I never understood why Amstrad didn't include that by default it the hardware was able to do it?. <br /><br />It's like having a 2TB Hard disk, and by default it shows 1TB, if you run a special command, then you can access the full 2TB :D bleuge*https://www.blogger.com/profile/10680908319620224638noreply@blogger.comtag:blogger.com,1999:blog-6993165553021868648.post-71426076735143908282016-01-10T01:17:29.465-05:002016-01-10T01:17:29.465-05:00@Great Hierophant: I don't think that bleuge* ...@Great Hierophant: I don't think that bleuge* referred to the PC1512 since he mentioned the display ECD200 command. I was also quite surprised that after having run the command automatically for the GEM GUI, LSL1 would suddenly look much more colorful. You could also set this mode with the dip switches, but then there was no full CGA compatibility for booter games.<br />I am surprised that CompuShow supports the PC1512, but for an image viewer software it's probably worth it. I suppose it's more work to support this in a game.<br /><br />I don't know what's up with the wrong colors. With the PC1640 programs detected EGA fine. Programs using Borland's BGI correctly used the 640x200x16 mode, and most games obviously didn't use 640x350. There were some programs which tried 640x350 which lead to an unreadable display.<br />How do other programs behave with the IBM EGA?<br />I don't get exactly what happens when you force or not force an EGA mode. I could imagine that the program has a bug so it tries to set the palette in 640x200x16 in the same way as in 640x350x16 which wouldn't work.idspispopdhttps://www.blogger.com/profile/04869350823378550040noreply@blogger.comtag:blogger.com,1999:blog-6993165553021868648.post-19086927592224960852016-01-09T08:45:34.431-05:002016-01-09T08:45:34.431-05:00Your blog always puts a smile on my face. cshow r...Your blog always puts a smile on my face. cshow really was the swiss army knife of viewers, but I have some fond memories of the CL GD VLB cards too. Somehow I got my hands on some 1" thick technical books on those cards. I'm sure I have those somewhere. I managed to use Linux Slackware (pre Red Hat) and setup custom timings on the CL. Somehow pushed 1600x1200 on a 14" SVGA CRT back then. Higher than the claimed max for both the monitor and the card. Dot pitch was useless, but man was it neat.Anonymoushttps://www.blogger.com/profile/14807781348626672979noreply@blogger.comtag:blogger.com,1999:blog-6993165553021868648.post-43507231282238757592016-01-08T19:32:10.751-05:002016-01-08T19:32:10.751-05:00I should mention that CompuShow does support the A...I should mention that CompuShow does support the Amstrad PC1512 640x200x16 mode, so you can probably display 320x200x16 and 640x200x16 pictures with it. The 640x200x16 mode is a special enhanced CGA mode, but very little software supported it. I cannot tell for sure because I do not own a PC1512, they really aren't available on my side of the great pond. <br /><br />idspispopd, there may be some relationship between the palette entries CompuShow would like to display and what it is actually displaying, I think it is highly likely that these problems would not appear with a real 350-line monitor.

(There was a Paradise EGA chipset on the mainboard.)<br />EGA modes are 320x200x16, 640x200x16 and 640x350x16.<br />We had a PC1640 with the CD monitor (basically a CGA monitor).<br />With that monitor you could use 320x200 and 640x200 but not 640x350.<br /><br />EGA has 6 TTL lines compared to the 4 CGA has. This way it can select from a palette of 64 colors. But this only works in 640x350. In the lower resolutions it is restricted to the 16 CGA colors for compatibility reasons. Maybe this is the reason for the color problems on the IBM PC with the 200-line monitor?

But then someday i discovered that if i run at commandline, > display EGA (i can't recall exactly, maybe i typed more options...) then suddenly the games displayed EGA 16 colours. It was amazing. As far i can remember this was a 320x200x16 mode<br />Unfortunatley i don't have my old Amstrad here to test...<br /><br />regards!bleuge*https://www.blogger.com/profile/10680908319620224638noreply@blogger.com
