It shipped with 4 kilobytes of RAM and 4 kilobytes of ROM (including MS BASIC). Hachette, which was responsible for documentation and software, asked genius artist <a href=\"https:\/\/en.wikipedia.org\/wiki\/Jean_Giraud\" target=\"_blank\" rel=\"noopener\">M\u0153bius<\/a> (Jean Giraud) to draw illustrations:<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-4514\" src=\"https:\/\/www.quantum-bits.org\/wp-content\/uploads\/2022\/10\/alice-basic-moebius.jpg\" alt=\"\" width=\"750\" height=\"619\"><\/p>\n<p>To be blunt, nowadays, M\u0153bius&#8217; artwork and the funky red look are the major drivers for collecting Alice computers. But, at the time, this was clearly not enough to buy one. The Alice was marketed as a <a href=\"https:\/\/www.quantum-bits.org\/?p=2941\" target=\"_blank\" rel=\"noopener\">Sinclair ZX-81<\/a> challenger, when &#8230; the ZX-81 itself was considered outdated and was already replaced by the much more capable <a href=\"https:\/\/www.quantum-bits.org\/?p=3007\" target=\"_blank\" rel=\"noopener\">Sinclair ZX Spectrum<\/a>. <strong>Needless to say that the Alice 4K wasn&#8217;t a huge success<\/strong>.<\/p>\n<p>One year later, in <strong>1984<\/strong>, Matra launched the <strong>Alice 32<\/strong>. It looked almost identical as the old Alice, apart &#8230;<\/p>\n<ul>\n<li>from the &#8220;Alice&#8221; logo, which changed from a sliver color to a white color<\/li>\n<li>from the front sticker, which came with a protective plastic cover with some kind of greenish hue<\/li>\n<li>from a change in the serial number (sticker on the bottom)<\/li>\n<li>from a change on the contacts of the expansion connector<\/li>\n<\/ul>\n<p>There were a few upgrades in terms of technical characteristics:<\/p>\n<ul>\n<li>The video chip was changed, from a <a title=\"Motorola 6847\" href=\"https:\/\/en.wikipedia.org\/wiki\/Motorola_6847\" target=\"_blank\" rel=\"noopener\">Motorola 6847<\/a> video generator to a <a class=\"mw-redirect\" title=\"\" href=\"https:\/\/en.wikipedia.org\/wiki\/Thomson_SA\">SGS-Thomson Microelectronics<\/a> <a title=\"Thomson EF9345\" href=\"https:\/\/en.wikipedia.org\/wiki\/Thomson_EF9345\" target=\"_blank\" rel=\"noopener\">EF9345<\/a> video chip<\/li>\n<li>The main RAM was bumped to 8 kilobytes<\/li>\n<li>8 kilobytes of dedicated video RAM were added<\/li>\n<li>The ROM was expanded to16 kilobytes (incorporating also an assembler)<\/li>\n<\/ul>\n<p>The Alice 32 name comes from 8 kB RAM + 8 kB vRAM + 16 kB ROM = 32. Yes, it is stupid marketing and this is misleading. It was sold around 1100F (approx. 168\u20ac at the time, 326\u20ac today) when bundled with a red datacorder unit, a set of software, manuals, cables, all packed within a red plastic suitcase:<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-4516\" src=\"https:\/\/www.quantum-bits.org\/wp-content\/uploads\/2022\/10\/matra-alice-32-suitecase.png\" alt=\"\" width=\"400\" height=\"424\"><\/p>\n<p>With its red plastic casing, the Alice 32 was more considered an expansive toy rather than the educative computer it was designed to be. Needless to say that the market response was less than lukewarm: <strong>it bombed<\/strong>.<\/p>\n<p>In <strong>1985<\/strong>, Matra released the <strong>Alice 90<\/strong> as an upgrade from the Alice 32. It featured 32 kilobytes of RAM, an oddly-shaped red casing and a full-sized mechanical keyboard. I guess it should have been called Alice 56, but somebody at the marketing department must have thought that Alice 90 sounded cooler, even though it is probably meaningless. Who knows ? Its video cable included video-in, so the EF9345 graphics could do video overlay. Which was nice, but software for video overlay came too late. It was planned to be used on a French TV show &#8230; that never aired. Unlike the Amiga <a href=\"https:\/\/en.wikipedia.org\/wiki\/Genlock\" target=\"_blank\" rel=\"noopener\">Genlock<\/a> features which were a major hit, I doubt that the video overlay capabilities of the Alice 90 were ever professionally used&#8230;<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-4520\" src=\"https:\/\/www.quantum-bits.org\/wp-content\/uploads\/2022\/10\/matra-alice90.png\" alt=\"\" width=\"650\" height=\"392\"><\/p>\n<p>Bundled with with manuals, cables, the red datacorder, a few cassettes and a red suitcase, this 1MHz 8-bit dinosaur-like computer was sold for around 1600F (244 \u20ac at the time, 449 \u20ac today) at a time when 8-bit computers like the Amstrad CPC6128 were massively better, and when 16-bit computers (Atari ST, Amiga, &#8230;) were entering the market. <strong>It failed miserably<\/strong>.<\/p>\n<p>In the beginning of the 80&#8217;s, I was avidly reading <a href=\"https:\/\/en.wikipedia.org\/wiki\/Hebdogiciel\" target=\"_blank\" rel=\"noopener\">Hebdogiciel<\/a> computer magazine.

The Alice community has done an <strong>incredible<\/strong> job <a href=\"http:\/\/alice32.free.fr\/programmes\/_html\/index.html\" target=\"_blank\" rel=\"noopener\">collecting and preserving these software<\/a>. All in all, <a href=\"https:\/\/alice.system-cfg.com\/software.php\" target=\"_blank\" rel=\"noopener\">less than a hundred<\/a> titles were published (around 60). On top of that, apart for a few titles like <a href=\"http:\/\/alice32.free.fr\/programmes\/crocky\/index.html\" target=\"_blank\" rel=\"noopener\">Crocky<\/a> or <a href=\"http:\/\/alice32.free.fr\/programmes\/galaxion\/index.html\" target=\"_blank\" rel=\"noopener\">Galaxion<\/a>, I must say that they were seriously &#8230; <strong>lacking fun<\/strong>.<\/p>\n<p>These preserved software are often using the <strong>K7<\/strong> package format, that can be directly used by the <strong>DCAlice<\/strong> emulator. To load these packaged software on actual hardware (from a cassette tape player), the community published <a href=\"http:\/\/alice32.free.fr\/emulateur\/prog\/alk72wav-v1.0.zip\" target=\"_blank\" rel=\"noopener\">alk72wav<\/a>. This Windows-only tool <strong>converts<\/strong> <strong>K7<\/strong> packages <strong>into<\/strong> <strong>.wav<\/strong> sound files than can be played back. Of course, the community also published <a href=\"http:\/\/alice32.free.fr\/emulateur\/prog\/alwav2k7-v1.0.zip\" target=\"_blank\" rel=\"noopener\">alwav2k7<\/a>, that convert sounds from tapes into K7 packages.&nbsp;<\/p>\n<p>For the fun of it, I installed <strong>alk72wav<\/strong> into my Windows XP <strong>Virtual<\/strong> <strong>Machine.&nbsp;<\/strong>I settled for <strong>Crocky<\/strong>, since I already downloaded the K7 package.

Sure, it is not a powerful machine. Yes, it was badly marketed and badly priced. Indeed, it was released way too late when compared to the other 8-bit computers of the time (Amstrad, MSX, Commodore 64, &#8230;). And there were no possible competition with the 16-bit ones (Atari ST, Amiga, &#8230;) that conquered the market in the end. <strong>But, still, it is a decent, nice and simple little device.<\/strong><\/p>\n<p>Anyways, there are still a few things I would like to do:<\/p>\n<ul>\n<li><strong>Recaping<\/strong> : for my part, it is still an unresolved dilemma. Should I replace the capacitors ? It is a good thing to prevent any leakage and protect the PCB. But &#8230; they do look very good, I must say. After 40 years, it means that they were most certainly very high quality at the time. Would nowadays capacitors be that good ? I am still struggling to answer that question&#8230;<\/li>\n<li><strong>Sunbrighting<\/strong>: the keys are a very slightly yellowed and sunbrighting may help. Unfortunately, Autumn is (somewhat) here, so I may have to wait until the sun shines enough !<\/li>\n<li><strong>Video overlay<\/strong>: I&#8217;d really like to try video overlay functionalities of the Alice 90, but I have yet to figure out how to setup a proper test for that.<\/li>\n<li><strong>Playing with the assembler<\/strong>: I don&#8217;t know much about the 6803, but I&#8217;d like to give it a try for the fun of it !<\/li>\n<\/ul>\n<p>What will be the <strong>next<\/strong> <strong>vintage<\/strong> <strong>computer<\/strong> to work on ?
