596.0. "(questions :topics '(xlisp hard-disks))" by Z::TENNY (Dave Tenny | DTN 225-6089) Thu Jul 16 1987 03:34

I'm interested in doing the following:

  Getting the source for XLISP 1.7 (or 1.8 when it comes out)
  and modifying it to allow calls to Intuition routines in a fashion
  similiar to the way Vax Lisp allows calls to UIS routines.

  I find this to be a neat way of writing fun/useful programs
  with a graphics front end.  My questions are:

  Does anyone have the source, or know where I can get it?
  Has anyone done this?
  Any ideas on the subject?


Of course, I'm not *really* ever going to get around to it.
Particulary until I join the ranks of hard drive owners.
Which reminds me, how are you hard drive owners fairing?
The reviews in Amazine Computing indicate that there is some amount
of problem with drive crashes and backup.  Are you finding this to 
be true (for one or both)?  For those of you using the non-DMA drives,
do you notice any impact on other processes when there is lots of
I/O activity from a particular process?

Thanks,
Dave

	If you can find the source, I'd be more than willing to participate
	in a joint project with you. I'd LOVE to be able to get at Intuition
	from inside XLISP.  The only real hassle would be maintaining
	compatibility with later release of XLISP; it would require some
	careful planning to make sure we didn't get stuck in a corner...

	Anybody else interested ?

Wow, how times change.  Remember when XLISP was first written.  It
was developed on a PDT-11 by a DEC employee who moved on to another
company.  A PDT is basically a very small LSI-11 (of PDP-11/03 size)
with a total of 64K of memory and two single sided 8 inch drives
(243K per drive).

    Re: .0, .1
    
    Sounds like a decent endeavor, I'm interested, but after I get my
    serial port/modem problems straightened out (I'm afraid both are
    toast, or a reasonable facimile). 
    
    Now where's the source?

596.4XLISP began on a VAXNOVA::RAVANFri Jul 17 1987 14:287
    RE: .2
    
    No, sorry, I had the office next to Dave's when he started XLISP.
    He developed the first version of XLISP on a VAX.  It may have
    been ported to the PDT using DECUS C, but he started on a 780.

596.5New DMA hard disk?Z::TENNYDave Tenny | DTN 225-6089Fri Jul 17 1987 17:148
	I spoke with Don at The Memory Location today,
	he mentioned an ad in AmigaWhirld (which I no longer receive)
	for another DMA hard disk besides the Pal Jr.
	Has anyone seen it?
	Would you post a word or two about it?

Damn! Another romantic illusion shattered!
596.7Another hard disk manufacturer.Z::TENNYDave Tenny | DTN 225-6089Mon Jul 20 1987 15:2810
	I looked in an AmigaWorld for the ad mentioned in .5,
	and found the vaporware announcement.  It might be worth
	waiting for.  
	All I remember about it was:
		Uses DMA
		List price 1099 $

	If nothing else, when it appears, maybe it will drive down
	other prices.
596.8Heeeeres XLISP!!!SQM::JMSYNGEJames M Synge, VMS Performance Anal.Thu Aug 06 1987 16:298
	I've got version 1.7 of Xlisp in 
		SQM""::PERFD1$:[JMSYNGE.PUBLIC.XLISP]

	I've deleted the examples, so you'll need to know how to use
	all the features with out reference to the examples.

596.9comspec hard drive, bootable!Z::TENNYDave Tenny | DTN 225-6089Thu Sep 24 1987 17:4715
I received a blurb from COMSPEC communications about their new hard drive
offering.  (I purchased their 2M memory board).

The  disks were in 20M and 40M flavors, and the price was a little stiff,
(  $11xx.00 for the 20M and I don't remember the 40M at all)

but,
  COMSPEC claims that the kickstart and workbench will BOOT FROM THE HARD DISK!

Anyway,
  I already have a Supra drive, but if anyone is interested,
  I'll post more accurate info from the blurb.

    List prices don't mean all that much, Dave.  The 20 meg Supra lists
    for $995, but the street price is $750-$850.
    
    As more vendors release products, prices are bound to drop further.
    
    
596.11Z::TENNYDave Tenny | DTN 225-6089Thu Sep 24 1987 20:165
Yup, I'm aware of "real" prices.  I bought my 30-meg supra from ABEL supply.
I hate to think of what the memory location would charge, even on a nice day.
