On today's SMCC, we have a HeadStart Explorer all in one PC. This inexpensive "starter" home computer came with everything you need to get your family computing in no time, including a built in GUI right in ROM.

To address the confusion, Cody is my middle name and what I typically go by. Other things are William (my first name) just out of necessity :D. It is nice to see everything arrived somewhat safely. The monitor did not have a crack at the top when I shipped it so that must have been a shipment issue. I apologize for that. Shipping CRTs is difficult. The capture card is 720 so hopefully it might still be useful. I am looking forward to the new life you will give the explorer. The hard disk never worked while I had it and the interface is not quite IDE from what I remember. I am interested in how you will address that in the future. Perhaps it is just a different pinout that could be modded? Who knows. Thanks again for the great content!

You made me remember a thing my father told me. Way before polystyrene foam and chips to put on packages were widely used (although bubble wrap was common) they used a very simple biodegradable product: popcorn: yes popcorn made with hot air without oil. sometimes inside plastic bags Sometimes just dropped inside the box until it filled all empty spaces. Until this day I ask myself why we didn't keep doing that.

Very Cool! Vendex was a Long Island based technology marketing firm.. They started their HeadStart line in the mid 1980s. The first ones they sold were a conventional type PC compatible marketed through department stores like Dillards. Their all in ones came out in 1989 with the push for the fall Christmas season. The marketing ploy was the "Ease of an Apple, Compatible with IBM". IBM compatible out of the box but could have an Apple card installed. Vendex was sold in the spring of 1989 to Philips. In the US it was even marketed by Philips as a Magnavox HeadStart Explorer with a companion Magnavox monitor. Again the aim was the entry, home market. HeadStarts were really pushed at Montgomery Wards and other department stores. The prices started at about $500 and could be customized up to the mid-2K range. There were available accessories to include a stand to set the monitor over the main computer. The idea was you could use it on standard size student desk and fold the keyboard up when not in use. Very much designed for a dorm room.

"Percussive maintenance" ehehehe. My first job was with Brazilian TRS-80 Model I clones. One was called Dismac D-8000. I found one that was failing the turn-on memory test. I called my friend (that had got me the job), and he held the CPU 30cm (about a foot) over the table and dropped it (the case was made of metal, not plastic as the TRS-80). I was completely stunned. He said: "Try again" and the memory test worked. Thanks, Adrian to bring me back fond memories.

But the interesting part is that the Video Genie was a TRS-80 Model 1 clone so the Colour Genie is basically a colour TRS-80 Model 1 derivative, making it totally different from Tandy's own Coco, Colour TRS-80, which was a 6809 machine with a totally different architecture. So now I really want you to get hold of a Colour Genie!

In Britain and some of the commonwealth in the late 80's and into the 90's we had computers with a ROM OS that actually was rather popular in the education market with the ARM based Acorn A series machines (originally badged Archimedes). Naturally they were excellent for the education market as there was no way of damaging the OS and it meant that not having a hard drive was not a big issue. Bootup took seconds and they were very reliable. They even ended up being used for controlling BBC TV playout. Available in either "keyboard computer" or desktop variants, including the unique Risc PC, with stackable sections. Also interesting was that some or all of the "keyboard computer" models had just one PCB inside, with even the PSU on the main PCB and also gave birth to the first SOC.

The CRT is VGA only, no super-VGA stuff. While the VGA has three modes (350-line mode, 400-line mode and 480-line mode), all of these modes used exactly the same horizontal 31.5kHz timing. That explains why you don't have the issue of the picture moving around horizontally when you switch modes, so you don't need user-accessible horizontal image controls.

Adrian, you can run multiple ISA cards off one slot, you just need a riser or expander card. What I mean is, electrically, the cards are all just in parallel, every signal connected to the same pins in each socket. You could even perhaps make an expander card. Our chums at sponsored-by PCB factory would do it for you! You could even have a finger-connector then use ribbon cable rather than PCB, to make it more flexible. Digging about inside you might find the space. ISA was a pretty slow bus, noise probably won't be a problem. Then you wouldn't have to choose! And god knows there must be room inside that gigantic case, what the hell else could even be in there? Especially if you take the hard drive out.

So I had one of these back when they came out in the late 80's/early 90's - well still do have, albeit it is now in pieces. There was a stand that came with it that fit over the computer and held the monitor - hence all the "wasted space". Also the card slot next to the ISA slot was intended for a memory expansion module that never materialized - I spent hours pouring through Computer Shopper hoping that I'd find one when I was younger. I have a few pictures if I can figure out how to get them to you of the stand.

In the mid-90s, as a kid of 12 ages, I believed QBasic was the "Mother" of all other programs, including Windows because it was the only program the computer had installed on which can be used to make other programs. So I gave it a try and learned Basic by trial and error. A half year later, I tried to figure out how Windows is made (I still believed QBasic is the only existing programming language) and started.... The result was an DOS-GUI like this, with its own unique ugly user experience: Its default theme was about farts and poop turds coming out of rosy cheeks xD. I made a few basic features and utilities for it (customizable themes, screensavers, fonts, drawing tool, calendar, calculator, word processor, a few simple games, file browser etc.). I remember I was chewing on the word processor which was the final enemy. The final result fit on a single 3,5" disk. You had one disk with the "OS" and another one for your data. Hard drives support was missing because my computer didn't have one. Instead the computer had two floppy drives. My grandpa actually used that GUI on his old 286 DOS computer. It ran OK until the computer became broken. Unfortunately, the software itself is lost, because my dad never allowed me to program, because in his eyes I was a hacker, and destroyed my disks including the backup ones after he drunk too much. Only some of the themes and fonts survived. :(

I can't find anything on the exact graphics chip in this machine, but considering this above-standard hi-res mode, I pretty much assume that this could be an ATI or Paradise CGA clone like the Commodore PC10/PC20 (-II ATI, -III Paradise) or Amstrad PC1512 (Paradise) used. This additionally supports Plantronics Colorplus modes, which provide 320x200 16 color and Hi-Res 4-Color that CGA did not have. Unfortunately, not compatible to Tandy or EGA graphics, there was a driver for GEM, Planet X3 was the first and long time only game to support this and now, there is also a driver for Sierra Gen.1 SCI games. I found a page that states the pinout of the mouse, showing an X1/X2 and Y1/Y2, which points to quadrature pulses like used for the Amiga or Atari mouse. So it could be that this thing can be driven using an adapter cable with an Amiga mouse or my project USB RetroARDUInput (introduction video to come soon, and I would be glad to send one of these to you for an upcoming mail call, just dropped you a message)

I wonder if that's how a bus mouse works? I actually never looked into it. I'll need to open this up to try to fix the hard drive, so I can look more likely at the video chip at that time. I'm not sure anyone has torn one of these down yet. :-)

@@adriansdigitalbasement2 I have googled Busmouse and it could well be one, except for the pinout that I found for the Explorer is totally different than for a Busmouse on the same connector. But the concept is the same as for Amiga and Atari, 2 Bit Gray Code (Quadrature code). They actually pass on the signals from the encoder wheel directly, which define speed and direction. The encoder wheels have two light barriers side by side which are either open or covered in the sequence 00-01-11-10 in one direction or 00-10-11-01 in the other direction. Buttons are direct pins with pull to ground on press. So it could likely be that, with a proper adapter cable, Busmouse, Explorer mouse, Atari and Amiga mouse (also different pinouts) and projects like the MouSTer or my RetroARDUInput are interchangable.

be careful with older hard drives, not all of them park the head automatically on power off. In that case, the head may crash of you just turn off the power while the computer is running. The normal procedure for that type of drives is to use a utility that sends the appropiate shutdown command to the drive. I do not know dough, if your drive needs that. It will be interesting to "explore" the explorer some more. ---> see what i did there? 😁

I think Cathode Ray Dude's computer didn't have a hard drive fitted to it, and I think he said the hard drive was not easy to find. Maybe there's just a loose connection between your hard drive and the computer, as well as the drive being old and probably very tired.

It probably ripped off Amiga OS! This thing came out pretty late, all things considered. As for projects, I just try to stay organized and then pick one and work on it. I'll be able to make videos forever at this point!

If I were making an educational computer back then, it'd be some Z80 with 64K RAM and some off-the-shelf video chip. I certainly wouldn't clone the IBM PC, the most expensive, and most useless, educational computer around. Maybe Apple ][ would be an idea, since there was already stuff out for that, but Apple would likely sue you, not worth the bother trying to reverse-engineer their ROM. So I'd prob go for a simple Z80 and just include a bit of token educational stuff. If I were making an "educational" computer... to "help me with my homework", but really the kid's just gonna play games on it all day, I'd maybe do an MSX. They were available to license and had loads of software, nice chipset, you could surely knock up a few token adding-up games. Last thing I'd do is IBM PC though. All that cost, for useless ugly graphics and a chunky slow CPU, crappy ports of games, just... what's the point? Before you disagree, remember you're stuck in CGA-era PCs and the prices they sold for. Long before the era of the cheap clone with trimmed to the bone prices.
