Sadly neither seems to be among the files I have copied. I could yet check Intel Dec 1995 Data on Demand discs I happen to have, and do have here, but they are cumbersome to handle as they use a proprietary format requiring a DOS app to access, and yet more hassle to get anything exported (assuming I can recall how I did that many years ago), so it'll take a little.

The February 1998 CD-ROMs contain a copy of the Intel Flash SOFTWAREBuilder, which appears to be related to but different from the FLASHBuilder tool.

Besides; there's not much point: the big adantage of using V6 is that one can use the V6 tool-chain to prepare Mini-Unix binaries; XV6 wouldn't allow that. If all one wants to do is get files in or out, there's already a program (compilable with gcc, that uses Standard I/O) to read files out of a V6 filesystem. If there was any good need, it could be extended to write (although that would be non-trivial). Noel

Eric wrote: > There was IBM APL\1130 version 2, introduced in 1969. It's actually sorta annoying when you discover how much HP copied from IBM in those days. The first giveaway is that APL\3000 has a backslash in the product name when everything else was a forward slash as in BASIC/3000, FORTRAN/3000, and even RPG/3000 (which was another functional copy of an IBM product), and of course this is likely because of APL\360. Most people, even inside HP, started calling it APL/3000 almost immediately though. APL\3000 is supposed to be a functional superset of IBM APL SV (APL\360 with Shared Variables etc.) and HP advertised it as such. The other one that took me a while to notice is the HP 2641A APL Display Station that came out after the 2640 and 2645. That out-of-order numbering was kind of interesting until you discover that the IBM Selectric-based printing terminal with the APL type ball was the IBM 2741 (sigh).

I don't know all of what's missing; some accounts claim that it almost had feature parity with APL\360, except the circle function, which admittedly is a rather significant omission. I would be surprised if the circle function didn't make an appearance in later releases. In any case, that's awesome work resurrecting it! I used a 3000 a little bit in school from 1982 to 1984, but unfortunately it was mostly used for RJE to a System/370 elsewhere, so I didn't learn too much about the 3000.

TIFF is only a container format ("Tagged Image File Format"). TIFF does not
define any one compression. It in fact can contain either lossy or lossless
compression, or even uncompressed images.
For black-and-white documents (text and line art, no grey scale), it used
to be somewhat common to use TIFF Class F Group 3 or Group 4 fax format,
which is lossless, but TIFF can also contain DCT-compressed images
(equivalent to JPEG).

Good basic idea (using a different system to build on), but there's a better/easier approach (in the same basic vein): bring up V6, and mount the RK pack with Mini-Unix on it (it's a V6 file system, so is mountable); V6 is rock solid running under simulators. The V6 tools can I'm pretty sure be used directly to build new Mini-Unix kernels; user program can I think use the V6 C compiler, but I'm pretty sure not the standard V6 linker (the Mini-Unix linker loads tham at the non-standard address used by Mini-Unix).

Shipping via USPS Los Angeles is STALLED
I have a vintage computer sitting in the LA USPS since 9/17, with no further updates. I have read in the local papers there that the entire post office has ground to a halt. What's going on there? I have never heard of anything like this. I assume my package will survive but think of the zoo there if they've been stacking packages for TWO WEEKS. I'd strongly suggest not attempting to ship anything out of LA for the time being. WOW. I know people complain about the post office, I am not complaining, just stating the facts. Normally the USPS is reliable. They must really have overall problems in southern CA due to the fire and related management issues. BIll
Re: ISO: Motorola MDP-1000 info/software
whats the story on this...i see items but no pix. also check your spelling on Motorola; Instrmentation and Control, Inc. that is in the index. let me now if there is a photo group for this at least with the covers I always wondered if it was just a 12 bit computer or if it was software compatible with pdp-8? I wonder what else this division of Motorola produced there was a teleprinter they made... Here is the link to the teleprinter it is filed under gov div. http://www.smecc.org/motolola_government.htmi think i got the 12 bit computer manual from same person.

Re: ISO: Motorola MDP-1000 info/software
i may have posted a link yes i k ow cctalk is lacking in image handling. maybe some day that will change. it was years back. it may be something josh has already... but maybe not. neat he found the hardware!

Re: ISO: Motorola MDP-1000 info/software
Josh I posted photo of a manual we had a long time but not too long if you want to search the cctalk here.. Also always wondered which plant built in... is this same basically as a pbp 8 or is it just that they are both 12 bits? Thanks Ed# In a message dated 9/29/2020 11:26:36 PM US Mountain Standard Time, cctalk@classiccmp.org writes: Hi all -- This is a long shot, but I was curious if anyone might have information onthe Motorola MDP-1000 minicomputer. I picked one up recently and I'mworking on restoring it. Of particular interest is the power supply, whichis external to the processor and which I am missing. I think I have thevoltages worked out (+/-5V and +/-15V), but there are a number of othersignals on the power supply connector that I'm unsure of at the moment. I've put a few pictures up here: https://1drv.ms/u/s!Aqb36sqnCIfMpIVYmzKjFnsT3nHh8w?e=b2iqqv I'll note that this isn't technically an MDP-1000 -- it's labeled as anMDP-6650 on the rear. I suspect that this is a ruggedized version of the1000 intended for harsher environments. The front panel of mine appears tobe identical to the drawings of the MDP-1000 in the manuals I have. It also came with a binder of documentation (but alas no schematics) thatI'll be scanning soon and getting off to Al. It's an odd little system --5 12-bit registers, a 12-bit ALU, and a 12-bit Instruction Register, butthe memory is 8 bits wide. Instructions are packed into two bytesnormally, but there's a special 64-byte region of memory that can be usedto store "shared bytes," which allow encoding certain instructions into asingle byte, taking the other byte from the shared region. I've never seenanything quite like this. I wonder why they didn't just use 12-bit widememory... Also the process for using the front panel to examine and deposit memory isinsane. Here's the instructions for reading a memory location; it's 10steps. Depositing is 17. https://1drv.ms/u/s!Aqb36sqnCIfMpIVWThgwlxgCMQo59A If anyone has anything on this, let me know. Not expecting much, but it'sworth a shot.- Josh
