The MIPS ‘ThinkPad’ and the unreleased Commodore HHC-4

Old Vintage Computing Research, by the incredibly knowledgeable Cameron Kaiser, is one of the best resources on the web about genuinely obscure retrocomputing, often diving quite deep in topics nobody else covers – or even can cover, considering how rare some of the hardware Kaiser covers is. I link to Old VCR all the time, and today I’ve got two more great articles by Kaiser for you.

First, we’ve got the more well-known – relatively speaking – of the two devices covered today, and that’s the MIPS ThinkPad, officially known as the IBM WorkPad z50. This was a Windows CE 2.11 device powered by a NEC VR4120 MIPS processor, running at 131 Mhz, released in 1999. Astute readers might note the WorkPad branding, which IBM also used for several rebranded Palm Pilots. Kaiser goes into his usual great detail covering this device, with tons of photos, and I couldn’t stop reading for a second. There’s so much good information in here I have no clue what to highlight, but since OSNews has OS in the name, this section makes sense to focus on:

The desktop shortcuts are pre-populated in ROM along with a whole bunch of applications. The marquee set that came on H/PC Pro machines was Microsoft Pocket Office (Pocket Word, Pocket Excel, Pocket Access and Pocket PowerPoint), Pocket Outlook (Calendar, Contacts, Inbox and Tasks) and Pocket Internet Explorer, but Microsoft also included Calculator, InkWriter (not too useful on the z50 without a touch screen), Microsoft Voice Recorder, World Clock, ActiveSync (a la Palm HotSync), PC Link (direct connect, not networked), Remote Networking, Terminal (serial port and modem), Windows Explorer and, of course, Solitaire. IBM additionally licensed and included some of bSquare’s software suite, including bFAX Pro for sending and receiving faxes with the softmodem, bPRINT for printing and bUSEFUL Backup Plus for system backups, along with a battery calibrator and a Rapid Access quick configuration tool. There is also a CMD.EXE command shell, though it too is smaller and less functional than its desktop counterpart.

Using especially these older versions of Windows CE is a wild experience, because you can clearly tell Microsoft was trying really hard to make it look and feel like ‘normal’ Windows, but as anyone who used Windows CE back then can attest, it was a rather poor imitation with a ton of weird limitations and design decisions borne from the limited hardware it was designed to run on. I absolutely adore the various incarnations of Windows CE and associated graphical shells it ran – especially the PocketPC days – but there’s no denying it always felt quite clunky.

Moving on, the second Old VCR article I’m covering today is more difficult for me to write about, since I am too young to have any experience with the 8 bit era – save for some experience with the MSX platform as a wee child – so I have no affinity for machines like the Commodore 64 and similar machines from that era. And, well, this article just so happens to be covering something called the Commodore HHC-4.

Once upon a time (and that time was Winter CES 1983), Commodore announced what was to be their one and only handheld computer, the Commodore HHC-4. It was never released and never seen again, at least not in that form. But it turns out that not only did the HHC-4 actually exist, it also wasn’t manufactured by Commodore — it was a Toshiba.

Like Superman had Clark Kent, the Commodore HHC-4 had a secret identity too: the Toshiba Pasopia Mini IHC-8000, the very first portable computer Toshiba ever made. And like Clark Kent was Superman with glasses, compare the real device to the Commodore marketing photo and you can see that it’s the very same machine modulo a plastic palette swap. Of course there’s more to the story than that.

Of course, Kaiser hunted down an IHC-8000, and details his experiences with the little handheld, calculator-like machine. It turns out it’s most likely using some unspecified in-house Toshiba architecture, running at a few hundred kHz, and it’s apparently quite sluggish. It never made it to market in Commodore livery, most likely because of its abysmal performance. The amount of work required to make this little machine more capable and competitive probably couldn’t be recouped by its intended list price, Kaiser argues.
