Got around to upgrading my DEC Pro 380 (an incompatible desktop PDP-11) with an MFM emulator and a full 1MB of memory. It runs PRO/VENIX, the only official Unix option. It's going to be a lot of fun hacking on this thing in the future. Pictures and guts in the blog entry...

This was a huge pain. The 1MB unit doesn't seem to be upgradeable with the Atari 4MB card; perhaps a third party one? I got it in there but I had to cut the metal shield which was its own adventure. https://oldvcr.blogspot.com/2025/01/refurb-weekend-atari-stacy.html

Wanted to talk about my recent Stacy upgrade semi-debacle, but the ST Forum says I don't have sufficient permissions to post there? (The other Atari forums look okay.)

I finally got around to refurbishing my troublesome IIci with a MacIvory III, the last and most powerful of the NuBus Lisp coprocessor boards running Genera, and a direct descendant of the MIT Lisp machines. This machine all told has cost me over $6000, first the $4500 purchase price - which...

Many folks may be unaware of the oddball WorkSlate from Convergent Technologies, a 1983 slab portable with a 6800-family CPU where everything is a spreadsheet. It was a commercial failure after seven months and Convergent took millions of dollars in losses on it. A printer/plotter (with the...

I was able to make, and then hack, disk images for the Canon Cat, Jef Raskin's 1987 "work processor." Despite what Canon sold it as, though, Raskin always intended it as a fully working general purpose computer. It has a 68000 CPU and its ROMs are primarily programmed in tForth, a...

The WiiN-PAD (yes, really, they spell it like that) is the first PowerPC Windows CE system I've ever found. Does anyone know of any others? This is a little handheld slate intended for medical applications with Windows CE 2.12. It has internal flash and a camera for reading barcodes, and it can...

This is something I've literally tinkered with for over twenty years, so it's time to clean it up and open source it, along with the Incredible KIMplement 1.0, its original demonstration application (a KIM-1 emulator that runs on a Commodore 64). 6o6 "6502-on-6502" presents a full NMOS 6502 to...

This is a bit of a grab bag, but some of you will remember my DVT prototype Macintosh Portable (happily running with Androda's RAM card). It was formerly used by an Apple district manager and I wanted to back it up and then start digging into what was there. Well, that's all done, and it...

No, not the client - actual NetWare. It looks like this: This is NetWare 4.11 running on a Power Mac 6100, though the project (codenamed Cyberpunk) was actually intended for the Apple Network Server. Incredibly, there is still a Forth word "setenv-netware" in the production ANS ROM. Cyberpunk...

The Apple Network Server's implementation of AIX had a secret weapon, and that was a full Unix-side implementation of AppleTalk, Apple events and the Program-to-Program Communications Toolbox (PPC Toolbox). Apple published demonstration applications where Mac clients could offload their...

I managed to land an unopened copy of the Cyberdog Programmer's Kit book. This included a full CD-ROM with Cyberdog 1.0, the Cyberdog SDK, and many interesting videos and documents. With tweaks it all builds in CodeWarrior Gold 9 and generates real, working Cyberdog/OpenDoc parts. So here they...

This is about the AtariLab, but here it's being run on a Commodore 64 using the Hayden software (getting the thermistor recalibrated was a pain!). Also includes a look at the Universal Laboratory Interface, its successor. Warning: contains math and abuse of electronics...

MacLynx is an update to the original 1997 MacLynx that provides a native Lynx text browser port on A/UX 3.x, System 7.x and higher, with Mac quality-of-life improvements and support for TLS 1.3 through Crypto Ancienne (either self-hosted or on another system). Changes in this release: -...

If you have the red ROM for the AITB (Set Top Box/STB), the one that displays on the composite outputs, you can actually hack the unusual form of System 7.1 it includes in ROM. It works great with a BMOW 2MB ROM-inator and a SIMM programmer...

The Commodore 64 ComputerEyes video digitizer can't display live(ish, it's slow scan) video during capture because the VIC-II DMA interferes. So .... let's put the 128's VDC high-resolution chip into low resolution and use that. And then make the capture rate 25% faster...

Got Androda's new RAM card and it works great in my DVT prototype Portable (8MB). Decided to post some pictures - including of the early System 7.0 demo presentation it had on its hard disk from the prior owner. https://oldvcr.blogspot.com/2023/06/new-ram-card-prototype-mac-portable.html

The KIM-1 was the first 6502-based computer, with 1K (actually 1152 bytes) of RAM and a 1MHz clock speed. It has serial routines, but the DECtalk Express it's connected to as a speech synthesizer (using Perfect Paul, which famously was the basis for Professor Hawking's voice) only talks at...

In addition to an AmigaOS with ixemul port, you can now use carl, a mini-curl clone, as an MPW tool for TLS 1.3 from classic Mac OS. It compiles with MrC. More here: https://oldvcr.blogspot.com/2023/04/crypto-ancienne-22-now-supported-on.html Next step is to make an inetd clone that can run MPW...

A new release of the Incredible KIMplement, a Commodore KIM-1 emulator that runs on your Commodore 64. The KIM-1 is a 1976 single board computer with a 1MHz MOS 6502 CPU, 1K of RAM, six hex LEDs and a keypad, and was one of the first complete systems you could assemble for just a few hundred...
