I think this is a computer I had. They were used for POS systems in Mobil petrol stations in Australia. They were _completely impossible_ to get into, the system is snapped into place and then fixed with blind screws in three sections.

Hey, I am getting an AS-100 with 8" Disk drives. Unfortunately it comes without disks/software, and I managed to find only 5.25" CP/M-86 disk images. Anybody here who could provide me 8" boot disks (either CP/M-86 or MS-DOS) or images of the 8" boot disks? It would be great to get the device running...

I have a Canon Computer system for sale. It comprises: 1 x Monitor Model AS-100. 1 x Tower Model AS-1350. 1 x Printer Model AS-1250. All Circa 1982-4.

It has been stored carefully and is in very good condition. I last saw it working a few years ago and had a DOS disc for it, but can''t find it now. If you contact me, I will send you pics.

Not sure what the asking price should be, but I know there are very few still around. It would be perfect for a computer museum or as props for older movies.

Let me have your offers. I can ship them from Australia. You can have someone local to come and look at them in Melbourne also.

An interesting exhibit. I would like to buy the Canon AS-100. Does anyone know what the Canon AS-100 costs?

I was a Canon Dealer from 1983 to the late 90s. The AS-100 was the first personal computer we sold. Software was limited but we has some success selling these for general accounting applications. We had our most success with the ATHENA. I ended up tossing three AS-100 in the dumpster but they were all in working order. We built a cabinet with wheels about the size of a small refrigerator which allowed us to transport the AS-100 to prospect sites. Can''t believe we did that.

@Rich Trying to contact you. See you on Linkedin, I think.

@Patrick - I actually have a copy of Canon BASIC that was used with the Canon Athena one of their early IBM compatibles. A copied it to a CD years ago so I should be able to find it.

In the US it came out with both operating systems. The Canon Basic worked with CPM/86 and the MS-DOS had GW-Basic. I wrote a magazine accounting application on the dual 8" disks in Canon Basic. CPM/86 had a bug that caused PIP (CPM copy) to corrupt files of over 64K in size. That burned me pretty badly. Switched to disk copying until they patched it.

I would really like a copy of the Canon BASIC for DOS. The CP/M-86 version would also be of interest.

I worked on one of these machines until 1983, developing commercial software to be bundled with hardware sales. This was before the advent of hard discs, so these machines were floppy-only. From memory the large dual floppy drives retailed for over NZ$10000.

Initially it came out only with CP/M-86, with a version of MSDOS being produced later. Many of the MSDOS programs were the same ones from CPM-86 with a wrapper that converted the interrupt calls from CP/M to DOS.

scusate, ma che lavoro facevano i vostri padri? negli anni 80 un computer costava parecchio. non parliamo poi di 4.

I have one of these... it''s been in storage for umpteen years and want to try to get it running and then a new home for it. Where can I get disks and a refresher on how it works?

I had one of these back in the ''80s - my parents bought me one for Christmas when I was in middle school. Mine had the color display with color printer on top and ran MS-DOS v1.25 bundled with SuperCalc and WordStar processor (man I used to have those Ctrl codes down pat!). It was my first PC and started a life-long love of computers. After a long time, it finally gave up the ghost and ended up in parts.

My father had 4 of these computers that he had bought in new in the mid 1980''s and 3 ran up to DEC 2010. Each weighed a heap but the quality both inside and out was awesome. We called Canon Australia to see if they wanted them for historic reasons and was rudely told that Canon never made computers! Unfortunately they now reside at the local tip.

The AS-100 had a graphic chip. I guess the NEC 7220 but I am not sure. It was dead slow: you could see it drawing lines starting at one end, to then progress to the other end. I ended up writing my own assembly library to do graphics on it.
