Sorry, just had to ask about the picture this thread is painting. ;-) I'm just SO GLAD that technology has moved forward! Punched cards, paper tape, even the old 1/2 9-track magnetic tape were such a pain! My old microVAX is right next to me, it was SUCH a hot machine in 1986 when I got it. Now, it is 1000 X slower than my desktop, and that is a literal performance measure! Jon I have a TRS-80 Color Computer 3 in the basement, running right now because me a fellow in .au land are trying to sort out the remaining errors in building its os to run on ALL the variations of the 'coco' that the shack several other vendors were selling back in the '80's. Mine is a bit hot rodded from the stock version which came with 128k of ram as this one has 2 megs of dram in it, and it was found by us, the users, that the hitachi aftermarket replacement for the motorola MC6809EP, the HD6309EP, wasn't a clone of moto's masks, but a from the ground up reverse engineered version done in CMOS that had its microcode map filled up with additional, much smarter instructions. Transplant one of those into the coco, and re-write the OS to take advantage of it and its nearly 200% faster without playing with the clock speed. I had a hand in that conversion myself, and even wrote a new driver for it to handle a serial mouse since the OEM shack mouse is spastic when its feeling good. Mine also has a pair of 1Gb (huge) scsi drives on it, so storage is definitely not a problem. But today, we actually build the OS on a linux box, which takes this one about 7 minutes. That OS is a smaller version of linux, 7 or 8 years before Linus went public in '91. And its why I don't touch a windows machine without sterile gloves, I don't want to take a chance catch any of that 10 day old carcass's bugs.

No problem..

How do you calculate the diameter of the spool? Number of bytes divided by bytes per inch gives length of tape. Length of tape times thickness of tape gives the area of the tape as viewed from the side. (10 bytes per inch, and 0.1mm thick, from the Wikipedia article on paper tape.)

I had a VAX 11/780 system in my suburban living room. I rescued it from a local hospital that was going to be forced to pay $6000 to have it hauled away as toxic scrap, before commodity prices went insane and the thriving metals recycling market emerged. The VAX occupied almost my entire living room, including the CPU, line printer, control console and the two hard disk drives (each of which was larger than a commercial clothes washer and could store a whopping 256 Mb of data. I was forced to dispose of the VAX a few years later as a requirement of getting married. Well, my MicroVAX II was bought as a new board from a broker in 1986, and ran for 21 or so years, and still works. The backplane got flaky, and finally the hard drive quit. When I got it, it was awesome, so far ahead of the crummy PCs at the time. But, the PCs eventually surpassed it. But, for crazy stuff, a friend of mine actually bought a PAIR of 370/145's. I bought the memory box from one of them, and was planning on using it with a bit-slice computer of my own design. But, software development for that system was going to be a SLOW process. So, eventually, the MicroVAX ended up in the memory cabinet. Here are some pictures of it. http://fp1.centurytel.net/gklittle/ibm370.htm (The pic that says I am in it is wrong, that is another friend with much darker hair.) The memory cabinet shown is like the one I put the Vax into. The 780 you could at least in theory run on a residential service, the 370/145 needed a 17 KVA motor generator set.

Probably just fine in the winter but not so nice in the summer unless you live in MT where the standard definition of summer is: any day between the 4th of July and Labor Day that is doesn't snow is summer. A VAX 11/780 wasn't bad. TTL and 74S-series chips, DRAM memory. A basic system was probably not much more than a KW, maybe even less.

Ha! I had a VAX 11/780 system in my suburban living room. LOL, That had to be one HOT living roomWe are dismantling the subfloor ac units now in at work server room since we longer need that kind of cooling for servers... Man, times have changed quickly --- I've never had the 'pleasure' of working with such old hardware, but I've seen it not even getting one bid at auction for scrap. A complete one of those IBM tape drive arrays, original price almost a third of a million dollars, size of all the machines in a laundromat, capacity not even 2 gigabytes. No Sale. IIRC 2 gig USB sticks were the latest thing at the time. Someone in IT probably remarked We could replace all this with a single $100 USB stick... and the bean counters said Make it so!. Another one was a massive hard drive rack, about half of which was power supplies and cooling fans. The drives were all pulled and stacked inside the scrapyard building. If they'd been something normal like SCA80 instead of weird proprietary IBM I would have bagged a few for the vintage Macintoshes I had. 9 gig is massive storage for Mac OS 8 and older. I counted up the drive slots, times 9.1 gig... it was a one terabyte array! 500 gig single drives had just been introduced that year. That hulk had most likely been replaced by one rack box with a RAID5 array of four 500 gig drives. Imagine the power bill reduction. ;-) -- See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.

This would actually help. thanks! - Michael Sorry, Michael. I promise not to reminisce in this reply no matter how good it feels to retreat to happier times in my life. I don't have any candidate programs to share but I do have a thought. It seems likely to me that many if not all the biggest programs are either 1)G-Code generated from processed scans (of 2D images or 3D artifacts) for use on traditional mills, or 2) G-Code generated from 3D CAD models (or, again, from scans of 3D artifacts) for use on 3D printers. In today's environment, the latter programs typically contain an ordered sequence of slices of the artifact to be printed which suggests a possible strategy for dealing with their size. I'm less clear about likely characteristics of the former but it strikes me both types of programs could/should be considered as special cases in your analysis. Just my 2cents worth (which was worth more back when I was...oops, I promised).
