Hi Sam and all, At 01:30 PM 2/24/99 -0800, you wrote: > >Does anyone have the data sheets for the 1101 RAM and the Intel 8008? I >need both.

For the 8008, the best is the mcs8 microcomputer set users manual. Someone on the list just found one in the last week or 2. I probably have a "condensed" data sheet from a Intel catalog as well. The mcs8 book is about 100 pages. The instruction set would be only 4 pages or so. I might have some data >from the Canadian company that second sourced the 8008?? > >Anyone know where 1101 RAM chips are for sale (if at all?) A few years ago I searched all over the place, not only Halted, James, ACP, and any other advertisers in early Byte magagines that might still exist, but the "obsolete ic" house resellers too. Remember the ads for "8008 +8 2102's"? I only found about 3 "tubes", but may not ever use them as wire wrapping 8 chips give only 256 bytes. How many do you want? Can't you find this stuff by the barrel and data sheets by the ream there in Si valley :-)? ..Like a west coast "Poly Pac's". No I don't expect to find a Mark 8 or Scelbi, so am moving slowly to building a 8008 system. I did finally find a copy of "Microcomputer Design" by Martin by interlibrary loan :). Abebooks, etc never found it. It is loaded with 8008 stuff with things like all timing, a 9 chip 8008 system, etc. They also sold the "Mike" series of microcomputer boards, but I have never seen one except pictures in early Byte's. I also tried to find Martin or his company (In Illinois), but no luck. By the way, searching, I found a rumor that Intel was going to come out with a support chip for all the control logic for the 8008. I have seen no indication they did, just went on to the 8080. > >Sellam Alternate e-mail: dastar(a)siconic.com >--------------------------------------------------------------------------- --- >Always hasslin' the man. > -Dave

V35-RS232 cable?

by edick＠idcomm.com

I remember at least one contact with this sort of cabling arrangement. The v.35 normally uses a distinctive rectangular connector while most manufacturers like the cheaper 'D' connectors. The use of the 'D' connector has more to do with cable-assembly cost than anything else, and it may not be assumed that there is any implication of signal compatibility. If you intend to play with the v.35, you may want to look at the standard before risking the health of your interface hardware. I haven't looked at it in years, but IIRC, it's a differential arrangement at ECL levels or something on that order. I say this because I seem to have seen ECL logic used to generate the levels in at least one piece of equipment. I don't much regret that I don't remember the details. Now that amateur ISP's are running high-speed telecom interfaces, e.g. DS-3, from their basements, we'll undoubtedly see this one more often.

Another NEC APCIII question.

by jolminkh＠nsw.bigpond.net.au

The APC III was not IBM compatible at all in it's original form. It had a special version of DOS and the floppy drives are _Quad_ density not double density. When NEC later saw the error of their ways, they offered a special card called an SLE that when installed allowed the machine to run standard IBM compatible software. This came with another version of DOS, which I think was also specific to this machine for booting purposes. SLE stood for Software Library Extender. I think the special card had it's own 8088 cpu. APC III's were heavily marketed here in Australia and were once very easy to find. I have a number in deep storage (ie too deep to get out and look at easily). NEC also provided financial incentives for software developers here and I have come across several cases of startup companies built on these incentives, all now gone though. I think NEC learned about compatibility the hard way. To get your machine going the first question is whether you have the SLE card or not. The second question is whether you have the correct monitor. I don't think normal IBM style monitors will work.

General info on HP2000/1000 lineage..

by jlwest＠tseinc.com

Someone just asked me... >Hmm...what is the difference between the 1000 M-series and the 21MX >M-series? Paint? I thought my response might be of interest to others, so here's the scoop... The oldest systems in the "1000" series are the M series. They consisted of the 21mx 2112a, 21mx 2108a, and the 21mx 2105a. Later HP introduced the E series with the new 21mxe 2113a and 21mxe 2109a boxes. The E series did not replace the M series though. Then there was a major revision to the power supplies used in the cpu which was indicated by the B version (21mx 2112a became 21mxe 2112b, 21mxa 2108a became 21mx 2108b, 21mxe 2113a went to 21mxe 2113b, and 21mxe 2109a went to 21mxe 2109b). The 21mx 2105a stayed 21mx 2105a though. Finally there was the introduction of the F series with the 1000F 2117f and the 1000F 2111f. When the F series was introduced, all the systems became known as 1000's model such and such, with different designations. So finally there was the HP1000 F series 2117F, the HP1000 F series 2111F, the 21mxe 2113b became the 1000E 2113e, the 21mxe 2109b became the 1000E 2109e, the 21mxe 2112b became 1000M 2112m, and the 21mx 2105a finally changed to 1000M 2105a. More to the point, most of the upgrades along the way in a given branch were related to the power supply, the addition of more instructions to the instruction set (most related to better memory management), and faster memory boards. The HP 2000 systems did not designate a particular cpu. HP2000 or access, 2000a, 2000b, 2000c, 2000c', 2000e, 2000F (option 200/205 or 210/215), and the third party (NON-HP) 2000G designated a particular combination of peripherals. The hp2000 family generally used the pre-M series 2114 or 2116 cpu's. Later the 2100A and 2100S cpu's were used. Finally, even though HP still used the 2100 cpu's, many customers switched over to the 21mx 2108 and 21mx 2112 from the M series because they were slightly faster and used the new semiconductor memory. Few did setup HP2000 on the E series because they were faster enough to introduce time dependent problems in the TSB code. Generally the HP2000 designation meant the system was running TSB (Timeshare BASIC) which is my particular target of collecting since it was the first computer system I ever learned. If the same hardware was running DOS/RTE, etc. is was called an HP 1000. Hope this helps! Jay West

Looking for RT-11 Documentation

by mcquiggi＠sfu.ca

Hi Group: I have absolutely no RT-11 documentation, although I have two systems running it (both 11/23s). Does anyone have any online documentation on the command language, configuration, device drivers, sysgen, etc? I'm fumbling around without it. I couldn't find much on the usual sources. An online intro, users' manual, or similar would be helpful. Thanks in advance, Kevin ========================================================== Sgt.

HP3000/2000/1000 emulators?

by jlwest＠tseinc.com

Okay - I got off my behind and looked it up in my favorites folder ;) The URL for the emulator is: http://oscar.taurus.com/~jeff/2100/index.html When you get to the website, notice there is a roughly 17 tape paper tape set for something called MSU 4 user Time Share BASIC. NOTE THAT IS NOT "TSB". The msu stuff is greatly stripped down - basically supports a TSB like basic and saves to/from paper tape. It is however, quite interesting to see how they wrote their interpreter. Even used the chebbychev transformations....:) Jay -----Original Message----- From: KFergason(a)aol.com <KFergason(a)aol.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Thursday, February 25, 1999 10:15 PM Subject: Re: HP3000/2000/1000 emulators? >If anyone does find it, please post it.
