SuperKIM

by spectre＠floodgap.com

I'm cleaning out my closet and came upon (again) one of my collector's mysteries, a microproducts (sic) Superkim (or SuperKIM). This appears to be an evaluation board (everything is socketed) that slots into a larger chassis. It has a Rockwell 6502 and several 6522s, and a tremendous amount of wirewrap on the bottom which may be after the fact. Anyone ever encountered one of these? I have the manual for it but it seems to be more of an experimenter's board rather than a substitute for the KIM like the AIM-65. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Don't Be Evil. -- Paul Buchheit --------------------------------------------

Diloq MQ 606 manual wanted

by jdr_use＠bluewin.ch

I would like to reuse some former PC MFM drives for use in a PDP11, with a Dilog MQ606 controller. Anyone know of an online manual on this controller ? Jos

Cromemco Z2-D system and accessories in Seattle, WA - Wish to donate

by wysoft＠hotmail.com

Greetings, I'm posting here to inquire about the possibility of someone wanting to take this old Cromemco off my hands. I appreciate all that it is, and it has some family history behind it, but no one else in my family seems to want it, and it's far beyond my era of interest, so... Here we are. The system itself is in good physical shape - no damage, structural or cosmetic. My late uncle also built a wooden rolling base for the system, which includes additional power outlets for peripherals, and a remote reset switch. He developed software for Boeing on this machine, and I imagine it was pressed a lot. Based on the advice of others, to avoid damage to the unit I have not powered on the unit or plugged it in. Hardware installed in unit: CPU board, 4FDC, 8PIO, two 64KZ boards Additional hardware, still in boxes: 16-FDC, four 16KZ boards, two WANGCO floppy drives Zenith Z-29 terminal is also included if you wish, though I had originally intended to keep it. I used it over a year ago to do VAX stuff, and it still worked. There is also a printed manual. Printed and bound documentation: Word Processing System, Cromix Operating System, Database Management System, Cromemco Extended BASIC, Z-80 Macro Assembler, Link and Lib, CDOS, FORTRAN IV, Cromemco System & Components, Cromemco Trace System Simulator, Zilog Z-80 Tech Reference There's also a huge stack of assorted manuals, catalogs, etc. My uncle really kept everything. Also included are a fair amount of my uncle's scribblings and notes, some of which might be helpful to you. Software (almost too much to list): CDOS 2.36, CDOS 2.54, Z80 Macro Assembler, Word Processing System 4.06 & 6.0, FORTRAN & utilities, CROMIX, Database Management System 3.05, Database Report Language 1.0, Relocatable Assembler, BASIC 5.2, 16K Extended BASIC, COBOL, Database 0.02 (?), Drivers (?) I'll gladly snap photos if you wish. I would really, really like to avoid having to dispose of this stuff. I never knew my uncle, but if I hadn't taken this stuff from where it sat for the past twenty years in my grandmother's basement, it would have ended up in the trash. Hopefully someone here can make good use of it. I'm in Bremerton, WA. I'll drive to meet you within a reasonable distance. Please let me know if you have any additional questions.

Programing PDP-8 assembler - details

Like others mentioned, you have VTEDIT, which you can find at ftp://ftp.update.uu.se/pub/pdp8/os8/teco8/ for instance. I also have VISTA, which is a nice editor that can handle various different terminals. However, for some reason I can't seem to find it in our ftp archive right now. I was pretty sure I put it up there at some point. But maybe someone else knows a location where you can find it. Johnny

Why use a line editor? There are several full screen editors for OS/8. Really fast and nice ones. Johnny

I've uploaded some earlier versions to http://bitsavers.org/bits/DEC/vax/ultrix to show you what they should look like. I probably should do the same for the 4.x versions he has.

Programs needed? PAL8 is the standard assembler, and ABSLDR is the normal linker/loader. The system calls, information about file system stuff, and all other information you need to write programs in assembler is documented in the OS/8 SOFTWARE SUPPORT MANUAL Don't know if it's available online, but I would suspect so.

In all fairness, there is no such limitation on the size of disks on PDP-8s. OS/8 have a limitation on disks being no more than 4096 *blocks*, but that's a limitation in that OS, which is based on the fact that just one word is used to specify the block number for device drivers. Larger disks (which weren't that unusual) had to be presented as several logical disks to the OS, in order for them to be fully used. So an RL02 (as an example) looked like five disks to OS/8. RL0A, RL0B, RL0C, RL0D and RL0E. All about 2M each. As for multi-tasking - no, that was/is not dog slow. Most of the time it was perfectly fine even for several interactive users in parallel. Johnny
