To: 999 (all members) From: K3H (ALBERT SCHOFIELD.) Subject: TAPE TO DISC ON THE BBC B . JETPAC is a game in two parts, JE TPAC and JET-PAC. Both are in machine c ode and both are locked. However both parts work equally well when unloc ked. If the first part is catalogued u sing *OPT1,2 then the load address is g iven as &D80. This load address is fals e. To find the true load address, catalogue the file and as soon as the first block (00) appears press ESC APE and then enter PRINT~!&3BE . The t rue load address will be given. The tr ue load address is &5C00. Load in the first part from casse tte with an unlocking utility using:- *LOAD""1900. Save it to disc using :- *SAVE JETPAC 1900+600 6000 5C00 The load address of the second pa rt is also given as &D80 and this is also false. The true load address is &2 000. 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 w ill 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 wou ld appear on the BBC/Electron. Its very simple to do and you don' t need to cough up for any commercia l software. A simple PD utility call ed Beebscreen will enable you to conv ert Archimedes sprites to BBC screens or vice versa and ChangeFSI which is a graphics utility free on Archimede s system disks enables scaling. Firstly load up ChangeFSI and sele ct Mode 1 or 0 on the Archimedes. In the ChangeFSI options change scaling s o that it fills screen, which means ticking either 320x256 or 640x256. You may also consider using the sharpe n or brighten images option for best results. Also the sharpness factor can be varied over a wide range. Drop your image onto ChangeFSI wha t ever the format (as long as its a well known one like JPEG, GIF, sprite e tc) and the conversion will commence. Even on the SA there can be a delay especially if there's a lot of sca ling involved but whatever the system i t shouldn't take too long. Sprite to sprite conversion is always quicke r 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 spr ite. If you've created a mode 1 sprite you may want to edit the palette to ma tch the BBCs as it will create an imag e using the larger Archimedes palett e although obviously only 4 such colours. Make sure the palette edi t option is ticked so you can edit i t. With beebscreen make sure the box setting displays a little BBC. Thi s 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 with out crashing out. It only seems to lik e BBC modes which can be used by the Archimedes desktop which is Modes 0 and 1. However perhaps an alternat ive art package will enable other mode s to be used but I don't have such a package. It can be surprising quick to conv ert a 24bit Jpeg image to a mode 1 scr een and the results I think are impres sive for what is a 1982 design in computers. When you think about it the BBCs 640x256 Mode 0 screen is abou t three times the resolution of the 1982 Spectrum 256x192. The spectrums attribute colour system is totally useless for actual image conversio n. I've done a conversion of the PCs Elite Plus 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 im ages converted to the BBC then send the m to me on a 3.5 disk (PC format if necessary) and I will return the s ame disk reformatted to DFS or ADFS wi th the converted images on. Don't for get to include a SSAE and if your feel ing generous perhaps a bonus blank dis k for my time. Each file is 20k so 1 8 on a 80T DFS double sided disk and 30 on ADFS (640k). If its for a Electron P3 send a preformatted 320k disk.

I suppose this wouldn't matt er if the other BBC emulator 6502em d id everything I want it to but it doesn't. 6502em's Virtual DFS does n'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 solutio n and its called Strongcache. It ena bles you to turn off the SA's cache usi ng double shift plus F1 to disable it and double shift plus F2 to re-enable it. You can do this at anytime. You st ill need Game on to emulate the origin al Archimedes Graphics chip so in eff ect you need two compatibility program s at the same time. You can get partial compatibility with just StrongCach e but changing modes will crash it. Simply boot up 65host with the cac he off and re-enable it once loaded. ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,, ReplyTo: E3M (Steve Allsopp) From: K8G (Jonathan Harston) Subject: Printer not printing '0's If Gem on your 512 board is printi ng '0's, but when printing from nativ e BBC applications doesn't, it seems the most obvious thing is that you hav e got the Printer Ignore Character s et to 48 (ie '0').
