PCBs to build your own home brew CP/M computer

by LYNCHAJ＠YAHOO.COM

Hi! There are plenty of PCBs still available for anyone who would like to build their own home brew computer. Building a home brew computer is highly entertaining and a great way to teach about computer fundamentals, electronics, digital logic, etc. http://n8vem-sbc.pbworks.com/w/page/35044530/PCB%20Inventory These are available from myself and others on the N8VEM mailing list. Feel free to sign up and ask questions. http://groups.google.com/group/n8vem http://n8vem-sbc.pbworks.com Thanks and have a nice day! Andrew Lynch PS, all you need is the SBC V2 to start and it will boot to CP/M 2.2 from ROM with a RAM drive. Next builders add an ECB backplane, a DiskIO V3 for storage, and ColorVDU for display but those are optional.

SCSI preprocessor for HP16500

by alexandre.tabajara＠gmail.com

Howdy, people! I'm trying to help N8VEM project (and a local project) into making a SCSI emulator. I'd like to have a SCSI bus preprocessor on my HP16500C to help. Maybe someone has a spare stashed somewhere and wants to sell by a nice price? :o) Ok, it is not easy to find, but what is the problem in asking? ;o) Thanks a lot, Alexandre Souza --- Enviado do meu Motorola PT550 Meu site: http://www.tabalabs.com.br

This is total sacrilege to an old calculator enthusiast such as myself. It hurts to see a machine like this gutted out and sold as a trinket.

TEAC FD-55B jumper setting for Kaypro?

by brain＠jbrain.com

Thanks to Dave Dunfield, I now possess some TEAC FD-55B units for the Kaypros. I popped one in and it booted CP/M fine. Formatted a disk fine. But, before I install them, I thought I should ensure the jumpers are correct for the drive. Reading the manual, I have a few questions: * Should IU (head load on pin 4) or HL (head load on pin 4) be enabled? * Any reason to leave ML (motor running) on and have the motor run all the time? * What combination of IU/U0/U1/UR should I use? I tried IU+U0 thinking the light would be on only when the drive is running, but that's not true. * HS + MS or HM + MS? Neither seems to make any difference on the Kaypro * teac notes it ships the 55B with HS,DS0,IU,SM,and PM. I have DS0 (or DS1), HM, SM, and PM. The unit had ML strapped, but I removed it.

Really? If I find a rusty old calculator I don't feel any _responsibility_ whatsoever. Although I'm sure there are people on here who would pass a law if they could, along with laws _forcing_ programmers to use obsolete hardware, users to pass an exam, and in general do and think 'the right way', I think I still have a choice about what to do with it, if anything; I will concede though that posting a video on Utube of my using it for target practice would be in bad taste. Like I said, I happen to have an almost identical board out of a calculator that was not repairable (IMO, which is the only opinion that counts IMO) and I've had no qualms about removing a few Nixies for use elsewhere; I was thinking of offering it to Rick or Brent for parts but since that just earns insults and condemnation instead of appreciation I think I'll just hang on to it and maybe make the core into a piece of 'art'...(hmm... add some tiny LEDs, maybe two or three of the Nixies... an image is starting to form...) > You wouldn't scrap an antique car and attempt to sell just the floor mats > and seats just because of some body rust and a non-functional engine.

Sweden's postal service is a government-owned corporation, owned partly by the Swedish and partly by the Danish government. It is as far as I know not publicly funded, but required to pay dividends to the governments. It has gone downhill, but is still better than the other alternatives. Schenker (owned by Deutsche Bahn) is cheaper for parcels but IMO rather less good. Usually the Post Office works reasonably well, but just this week they appear to have lost a parcel from Germany which was one of those signed-for things, which arrived while I was away and supposed to have been sent to the local pick-up place. However they do not know where it is. Very annoying. If it is lost they will pay for it, but that takes time and I will have to order my stuff all over again. /Jonas

TU58 tape issues

by blstuart＠bellsouth.net

So I decided to write a TU58 emulator for my 6809 SBC to serve "tapes" >from an SD card. So far, I've only implemented a first version of the read side. It seems to work on an XXDP image I found online. However, when I try to boot an RT-11 tape image, I get: @1000G?BOOT-W-Error reading handler ?BOOT-W-Error reading handler ... ?BOOT-W-Error reading handler RT-11SJ V04.00A ?BOOT-W-Invalid or missing TT.SYS ?KMON-U-Overlay read error . .SHOW ?KMON-U-Overlay read error Any ideas on what might be causing this? I've dug up the old rtpip code and gotten it partially working in a more current environment, and it seems to be happy with the tape images I have. I've had this happen on two tape images. Also the original tapes from which these images were made are ones that I've booted from (after I made the tape images), albeit over 20 years ago. So it looks like either something strange in my tape images or something in my emulator that works to load the secondary boot, but fails for loading some other parts of the tape. BLS

Raised flooring

by useddec＠gmail.com

I came across about 50 pieces of raised flooring today without (yet) any of the other parts. The owner said to make an offer. It's been sitting outside, four stacks on a pallet. I told him I didn't want it myself but would try to find a home for it. I couldn't bend to look at it and no way was I going to try to pick one up. I'm sure there are several people here who know the weight. I'm not sure of his zip, but mine is 61853 and he is within 25 miles or so. Feel free to contact me off list if you are interested. Thanks, Paul

Review of Philipp Hachtmann's "Omnibus to USB!" board - Update

by lbickley＠bickleywest.com

I received my "Omnibus to USB" board for my PDP-8/E a while back, but a heavy work load prevented me from trying it out until the last couple of days. Review of the "Omnibus to USB" board by Philipp Hachtmann: ---------------------------------------------------------- What it is: A KL8E compatible board which runs at a "blinding" transfer speed. Currently, it's primary use is to dump and restore RK05 packs on a PDP-8/E/F/M to/from a PC. Speed: Transferring an entire RK05 pack to a PC takes less than 51 seconds. With verify it takes 1 minute and 40 seconds. Restoring a pack >from a PC image with or without verify to the RK05 takes the same amount of time as dumping. Will it work O.K. on a "loaded" system?: In short, the answer is "yes". Here's the configuration of my test PDP-8/E: (1) KK8-E CPU (1) KE8-E Extended arithmetic element (1) KM8-E Memory extension and timeshare (4) 8KW DEC Memory - total 32KW (1) RK05 Disk Drive (1) VC8/E X/Y -> VT01 (1) RX8-E Interface -> RX02 (1) MI8-EP Hardware bootstrap loader for RX01/RX02 (1) KL8E Async (1) DK8-EC Crystal Real Time Clock (1) Omnibus to USB This system is at the max in terms of current draw for the H724 power supply. How difficult is it to use? It's very easy to use. It comes pre-configured to use I/O addresses 40 and 41. (Switch changeable). All the software below is downloadable >from Philipp's website. To dump an RK05 pack here's the procedure: Load the SPEED8.RIM program into the PDP-8/E using the standard RIM loader. (Or use SPEED8.BIN via the standard OS/8 loader). Halt the system and set the switch register to 200. Clear/Load/Run On a PC running Linux, run "rktool" as follows: To dump an RK05 disk with verify: rktool -r -V filename To restore and RK05 disk with verify: rktool -w -V filename You can dump/restore as many packs as you like as long as you leave SPEED8 running in your 8/E/F/M. Is there anything to watch out for? 1) It's important to set your Linux USB port properly with the following: "stty -F /dev/ttyUSBx raw -echo" 2) [Change from previous email] There was a minor glitch in the original version of rktools. If you don't ask for a verify, you will get a large weird number of verify errors indicated at the completion of the read or write job. This is a false indication - the image is perfect. I found that a single variable was not initialized - so I updated "rktool" and now it works as expected. (I just sent the updated rktool to Philipp).

My solution is to always verify (-V). The board is so fast that there's no reason not to verify.

Obviously you're buying into a bad deal. ----- Reply: ----- Ah, thanks for the heads-up!

But now that I know that buying and selling parts from gutted old gear are 'crimes', I'll throw them in the landfill first thing tomorrow morning (after first using them for target practice of course). I certainly don't want you, Dave, N0body H0me, etc. to think that I suck; bad enough to be chastised by Dave for scrapping for parts some LA100s that I'd offered several times with no takers. m

identify this baud rate generator

Can anyone identify the equipment this board came from, or the company going from the style of part number? It's a baud rate generator, or presumably is, given the "TTY" on the solder side. ~ 10.7 MHz clock, 12-14 stage divider, late 1970's. http://www3.telus.net/~bhilpert/tmp/brg/ Seemingly odd choice of clock frequency for a baud rate generator, results in some error at the higher standard rates.

New scans have been posted at our document archive of the Interactive Computer Systems OmniFORTH manuals, as well as those for its predecessor, fig-FORTH: http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/InteractiveComput… http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/ForthInterestGroup Each time I do a scan, the original document is either stored, if I find it to be of value, given away, if someone else does, or recycled, if no one appears to mind. This one rides the edge of the first two categories, so if anyone would like the original, FFS, let me know. There is no content to be gained by having the original vs. the scan, yet someone may still want the tactile (and nasal!) experience of 33 year old paper. Shipping will be from the 60070 ZIP. -jht -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org

TRS-80 Model II in Portland Area

Hi Zane, I'd hate to see this go in the dumpster. If nothing else, there are parts inside (e.g., the Z80 and support chips, the Shugart 8" drive) that could be useful. If you don't get any takers, please let me know... - Earl On Sun, Jun 9, 2013 at 8:52 AM, Zane H.

S100, but not S100

by dgriffi＠cs.csubak.edu

I have some boards with gold fingers that match S100, but are obviously not. For one, they're dated to 1973 and from Intel. Also, they're two inches narrower and 1.5 inches taller than an S100 board. What are they? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting.

[cctalk] Old UNIX Systems

by seefriek＠gmail.com

We're doing NetBSD and 80386 again? Evil cabal responsible for crimes against computing again? Jason Thorpe and others were talking about fundamental problems continuing 80386 support, what, almost a decade ago (no...the 80386 is not simply an older 80486)? They announced the intention to drop support in 2007, and dropped it in 2009. It was not a secret and it wasn't a smug "buy bigger/faster/stronger" dictate; they still support VAX and a pack of ridiculously obscure mc68k boxes, after all. 80386 support died because no one stepped up to support it, even though proposals were made as to how to do that. Based on that, the core developers made a decision about how to allocate scarce resources, and in 4 years the world has somehow failed to end. If a single person had stepped forward to take on 80386 as a distinct port, it could still be in there. It not like ns32k or mc88k, where getting things going means recreating GCC support, figuring how to jump to ELF, etc. And yet, since 2009, no one has picked up 80386, which pretty much tells you how really important it is in the grand scheme of things.

SD: Under RT-11

by jhfinedp3k＠compsys.to

Does anyone else who is reading this still use the DEC SD: (Symbolic Debugger) under RT-11? I have been spending some time, of late, becoming more familiar with this software and I have noticed a few areas which could use some improvements. This post is in respect of version Y01.16 which runs under the most recent versions of RT-11, and in particular the SDHX.SYS variant which runs under a Mapped RT-11 Monitor. The two major aspects that could use some improvement are to reduce the Low Memory required from 1124 words to perhaps half that requirement. The second is a lack of a history capability. Doing so will certainly require the use of additional Extended Memory beyond the 8192 bytes already in use and that is probably the major obstacle to overcome. One other aspect that might possibly be changed is the fact that the SDHX.SYS variant freezes RT-11 when the user is at the DBG> prompt. While that is a major problem, I don't know if there is a solution which would allow the user to unfreeze the system and allow other jobs to execute. As for the Symbolic Debugger capabilities that are available under RSX-11, in particular with respect to programs with overlays which the DEC Symbolic Debugger under RSX-11 is reported to posses - even before the overlay is loaded, that may also be possible if there is sufficient need under RT-11. I would appreciate a response from anyone who still uses SD: under RT-11, especially under a Mapped RT-11 Monitor and most definitely from anyone who uses the version Y01.16 which DEC limits to certain versions of RT-11, but which is capable of supporting debugging under versions of RT-11 at least as far back as V05.03 of RT-11.

PDP-11 OS Guides/Texts (RT-11, RSX-11, RSTS)

by pbirkel＠gmail.com

As long as we're talking about teaching & books/course materials, let me pose the following query: Does anyone have any good references for learning/using RT-11, RSX-11, and RSTS (the principal PDP-11-based operating systems), beyond the various online DEC-docs? Absolutely not "for dummies" style books (were "for dummies" books yet been invented in the 70's?), but neither simply a regurgitation of a DEC reference-manual! Thank you, paul

DEC-Writer III LA120 played dead

by hachti＠hachti.de

Just for your amusement - and to help people who might once grep the list archives to find the solution if they're as stupid as me... I just carried a LA120 upstairs into my screenprinting/collection room. And I wanted to test it because it had stayed many months on a pallet under a cloth. After power on it just worked fine. And than the paper ran out. It made a lot of sound with blinking and all that. So far... But when I power-cycled it - it played dead. All LEDs on and all digits lit. I was kinda confused because the digits are processor controlled. So it could not be completely dead. But why didn't it complain and blink and just SAY something?!? Severe firmware corruption? All voltages were there. No fuse blown. Nothing disconnected. The manual helped me: If the cover is open or paper out on power-on, the LA120 will just play dead. Without any further complaints. Many of you out there might know that. But I can imagine that there are some potential future victims of this behaviour: You have been warend now :-) Kind regards Philipp

cctalk Digest, Vol 118, Issue 32

by pechter＠gmail.com

Anyone have archived CD's or ISOs of Debian Slink and Potato and Corel Linux releases and sources... I've got a pet project I want to start work on and I haven't been able to work up. I had Corel Linux running pretty well on an old Pentium Thinkpad with the modified KDE they included. I'd like to look at rebuilding most of it with updated software and security fixes, but I want to compare the Corel sources with the original Debian and slowly upgrade the sources to more secure versions (I had already done new ssh/ssl/glibc about five years ago). I guess I'll stop at the later 2.4.x kernel revs, since they were much better than the 2.2. Bill -- d|i|g|i|t|a|l had it THEN. Don't you wish you could still buy it now! pechter-at-gmail.com

This one is available on Amazon with **LOOK RARE** pricing, currently around $120. I paid a lot less for a copy a while back. It seems as though the sellers have an automated algorithm where if there is a low number of copies currently listed and one sells from any seller then the remaining copies at other sellers almost immediately get jacked up significantly in price.

UNIX for Old 486 Boxes

by mcquiggi＠sfu.ca

Hi Ethan: I'd suggest a 3.x version of FreeBSD. I recall from the day that a few megs of RAM will get you support for 10-20 simultaneous users. You can run all the usual servers and services. I used a 3.x box to teach an introductory UNIX class for a couple of years at a Vancouver-area technical college. I can make you an ISO if the FreeBSD site doesn't have 3.x still available. Kevin Message: 17 Date: Sat, 8 Jun 2013 01:38:58 -0400 From: Ethan Dicks <ethan.dicks at gmail.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: What versions of Linux (or UNIX) are good on old 486 boxes? Message-ID: <CAALmimn9vrAuMHiuXZyyv6TZ6sNKBEot0JLbg1LUE9GbDcmqFQ at mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 Hi, All, Going through stuff on the shelf and I've run across a couple of 486-based fully-integrated LCD/touchscreen machines. One is a SCAN Corporation SCANtouch Model 3000, the other is a Planar Systems box. Similarities include limited memory (2x 72-pin SIMM sockets on the SCANtouch or 4x 30-pin SIMM sockets on the Planar, both with "double-sided SIMM" support, so 64MB or 32MB max respectively), one ISA socket (no PCI), onboard NE2000, serial, parallel, 2.5" PATA disk... these systems will run MS-DOS, of course, and Win95 (the touch screen on the SCANtouch is old enough that it apparently doesn't work with Win98 mouse drivers, according to forum posts I dug up). I really don't care about running DOS or Win95 on a touchscreen/LCD machine, and the practical alternative is some flavor of Linux or UNIX. What I'm having difficulty digging up is when the break from low-mem/pre-Pentium systems happened and what distros are on which side of the divide. RedHat 7/8/9 require a Pentium and 64MB minimum >from what I can research/remember. The last time I ran Linux on a 486, it was Yggdrasil (and before that, some early form of Slackware on a 386). So... anyone have a "go-to" Linux distro for sticking on a 486? I know RedHat 5.2 will work - that's what's on my PS/2-E (w/486SLC and 12MB of free mem I was recently discussing). Any other choices? At one time, when a Dell P-133 Latitude laptop was my main machine, I ran Solaris 7 on it (because it was a better choice than Linux at the time) even though it still had some issues (and workarounds) with the NeoMagic video chipset and the 3Com 3C589 PCMCIA NIC. I suspect this is likely to have similar "challenges". I've dug up full specs on the Scantouch 3000 innards - PCM-4890 integrated CPU board, NE2000 (Realtek RTL8019) Ethernet, C&T 65545 video chipset w/800x600 max LCD resolution, Sharp LM10V33 VGA (640x480) 10.4" color LCD, VIA VT82C496G chipset, , PC104 sockets... so I have little concern about getting *something* working with it. Getting 10-year-old RedHat working on a Pentium-class machine isn't a real challenge, but it's been long enough since I've really fiddled with 486s that specific memories of system configuration are getting a bit fuzzy. At one time, over 15 years ago, it was a daily thing knowing the ins and outs of what the 486 could and couldn't do, before CPUs and memory and clock speeds took off like a rocket, and when 4MB was ordinary, but more than 16MB was uncomfortably expensive for hobby gear. Helpful suggestions wanted. Thanks, -ethan

Old UNIX Systems

by healyzh＠aracnet.com

I've been working on getting shelving installed in our Garage, and as a result, I've been digging back to some systems that have been buried. Right now I'm moving a bunch of Sun hardware and it hit me. What good are old UNIX systems? I'm curious, what are people using things like Sparc 2's through 20's for? Or even Ultra 60's and older? Part of the problem I'm looking at is that you can get something like a Raspberry Pi that will cost a fraction of what a Sun system costs to run. I won't ask this about my two SGI O2's, as they're artwork. BTW, I'll be honest, I'm actually using two Sparc 20's right now. Each one sits on top of two Record Crates, and acts as a speaker stand. They've filled that role for several years. Somehow though, furniture and artworks really aren't the uses I'm looking for. :-) Zane -- | Zane H.

Sirs, I'm looking for the "SCSI Bus & IDE Interface, protocols, Applications & Programming" book. Tried to buy it on amazon, and there are books from 0,01 (!!!) plus 3.99 shipping. Is there something a brazilian isn't used to, or this book used is SO cheap? Anyone has one around willing to sell for a fair price?

discontinuance of VMS

by mcguire＠neurotica.com

I am still looking for a "horse's mouth" reference, but it seems HP has just given the VMS community the finger. "Ric Lewis at HP sent out a letter basically saying VMS is dead. Support up through 2020, but 2016 is the last sale of VMS- supported hardware." Now, of course, "will only be sold for 2.5 more years and will only be supported for 6.5" doesn't exactly say "dead" to me; it says "WILL EVENTUALLY BE dead", but still, this does kinda suck. But it's awesome that it lasted this long. From 1978 until 2020 is a great run in this industry, one for the history books. And I'll be running it, God willing, well after that. (if I'm still breathing!) (Now we get to watch all the stupid suits who equate "no longer sold" with "doesn't work anymore". Heh.) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
