S > SORD  > M23 Mark III   

M23 Mark III

The Sord M23 Mark III was available with 12" green monitor or a 14" color monitor.

Despite the M23 featured a cartridge port, all of its important software came on floppies, including the ground-breaking PIPS-III and several BASIC compiler variants developed by Sord and running on their own OS. A lot of good business software and games were written with these.

There were later Mark systems released, including a Mark I with the world's first 3.5 inch floppies deployed, and the Mark V with eight inch drives -- the Mark III had 5.25'' floppies. There was also the Mark X with a 10MB hard drive.

Around 1983 or so the "M23EX" was released - this was basically an M23 with the mk41 drives (5.25" DSHD) housed in an M68 case (more PC-style with separate keyboard and floppies in the main case). It was a low cost option contemporary with the more expensive and better spec'd M68.

Graphics required an upgrade - from memory it was a chip, and also an upgrade from "FDOS" to "GDOS" (the graphics DOS). Graphics on this and the M68 were operated in a weird way from CBASIC or BASIC-II (a structured BASIC) - you put it into graphics mode and then issued specially formatted PRINT commands to access graphics - for example:

20 GRAPH 1
... other code ....
50 GRAPH 0

I used a Sord for several years for work. The PIPS_III spreadsheet would do something in one operation that Excel still won''t - Sort and Sub total in one operation.
I think the spreadsheet was ahead of its time.
My boss bought it in Singapore where we had business interests.
Eight years ago when moving and downsizing I reluctantly gave away two Sord models - one with 5.25 and the other an 8 inch disc and all the manual etc.
There never were any good old days but I think nostalically about my Sord my first computer.

The price in Italy was Lire 4,900,000 + IVA (14$?) in 1982 (found in an old computer magazine ad), about 5 months of salary of an employee at the time.

I remember writing all this software for an Insurance Agent I knew, who had one of these Sord M23''s. Can''t remember which variant it was now. Anyway, he ran his agent business on this machine with the apps I wrote for him.
