information... Thanks! Rich B. P.S. I'm a digest subscriber, so I will not reply immediately if you send to the list....

Collecting and taxes

> Interesting question though -- "should the tax people visit my site they > might think I'm making a living from buying and selling machines" -- what > if the "site" in question is a web site? Can the revenooers use what they > see on a web site against the owner? :-) Web sites currently don't enjoy the protection they should. If you painted a picture of Superman on your bedroom wall, because you like Superman and want people who come to your bedroom to know you like Superman, that's fair use doctrine. If you put a picture of Superman on your web site, and DC Comics sees it, you'll get a cease-and-desist letter from DC lawyers. And if you don't comply, you're in court. That's because the law isn't making distinctions between corporate and personal/private web sites, but it should. My personal home page is a virtual bedroom wall. Enough of that, we're swinging way off topic again. -dq

As far as they're concerned you have about the > same rights that the Jews did in Nazi Germany! Actually, I have. In 1986, when I filed for Chapter 13, they sent me a letter saying I hadn't filed for 1985 and 1986 and owed an estimated $11,000 in back taxes. I wrote back saying, it was true, I hadn't filed for 1985, *yet*, but would do so now as I expected a refund. Additionally, I sent them photocopies of the 1986 filing & refund check they didn't seem to know about. And human engeineering has yet to create the lock that can keep me out of my house.

TI-99/4A

by ajp166＠bellatlantic.net

From: Cameron Kaiser <spectre(a)stockholm.ptloma.edu> >If the TI uses a DSUB-9 connector (I must be the only one here who doesn't >have one), I wonder if the Tomy Tutor joysticks would work. I know TT >joysticks are definitely not Atari compatible -- I nearly killed my C64 with >one (remember that the joystick lines go right into the PLA, the glass jaw >of the C64). Atari joysticks may work with the TI save for connector. The ti joystick is only an array of contacts in PARALLEL with the keyboard contacts and there is no logic inside. A common problem is the TI version of the joysticks have a poor contact life so bad ones are good for the plugs and wires. Allison

Making an Atari 400/800 Basic cartridge EPROM type

by mmcfadden＠cmh.edu

I seem to remember from the dark ages that the Atari cartridges could be made using a standard EPROM and ZIF socket and that there was an inverter on one leg of the EPROM. The guys that I knew who programmed EPROM's for missiles also made Atari cartridge copies. Somewhere I have a cigar box full of EPROM's of all of the common Atari 2600 games. I also have a piece of circuit board with a ZIF socket on it. Mike mmcfadden(a)cmh.edu

WTB: MicroAce, CTM magazines

by xds_sigma7＠hotmail.com

Sure, you could kludge something together, but I have no interest in doing so... Since I truly do intend to have a museum at some point, I wouldn't consider a kludged-together Terak to be something of museum quality.. Hell, if I just wanted it to work, I'd try to find out how standard the qbus backplane in it is, and from there you could perhaps make it into a normal 11/23, which would be useful since it has an 8" floppy. Thanks for the advice on the monitor and keyboard though, maybe it will help someone with different goals : ) Will J _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com

There is a long-established tradition here in America wherein we take great difference with a revenuer's (taxman's) attempt to enter the premises. The tradition involves guns and dead taxmen. All kidding aside, the 4th amendment to our Constitution elucidates our intrinsic right to be safe and secure in our persons and property >from unwarranted intrusion. In other words, a U.S. citizen is never required to admit a government agent unless the agent has a warrant, and while it may happen from time to time, I don't think that revenue agents typically ask for and receive warrants to enter a private residence. There are, however, some horror stories I could tell involving the U.S. Marshalls' Service who are able to perform warrantless searches, but they're looking for pirated software, not old iron.

DecStation Help please!

by linc.fessenden＠juno.com

I have a couple DEC Maxines (5000/33's) and I am desperately trying to install a virgin Ultrix 4.2 on them without any luck. Someone please help! I have the CD media for Ultrix 4.2 using a scsi drive that works to install on old Sparcstations so I am assuming it handles 512 sectoring. The cdrom drive works fine. The Ultrix 4.2 cd looks fine (an original). If you watch the boot messages on the machine it finds the cdrom drive on rz6, so.... I rebooted and at the prom, I try boot 3/rz6 and then boot 3/rz6/vmunix both without luck.. After each command the response is identical. The cdrom spins up for a minute and then stops. No further prompts, action, etc.. Anyone have any suggestions? -Linc

Datamaster and parts available

by rcini＠optonline.net

Hello, all: I know that I posted this once before, but I'll make the offer again. I have a partially-working Datamaster for sale or trade. It consists of the Datamaster unit, lots of spare parts (including power supply, keyboard, and miscellaneous boards) and a few disks. There are no manuals or other paperwork. There's only one condition: pick-up only in northeastern Nassau County, New York (Long Island). This is large and very heavy, so I'm not inclined to ship it. I also have a few random items available that are shippable: Two 3Com PCI network cards (spares), a Zilog Z8 ICE/evaluation board, and NuBus graphics card and TokenRing cards. Anyone interested, contact me off list. Thanks. Rich ClubWin!
