Intel does some squirrelly crap but I can assure you that unless it says 80C88 it is NMOS ( the -2 version of the 8088 is Enhanced NMOS or HMOS, but still not CMOS ). CMOS is not necessarily slow either, but at higher frequencies it looses it's low power advantage. We used SOS ( Silicon On Sapphire ) 1802s on spacecraft because of the low power, and the SOS makes it much less static sensitive and Radiation Hardened. Intel screwed us when they stepped the 8031 to CMOS ( 80C31 ) as they forgot to mention the multiple pages of errata of things that didn't work right, like Power on Reset and Interrupts.....

The 80c88's were used mostly in small laptops, no? (small being anything smaller then that Zenith big honker, w/the shocking blue display. It used a *real* 8088 IINM). A CMOS version would be slower and more prone to damage from static electricity. And it would require less power. Off the top of my head I can't think of any desktops that used them, but I may have actually ran into 1 or 2 in my travels.

Saving TU-58 Tapes

by jhfinedp3k＠compsys.to

I just received a number of TU-58 tapes. Most seem to have VAX software. Is a list of the contents of such tapes available somewhere? I want to save the files before I use them for RT-11. I have seen such a collection of VAX software before and I presume that I am not the only person to save the files. So if this has already been done, it will not be necessary to repeat the exercise. I attempted to look at bitsavers, but there does not seem to be anything much there in the way of software for the VAX. I assume that since there are hobby licenses for the VAX that all of the software is also available. By the way, the dates on the files are 1983 to 1985. Some of the contents are: VAX/VMS 3.4 FORTRAN C PASCAL Are these tapes useful? How are the files saved? Can the files be easily saved using RT-11? What is the best media to save the files? Probably the only reasonable method with RT-11 is to save all 512 blocks of the TU-58 tape as an image so that a VAX/VMS system can easily ATTACH the file as a TU-58 tape drive under SIMH. Sincerely yours, Jerome Fine

Altos 8000-2 booting, SD> DD (CPM)

by g-wright＠att.net

as long as I'm on the Altos thread. I'm trying to make some disks for another list member for the 8000-8200 Z-80 based machines. Both of my systems have floppy disk boot or write problems. So I decided to look into the easier machine which it a 8000-2. basic Z-80 , 1791 FDC and 2, 8" SSDD floppies. The machine will boot a single density CPM disk, read and format a SD disk, but dies if a DD disk is either inserted for boot or the format program on the SD disk is told to format a DD disk. These all have SD Boot tracks, then have to switch to DD, if formated in DD. I have the wiring diagrams and there is a "EN DD" coming off the PIO chip and goes to the 1791 chip, that never changes state. I would believe it would have a floppy density code on the 1st track to tell the OS what the remaining tracks are ??? (just a guess) I know the disks are OK, they can be read in another machine. ( just not copied.). i have looked at the data lines on the PIO chip and have replaced it just in case. I have scoped the started up circuit which also has the "EN DD" tied to it. (input) The software can only be copied by another Altos due to the disk layout. The boot ROM could be damaged?? but not knowing what it should read, its hard to guess. Can't be much there just a 2708. Anyone have a 8200-2 that can read the ROM on, or any ideas. The manual is on Bitsavers under Altos, ACS8000 users manual. The motherboard is a 8100 series (double density) Has 8000 SD, 8100 DD and 8200 in the manual. - jerry Jerry Wright g-wright at att.net

Altos & M/PM manuals available

by silent700＠gmail.com

I have a large box of Altos materials here that I would like to find a home for. About half of it is standard bound books, which will go first. The remainder is ringbound and I am going to attempt to scan them. In addition to manuals there is a lot of dealer sales material, including about a dozen issues of the monthly sales newsletter "ALTOgether." The first lot includes manuals for the Altos 486 (which was really an 80186,) Altos 586/986, Altos XENIX, and a few for the M/PM-II and MPM-86 operating systems. A couple books are a bit warped from sitting in a box too long, but they're all in pretty good shape otherwise. All in all about 16lbs of books. Free for the cost of shipping (Media Mail rate shouldn't be too bad) from 60074. -j

Tektronix 4225 -- is it an X terminal?

by legalize＠xmission.com

See ebay item # 360132413754 That listing just includes the base unit, but thankfully has closeup pictures of the connectors on the back. It looks like it takes AUI ethernet or RS-232 and outputs RGB video. Anyone familiar with these puppies? I've not seen one before. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Any have a CMD CQD-200/M manual?

by toby＠coreware.co.uk

Hi, Has anyone by change got a manual for a CQD-200/M (QBUS SCSI controller). The device is pretty similar to the CQD-220/M, which has a pdf on bitsavers, but jumpers are alas not the same and I just want to check I've got everything set correctly and enable its bootstrap I've fired it up on my PDP-11/23+ with an RZ27 disk and I can indeed access it via RT-11 but I only get a 32MB (65K blocks) disk after an initialize. Does RT-11 have a 65K block limit on a disk? Thanks, Toby -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
