Alex, I read your message of Oct. 21: >My little boy's Amiga 1200 has 2M memory, but some games now demand more. >The only supplier I've found has a 4M card, but that's incredibly >expensive. Is there a supplier that might offer a 2M addition at more >manageable cost? I…
Nope.. transferring from an A500 to an A500+ should be painless.. I used an HD+ on an A500 for years, if your A500 is already running WB2.04 then you won't notice any difference at all that's what A500+'s were shipped with in the UK.. if your moving from 1.3 to…
The CK722 and the 2N104 were the first transistors that could be bought at a price of less than $10, so their appearance was quite a breakthrough. The CK722 was NPN and the 2N104 PNP, so you could try one of each. Economical power transistors started arriving a year later.…
When IBM chose a processor, they had the option of the 68000, but intel offered them a better deal ( a couple of dollars per chip probably ). The people who worked on the original pc have stated that they regretted their choice. Phill
With the amount of noise on a mains cable, a bit of phase error isn't going to make much of a difference. The mains isn't anyway near a perfect waveform. Phill
That definitive article explaining transistors for the non-engineer types was written by none other than Amiga-Forum member, Jim Butterfield – and quite an article it was, too. Popular Electronics had been around for a while before that, though. I cleared out an almost complete set from about 1952-1985 or so…
Bart, pisano! You have an ELFII? You know what this means? We can ask CIS to start up an 1802 forum for us. Actually mine is packed in a box but I have kept all the parts through moves to and from Germany over the years and have meant to…
Ooooh! Gosh Betty, I didn't even know PE went back that far, I first became aware of the transistor through a project in the ARRL bible. The RCA CK721 or CK722 as I recall (amazing, I remembered). Couldn't build it, xistors cost nearly $100 each back then and had a…
Hi Wrong answer: it is too damned bad that IBM picked the most crippled mpu out there to base their Personal Computer on instead of the 1802 or at least the 6800. Today's desktop computer would almost certainly be a generation further ahead of where it is today. In other…
#a500 to a500+
Message #217137
are there any implications of trouble by transfering my GVP hd+ to an a500+ from my 2.04 amiga??? shaun
FWIW, it has to be damn close – or the national grid wouldn't work. As I recall there is a sort of "genlock" they use to allow multiple generating stations to feed the grid. The consequences of a little bit of phase error are quite frightening. Steve Brightman Daring to…
Asha, I had not "seen" him here in a while, was wondering if he kept his account here active after moving west. On GEnie he even has his own "section", an area where people can post questions to him in an open forum. Seems like someone _always_ come up w/…
GVP series II HD help?
Message #217108
Hi all, I`m hoping for some help with my GVP hard disk power supply that has gone dead. I don`t have the circuit diagrams to check it out but the voltage seems to go missing near the imput rather than further on into the circuit. Does anyone know if this…
I forgot to mention that the official HP name for this machine is "paper feed repair kit". Later. DickOUX
Of course, I read it, Jim. I even understood part of it. —Betty
Tom, Do you still use your ELF II ever? Mine is right here beside me as I type this. But my terminal board no longer works, and I haven't used it since 1986 when I bought my first Amiga. Actually, I bought the Amiga because I was upgrading my ELF…
Umm .. did you get around to reading that article about how transistors work yet, Betty? 🙂 Jim
Todd, Denny Atkin also has, or had an account here (CIS) as: 74431,421. Asha @}–,–`–
Dick, Good advice! I shall take it. Thanks, Pete
Hi David, The best of my recollection, you need to add 512K to the expansion card bay to see 1MB of chip RAM from the 1MB Agnus. I don't believe the 512K sockets were every implemented. Hnka Videology, Inc Where you always get P.O.M.P. and Service under all circumstances
Chuck, Denny can be reached over on the Amiga "Starship" forum on GEnie. (or you could send him an e-mail – DENNYA@Genie,com) If I can, I'll try & forward you problem to him. One way or another, I am sure he will here of your troubles 🙂 -|- T.P.K. -…
Pete, >If I come across anything for the Amiga, I'll let you know. Great! Thanks. When folks were initially discussing the need for this buffing machine on-line, it was assumed that some enterprising Amigan progammer would find a way to duplicate the DOS prog – but I have not seen…
Chuck, No…I don't think there's a doc here, but yes…Denny checks in now and then. Don
>Have you tried starting > HDToolbox DEVICE=ExpXDS.device from a CLI and >then clicking on "Read configuration from device" in the Change Drive Type >/Define New Drive menu? >This should give you the number of tracks/sectors etc. of the drive. Well, I tried it, and it didn't work. Also, it seems…
I have a copy of the Popular Electronics issue that first explained how transistors work. —Betty
Don, Thanks for the quick response. I did just that today before firing up my system. It is awfully crowded in there with the vxl 68040 w/ 2m 32bit ram, Flicker free video, DKB megachip all under the drive bays. They are insulated with some index card weight stock to…
Dick, Thanks for the info. I am in Belgium, in fact. I think my machine dates from the period you quote, but I have not had the sheet feeding problem so far. If I come across anything for the Amiga, I'll let you know. Cheers, Pete
Thanks. Will do that tomorrow
Pete, From whence do you hail? If you live in Canada, then (if you need the kit) you should have gotten it. I could find nothing regarding any other country. Not a clue. HP says they sent out kits to owners of: HP Deskjet Deskwriter 520 Deskjet 550C (mine) 560C…
1802, never heard of that one, it's a good job IBM didn't pick that one to put in the pc 😉 Phill
#A2500Woes
Message #216792
chuck, Try cleaning out the interior of you A2500 and re-seating all the chips, boards and connectors. Yes, the blinking is significant, but unfortunately I don't have the list of what they mean available. Don
Phillip I don't have the A1000 anymore, and don't even know the serial number. It was probably low though, and I wish I hadn't sold it to that young airman at Rhein Main AB to play games on. Hey, talk about antiques, how about this one: I have a copy…
Hello, Brian, I've had great success working with PSI, so be sure to give them a call. They're in Pennslyvania at 215-443-8330 and ask for Rich Sabort. They can turn it around quickly for a rush fee. Good Luck. Hank Videology, Inc Where you always get P.O.M.P. and Service under…
A2500Woes
Message #216712
When my A2500 boots up, the power light blinks 6x, the screen darkens for a sec then repeats the cycle. I can get it to come all the way up but I know something must be wrong. I have three harddrives and one of them is a little slow spinning…
Dick, Please tell me more. I have an HP550C. Was it perhaps only American owners who were recipients of this roller buffing machine? Pete
#HP Deskjet Printers
Message #216647
Anybody had occasion to use the roller buffing machine that HP sent out to owners of its jet printers? Is there an Amiga program which will allow the use of the buffer? Thanks for any response. DickOUX
>Have you tried starting > HDToolbox DEVICE=ExpXDS.device from a CLI and >then clicking on "Read configuration from device" in the Change Drive Type >/Define New Drive menu? No, but I'm going to try it. I finally got it to go on the MutiDisk 150 drive. I'll let you know how…
Have you tried starting > HDToolbox DEVICE=ExpXDS.device from a CLI and then clicking on "Read configuration from device" in the Change Drive Type / Define New Drive menu? This should give you the number of tracks/sectors etc. of the drive. Georg
Yeah, but frequencies are about as close to exact as you're going to get. Now if I can get the rest of my life that close… :
Hi Hank, I wasn't talking about the 512k expansion card. I was referring to the extra RAM chip traces and holes for another four RAM chips next to the original 512k of RAM on the motherboard. In other words, 1mb RAM on the motherboard. Is it a future option which…
I thought about getting a ups, but I don't have any problems with electricity dropping out. I guess some crashes could have been caused by interference, but they could just as easily be bugs in software or my machine getting old. At work we fortunately don't have ups's, so when…
Yeah, relatively constant, it might run at 49.5hz or 50.5hz at different times of the day ( well they might not run that far out of range, but they can never be 100% accurate ). Phill
You're close. You replace the 512K Agnus chip with a one meg one and make some changes on the motherboard and you now have, with the 512K expansion card, one MB of chip ram. Don't have the exact specs for the 6a motherboard handy, but I can dig them up.…

#disc copy utility
Message #216394
If this is not the right area for this message, please forward. I have been using a utility for some time that I highly recommend for anyone wishing to make copies of their game disks. I do so with every game in case a disc decides to go belly up.…
#A4000 Repair ?
Message #216371
Anybody know of a reliable and trustworthy place to get an A4000 worked on. Or better yet, someplace that will do a motherboard swap? I think I have a bad socket for my Chip Ram on an A4000. Any help will be appreciated. Brian
Phillip,
#DataFlyer SCSI+ & BE0?
Message #216346
Hi all! I recently became a proud owner of a used A1200 with a 120 meg HD. It also has a GVP RAM/Accelerator (4 megs) and a DataFlyer SCSI+ interface (I just bought that 4 days ago). My question is about the SCSI interface. I want to hook up my…
> In the uk the power line frequency shifts quite a lot, it averages out over the day though, which is why clocks manage to keep time. The uk power supply is also never exactly 240 volts, we checked a volt meter at work the other day and got 245…
A500 RAM
Message #216279
I have an A500 rev. 6a motherboard and have noticed it has spots on the Motherboard for additional 512k RAM. What is required to install additional RAM and get it working? Is it as simple as de-soldering the board and soldering in the 4 chips? Is there a jumper that…
