I've more of these than anyone will need and they're all brand new. 3 packs of Bernoulli 5.25 44meg disks KAO 5.25 88meg syquest disks. The label inside says they are formatted for Macs but includes software for wintel machines also. $1 each plus whatever for shipping and they're yours. Just say how many you want. -- I am not willing to give up my privacy for the false promise of 'security'

PDP-8 "Introduction to Programming"

by dave.symmes＠hp.com

I tripped across this email link on a Google search. I was the author of the original PDP-8 * "Introduction to Programming", published in either late 1968 or early 1969. I hired onto Digital straight out of college as a tech writer joining a department of four writers for the whole company. Almost 40 years later I am still with HP.

IBM 6094 Lighted Programmable Function Keypad - bulk buy on eBay

by listmailgoeshere＠gmail.com

Hi cctalkers, The 6094 LPFK has been discussed on this list before (see thread "IBM 6094-020 Lighted Program Function Keys"). I notice that there's a bulk lot of 19 of them on ePay (see 180215874744) - now, I don't want 19, but I'd like one. I'm sure there are others on this list who would as well. Who else is game? This seller will only ship to the US, so someone within the US (I'm not) would need to receive them and reship - I'll happily pay a few $ on top of the onward postage for the trouble. Any volunteers?

FS: QBUS boards, 4K memory boards, Sharp PC-3000 items

by listmailgoeshere＠gmail.com

Hi list, I have the following for sale: 1) 4 * QBUS board: DEC "A/D FOR 1103 5012094E-P2" DEC "4 CHANNEL D/A A6001 5012107 DP4" DEC "PROG REAL TIME CLOCK M7952 5012108B" DEC "M9060 5017109" load board 2) 2 boards marked "4K MEMORY BOARD FOR 118 NICOLET INSTRUMENT CORP 000-7488-04 10/14/75" Each one contains 40 ICs marked "TMS 4060JL BP7901" and then 15 chips' worth of 74-series logic. One of these boards seems to have been used for spares or something, as it's missing all its resistors, capacitors and one of the TTL ICs. The connector on these is an 86-way 0.1" edge connector. 3) The original box and manual, plus original Sharp (still boxed) Laplink cable, for a Sharp PC-3000. There is a PC-3000 *in* the box, and you can have that too, but it's got a smashed screen. Probably still works other than that, no promises though. There's also the (likely unobtainium these days) adaptor from the PC-3000's mini-serial port to an actual DE9 connector. Please make an offer by private mail if you want any of this. I'll ship anywhere, but you pay the shipping. Items are located in West Yorkshire, UK. Ed.

microvax 3800 available in NE ohio

by vax9000＠gmail.com

Hello people, I am dumping my small collection. If anybody is interested and is able to pick it up, you are welcome to get it. I do not ship or store. It was a complete microvax 3800 (upgraded to 3900) but I took the KA655 to fix my barebone 3900. You get the computer with RA7? DISK, DSSI disk controller, memory, ethernet card, tape card and tape drive. Plug in a KA655 and it is ready to go. vax9000 ----------------------------------------------------------------------------- Ever watched "American Beauty"?

Any word on OS/2 for PDP-11?

by aek＠bitsavers.org

My last comment on this bit of absurdity is >from Bob Supnik, who would have been in the position to know as one of the senior VAX engineers in the 80's. I didn't even bother asking if a PDP-11 version of OS/2 existed. -- No, there was no VAX version of OS/2. And a luggable wasn't done on my watch. No idea who Dan Gahlinger is, either. Does he have a "VAXmate" (which was really a PC, and could run OS/2) confused with a VAX? Now, if he means "luggable like a Rainbow", which was just a PC chassis without keyboard or monitor, then there were tons of those - every VAXstation looked more or less like a Rainbow, since they all came out of the same industrial design group ("any color you want, as long as its beige"). If he means a real luggable, with a built in monitor and keyboard, I never saw one. But the VAXstation 2000 was fairly small, only slightly bigger than a DECmate, so repackaging it with a fold out keyboard and a small monitor would have been possible, if some government group wanted one. /Bob

HP-21MX bootstrapping?

by Tim＠Rikers.org

ok, been meaning to actually run something more than the little assembly test apps on my HPs. How do folks bootstrap systems? I've got 2 working HPs (HP-2108A and HP-2112A) and HS-TERMINAL (ie HP-12531B) and I can get lights to light up with a 2400 baud connection and this snippit running: 0001* set to TTY I/O number 0002 00011 SC EQU 11B 0004 00040 ORG 40B 0005 00040 106700 LOOP CLC 0 Turn off I/O interrupt system 0006 00041 060051 LDA TTYIO Load A-register with control word 0007 00042 102611 OTA SC Output control word 0008 00043 103711 STC SC,C Set control, clear flag 0009 00044 102311 WAIT SFS SC Wait for flag 0010 00045 024044 JMP WAIT Loop till ready 0011 00046 106511 LIB SC Input data word 0012 00047 106601 OTB 1 Output data word to switch register 0013 00050 024040 JMP LOOP Next char 0014 00051 160000 TTYIO OCT 160000 TTY input and print control word LOOP 000040 01/0005 -- 01/0013 SC 000011 01/0002 -- 01/0007 01/0008 01/0009 01/0011 TTYIO 000051 01/0014 -- 01/0006 WAIT 000044 01/0009 -- 01/0010 4 symbols 14 lines assembled, 10 words generated 0 errors, 0 warnings (also online as http://rikers.org/hp2100/ttyin.lst) so what's next? Is there a tape loader for use over a 12531? Also, I'm using a modified version of the perl assembler. I'd like to actually use the native HP assembler under SIMH. The HP / CHM agreement should allow for at least this much bootstrap information to be shared. I'm happy to put up bootstrap instructions and tape images if someone can provide them. I don't have any other peripherals tested out yet. Not sure why my real paper tape reader is not working yet. My paper tape punch is a long ways >from working and it's not HP equipment anyway. I've got tape images that work in SIMH like the HP-Basic. Just want to see these work on real hardware by loading them over a serial line. There are quite a few HP collectors out there. How do you folks boot up your hardware? ok, I could get an HP-7970 9 track, but I don't have that either. It would seem useful to be able to bootstrap any given tape over serial. I know it's only 2400 baud, but just about every HP collector should have the needed hardware. :) Help me out! PS: Some nice list owner promised to get me a CD full of stuff to get started, but alas, I'm afraid my process is never getting scheduled. Perhaps I need more of a real-time OS. -- Tim Riker - http://Rikers.org/ - TimR at Debian.org Embedded Linux Technologist - http://eLinux.org/ BZFlag maintainer - http://BZFlag.org/ - for fun!

IBM RT 6150?

by silent700＠gmail.com

Hi all - I've got a line on this old AIX box, with the monitor, books, etc (not sure about O/S media but I think that can be "found.") Any opinions on it? Any historical significance ("first machine run ____," etc?) It's cheap, but it will have to be shipped, which may not be cheap. -- j

Group buy of 1541-III PCB's?

by healyzh＠aracnet.com

I know there was some interest in 1541-III PCB's recently. Vincent Slyngstad and I have been discussing this since that time, and he has done up schematic in Eagle CAD and has the initial board layout done (actually three different versions using different SD Sockets). The big difference between this and the original design is that it uses through the hole parts wherever possible rather than surface mount parts. I'm trying to find out if anyone here will be interested in boards. I have a design question or two for anyone that is interested. Additionally, I'm looking for anyone familiar with SD Sockets, as neither Vince nor I are, and a couple questions have come up on the socket placement. Information on the 1541-III can be found at the creator, Jan Derogee's website http://jderogee.tripod.com/ Zane -- | Zane H.

It's been done, however, the problem is the driver as bare IDE or CF is NOT MSCP not is it DL, DX, DY or RK so a driver is needed and noone has apparently stepped up to do it. I beleive its fairly straight forward work but never having done it but having seen drivers like DD and DY They have a structure that must be held to. SCSI is actually harder to talk to than CF or IDE, I have done that for CP/M and SCSI is a pain as you have to deal with the SCSI chips and their particular protocal. MSCP is a complex protocal whols primary job is to create a logical abstraction hardware from the software and I don't think an atmel uP is enough and definatly enough ram plus enough is not known to create it(MSCP) from scratch.
