Intel 8088 Puns

I read that compilers had trouble to generate code for intel 8088 CPU. But when I now look up the ISA it feels like ideal for a fast CPU on a cheap PCB. The instruction set has many implicit registers, but those can be overwritten in a second byte. The 8088 has 8 byte sized registers for general purpose plus some 16 bit: BP, SP, PC . And 16 bit segment registers. I think the mov instruction has access to all of them. Anyway, one would need 4 bits to select a register and so the whole instruction would be used up just by specifying source and target register.

So a compiler would have to first compile all the instructions and this determines what variable is stored in which register. Now in multiple passes the compiler looks if the output of one instruction is needed in the next and the registers do not match. Then one of the instructions is followed by this register modifier, and the modifier is inserted as a shim.

If two local variables fight for the same register, the one with the most access gets it and the other is delegated to a free register using the second byte. In long functions with many 8bit values there may be some registers free. Long living variables may need to move from one register to another. Many of these may be combined with some copy or Load Store instruction which had to be done anyway.

Hello, I have been researching the Intel 8088 and 8086 and trying to build a small breadboard computer. The one question I still have is where does the 8088 start trying to execute instructions from, I believe that the z80 starts a 0000. I have read that it starts at FFFF but wouldn't that be the last address? so it would go backwards from FFFF?

you can't run Radio Shack programs

nor can a Commodore 64

drive read a file

you have created on an

IBM Personal Computer.

both Kaypro and Osborne computers use

the CP/M operating system

but can't read each other's

handwriting

for they format (write

on) discs in different

ways.

the Tandy 2000 runs MS-DOS but

can't use most programs produced for

the IBM Personal Computer

unless certain

bits and bytes are

altered

I'm looking for some advanced or specific operations of the Intel 8088 CPU. For example, I was wondering how the 8088 takes in a 16 bit value through an 8 bit data bus. Also, how does it interface with memory with it's 20 address pins? Finally, does the CPU access data addresses through byte sizes registers or word sizes registers? If someone could help me out, or point me in the right direction, I would be very grateful.

So...I've got a Compaq Portable I'm trying to coax into running some flavor of *nix. Obviously, Linux proper (and BSD, and Minix 3.0, and pretty much anything else that's still relevant out there) isn't going to run on the thing. Is there anything that will still run on something this ancient that's still being maintained?

Failing that, were there ever *nix-based systems designed to run on these things back in the day?

I want to build a computer using only some breadboards, an Intel 8088 processor(16-bit, 5, 8, or 10 mHz) and some cmos chips. Then code the OS and shell similar to a unix environment (or any well documented system that would best fit this processor and system). My purpose is to better understand how computers work. I'm a sophomore CPSC student and I feel that my understanding of how a computer works is truly lacking! I have this as a guide to start with but I'm not sure where to get the parts, and my logic of why this is built this way is lacking. ( http://www.cs.binghamton.edu/~reckert/sbc.htm ) I'm almost finished with the book code: thge hidden language of computer software and hardware(http://www.amazon.com/Code-Language-Computer-Hardware-Software/dp/0735611319/ref=sr_1_1?s=books&ie=UTF8&qid=1428172220&sr=1-1&keywords=code).

Any help or suggestions where to start would be well appreciated!

Hi There,

I have a wierd hobby, collecting old CPU-s.

This is the oldest one i own. Intel D8088. Never used and never tried, I wasn't even born when is was released. Did you guys used it in the first "PC"?

The IBM PC was based on this chip, so we can say this was the first Master Race element.

So, I have several vintage DOS based machines 8088 through early Pentium's. I got tired of setting up msclient and its pretty poor copy speed. mTCP ftp is nice but it doesn't make it easy to sync folders or drives.

EtherDFS allows you to mount a share on a server running the ethersrv on a linux box. http://etherdfs.sourceforge.net/

If you don't want to setup a linux box and get ehtersrv up and running just download this random virtual machine off the internet! http://tomsie.co.uk/ethersrv/

Now you can then point ethersrv it to a file share using samba on your local windows machine or another machine on your network, or copy files to the VM via a samba share it exposes.

On the client machine you just need two things, a network card and a floppy drive (I use a gotek). I use a boot floppy with the packet driver for the network card, in my case I use an intel TP16 since it works on both 8-bit and 16-bit machines just fine. Next you need to load up the EtherDFS driver. I use a simple command line EtherDFS :: C-E . EtherDFS will look for a packet driver at 0x60 and some other ports automatically it will also search the network for a valid server and mount the remote drive named C to a local drive named E. Next I use another tool xxcopy16 to copy new files to the empty drive or to sync an existing machine for updates. It's like xcopy on steroids. The version I use 2.93 I think is the last one that supports MSDOS 6.22 http://www.xxcopy.com/img/

Unfortunately, you can't buy it anymore but you can find a copy in all the normal watering holes. It supports xcopy's command line options plus 160 more. I generally use /BI and /YY to skip files with the same name and size but that is the tip of the iceberg.

It is much faster than using msclient and to me, more convenient than mTCP's ftp. I still use both msclient and mTCP for other stuff but initial setup and file copies EtherDFS is my go to.

Hopefully someone else finds this as useful as I have.

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

The nurse asked the rabbit, “what is your blood type?”

“I am probably a type O” said the rabbit.

Santa visited a datacenter (or two) to bring you gifts of good cheer! All the drives have been low-level formatted from 520-byte to 512-byte sectors for use by normal x86 hardware and LSI IT mode controller for use by FreeNAS/TrueNas, etc, etc where you need direct access to the drives. All the disk shelves have dual SAS expanders I/O modules for proper multipathing to the drives. In addition to the low-level formatting all the drives have been securely erased. Add your favorite IT mode LSI external controller and you're ready to go!

I am located in Independence (Cleveland) Ohio right off of I-77 & Rockside Rd. I am only allowing pickups on Monday's during normal business hours (8:30am-3p). I prefer cash/PayPal. Local pickup only, I'm not shipping generally the shipping cost of a large box or freight does not make finical sense given the dollar amounts of this stuff. My target was $10/TB.

I'm willing to give volume discounts and those offers will be prioritized to the top just fyi. Please be patient with me, I have a feeling there will be alot of messages to sort through with a lot of this size. Additionally, I am not accepting pickup until January 10th because of Christmas and New Year. I will not be in the office until then. Additionally, for the larger items I am willing to accept a PayPal deposit to secure the larger items if desired.

Alot of great jokes get posted here! However just because you have a joke, doesn't mean it's a dad joke.

THIS IS NOT ABOUT NSFW, THIS IS ABOUT LONG JOKES, BLONDE JOKES, SEXUAL JOKES, KNOCK KNOCK JOKES, POLITICAL JOKES, ETC BEING POSTED IN A DAD JOKE SUB

Try telling these sexual jokes that get posted here, to your kid and see how your spouse likes it.. if that goes well, Try telling one of your friends kid about your sex life being like Coca cola, first it was normal, than light and now zero , and see if the parents are OK with you telling their kid the "dad joke"

I'm not even referencing the NSFW, I'm saying Dad jokes are corny, and sometimes painful, not sexual

So check out r/jokes for all types of jokes

r/unclejokes for dirty jokes

r/3amjokes for real weird and alot of OC

r/cleandadjokes If your really sick of seeing not dad jokes in r/dadjokes

Punchline !

Edit: this is not a post about NSFW , This is about jokes, knock knock jokes, blonde jokes, political jokes etc being posted in a dad joke sub

Edit 2: don't touch the thermostat

I'm a software engineer, and I would like to learn how to make redstone machines in Minecraft. Because, well, I wish to create a machine that has the same specs as the “Intel 8088 Microprocessor”.

Do your worst!
