    Web server for Macintosh 512K

    wow, sorry, I meant WOW!! Well done, that is an awesome achievement. I havent been around here for a while so have only just learnt of your awesomeness today. I was truly blown away. I'm pretty sure that in past discussion about being able to do something like this on a 128k Mac using Mac OS, the idea was dumped in the "impossible" basket. Excellent work. I look forward to taking some time to read through your blog (not that I'll be able to understand all the technical bits!). Cheers,

    Battle Chess Tournament, Anyone?

    Could be possible to play modem dialup over the internet, but would need some additional (moderish) equipment. Hardware solutions along the lines of the Lantronix or MOXA ethernet modems (basically hayes modem emulator, serial to ethernet converter) could be used, but I suppose both parties would need the same brand converter to make it all work. Alternatively, perhaps TCPSER has this functionality, then just a reasonably common old windows box could be used as the go between on both ends.

    Localtalk Access from MSBASIC?

    Cheers, would appreciate it. Ahh yes, you are right, well done for spoting my deliberate mistake
  4. Were there any MSBASIC commands to access a Localtalk network on a classic 68k Mac? I'm thinking 64k ROM machines like the 128/512k Mac. If so, anyone got any examples? Cheers,
  5. Hi all, I've done a quick google but not come up with much, so I thought I'd be lazy and post here to see if anyone knew the answer. I've got a couple of Lisa 2 PSU's (both the low and high power varities) and was wondering if anyone knew of a reference that described the capacitors, their values and ratings, for the purposes of replacement. Both my PSU's went bang with lots and lots of smoke (very impressive) so I'm assuming I wont be able to read the values off the exisitng components. Also, a repair guide would be nice Cheers,
  6. Perfect! Cheers for that.
  7. Hi all, I have a "Macintosh Color Monitor" (its a 14" or so by the look) from around 1993 that I need to take apart - does anyone know where I can find a disassembly guide for such a beast? A quick google didnt do me much good so I thought I'd try a more targetted approach by posting here Cheers,
  8. Thanks to the good people at RetroNET, I now have somewhere to host some web pages. So, I have moved this bloggy type post over to there, and have even included two new amazing pictures of my LCe and Serial cable - wow. What are you waiting for?!? Heres the link - http://retro-net.org:808/~gavo/

    Gearing Up for Summer

    Seems like endurance might be the in thing this time round. Must be something in the water because I was thinking that I might try to do all of my recreational computing (media centre PC doesnt count right) on my old 128k Mac, connected to the interweb via my PC and Retro-net.org for the challenge. Should bring back some (painful) memories

    Captain Magneto - Apple III

    Hmm, interesting. Is it playable(ish) like that? Anyway, thanks for trying it out and posting - wish I still had my Apple III Cheers,

    Captain Magneto - Apple III

    There seems to be a disk image of it located at: http://adtpro.sourceforge.net/archive/WAP/html/a3games.html Cheers,
  12. Hi, I used to love Captain Magneto on my 128k Mac and recently discovered that there seems to have been a port of it to the Apple III - unfortuantely I dont have an Apple III or a Mac (on which I can run SARA the Apple III emulator) to check out the Apple III version - I'm really interested to see what the graphics were like on this platform. Did anyone here ever play it on the III? What was it like - was the game play similar to the Mac version? Anyone got any screen shots (or better yet youtube video)? Wishful thinking perhaps. Cheers,
  13. Well, the RetroBaud has now officially been retired. I had a lot of fun (after the frustration) getting it going - but even more fun BBS'ing once it was up. I also enjoyed getting me Apple IIe card going in my LC475 despite not being able to get the BBS running on it. I was a bit MIA for the last week of the RC, I had hoped to write a high scores module for the door games on the RetroBaud, but just wasnt able to do it. I have to say that I'd highly recommend the RC to anyone. Its a laugh and by entering myself, I found that I felt a little more connected to the other contestants and their challenges (there were some really good ones complimented by great blogs). The final stats for the RetroBaud were: Users Registered (including me) : 9 Number of Calls taken during the RC : 77 Number of messages posted : 31 Games: Microbandit. WGOODF takes it out with a late run, which I'd have to say was a bit of an upset as LUDDITE was clearly the most consistent player during the RC and led right until the end. WGOODF $432.50 LUDDITE $303 GAVO $248.50 URBANCAMO $55 ARFINK $46 MACMAN $28.50 COXY $7.50 One note tho WGOODF, dont be spending that cash too quick - its in NZ dollars, not pounds! Rock Paper Scissors. A hard game to score, but I decided that rankings would be based on the percentage of games won (perhaps somewhat controversially) with a minimum of 30 games needed for a player to become eligible - on that theory, LUDDITE sneaks past WGOODF by the smallest of margins to take the victory. LUDDITE 51 games won, 52 lost (49.5%) and 57 tied. WGOODF 45 games won, 46 lost (49.4%) and 39 tied. GAVO 51 games won, 68 lost (42.8%) and 51 tied. MACMAN 4 games won, 2 lost (66.6%) and 4 tied. URBANCAMO 3 games won, 5 lost (37.5%) and 2 tied. Leeches. Turned out not to be the most popular game of the series (although I like it) - at the end of the RC no one was higher than Level 1. I did in fact make it to quite a high level, but was cuzed by the game near the end and so ended up with nothing. The winner here is clearly the RetroBaud - repelling all pretenders. Anyway, this marks the absolute end of my 2009 winter warm up RC - well done to all - and see you next time. Cheers, -Gavo.
  14. Well, heres a quite bit I wrote up on my final solution - feel free to ask any questions. Whilst I would have preferred to have my Warp6 BBS running on my LC 475’s //e card, I was forced to run it on my XP workstation under the KEGS emulator due to Warp6’s incompatibility with the //e card. Essentially this is the brief run down of how I did it. Software Used in the End: KEGS 0.91 (http://kegs.sourceforge.net/) - //gs emulator TCPSER (http://www.jbrain.com/pub/linux/serial/) - Hayes compatible modem emulator for getting your old serial comms app onto the internet. Note I’m not exactly sure which version I’m running now – I had thought it was 1.0RC12 – but I’m not so sure looking at the file sizes. Warp6 BBS 2.5 – (http://mirrors.apple2.org.za/apple.cabi.net/Applications/Telcom/WARP6.BBS/) - the BBS software Warped – (http://mirrors.apple2.org.za/ground.icaen.uiowa.edu/Collections/1WSW/warped.shk) - the door games for the Warp6 BBS Ciderpress v3.0.0 – (http://ciderpress.sourceforge.net/) - All round wonderful program for Windows PC’s for messing with emulator images and .SHK files Step 1 – Get Warp6 BBS image up and running in the emulator Having decided to go with KEGS as a result of some testing of different emulators specifically around serial port support (note that in the end a lot of the issues I was experiencing could probably be put down to my cable that I resolved at the end – but I never went back and tested the other emulators) the first thing to do was to get the Warp6 BBS image up and running. I wont go into the details here because I actually already had the base Warp6 emulator image up and running from a previous play with it a few years back, but essentially if my memory serves the process is something along the lines of - Use CiderPress to make a HDV image - Use CiderPress to copy the Warp6.shk and Warped.shk to the new HDV image - Download a disk image with ProDos and shrinkit tools - Start emulator and un-shrink the archives to your HDV image and install ProDos The actual configuration of Warp6 is covered in the warp6 doco that is supplied in the archive. I’ll just go over some of the specifics here. Step 2 – Configure the Warp6 BBS doors Again, the warped.shk contains information on how to do this, however I noticed that two applications (insulter and the doorway) worked locally but not remotely. This was because Warp6 requires you to get input from users in a specific way in order to protect from crashes (which might dump you into a BASIC prompt) and to check and enforce time limits. As luck would have it the BBS doco talks about how to do this and I simply copied the Applesoft code from the “Micro bandit” game into doorway and insulter (using the wonderful applesoft line editor). I guess I had an advantage here as I had (man many many years ago) written some of the customisations in the warped.shk archive. The final thing required was to install the modem drivers specific for use with the //gs serial port (as opposed to the Apple //’s super serial card) – this again is covered in the Warp6 doco and essentially requires the copying of two files into the Warp6 BBS main directory. Step 3 – Getting the BBS online Warp6 BBS expects to see a real old style hayes compatible modem to talk to. If it see’s that (like most old school BBS packages) its happy. Fortunately for us retro guys theres some really smart guys like Jim Brain who write some really cool software like TCPSER. TCPSER is a modem emulator with a twist. It runs on your PC (or linux/mac if you are using the cross platform java version I understand) and does two things. 1. Binds to a physical serial port on your machine to allow any other serial device to be connected to that port and see what it thinks is a standard hayes compatible modem – one that sends all the right responses back to those interesting AT commands we used to love 2. Replaces the traditional “phone line” with the internet and allows access to the serial device via the internet standard telnet protocol (BTW it also allows the device attached to the serial port to initiate access to the internet via telnet to!). For example if configured (by the BBS program) for answering calls, it will accept incoming telnet connections and then send the appropriate code to the device attached to the serial port – i.e RING RING, the BBS will then likely instruct the modem to connect, at which point TCPSER sends a “CONNECT” response back to the serial port and arbitrates communication between the telnet connected TCPIP session and the serial device (normally a BBS) connected to the serial port. When the BBS hangs up, TCPSER disconnects the telnet session, or if the telnet connection is dropped, TCPSER drops the serial connection to the attached device This was one of the hard parts for me, warp6 was all ready to go (more or less) but wanted to talk to a modem out of the emulated serial port (that terminated on my PC’s real DE-9). To theory behind this is that we use two serial ports on one PC. The emulator binds to one serial port and the modem emulator binds to the other, that is both end up poking out of the back of the machine to the real world. To connect these two things together requires the use of a serial cable (just like you would do to connect a real GS to a real modem). The trick being figuring out what kind of cable to use. To begin with I had no real idea of how the emulated serial port mapped to my real serial port, and how the signals from the GS’s mini DIN related to those on my DE-9. After quite a bit of head scratching, googling and burnt fingers, I settled on the following cable and made the bold assumption that KEGS doesn’t honour the DCD signal on the PC’s real DE-9 Ultimately, the following signals are the ones I decided I needed to use: DE-9 (my PC’s connector) Pin 2 – Recevied Data Pin 3 – Transmitted Data Pin 4 – Data Terminal Ready Pin 5 – Signal Ground Pin 6 – Data Set Ready Pin 7 – Request to Send Pin 8 – Clear to Send So to get comms going between TCPSER and my emulated GS I built a cable like this: COM1 = Physical port that my modem emulator (TCPSER) bound to COM2 = Physical port that my emulated GS serial port bound to COM1 COM2 PIN2 (RCD) ----------------------- (TXD) PIN3 PIN3 (TXD) ----------------------- (RXD) PIN2 PIN4 (DTR) ----------------------- (DSR) PIN6 PIN5 (GND) ---------------------- (GND) PIN5 PIN7 (RTS) ----------------------- (CTS) PIN8 PIN8 (CTS) ----------------------- (RTS) PIN7 This cable doesn’t support DCD (PIN1 to PIN1) but it doesn’t seem like KEGS honours it anyway? I could be wrong about this, but I couldn’t get it to work and ultimately for my purposes it doesn’t need to – if someone drops carrier (disconnects the telnet session without logging off) the BBS times out after about 5 minutes and resets for the next caller – during this time no one can connect, but its not a big deal. The only other thing I did was to much sure KEGS serial port emulation was set to “Use real ports if available” – this ensures that it binds to the real COM port and doesn’t start a TCPIP virtual modem instead – the KEGS virtual modem is a similar concept to TCPSER, but built into KEGS – it worked for me, but not with Warp6, so I didn’t play with it much. You set the KEGS serial port setting by hitting F4 when the emulator is running – this brings up the KEGS config screen that will write changes back to the config.kegs file. Some screen shots: Damn, I cant paste my pictures in here - is that even possible on this board? Anyway, I guess I'll have to see if I can figure out something else - they're not too exciting anyway...[/img]
