    Reverse Engineering the Macintosh SE PCB & Custom Chips for 1:1 reproduction

    Well if those Maxells aren't already exploded from sitting in inventory they must have something good about them!  I have to admit, it's tempting to see leaded solder-in batteries being sold... yeah you could just solder in another battery for a more authentic looking board, but it's totally...

    Reverse Engineering the Macintosh SE PCB & Custom Chips for 1:1 reproduction

    `OUTA` and `RTXCA` look suspect, `RTXCA` will always be one with that logic so apparently you cannot enable synchronous modem use?  Not like you could ever do it in earlier Macintosh computers... I'm guessing the hardware manual's passing mention of this is because the feature was cancelled late...

    Compact Macintosh replica boxing price questions

    For reference, here are links to the previous poll and development thread on the subject.

    Which compact Macintosh models would you be interested in having replica boxing for?

    Printing handheld box replicas is within reach the of everyone, but of course then some details end up too small to be seem without a magnifying class.

    Compact Macintosh replica boxing price questions

    Cardboard is cheap, but manufacturing replica shaped foam blocks for the compact Macintosh shipping box is going to have a substantial up-front cost that is difficult to amortize when selling in small volume like 50 boxes total.  It is possible to change the design to make it cheaper, but then...

    Which compact Macintosh models would you be interested in having replica boxing for?

    Sure, that's an interesting idea, of course it wouldn't be useful as a shipping box since there would be no room for sufficient padding.  Well, unless you are fine really cheaping on out the padding.  maceffect's clear case shipping boxes definitely had an advantage by, in substantial terms, not...

    Which compact Macintosh models would you be interested in having replica boxing for?

    Kind of stepping outside of vintage Macintosh and into Apple II territory, I've been thinking about putting together box designs for the Apple II 5.25 disk drive, the later revision with the thinner insertion slot and pop-out eject. One thing I've also been wondering about is box prints that...

    Arduino SCSI device - Work in Progress

    Hacks territory there, the internal pull-ups are not low resistance like the SCSI bus terminators so technically the bus isn't "in spec" if you go that route, but I'd vouch I personally prefer that hack if it works because it also negates the need for transceivers with high-current sinking...

    Reverse Engineering the Macintosh SE PCB & Custom Chips for 1:1 reproduction

    Yeah, actually @Torbar, have you seen the FluxEngine?  This basically is a board that uses IBM drives and a custom floppy disk controller to be able to read/write other formats like Macintosh 400k and 800k, via flux image streaming to a powerful computer...  point in hand, it definitely should...

    Arduino SCSI device - Work in Progress

    Cool, I was thinking about this for quite a while and I should probably leave a few comments of my own... One development dynamic that's been interesting on RaSCSI and some of the related projects was a lack of foresight.  You mention focusing on storage only, and yes, always good to get...

    RaSCSI Development Thread

    At the outset, the idea sounds awesome!  Of course, as you've mentioned, there's still plenty of work to be done on the implementation.  A proper video driver interface, like used by the old PDS video expansion cards, would expose drawing commands that would be hardware accelerated, and that...

    Macintosh SE/30 Schematics (modernization effort)

    F.Y.I. @elemenoh added me as a contributor to the primary macse30mlb repository, so both the primary macse30mlb repository and my fork are up-to-date now. Primary: https://github.com/mishimasensei/macse30mlb My fork: https://github.com/quorten/macse30mlb

    RaSCSI Development Thread

    Well I was looking at this further and the RaSCSI bus transceivers are compatible, very similar to the first design of pi-parport actually.  So really all that's needed is to add a few switches/transistors to change the bus termination resistors and an external dongle to rewire the pinout on the...

    Mac SE - Single Pixel Thick Verticle Jail-lines

    Regarding schematic, I've retraced the nigh unreadable incomplete fragment of a schematic and have it here in my GitHub repository.  Pages 2 and 3 are nowhere to be found on the Internet, but at least page 1 covers everything you need to know about your circuit in question.

    Mac SE - Single Pixel Thick Verticle Jail-lines

    If you mention damaged trace on the logic board... let me put up my guess from what little I know of the Macintosh SE logic board. The BBU chip is responsible for fetching video as a 16-bit word at a time from RAM by controlling *DTACK to prevent the CPU from accessing RAM at the same time. ...

    Which compact Macintosh models would you be interested in having replica boxing for?

    Can someone find good photos of the Macintosh 512k box?  I've had trouble finding them myself, I'd assume it's basically the same as the 512ke box but without "enhanced" printed, but photos are the only way to know for sure.  Also on the poll, I'm seeing interest for 512k is higher than for 512ke.

    Replica boxing for Macintosh SE

    Exterior cardboard design of the Macintosh 128k was quite easy, all vector graphics.  Interior box designs are mostly copied from exterior ones, except for the power cord, so that will be pretty easy to finish off too.

    Replica boxing for Macintosh SE

    @CC_333 Yeah, if you still have the foam blocks, photos of them would definitely be a help!  I believe the Macintosh SE/30 used redesigned foam that was meant to be nearly universal across all models of compact Macintosh, at least for some of the pieces.  Later model Macintosh Plus and Macintosh...

    Which compact Macintosh models would you be interested in having replica boxing for?

    Okay, so some discussion about ideas of pricing I've been thinking about.  Initially I was thinking all boxes would be pretty much sold at the same price, i.e. any cardboard only approx. $15, any cardboard plus foam approx. $80.  Granted that SE/30 machines resell for a bit higher price than the...
