To: 999 (all members) From: K3H (ALBERT SCHOFIELD.) Subject: TAPE TO DISC ON THE BBC B. JETPAC is a game in two parts, JETPAC and JET-PAC. Both are in machine code and both are locked. However both parts work equally well when unlocked. If the first part is catalogued using *OPT1,2 then the load address is given as &D80. This load address is false. To find the true load address, catalogue the file and as soon as the first block (00) appears press ESCAPE and then enter PRINT~!&3BE . The true load address will be given. The true load address is &5C00. Load in the first part from cassette with an unlocking utility using:- *LOAD""1900. Save it to disc using:- *SAVE JETPAC 1900+600 6000 5C00 The load address of the second part is also given as &D80 and this is also false. The true load address is &2000. Load in the second part using an unlocking utility and using:- *LOAD""1900 . Save to disc using:- *SAVE JET-PAC 1900+3A00 5900 2000 Entering *RUN JETPAC or *JETPAC will now load and run the game. From: 4WL (Martin Wilson) Subject: Converted Screens I've converted many foreign images to the BBC in my time, mainly due to my own curiosity to how good they would appear on the BBC/Electron. Its very simple to do and you don't need to cough up for any commercial software. A simple PD utility called Beebscreen will enable you to convert Archimedes sprites to BBC screens or vice versa and ChangeFSI which is a graphics utility free on Archimedes system disks enables scaling. Firstly load up ChangeFSI and select Mode 1 or 0 on the Archimedes. In the ChangeFSI options change scaling so that it fills screen, which means ticking either 320x256 or 640x256. You may also consider using the sharpen or brighten images option for best results. Also the sharpness factor can be varied over a wide range. Drop your image onto ChangeFSI what ever the format (as long as its a well known one like JPEG, GIF, sprite etc) and the conversion will commence. Even on the SA there can be a delay especially if there's a lot of scaling involved but whatever the system it shouldn't take too long. Sprite to sprite conversion is always quicker though. If your using a 3.6/3.7 OS computer enable sprite instead of Jpeg output before you start. You can then view your image. Sometimes its clearer to move back to a decent colour mode afterwards to view your new mode 1 or mode 0 sprite. If you've created a mode 1 sprite you may want to edit the palette to match the BBCs as it will create an image using the larger Archimedes palette although obviously only 4 such colours. Make sure the palette edit option is ticked so you can edit it. With beebscreen make sure the box setting displays a little BBC. This image is quite small so you may overlook this initially. Then drop your sprite on the right mode box. I found ChangeFSI to be incapable of generating other mode screens without crashing out. It only seems to like BBC modes which can be used by the Archimedes desktop which is Modes 0 and 1. However perhaps an alternative art package will enable other modes to be used but I don't have such a package. It can be surprising quick to convert a 24bit Jpeg image to a mode 1 screen and the results I think are impressive for what is a 1982 design in computers. When you think about it the BBCs 640x256 Mode 0 screen is about three times the resolution of the 1982 Spectrum 256x192. The spectrums attribute colour system is totally useless for actual image conversion. I've done a conversion of the PCs ElitePlus title screen. Originally a MCGA 320x200 256 colour image and you may have seen some of my earlier conversions on earlier 8BS issues. Anyone who wants foreign screen images converted to the BBC then send them to me on a 3.5 disk (PC format if necessary) and I will return the same disk reformatted to DFS or ADFS with the converted images on. Don't forget to include a SSAE and if your feeling generous perhaps a bonus blank disk for my time. Each file is 20k so 18 on a 80T DFS double sided disk and 30 on ADFS (640k). If its for a Electron P3 send a preformatted 320k disk. Martin Wilson 32 Grass Royal Yeovil Somerset BA21 4JW From: 4WL (Martin Wilson) Subject: StrongArm and 65Host
Since getting a StrongArm PC I was annoyed to find that 65Host didn't work. I suppose this wouldn't matter if the other BBC emulator 6502em did everything I want it to but it doesn't. 6502em's Virtual DFS doesn't like the 8BS Messaging system and I used to rely on 65Host as the dependable Program for doing these messages. Anyway I've found a simple solution and its called Strongcache. It enables you to turn off the SA's cache using double shift plus F1 to disable it and double shift plus F2 to re-enable it. You can do this at anytime. You still need Game on to emulate the original Archimedes Graphics chip so in effect you need two compatibility programs at the same time. You can get partial compatibility with just StrongCache but changing modes will crash it. Simply boot up 65host with the cache off and re-enable it once loaded.

Check *STATUS IGNORE. Try setting *CONFIG. NOIGNORE or setting *CONFIG. IGNORE 0. You can set the ignore character without storing it in the configuration memory with *FX6. It looks as though *FX6,48 has been issued; ch is done by SAVE), END is done or a LOAD/CHAIN command. Try doing: !PAGE=0 No Bad Program message, but now press Escape. Bad program message appears.
