All:
I?m looking for the two following Dr. Dobb?s articles on the Mac:
::Jan 1985 "Fatten Your Mac" by Thomas Lafleur and Susan Raab
::Sep 1985 ?SCSI Your Mac, in MAC Toolbox? by John Bass relating to
adding a home-brewed SCSI interface to the Mac 128/512.
I have one of the DDJ article compilation CDs (Volume 11) but it only
starts at 1988. I would be grateful if someone with access to these issues
could make scans of them or point me to an on-line copy. Googling this
morning didn?t produce much other than TeX indices.
Thanks!
Rich

I think fatten your mac had you piggy back your 64K drams and
bring out CS? to the address decoder. I still marvel at the price
of a MAC and it had only 128K memory.

Nope. DRAMs don't have a CS signal, they have RAS and CAS. Also, there
wasn't any decode for another bank of 64K DRAMs. The upgrade was to
replace the DRAMs with newfangled expensvie 256K parts, and add a
74S257 multiplexer for A8. I don't recall whether the board had
pin 1 of the DRAMs wired together; if not you'd have to do that
as well.

Back then you got a paper listing and all that stuff. Not like now
where you buy the MAG so you can order a CD rom with the CODE
that only works under some unfordable windows development
system.

It's funny you said that. I found the original invoices for my Fat Mac.
$2495 in 1985. $500 for a 1200-baud modem. $800 for an ImageWriter I. $500
for the external floppy drive. I remember I got a discount from the store
(NYNEX/DataGo) because by father worked at NYNEX in the early 80's.
If I have time, I'll scan it and post it on my Web site.

I was going from memory before so I dug out the invoice for my Mac512k:
Date: 9/12/85
Purchased from: NYNEX/DataGo (this was NYNEX's business center retail chain.
NYNEX was the merged phone companies of New York Telephone and New England
Bell after the 1984 consent decree which broke-up AT&T)
Mac 512k - $2795
Imagewriter 80CO - $545
IWI Cable Kit - $50
Mac External Disk - $495
Mac Numeric Keypad - $70
Mac Modem 1200 - $495

MacTerminal - $99
MSWord Mac - $195
Mac 68000 PDS - $195
MSBASIC - $150

That's $5,658 and it didn't even include a hard drive!

Yes, but those were just 1985 dollars, not... oops, wait a minute...
wow, that was expensive! :-)
Of course, the IBM PC and PC/XT were pretty expensive back then too,
but the Macintosh definitely commanded a premium price.
