    How much of the 128K/512K hardware has been reverse engineered?

    LOL! I hear that! On a side note, have you been able to make time to reverse any of your board layouts that we've talked about into KICAD schematic form?

    Apple II text output to servo controlled Etch A Sketch display in cursive font?

    Yep, is there a plotter driver for Apple II or C64?

    ATTO Silicon Express IV Nubus

    Dunno, was the SEII fast only? The IIfx is well and truly buried, but I may be able to get to it. Just looked, but the box wasn't where I thought it was.

    Apple II text output to servo controlled Etch A Sketch display in cursive font?

    Talking about spinning the knobs on the real thing with stepper motors here. Emulation's not the point at all. ;) Getting the stepper output data back into the Apple II to draw it onscreen would be for bonus points. Stepper moves for its drum plotter were drawn on the TTL CRT display of my...

    A Classic II/LC III laptop/book….

    Hartmut and the Tadpoles were tripping the Mac fantastic before LCD tech with its ribbon cable limitations were really a thing, no? I've got a plug-in LCD setup in a laptop I was repurposing for OrangePi playtime. I'll see if I can post some pics of that. It's the only way I can think of offhand...

    ATTO Silicon Express IV Nubus

    Cool stuff! If I had money to burn I'd do a RAID array of v6 in one of my StudioArrays on the JackHammer in my 81/110. Savvio SCA Ultras on Fast/Wide in the other one should mop the floor with Narrow SCSII SD I think? I've got a first version Silicon Express card in the IIfx. Hope to one day...

    Apple II text output to servo controlled Etch A Sketch display in cursive font?

    OK, now I'll go back where I belong. :rolleyes:

    Apple II text output to servo controlled Etch A Sketch display in cursive font?

    Ludicrous notion of the day! Sorry, I just can't help myself. Short story long, took a pic of my 1400c this morning and got to I wondering wondering how the Rudimentary Tablet next to it might work as a .TXT output display. First thought was stepper controlled by Raspberry Pi. Figured Apple II...

    Radius Two Page Display for Mac SE

    BNC->HD15 VGA connector bodge is(was?) detailed in the thread I linked in my first post. I used if for my first foray into the depths of the RTPD/SE morass. . . . definitely was documented as Pics went redirected in the forum software migration. I'll have to dig them up to post here and...

    How much of the 128K/512K hardware has been reverse engineered?

    @max1zzz Would your your ROM-inated Plus tweak work (or in any way be beneficial) for 128K-512K Rechambered project? https://68kmla.org/bb/index.php?threads/reverse-engineering-the-macintosh-plus-pcb.38414/post-430388 Have you got that one tested yet?

    Radius Two Page Display for Mac SE

    Extron Scaler suggestion is my boilerplate answer for this kind of thing. Never got the TPD dialed in, but shouldn't be a a problem. I dialed in the far more interesting SuperMac Spec/8 SI to perfection. Never did do any more RTPD/SE playtime after that first "just set it up and try it" test...

    How much of the 128K/512K hardware has been reverse engineered?

    HRMM, can't think of a good reason to bodge an all thruhole board's solder side, what with every signal available on the component side? Morning musings have me reconsidering that SIMM notion. Was a flight of fancy that wouldn't look right even if far less work. Was originally thinking a pair...

    Another dual PDS Adapter for SE/30? 🤔 (PDS only, no cache connector)

    Anytime you plug something in where it doesn't belong, power and ground pins can be randomly connected to logic signal sockets. Poof, magic smoke released.

    How much of the 128K/512K hardware has been reverse engineered?

    Yep, as noted. Was wondering about the resistor pack bodge? Factory rework of design flaw in early run boards, factory fix of faulty board or related to the wire spider infestation? Thinking one 72pin SIMM instead of DIP DRAM. Itty bitty bits of it used for 128K. Lots of room on board for a...

    How much of the 128K/512K hardware has been reverse engineered?

    HEH! Comparison here works, already spotted some stuff! Is that resistor pack bodge on VIA OEM or 512K upgrade Plus - Top Redux - Middle 128K -Bottom (w/512K Mod) Missed ASG - Same on both boards? Which Apple Chips are interchangeable?

    How much of the 128K/512K hardware has been reverse engineered?

    Here's where my prep work stands: Light Gray - off the shelf parts Yellow IC - on Plus replaces SIP resistor pack on 128K board - Resistor Network? Purple ICs - on Plus, but not on 128K Purple IC Outlines - 128K ID in black - Plus ID in Purple = which Plus versions are usable? Dark Gray ICs...

    A Classic II/LC III laptop/book….

    The Mac's case tooling was well into development (Twiggy Mac) by the time the Hartmut connection was made and Snow White slowly came into the picture. The Mac was far behind schedule and an untextured prototype TwiggyMac front bezel was was savagely mauled with a router for Sony 3.5" FDD test...

    Very nice! I thought the LCD was going to be hinged at the front edge per the Black version pic?

    USB3 Thumb Drive to IDE Converter for Q630 thru 6500/TAM

    Was wondering if RPi or the like could push USB3 in and out of the rudimentary IDE interface of this series. DuckGo'd for available hardware and found this one that might be ready to roll? https://www.amazon.com/Converter-External-Universal-Function-Software/dp/B00EHDTRJ6 No Driver needed...

    Another dual PDS Adapter for SE/30? 🤔 (PDS only, no cache connector)

    I was curious if you'd ever seen any kind of PDS splitter for the SE/30. TwinSlot for the IIsi is the only classic era example of a similar approach to expansion that I can think of offhand. Given very high costs of PCB development/production until about a decade ago, I'm not much surprised...
