Apart from the P5020 there was another computer that looked exactly like the P5020 but had a totally different machine inside. Floppys and screen were the same but the rest wasn't. It did not even have a Z80. I saw them at the computer club. They were called the 'Televerket' and were supposed to be some kind of communica- tions system for a Scandinavian PTT. I think it was also called P5900. The software for it was developed in Forth, so the Forth fans in the club were happy with them. I may have seen the card cage in this machine. You shouldn't have said you didn't have a system disk for your P5020 :) now you made me unearth my own P5020. Or at least try to. This is not an under- taking for the faint of heart. The machine is in my garage. In the back of my garage. The garage has two doors. The one in front that a car is supposed to go through (this has only happened once, in 1986 I believe) and a regular one in the middle for me. Imagine that you take a piece of chalk and attach this to the bottom of this door, at the far end, so when you open the door into the garage you draw a half-circle on the concrete floor. This circle then represents the border of how far you can walk into my garage. So I put on my coveralls, donned my old miners helmet with the strong lamp on the front and I started digging a corridor, by lifting stuff out of the way and putting it back down behind me. Soon the batteries of the lamp began to fade but just at this moment I found my P5040. There was a floppy in the right hand drive. Since this machine is compatible with the P5020 I dug it out quickly and went for the door again. Back onto safe ground I opened the P5040 and saw it had a large PCB on the bottom, and a daughtercard with two eurocard (DIN41612?) connectors for expansion cards, like your P5020, one of which had some kind of communications card in it. After being connected to the mains the machine booted at once. The disk was a CP/M 2.2 disk for the P5020. It had the spreadsheet program on it I mentioned earlier. I found my memory got warped after all those years because it turned out to be the Supercalc 2 program by Sorcim Corp. It claimed to be made for the MICOM 3003. So there you have it: Micom 3003 and P5020 are the same machine. I guess the Micom that Lawrence has is going to be the P2500. I made an image of the CP/M disk with Teledisk and wrote this image to a new disk. The P5040 also booted from this disk, but only if I put it in the right hand drive. This is a bit strange, since when you switch on the machine with no disk in it, the left hand drive lights its led and does a seek. Ah well. I can email you this Teledisk image. You need an AT PC with a 1.2MB floppy drive to write the image to a real disk, since the P5020 uses 80 track single sided drives. You can use a regular 360K disk to write the image on, if it is from a well known brand this will work. Now I'm off to dig out the digital camera so I can put a photo of this thing on my web page, it would be a same to bury it again without a photo after all this trouble :) Kees
